When your config file cannot be read

GSD distinguishes a config file that is absent from one that is present but unusable. The two used to be indistinguishable: a single trailing comma in .planning/config.json silently replaced your entire configuration with built-in defaults, and nothing said so (#1880).

Situation	What GSD does	Diagnostic
No .planning/config.json	Uses built-in defaults. This is normal.	none
File present, valid, has settings	Uses your settings.	none
File present, valid, but empty ({})	Uses built-in defaults.	none
File present but not valid JSON	Uses built-in defaults — your settings are not applied	warning: <path> is not valid JSON — its settings were NOT applied
File present but unreadable (e.g. permissions)	Uses built-in defaults — your settings are not applied	warning: <path> could not be read (EACCES) — its settings were NOT applied

The warning is printed once per file per run, so a repeated command will not spam it.

The same applies to the global ~/.gsd/defaults.json. If the project config is also unusable, the project one is reported, since that is the file you are most likely able to fix.

If you see this warning: your config was not applied. Validate the file, for example with node -e "JSON.parse(require('fs').readFileSync('.planning/config.json','utf8'))", then re-run.

Core Settings

Setting	Type	Options	Default	Description
mode	enum	interactive, yolo	interactive	yolo auto-approves decisions; interactive confirms at each step
granularity	enum	coarse, standard, fine	standard	Controls phase count: coarse (2-4), standard (4-6), fine (6-10)
model_profile	enum	quality, balanced, budget, adaptive, inherit	balanced	Model tier for each agent (see Model Profiles). adaptive was added per #1713 / #1806 and resolves the same way as the other tiers under runtime-aware profiles.
runtime	string	claude, codex, or any string	(none)	Active runtime for runtime-aware profile resolution. When set, profile tiers (opus/sonnet/haiku) resolve to runtime-native model IDs. The resolved ID is embedded into each agent's static frontmatter at install time on opencode (whose spawn_agent interface does not accept an inline model parameter, so editing model_overrides requires re-running gsd install <runtime> to take effect — see Per-Agent Overrides); other runtimes consume the resolver at spawn time. codex is the exception: it embeds no per-tier model at all. Codex is a passive / session-only model host (ADR-2313) — a ChatGPT-account session exposes only its own model, so a pinned tier model returns 400 invalid_request_error and the agent fails to spawn. Codex agents therefore inherit the session model, and only an explicit real-Codex id in model_overrides (e.g. "gpt-5.6-sol") is written into the .toml. When unset (default), model resolution is unchanged from prior versions — but the runtime GSD reports (agent_runtime) then falls through to host detection, which can resolve codex from Codex's own session environment. Detection affects reporting and the agent-installation check only; it never feeds tier resolution, which still reads this key alone. Added in v1.39; Codex behavior changed in v1.11; reporting-only host detection added in v1.11
model_profile_overrides.<runtime>.<tier>	string | object	per-runtime tier override	(none)	Override the runtime-aware tier mapping for a specific (runtime, tier). Tier is one of opus, sonnet, haiku. Value is either a model ID string (e.g. "gpt-5-pro") or { model, reasoning_effort }. See Runtime-Aware Profiles. Added in v1.39
model_policy.provider	string	openai, anthropic, anthropic-fable, google, qwen, generic	(none)	Declares the model provider. Known providers (openai, anthropic, anthropic-fable, google, qwen) unlock catalog-backed presets. generic treats all model IDs as opaque strings — no prefix inference, no reasoning-effort defaults. model_policy.runtime_tiers resolves before legacy model_profile_overrides. See Model Policy Presets. Added in v1.42 (#49)
model_policy.budget	enum	high, medium, low	(none)	Selects a budget tier when using a known provider. GSD materializes the matching catalog preset into explicit tier mappings at resolve time. Ignored when provider is generic or custom. Added in v1.42 (#49)
model_policy.high	string	model ID	(none)	High-cost tier model ID for generic/custom provider. Used when provider: "generic" or "custom". Added in v1.42 (#49)
model_policy.medium	string	model ID	(none)	Medium-cost tier model ID for generic/custom provider. Added in v1.42 (#49)
model_policy.low	string	model ID	(none)	Low-cost tier model ID for generic/custom provider. Added in v1.42 (#49)
model_policy.runtime_tiers.<runtime>.<tier>	object	{ model, reasoning_effort? }	(none)	Explicit per-runtime, per-tier model entry. tier is one of opus, sonnet, haiku (matching the existing profile tier names). reasoning_effort is forwarded only to runtimes that support it; unsupported runtimes never receive the field. Takes precedence over model_profile_overrides. Added in v1.42 (#49)
models.<phase_type>	enum	opus, sonnet, haiku, inherit	(none)	Per-phase-type model tier. Six accepted slots: planning, discuss, research, execution, verification, completion. Lets you tune at the phase level ("Opus for planning, Sonnet for the rest") without learning agent names. Resolves between model_overrides (higher) and model_profile (lower); see Per-Phase-Type Models. Added in v1.40 (#3023)
granularities.<phase_type>	enum	coarse, standard, fine	(none)	Per-phase-type granularity override. Six accepted slots: planning, discuss, research, execution, verification, completion. Lets you tune phase count at the phase level without changing the global granularity. Precedence: granularities[phaseType] (highest, enum-guarded) → granularity (global) → planning.granularity → 'standard' (hard default). Added in v1.43 (#68)
dynamic_routing.enabled	boolean	true, false	false	Master switch for dynamic routing with failure-tier escalation. When true, agents resolve to tier_models[default_tier] and escalate one tier up on orchestrator-detected soft failure. Added in v1.40 (#3024)
dynamic_routing.tier_models.<tier>	enum	opus, sonnet, haiku	(none)	Tier alias for light, standard, or heavy. Used when dynamic_routing.enabled: true. Added in v1.40
dynamic_routing.escalate_on_failure	boolean	true, false	true	When false, escalation is disabled even if enabled: true — every attempt uses the default tier. Added in v1.40
dynamic_routing.max_escalations	integer	0, 1, 2, …	1	Hard cap on retries per agent invocation. Beyond the cap the resolver returns the cap-tier model. Also caps provider_escalation. Added in v1.40
dynamic_routing.provider_escalation	string[]	ordered model IDs	(none)	Opt-in fallback providers tried when a run dies on a quota / rate limit — see provider escalation. Added in v1.43 (#2296)
project_code	string	any short string	(none)	Prefix for phase directory names (e.g., "ABC" produces ABC-01-setup/). Added in v1.31
phase_id_convention	enum	"milestone-prefixed", null	null	Phase ID naming convention. null = legacy numeric IDs (Phase 1, Phase 2). "milestone-prefixed" = globally unique IDs that encode the enclosing milestone (Phase 1-01, Phase 1-02). Run gsd-tools roadmap upgrade --convention milestone-prefixed to migrate an existing ROADMAP.md.
response_language	string	language code	(none)	Language for agent responses (e.g., "pt", "ko", "ja"). Propagates to all spawned agents for cross-phase language consistency. Added in v1.32. UAT checkpoint frames (/gsd-verify-work) render a localized banner/instruction for English, Spanish, French, German, Portuguese, Japanese, Chinese, Korean, Italian, Dutch, Polish, Russian, Ukrainian, Turkish, Hindi, Arabic, Vietnamese, and Indonesian (endonyms and ISO codes also accepted); any other value falls back to the English frame.
context_window	number	any integer	200000	Context window size in tokens. Set 1000000 for 1M-context models (e.g., claude-fable-5). Values >= 500000 enable adaptive context enrichment (full-body reads of prior SUMMARY.md, deeper anti-pattern reads). Configured via /gsd-config --advanced.
context_profile	string	dev, research, review	(none)	Execution context preset that applies a pre-configured bundle of mode, model, and workflow settings for the current type of work. Added in v1.34
claude_md_path	string	any file path	./.claude/CLAUDE.md	Custom output path for the generated CLAUDE.md file. Useful for monorepos or projects that need CLAUDE.md in a non-root location. Defaults to ./.claude/CLAUDE.md — a valid project-scoped memory location that keeps GSD-generated content from polluting a hand-crafted repo-root CLAUDE.md (#1098). An existing file without GSD markers is never overwritten unless --force is passed. Default changed from ./CLAUDE.md in v1.5. Added in v1.36
claude_md_assembly.mode	enum	embed, link	embed	Controls how managed sections are written into CLAUDE.md. embed (default) inlines content between GSD markers. link writes @.planning/<source-path> instead — Claude Code expands the reference at runtime, reducing CLAUDE.md size by ~65% on typical projects. link only applies to sections that have a real source file; workflow and fallback sections always embed. Per-block overrides: claude_md_assembly.blocks.<section> (e.g. claude_md_assembly.blocks.architecture: link). Added in v1.38
context	string	any text	(none)	Custom context string injected into every agent prompt for the project. Use to provide persistent project-specific guidance (e.g., coding conventions, team practices) that every agent should be aware of
phase_naming	string	any string	(none)	Custom prefix for phase directory names. When set, overrides the auto-generated phase slug (e.g., "feature" produces feature-01-setup/ instead of the roadmap-derived slug)
brave_search	boolean	true/false	auto-detected	Override auto-detection of Brave Search API availability. When unset, GSD checks for BRAVE_API_KEY env var or ~/.gsd/brave_api_key file
firecrawl	boolean	true/false	auto-detected	Override auto-detection of Firecrawl API availability. When unset, GSD checks for FIRECRAWL_API_KEY env var or ~/.gsd/firecrawl_api_key file
exa_search	boolean	true/false	auto-detected	Override auto-detection of Exa Search API availability. When unset, GSD checks for EXA_API_KEY env var or ~/.gsd/exa_api_key file
tavily_search	boolean	true/false	auto-detected	Override auto-detection of Tavily Search API availability. When unset, GSD checks for TAVILY_API_KEY env var or ~/.gsd/tavily_api_key file
ref_search	boolean	true/false	auto-detected	Override auto-detection of Ref search API availability. When unset, GSD checks for REF_API_KEY env var or ~/.gsd/ref_api_key file
perplexity	boolean	true/false	auto-detected	Override auto-detection of Perplexity API availability. When unset, GSD checks for PERPLEXITY_API_KEY env var or ~/.gsd/perplexity_api_key file
jina	boolean	true/false	true	Override auto-detection of Jina API availability. Jina is a terminal fallback in the docs waterfall and defaults to available (true); GSD checks for JINA_API_KEY env var or ~/.gsd/jina_api_key file when an explicit override is needed
search_gitignored	boolean	true/false	false	Legacy top-level alias for planning.search_gitignored. Prefer the namespaced form; this alias is accepted for backward compatibility

Note: granularity was renamed from depth in v1.22.3. Existing configs are auto-migrated.

Integration Settings

Configured interactively via /gsd-config --integrations. These are connectivity settings — API keys and cross-tool routing — and are intentionally kept separate from /gsd-settings (workflow toggles).

Search API keys

API key fields accept a string value (the key itself). They can also be set to the sentinels true/false/null to override auto-detection from env vars / ~/.gsd/*_api_key files (legacy behavior, see rows above).

Setting	Type	Default	Description
brave_search	string | boolean | null	null	Brave Search API key used for web research. Displayed as ****<last-4> in all UI / config-set output; never echoed plaintext
firecrawl	string | boolean | null	null	Firecrawl API key for deep-crawl scraping. Masked in display
exa_search	string | boolean | null	null	Exa Search API key for semantic search. Masked in display
tavily_search	string | boolean | null	null	Tavily Search API key used in the web-discovery waterfall. Masked in display
ref_search	string | boolean | null	null	Ref search API key used in the docs-discovery waterfall. Masked in display
perplexity	string | boolean | null	null	Perplexity API key used in the web-discovery waterfall. Masked in display
jina	string | boolean | null	null	Jina API key (docs / scrape fallback). Masked in display

Masking convention (gsd-core/bin/lib/secrets.cjs): keys 8+ characters render as ****<last-4>; shorter keys render as ****; null/empty renders as (unset). Plaintext is written as-is to .planning/config.json — that file is the security boundary — but the CLI, confirmation tables, logs, and AskUserQuestion descriptions never display the plaintext. This applies to the config-set command output itself: config-set brave_search <key> returns a JSON payload with the value masked.

Code-review CLI routing

review.models.<cli> maps a reviewer flavor to a bare model id, which is injected into the CLI's own model flag (--model, -m, …) when the reviewer is invoked.

The key suffix is not always the lane slug. Each lane declares the config key it reads, and one shipped lane already differs: the Antigravity lane's slug is antigravity but its key is review.models.agy, after the CLI's own name. Consult the table below rather than deriving the key from the flag.

Setting	Type	Default	Description
review.models.claude	string	(session model)	Model id for Claude-flavored review. Defaults to the session model when unset
review.models.codex	string	null	Model id for Codex review (injected into --model), e.g. "gpt-5"
review.models.gemini	string	null	Model id for Gemini review (injected into -m), e.g. "gemini-2.5-pro"
review.models.opencode	string	null	Model id for OpenCode review (injected into --model), e.g. "claude-sonnet-4"
review.models.kimi-code	string	null	Model id for Kimi Code review (injected into -m)

Ownership. These keys are owned by their reviewer-lane capabilities rather than the central config schema — review.models.ollama belongs to the ollama capability, review.ollama_host to the same, and so on. Key names and existing .planning/config.json files are unchanged; only which schema validates them moved.

One consequence follows: <cli> must now name a declared reviewer lane. Previously any slug matching [a-zA-Z0-9_-]+ was accepted, so a typo or a key left over from a removed reviewer validated silently and was never read. Such a key is now rejected by config-set. The declared lanes are gemini, claude, codex, opencode, agy (the Antigravity lane — its key suffix is the CLI's own name, not the lane slug), ollama, lm_studio and llama_cpp.

The same applies to review.max_prompt_tokens_per_reviewer.<slug>. review.max_prompt_tokens (the global default), review.default_reviewers and review.reviewer_instances describe policy across lanes rather than one lane's behavior, so they remain central and are unaffected.

Reviewer defaults for /gsd-review

Use review.default_reviewers to scope the no-flag /gsd-review run to a subset of detected reviewers.

Setting	Type	Default	Description
review.default_reviewers	string[] | null	null (all detected reviewers)	Optional default subset for no-flag /gsd-review, e.g. ["gemini","codex"]. Entries may be built-in reviewer slugs or configured review.reviewer_instances names. Precedence is: explicit reviewer flags > --all > review.default_reviewers > all detected. Unknown slugs are ignored with a warning when no instances are configured; with review.reviewer_instances present, unknown entries are hard errors to catch typoed instance names. Known-but-undetected slugs are ignored with an info note; empty arrays are rejected by config-set. This leniency is specific to the configured default: a reviewer named by an explicit CLI flag that cannot run is an error, not an info note.

Example:

{
  "review": {
    "default_reviewers": ["gemini", "codex"]
  }
}

Reviewer instances for /gsd-review (#1517)

Use review.reviewer_instances to run one model-capable adapter as several independent reviewer identities — e.g. two OpenCode-backed reviews with different models in a single /gsd-review pass. Each entry maps an instance name to { cli, model?, agent? }.

Setting	Type	Default	Description
review.reviewer_instances.<name>.cli	string	(required)	A known reviewer adapter the instance reuses (e.g. opencode). Must be a built-in slug; never an arbitrary shell command.
review.reviewer_instances.<name>.model	string	(adapter default)	Opaque provider/model id passed through verbatim to the adapter's --model. GSD does not parse it.
review.reviewer_instances.<name>.agent	string	(none)	Opaque agent name; honoured only by adapters with a native agent concept (OpenCode --agent in v1).

Instance names must match ^[a-z0-9][a-z0-9-]*$ and must not equal a built-in reviewer slug. Instances participate ONLY through review.default_reviewers (there are no per-instance CLI flags). Instance references are expanded before built-in slugs; an instance is available iff its cli is detected. An entry that is neither a defined instance nor a built-in slug is a hard error (a typo'd instance name must be loud). When two or more selected instances share the same cli, REVIEWS.md prints a one-line shared-adapter caveat so review consensus is not silently overstated. See ADR-1517.

Example:

{
  "review": {
    "reviewer_instances": {
      "opencode-deepseek": { "cli": "opencode", "model": "deepseek/deepseek-v4-pro", "agent": "review" },
      "opencode-mimo": { "cli": "opencode", "model": "xiaomi/mimo-v2.5-pro" }
    },
    "default_reviewers": ["opencode-deepseek", "opencode-mimo", "codex"]
  }
}

Set each field via config-set:

gsd config-set review.reviewer_instances.opencode-deepseek.cli opencode
gsd config-set review.reviewer_instances.opencode-deepseek.model deepseek/deepseek-v4-pro
gsd config-set review.reviewer_instances.opencode-deepseek.agent review
gsd config-set review.default_reviewers '["opencode-deepseek","opencode-mimo","codex"]'

Agent-skill injection (dynamic)

agent_skills.<agent-type> extends the agent_skills map documented below. Slug is validated against [a-zA-Z0-9_-]+ — no path separators, no whitespace, no shell metacharacters. Configured interactively via /gsd-config --integrations.

---

Workflow Toggles

All workflow toggles follow the absent = enabled pattern. If a key is missing from config, it defaults to true.

Setting	Type	Default	Description
workflow.research	boolean	true	Domain investigation before planning each phase
workflow.plan_check	boolean	true	Plan verification loop (up to 3 iterations)
workflow.verifier	boolean	true	Post-execution verification against phase goals
workflow.auto_advance	boolean	false	Auto-chain discuss → plan → execute without stopping
workflow.nyquist_validation	boolean	true	Test coverage mapping during plan-phase research
workflow.ui_phase	boolean	true	Generate UI design contracts for frontend phases
workflow.ui_safety_gate	boolean	true	Prompt to run /gsd-ui-phase for frontend phases during plan-phase
workflow.assumption_delta	boolean	true	Advisory architecture checkpoint during planning. When a phase makes something plural, optional, or chosen that used to be singular, required, or derived (e.g. a second auth method, a required field becoming optional, a constant becoming a parameter), the planner is prompted to re-ask whether the primary key / identity model still names the right thing (promote the new general representation vs. add it alongside). Non-blocking; fires only on a detected signal. Bare "or" is intentionally excluded (prose false-positives). Inspect a phase with gsd query assumption-delta scan <phase>. Added in #1561
workflow.ui_review	boolean	true	Run visual quality audit (/gsd-ui-review) after phase execution in autonomous mode. When false, the UI audit step is skipped.
workflow.node_repair	boolean	true	Autonomous task repair on verification failure
workflow.node_repair_budget	number	2	Max repair attempts per failed task
workflow.smart_zone_tokens	number	100000	Smart-zone token budget for phase-effort estimation (#2630, ADR-2629). A phase whose estimate exceeds this is flagged with a split recommendation — advisory only, never a block. This is a policy default, not a benchmark constant: LLM output quality degrades before the advertised context window is full, but the effective ceiling is model-, task-, and distractor-dependent, so no universal number exists. Lower it for models that degrade early; the estimate-vs-actual calibration loop corrects the figure per project over time. Must be a positive integer.
workflow.research_before_questions	boolean	false	Run research before discussion questions instead of after
workflow.discuss_mode	string	'discuss'	Controls how /gsd-discuss-phase gathers context. 'discuss' (default) asks questions one-by-one. 'assumptions' reads the codebase first, generates structured assumptions with confidence levels, and only asks you to correct what's wrong. Added in v1.28
workflow.max_discuss_passes	number	3	Maximum number of question rounds in discuss-phase before the workflow stops asking. Useful in headless/auto mode to prevent infinite discussion loops.
workflow.skip_discuss	boolean	false	When true, /gsd-autonomous bypasses the discuss-phase entirely, writing minimal CONTEXT.md from the ROADMAP phase goal. Useful for projects where developer preferences are fully captured in PROJECT.md/REQUIREMENTS.md. Added in v1.28
workflow.text_mode	boolean	false	Replaces AskUserQuestion TUI menus with plain-text numbered lists. Required for Claude Code remote sessions (/rc mode) where TUI menus don't render. Can also be set per-session with --text flag on discuss-phase. Added in v1.28
workflow.use_worktrees	boolean	true	When false, disables git worktree isolation for parallel execution. Users who prefer sequential execution or whose environment does not support worktrees can disable this. Added in v1.31. Branch-divergence note: when your branch has diverged from origin/HEAD, GSD auto-degrades to sequential and prints a warning. See worktree.baseRef to restore parallel execution on a diverged branch. Per-runtime note: whether this key can be honored depends on the runtime's declared dispatch.isolation capability, not on its name (#2584). Runtimes whose own harness isolates each executor (Claude Code, Cursor) run parallel worktrees natively; runtimes exposing a headless exec with an explicit working directory (Codex, OpenCode, Kimi, Kimi Code) get worktrees GSD itself creates and merges — where a dispatch site can only drive the harness model, those hosts degrade to sequential with a warning rather than aborting. Every other runtime declares no isolation primitive, and forcing use_worktrees: true there still fails closed before any executor dispatch. See Executor isolation per runtime.
workflow.worktree_skip_hooks	boolean	false	When true, executor agents in worktree mode pass --no-verify (skipping pre-commit hooks) and post-wave hook validation runs against the merged result instead. Opt-in escape hatch for projects whose hooks cannot run in agent worktrees. Default false runs hooks on every commit (#2924).
workflow.code_review	boolean	true	Enable /gsd-code-review and /gsd-code-review --fix commands. When false, the commands exit with a configuration gate message. Added in v1.34
workflow.code_review_depth	string	standard	Default review depth for /gsd-code-review: quick (pattern-matching only), standard (per-file analysis), or deep (cross-file with import graphs). Can be overridden per-run with --depth=. Added in v1.34
workflow.plan_bounce	boolean	false	Run external validation script against generated plans. When enabled, the plan-phase orchestrator pipes each PLAN.md through the script specified by plan_bounce_script and blocks on non-zero exit. Added in v1.36
workflow.plan_bounce_script	string	(none)	Path to the external script invoked for plan bounce validation. Receives the PLAN.md path as its first argument. Required when plan_bounce is true. Added in v1.36
workflow.plan_bounce_passes	number	2	Number of sequential bounce passes to run. Each pass feeds the previous pass's output back into the validator. Higher values increase rigor at the cost of latency. Added in v1.36
workflow.post_planning_gaps	boolean	true	Unified post-planning gap report (#2493). After all plans are generated and committed, scans REQUIREMENTS.md and CONTEXT.md <decisions> against every PLAN.md in the phase directory, then prints one Source | Item | Status table. Word-boundary matching (REQ-1 vs REQ-10) and natural sort (REQ-02 before REQ-10). Non-blocking — informational report only. Set to false to skip Step 13e of plan-phase.
workflow.plan_review_convergence	boolean	false	Enable the /gsd-plan-review-convergence command. Disabled by default — the command exits with an enable instruction when this key is false. The command automates the manual plan→review→replan loop: it spawns configured reviewers (Codex, Gemini, Claude, OpenCode, Ollama, LM Studio, llama.cpp), counts unresolved HIGH concerns and actionable MEDIUM/LOW findings via the CYCLE_SUMMARY contract, replans with --reviews feedback, and repeats until converged or max cycles reached. Enable with gsd config-set workflow.plan_review_convergence true. Added in v1.39
workflow.plan_chunked	boolean	false	Enable chunked planning mode. When true (or when --chunked flag is passed to /gsd-plan-phase), the orchestrator splits the single long-lived planner Task into a short outline Task followed by N short per-plan Tasks (~3-5 min each). Each plan is committed individually for crash resilience. If a Task hangs and the terminal is force-killed, rerunning with --chunked resumes from the last completed plan. Particularly useful on Windows where long-lived Tasks may hang on stdio. Added in v1.38
workflow.code_review_command	string	(none)	Shell command for external code review integration in /gsd-ship. Receives changed file paths via stdin. Non-zero exit blocks the ship workflow. Added in v1.36
workflow.tdd_mode	boolean	false	Enable TDD pipeline as a first-class execution mode. When true, the planner aggressively applies type: tdd to eligible tasks (business logic, APIs, validations, algorithms) and the executor enforces RED/GREEN/REFACTOR gate sequence. An end-of-phase collaborative review checkpoint verifies gate compliance. Added in v1.36
workflow.mvp_mode	boolean	false	Persist the MVP-mode flag in config so every phase defaults to MVP framing without requiring --mvp on the CLI. Resolved via the precedence chain: --mvp CLI flag → ROADMAP.md **Mode:** mvp field → this config value → false. When true, the planner, executor, verifier, and discovery surfaces treat the phase as an MVP vertical slice (UI → API → DB) of one user-visible capability instead of a horizontal layer.
workflow.human_verify_mode	string	'end-of-phase'	Controls human verification checkpoints. 'end-of-phase' (default since #3309) suppresses checkpoint:human-verify tasks and embeds checks into <verify><human-check> blocks for end-of-phase review. 'mid-flight' restores blocking checkpoint tasks. checkpoint:decision and checkpoint:human-action are unaffected. See Checkpoints Reference.
workflow.context_guard_mode	string	'warn'	Context exhaustion guard for execute-phase. Before each wave, the orchestrator self-assesses context pressure using the degradation signals defined in context-budget.md. 'warn' (default) emits a warning and recommends /gsd-pause-work when POOR tier (70%+) is detected. 'auto' automatically invokes /gsd-pause-work before the next wave. 'off' disables the guard. Set via: gsd config-set workflow.context_guard_mode auto. Added in #1452.
workflow.cross_ai_execution	boolean	false	Delegate phase execution to an external AI CLI instead of spawning local executor agents. Useful for leveraging a different model's strengths for specific phases. Added in v1.36
workflow.cross_ai_command	string	(none)	Shell command template for cross-AI execution. Receives the phase prompt via stdin. Must produce SUMMARY.md-compatible output. Required when cross_ai_execution is true. Added in v1.36
workflow.cross_ai_timeout	number	300	Timeout in seconds for cross-AI execution commands. Prevents runaway external processes. Added in v1.36
workflow.test_gate_timeout	number	600	Wall-clock timeout (seconds) for a verification test gate; a watch-mode runner (vitest/jest) that never exits is aborted after this budget instead of hanging the orchestrator (#1857)
workflow.ai_integration_phase	boolean	true	Enable the /gsd-ai-integration-phase command. When false, the command exits with a configuration gate message
workflow.api_coverage_gate	boolean	true	Require an explicit API-coverage decision before a phase that integrates an external API/SDK/service can seal. At plan:pre the planner is prompted to produce a COVERAGE.md matrix (full coverage by default, every opt-out reasoned); at verify:pre a blocking gate fails the seal unless the matrix is complete. Independent of ai_integration_phase (#1562)
workflow.auto_prune_state	boolean	false	When true, automatically prune stale entries from STATE.md at phase boundaries instead of prompting
workflow.pattern_mapper	boolean	true	Run the gsd-pattern-mapper agent between research and planning to map new files to existing codebase analogs
workflow.subagent_timeout	number	300000	Timeout in milliseconds for parallel subagent tasks (e.g. codebase mapping). Increase for large codebases or slower models. Default: 300000 (5 minutes)
executor.stall_detect_interval_minutes	number	5	Minutes between executor stall checks while an executor agent is active. The execute-phase orchestrator uses this cadence to inspect recent commits and avoid waiting forever on a silent agent.
executor.stall_threshold_minutes	number	10	Minutes without executor completion or expected-branch commit activity before execute-phase offers recovery choices for a possible stalled executor.
planner.stall_detect_interval_minutes	number	5	Minutes between planner/plan-checker stall checks while a planner or plan-checker agent is active. The plan-phase orchestrator uses this cadence to inspect on-disk *-PLAN.md activity and avoid waiting forever on a silent agent (#2650).
planner.stall_threshold_minutes	number	10	Minutes without a completion marker or fresh on-disk plan activity before plan-phase automatically surfaces the accept-plans/retry/stop recovery choice for a possible stalled planner or plan-checker (#2650).
workflow.inline_plan_threshold	number	3	Maximum number of tasks in a phase before the planner generates a separate PLAN.md file instead of inlining tasks in the prompt
workflow.drift_threshold	number	3	Minimum number of new structural elements (new directories, barrel exports, migrations, route modules) before the codebase-drift gate takes action. The gate runs at two points: plan:pre (before /gsd-plan-phase plans — non-blocking, warn-only, so plans are authored against a fresh STRUCTURE.md) and execute:wave:post (after /gsd-execute-phase — honors workflow.drift_action). See #2003. Added in v1.39
workflow.drift_action	string	warn	What to do when workflow.drift_threshold is exceeded at execute:wave:post (after /gsd-execute-phase). warn prints a message suggesting /gsd-map-codebase --paths …; auto-remap spawns gsd-codebase-mapper scoped to the affected paths. The plan:pre pre-check is always warn-only regardless of this setting — it never auto-spawns the mapper at plan entry. Added in v1.39
workflow.plan_drift_precheck	boolean	true	Enable the non-blocking codebase-drift pre-check at plan:pre, before /gsd-plan-phase spawns the planner. Surfaces a stale STRUCTURE.md (drift over workflow.drift_threshold) as a warn-only advisory pointing to /gsd-map-codebase; never blocks planning, never spawns the mapper. Separate from the execute:wave:post gates so autonomous/CI runs can silence the plan-time advisory while keeping execute-time drift detection on. Added in v1.6.0. See #1592.
workflow.build_command	string	(none)	Shell command to build the project in the post-merge build gate (Step A of step 5.6 in execute-phase). When unset, the gate auto-detects: Xcode (.xcodeproj present) → xcodebuild build, Makefile with build: target → make build, Justfile → just build, Cargo.toml → cargo build, go.mod → go build ./..., Python → python -m py_compile, package.json with build script → npm run build. Runs with a 5-minute timeout; failure increments WAVE_FAILURE_COUNT. Added in v1.39
workflow.test_command	string	(none)	Shell command to run the project's test suite in the post-merge test gate (Step B of step 5.6 in execute-phase) and the regression gate. When unset, the gate auto-detects: Xcode (.xcodeproj present) → xcodebuild test, Makefile with test: target → make test, Justfile → just test, package.json → npm test, Cargo.toml → cargo test, go.mod → go test ./..., Python → python -m pytest. Runs with a 5-minute timeout; failure increments WAVE_FAILURE_COUNT. Added in v1.39

Worktree Settings

File: .claude/settings.local.json — not .planning/config.json. Unlike all other keys in this reference, worktree.* settings live in the Claude Code runtime settings file. Fresh installs and upgrades auto-set worktree.baseRef: "head" there (no-clobber) when workflow.use_worktrees is enabled. The key can also be set via gsd-tools worktree set-baseref.

Setting	Type	Default	Description
worktree.baseRef	string	(unset)	Controls which ref the worktree-based parallel executor uses as the base when creating new phase/wave worktrees. When unset, the executor bases new worktrees on the repository default branch (origin/HEAD); if the current branch has diverged, execute-phase auto-degrades to sequential execution rather than halting (as of v1.4.0). Set to "head" to base new worktrees on the local HEAD instead — the appropriate choice when working on a branch that has diverged from the default branch, as it prevents the exit-42 base-mismatch halt and allows wave-based parallel execution to proceed normally. See Fix the worktree base-mismatch (exit 42) error.

Code Quality Settings

The code_quality.* namespace gates optional structural-analysis tooling that augments /gsd-code-review. Settings are additive: each tool is independently opt-in and off by default.

Setting	Type	Default	Description
code_quality.fallow.enabled	boolean	false	Enables fallow structural pre-pass for /gsd-code-review. When false, no fallow binary probe or JSON artifact is produced.
code_quality.fallow.scope	string	phase	Scope for fallow analysis: phase (current review file scope) or repo (entire repository).
code_quality.fallow.profile	string	standard	Strictness preset for the fallow pre-pass (minimal, standard, strict). Fallow has no native profile concept, so this maps to its --max-crap complexity threshold: minimal→50, standard→30, strict→15 (lower = stricter).
code_quality.fallow.mcp	boolean	false	Reserved — not yet implemented. When true, enables MCP-backed structural findings mode for runtimes that support MCP server routing. Setting this to true is currently a no-op and emits a runtime warning.

Ship Settings

ship.pr_body_sections adds additional PR body sections for project-specific PRD/PR body content in /gsd-ship without editing gsd-core/workflows/ship.md.

For a user guide with onboarding examples and troubleshooting, see Custom PR Body Sections.

This list is append-only: configured entries are added after the core Summary, Changes, Requirements Addressed, Verification, and Key Decisions sections. They cannot replace, remove, or reorder required sections.

Recommended lean/agile PRD uses include user stories, acceptance criteria, Definition of Done or release criteria, risks and dependencies, success metrics, and stakeholder review notes. Keep these sections short and evidence-oriented so the PR body remains a living release artifact rather than a static requirements dump.

Each entry supports:

Field	Type	Default	Description
heading	string	required	Markdown section heading rendered as ## {heading}. Must be a single line.
enabled	boolean	true	When false, onboarding can keep a candidate section in config without rendering it in generated PR bodies.
source	string	(none)	Optional fallback chain of planning artifact headings, such as PLAN.md ## Risks || VERIFICATION.md ## Manual Checks. Allowed artifacts are ROADMAP.md, PLAN.md, SUMMARY.md, VERIFICATION.md, STATE.md, REQUIREMENTS.md, and CONTEXT.md.
template	string	(none)	Literal Markdown with closed tokens: {phase_number}, {phase_name}, {phase_dir}, {base_branch}, {padded_phase}.
fallback	string	(none)	Literal Markdown used when source yields no content and no template is provided.

At least one of source, template, or fallback is required for each section. The default is [], so existing projects keep their current /gsd-ship output until onboarding adds enabled entries.

Example:

{
  "ship": {
    "pr_body_sections": [
      {
        "heading": "User Stories & Acceptance Criteria",
        "enabled": true,
        "source": "REQUIREMENTS.md ## User Stories || REQUIREMENTS.md ## Acceptance Criteria",
        "fallback": "- Acceptance criteria are covered by the linked requirements and verification evidence."
      },
      {
        "heading": "Risks & Rollback",
        "enabled": true,
        "source": "PLAN.md ## Risks || PLAN.md ## Rollback",
        "fallback": "- Rollback: revert this PR."
      },
      {
        "heading": "Stakeholder Sign-off",
        "enabled": false,
        "template": "- Product owner: pending for {phase_name}"
      }
    ]
  }
}

Common Setting Combinations

The following combinations of mode, granularity, model_profile, and workflow toggles are commonly used together. See Configure model profiles for setup guidance.

Scenario	mode	granularity	profile	research	plan_check	verifier
Prototyping	yolo	coarse	budget	false	false	false
Normal development	interactive	standard	balanced	true	true	true
Production release	interactive	fine	quality	true	true	true

---

Planning Settings

Setting	Type	Default	Description
planning.commit_docs	boolean	true	Whether .planning/ files are committed to git
planning.search_gitignored	boolean	false	Add --no-ignore to broad searches to include .planning/
planning.sub_repos	array of strings	[]	Paths of nested sub-repos relative to the project root. When set, GSD-aware tooling scopes phase-lookup, path-resolution, and commit operations per sub-repo instead of treating the outer repo as a monorepo

Project-Root Resolution in Multi-Repo Workspaces

When sub_repos is set and gsd-tools.cjs or gsd-tools query is invoked from inside a listed child repo, both CLIs walk up to the parent workspace that owns .planning/ before dispatching handlers. Resolution order (checked at each ancestor up to 10 levels, never above $HOME):

1. If the starting directory already has its own .planning/, it is the project root (no walk-up).
2. Parent has .planning/config.json listing the starting directory's top-level segment in sub_repos (or the legacy planning.sub_repos shape).
3. Parent has .planning/config.json with legacy multiRepo: true and the starting directory is inside a git repo.
4. Parent has .planning/ and an ancestor up to the candidate parent contains .git (heuristic fallback).

If none match, the starting directory is returned unchanged. Explicit --project-dir /path/to/workspace is idempotent under this resolution.

Auto-Detection

If .planning/ is in .gitignore, commit_docs is automatically false regardless of config.json. This prevents git errors.

---

Hook Settings

Setting	Type	Default	Description
hooks.context_warnings	boolean	true	Show context window usage warnings via context monitor hook
hooks.workflow_guard	boolean	false	Warn when file edits happen outside GSD workflow context (advises using /gsd-quick or /gsd-fast)
statusline.show_last_command	boolean	false	Append last: /<cmd> suffix to the statusline showing the most recently invoked slash command. Opt-in; reads the active session transcript to extract the latest <command-name> tag (closes #2538)
statusline.context_position	string	"end"	Position of the context-window meter. "end" (default) renders at line tail; "front" renders immediately after the model name so the meter stays visible in narrow terminals. Closes #2937
statusline.show_context_tokens	boolean	false	Append the absolute token count (e.g. (156k)) after the context meter's percentage. Sums input, cache-creation, cache-read, and output tokens from the hook payload — a broader basis than the meter's percentage (which excludes output tokens), so the two figures can diverge slightly. Opt-in; the meter is unchanged when the flag is absent
statusline.state_format	string	"full"	Format of the GSD-state segment. "full" (default) is the existing rendering with milestone name and progress bar. "compact" renders <version> · P<phase>/<total> · <status> (e.g. v1.12 · P7/12 · executing) — drops the milestone name and bar, and collapses narrative statuses to the canonical keyword set from normalizeStateStatus() (paused — the canonical stuck state — renders uppercase as PAUSED)
statusline.show_git	boolean	false	Append a git segment after the directory: current branch plus compact work-state markers (+staged ~unstaged ?untracked ↑ahead ↓behind, or ✓ when clean and in sync). One git status --porcelain=v2 call per render; the segment is absent outside a git repo or when git is unavailable

The prompt injection guard hook (gsd-prompt-guard.js) is always active and cannot be disabled — it's a security feature, not a workflow toggle.

Private Planning Setup

When planning.commit_docs is false and .planning/ is listed in .gitignore, GSD treats planning artefacts as local-only. planning.search_gitignored: true ensures broad searches still include the .planning/ directory in this configuration. See Configure private planning for setup steps.

---

Agent Skills Injection

Inject custom skill files into GSD subagent prompts. Skills are read by agents at spawn time, giving them project-specific instructions beyond what CLAUDE.md provides.

Setting	Type	Default	Description
agent_skills	object	{}	Map of agent types to arrays of skill entries
agent_skills_security.trusted_global_roots	array of strings	[]	Opt-in allowlist of additional trusted directories for global: skills. See Trusted global skill roots

Configuration

Add an agent_skills section to .planning/config.json mapping agent types to arrays of skill entries:

{
  "agent_skills": {
    "gsd-executor": [
      "skills/testing-standards",
      "global:shared-conventions",
      "global:coderabbit:code-review"
    ],
    "gsd-planner": ["skills/architecture-rules"],
    "gsd-verifier": ["skills/acceptance-criteria"]
  }
}

Skill Entry Forms

Each element in the array is one of three forms:

Form	Example	Resolution
Project-relative path	"skills/my-skill"	Resolves to <project>/skills/my-skill/SKILL.md, injected as an @-include
Global personal skill	"global:<name>"	Resolves to ~/.claude/skills/<name>/SKILL.md, injected as an @-include
Plugin-provided skill (Claude only)	"global:<plugin>:<skill>"	A Claude Code plugin skill, loaded by name via the Skill tool at agent spawn time

Project-relative paths must point to a directory containing a SKILL.md file. Paths are validated for safety (no traversal outside the project root).

Global personal skills (global:<name>) resolve against the runtime's global skills directory (e.g. ~/.claude/skills/). Symlink-escape protection applies unless the target is listed in agent_skills_security.trusted_global_roots.

Plugin-provided skills (global:<plugin>:<skill>) follow the namespaced form seg(:seg)*, where each segment is one or more alphanumeric characters, underscores, or hyphens joined by single colons (e.g. global:coderabbit:code-review). This form is Claude-only: on the Claude runtime GSD emits a Skill-tool load directive in the agent's <agent_skills> block so the agent loads the skill by name via the Skill tool, and Claude Code resolves the plugin:skill namespace. On all other runtimes the entry is skipped with a warning — the plugin/Skill-tool model is specific to Claude Code and has no equivalent elsewhere.

Why load by name rather than path? Claude Code's plugin cache is versioned and ephemeral, so there is no stable filesystem path to @-include. Loading by namespaced name via the Skill tool lets Claude Code's own resolver locate the current version of the plugin skill at runtime.

The plugin must already be installed in the user's Claude Code environment (/plugin install …). GSD only references the skill by its namespaced name and does not read or validate the plugin cache itself.

Supported Agent Types

Any GSD agent type can receive skills. The agent types that consume agent_skills are the GSD sub-agents the workflows dispatch. There are 22 consumer agents in total, including:

• gsd-executor — executes implementation plans
• gsd-planner — creates phase plans
• gsd-plan-checker — verifies plan quality
• gsd-verifier — post-execution verification
• gsd-phase-researcher — phase research
• gsd-project-researcher — new-project research
• gsd-debugger — diagnostic agents
• gsd-codebase-mapper — codebase analysis
• gsd-code-reviewer — code review
• gsd-ui-researcher — UI design contract creation
• gsd-ui-checker — UI spec verification
• gsd-ui-auditor — UI audit
• gsd-roadmapper — roadmap creation
• gsd-research-synthesizer — research synthesis
• and others (see tests/agent-skills.test.cjs CONSUMER_AGENTS list for the full 22)

The Skill tool is granted to consumer agents deliberately and is instruction-bounded — agents use it only to load the skills listed in the <agent_skills> block.

How It Works

Skills reach a consumer agent through two cooperating seams (dual injection — see ADR 1866):

1. Orchestrator-side (primary on Claude Code). At spawn time, workflows call gsd-tools query agent-skills <type> (or legacy node gsd-tools.cjs agent-skills <type>) in their bash init and interpolate the resulting <agent_skills> block into the Task()/Agent() prompt. This is established across ~25 workflows.

2. Agent-side self-load (durable fallback). Each of the 22 consumer agents also self-loads in its own mandatory init step — it runs gsd_run query agent-skills <its-type> and Reads every listed SKILL.md per gsd-core/references/agent-skills-bootstrap.md. This is the path that works on every runtime, including Cursor, where Skill()-delegated workflow bash init does not reliably execute and /gsd-autonomous delegates via flat Skill() calls.

Dedup guard. If an agent's prompt already contains an <agent_skills> block (orchestrator already injected one), the agent skips self-load — so on runtimes where both seams run (Claude Code), the prompt never carries two copies. query agent-skills is read-only and idempotent: it exits 0 with an empty block when nothing is configured for the type, so self-load is zero-overhead for unconfigured agents.

For project-relative and global personal skills, entries appear as @-includes:

<agent_skills>
Read these user-configured skills:
- @skills/testing-standards/SKILL.md
- @/Users/you/.claude/skills/shared-conventions/SKILL.md
</agent_skills>

For a mixed config (path-resolvable and plugin-provided skills together), entries appear interleaved in config order in a single section:

<agent_skills>
Read these user-configured skills:
- @skills/testing-standards/SKILL.md
- Load the `coderabbit:code-review` skill via the Skill tool before proceeding (plugin-provided).
</agent_skills>

If no skills are configured, the block is omitted (zero overhead).

CLI

Set skills via the CLI:

gsd-tools query config-set agent_skills.gsd-executor '["skills/my-skill"]'

See How to attach a plugin-provided skill to a GSD agent for a step-by-step walkthrough of the global:plugin:skill form.

Trusted Global Skill Roots (agent_skills_security.trusted_global_roots)

Widen the symlink-safety boundary for global: skills by declaring additional trusted root directories.

Purpose

By default, a global:<name> skill whose SKILL.md real path (after resolving symlinks) escapes the runtime's global skills directory (e.g. ~/.claude/skills/) is rejected as a symlink-escape. agent_skills_security.trusted_global_roots lets you declare additional trusted root directories so symlinked skills whose real target lives under one of them are accepted.

Common use case: a single source-of-truth skills directory elsewhere on disk (e.g. ~/shared/skills) symlinked into ~/.claude/skills/ so git pull or rsync keeps a team's skills up to date without maintaining copies.

Configuration

{
  "agent_skills_security": {
    "trusted_global_roots": [
      "~/shared/skills",
      "/opt/shared-skills"
    ]
  }
}

How It Works

• Default [] — behavior is byte-identical to omitting the option entirely: only skills whose real SKILL.md path resolves inside the default global skills directory are accepted.
• Absolute or tilde-prefixed paths only. Each entry must be an absolute path (/opt/shared-skills) or a ~/~/-prefixed path (tilde expands to your home directory). Project-relative paths are rejected, so an untrusted repo's .planning/config.json cannot point trust at a directory inside itself.
• realpathSync at load time. Each declared root is resolved with realpathSync on every run, so trust follows the real target and cannot silently drift if a root itself later becomes a symlink. Non-existent or unreadable roots are dropped without error.
• Dangerously broad roots are refused. The filesystem root (/), drive or UNC roots, and your home directory itself cannot be declared as trusted roots — these would make the allowlist meaningless.
• Acceptance rule. A skill is accepted if and only if its real SKILL.md path lies inside the default global skills directory OR inside one of the resolved trusted roots. Skills resolving outside all of these are still rejected.
• Audit note. When a skill is accepted via a trusted root rather than the default global skills directory, a [agent-skills] NOTE: line is written to stderr so the widened boundary remains visible.

Security note: trusted_global_roots is read from the project-local .planning/config.json. Only add roots you control and trust. Declaring a broad shared directory widens which symlinked global skills will load for every agent in this project.

CLI

gsd config-set agent_skills_security.trusted_global_roots '["~/shared/skills"]'

Setting the parent object (agent_skills_security) directly is not supported; use the dot-notation leaf form shown above.

Capability Trust (capabilities.*)

Policy for installing and updating third-party capabilities (ADR-1244). These keys govern the trust gate; they have no effect if you only ever use the native first-party capabilities shipped with GSD. They are policy inputs read by the gsd capability command flow, which passes the resulting decision into the capability lifecycle — strict_known_registries gates whether a source may be installed at all; auto_update is consulted by the update/outdated flow (which always re-prompts when a new version's executable surface set changes). The full rationale — including why there is no sandbox — is in The capability trust model.

Setting	Type	Default	Description
capabilities.strict_known_registries	array | null	null	Allowlist gating which sources third-party capabilities may be installed from. null (default) is permissive: external installs (git / npm / tarball) are allowed and each still passes the consent + integrity gate. [] (explicit empty array) is lockdown: all external installs are blocked — only local-filesystem installs are permitted (managed/enterprise mode). A non-empty list is a host-based allowlist: only sources whose host matches an entry (exact host or a subdomain of it — github.com matches api.github.com but never evilgithub.com) are permitted; add the literal token npm to permit the npm source kind. Local installs are never "external" and are always allowed.
capabilities.auto_update	boolean	false	Whether installed third-party capabilities may auto-update. Off by default. Even when enabled, GSD re-prompts for explicit consent whenever a new version's executable surface set (hooks / command modules / MCP servers) differs from the installed one — the consent you gave was for a specific surface, not a blank cheque.

# Lock the machine down to local-only capability installs:
gsd config-set capabilities.strict_known_registries '[]'

# Allow only your org's GitHub + npm:
gsd config-set capabilities.strict_known_registries '["github.com", "npm"]'

Security note: strict_known_registries matching is host-based, not substring — a lookalike host like evilgithub.com is rejected even when github.com is allowed. integrity (sha512) pins only the top-level fetched artifact, not an npm package's transitive dependency tree; see the trust-model explanation for that boundary.

---

Feature Flags

Toggle optional capabilities via the features.* config namespace. Feature flags default to false (disabled) — enabling a flag opts into new behavior without affecting existing workflows.

Setting	Type	Default	Description
features.thinking_partner	boolean	false	Enable thinking partner analysis at workflow decision points
features.global_learnings	boolean	false	Enable cross-project learnings pipeline (auto-copy at phase completion, planner injection)
learnings.max_inject	number	10	Maximum number of cross-project learnings injected into each planner prompt. Lower values reduce prompt size; higher values provide broader historical context
intel.enabled	boolean	false	Enable queryable codebase intelligence system. When true, /gsd-map-codebase --query commands build and query a JSON index in .planning/intel/. Added in v1.34

Plan Review Settings

The plan_review.* namespace controls the plan drift guard, which verifies that symbols cited in generated plans (decorators, classes, functions, CLI flags) actually exist in your source code at review time. This catches hallucinated names before execution begins.

Setting	Type	Default	Description
plan_review.source_grounding	boolean	true	Enable the plan drift guard. When true (the default), plan review resolves every symbol reference cited in a PLAN.md against the live source tree. Plans that cite a non-existent function, class, decorator, or CLI flag produce a needs-acknowledgement notice before the plan is approved. The same key also gates the cross-artifact fact-drift pass, which reports when ROADMAP.md, PLAN.md, STATE.md and CONTEXT.md state the same fact in contradictory ways (advisory only — it never blocks convergence). Disable with false to skip both passes entirely. Toggle during setup (/gsd-new-project) or at any time via /gsd-settings.
plan_review.source_grounding_authority	enum	grep	Selects the resolver adapter used to verify symbol existence. Allowed values: grep (default — ripgrep/grep search of source files, works in any project without additional tooling), intel (query the .planning/intel/api-map.json index built by /gsd-map-codebase; requires intel.enabled: true), treesitter (reserved for future tree-sitter adapter), lsp (reserved for future LSP adapter), scip (reserved for future SCIP/LSIF adapter). Use intel when you have run /gsd-map-codebase and want the faster, pre-indexed lookup. All other values beyond grep and intel are reserved and have no effect in the current release.

MemPalace Settings

MemPalace is an opt-in, default-resilient memory capability. Every hook is onError: skip — a missing or unreachable MemPalace installation never halts or fails the loop. Enable with mempalace.enabled: true after installing MemPalace (pip install mempalace).

mempalace.enabled is the master gate: all five loop hooks (discuss, plan, execute-wave, verify, ship) and both curator contributions are gated on this key. When it is false (the default), nothing fires and the GSD loop is byte-for-byte unchanged. The remaining keys only refine behavior when mempalace.enabled is true; they are honored at runtime by the skills, curator, and fragments — they do not add independent hook gating.

Setting	Type	Default	Description
mempalace.enabled	boolean	false	Master gate for the MemPalace memory capability. When false (the default) every recall/capture hook is inactive and the loop is unchanged. All other mempalace.* keys are inert while this is false.
mempalace.memory_mode	enum: augment, kg_backend, replace	augment	How authoritative MemPalace is during recall/capture. augment (default — an additive recall layer alongside GSD's native graphs/learnings; native memory stays authoritative; lowest coupling). kg_backend (knowledge-graph queries resolve against MemPalace's temporal graph as the primary source, with .planning/graphs/ as fallback; non-KG drawer recall stays additive). replace (recall resolves through the palace as the source of truth, native artifacts as fallback). Every mode is onError:skip and default-resilient: an unreachable palace degrades to native memory and GSD keeps writing .planning/graphs/, so no memory is lost. Cross-mode migration of existing .planning/graphs/ into the palace is a separate, not-yet-implemented concern.
mempalace.wing	string	""	Palace wing name for this project. Empty (the default) derives the wing from project_code or the project directory name.
mempalace.recall_on_discuss	boolean	true	When mempalace.enabled is true: inject a wake-up + semantic-search recall fragment into the orchestrator at discuss:pre. Surfaces prior decisions, patterns, and surprises before the discussion starts.
mempalace.recall_on_plan	boolean	true	When mempalace.enabled is true: run the mempalace-recall skill at plan:pre to produce MEMORY-RECALL.md from prior decisions, patterns, and surprises relevant to the plan.
mempalace.capture_artifacts	boolean	true	When mempalace.enabled is true: file phase artifacts (CONTEXT.md, PLAN.md, SUMMARY.md) verbatim into MemPalace at their respective phase boundaries (discuss:post, plan:post, verify:post). Also captures confirmed bug→fix pairs at execute:wave:post.
mempalace.mirror_kg	boolean	true	When mempalace.enabled is true: mirror decisions and learnings into MemPalace's temporal knowledge graph (mempalace_kg_add with valid_from = phase date) alongside drawer capture.
mempalace.cross_project_tunnels	boolean	false	When mempalace.enabled is true: at ship:post, propose and create tunnels between this wing's rooms and semantically related wings in other projects (mempalace_find_tunnels, mempalace_create_tunnel).
mempalace.diary_journal	boolean	true	When mempalace.enabled is true: at ship:post, write a per-agent diary entry (mempalace_diary_write) summarising the session.
mempalace.auto_capture_hooks	boolean	false	Reserved — not yet implemented. Intended to install MemPalace's native Claude Code hooks (session-start, stop, precompact) for passive mid-session capture between loop points. The capability's hooks array is currently empty; no native hooks are installed by setting this key. This key is forward-declared for the future "Connected Capability" phase.

Memory modes in detail

Mode	KG-query source	Recall source	Coupling
augment (default)	GSD native + palace (additive)	GSD native + palace search	lowest
kg_backend	palace temporal KG primary, .planning/graphs/ fallback	GSD native + palace search	medium
replace	palace primary, native fallback	palace as source of truth, native fallback	highest

Mode is read at hook-render time; switching modes is a config change, not a reinstall. In every mode the palace is onError:skip and default-resilient — an unreachable palace degrades to native memory, and GSD keeps writing .planning/graphs/ so no memory is lost. Switching an established project to kg_backend/replace changes how new recall/capture resolve but does not backfill existing .planning/graphs/ into the palace (a separate, not-yet-implemented concern).

Example

# Enable MemPalace (augment is the default mode)
gsd-tools query config-set mempalace.enabled true

# Optional: route knowledge-graph recall through the palace's temporal KG (native as fallback)
# gsd-tools query config-set mempalace.memory_mode kg_backend

# Enable cross-project tunnel proposals at ship:post
gsd-tools query config-set mempalace.cross_project_tunnels true

Graphify Settings

Setting	Type	Default	Description
graphify.enabled	boolean	false	Enable the project knowledge graph. When true, /gsd-graphify builds and queries a graph in .planning/graphs/. Added in v1.36
graphify.build_timeout	number (seconds)	300	Maximum seconds allowed for a /gsd-graphify build run before it aborts. Added in v1.36
graphify.auto_update	boolean	false	Opt-in (issue #3347). When true (and graphify.enabled is also true), the bundled PostToolUse hook hooks/gsd-graphify-update.sh auto-rebuilds the project knowledge graph in a detached background process after git commit/merge/pull/rebase --continue/cherry-pick on the default branch (git.base_branch override, else main/master/trunk). Hook returns instantly; the rebuild updates .planning/graphs/{graph.json,graph.html,GRAPH_REPORT.md} and writes .planning/graphs/.last-build-status.json ({ts, status: "running"|"ok"|"failed", exit_code, duration_ms, head_at_build}). PID-locked, CI-aware ($CI env suppresses), bails silently if graphify is not on PATH. Default false so existing behaviour is unchanged after upgrade.
graphify.graph_path	string (path)	unset	Umbrella/multi-repo support (issue #1825). Overrides where /gsd-graphify query|status|diff read the knowledge graph from. Set to a path (relative to the project root, or absolute) pointing at a shared umbrella-level graph.json so a single curated cross-repo graph serves every sub-project without N drifting mirror copies. The diff snapshot (.last-build-snapshot.json) travels with the configured graph (same directory); the auto-update status sidecar stays project-local. Build stays project-scoped (.planning/graphs/) — build the umbrella graph in the umbrella project, then point sub-projects at it. When unset, behaviour is byte-identical to the historical .planning/graphs/graph.json. A clear, actionable error is returned when the configured file is missing.

Multi-developer setup

When multiple developers rebuild the graph in the same repository, graphify hook install (run once per clone) installs a git merge driver that union-merges concurrent graph.json writes, eliminating conflict markers. It also registers the post-commit rebuild hook, writes .gitattributes, and adds graphify merge-driver to .git/config. Solo projects may skip this step. Introduced upstream in graphify v0.7.0 alongside the built_at_commit freshness signal surfaced by /gsd-graphify status.

Commit-based staleness

/gsd-graphify status reports two orthogonal staleness signals:

• stale (mtime-based, 24-hour window) — when the graph file was last written. Useful when graphify isn't run automatically.
• commit_stale (commit-based, requires graphify v0.7+) — whether the graph was built against the current git HEAD. Trustworthy when present. Tri-state: true / false / null. null means the signal is unavailable (pre-v0.7 graph, no git, or unreachable commit) — fall back to the mtime flag.

A CI-built graph rebuilt minutes ago against an old checkout will read as fresh on mtime but commit_stale: true. Surface both when answering architecture questions.

Refactor-Trigger Settings

Setting	Type	Default	Description
refactor.trigger_enabled	boolean	false	Enable the complexity-triggered refactor hook. When true, an execute:post step evaluates the complexity of the files the phase touched and writes a scoped refactor proposal if a function crosses refactor.complexity_threshold or jumps past refactor.complexity_jump_delta. Opt-in; when false the hook never runs. Added in v1.10.0 (#1953)
refactor.complexity_threshold	number	15	Absolute per-function complexity above which a refactor proposal is surfaced. Semantics match ESLint's complexity: {max: N} — the trigger is strictly greater, so a score of exactly N does not trigger. Default 15 follows SonarSource's default; ESLint's own default is 20 and radon's rank C begins at 11. Raise it if proposals feel like noise. Added in v1.10.0
refactor.complexity_jump_delta	number	5	Complexity growth above which a refactor proposal is surfaced even when the absolute threshold is not reached. Measured against the function's anchor — the score recorded the last time the function was consciously dispositioned (refactor accept/refactor decline) — so it accumulates across phases and catches slow creep the absolute threshold would miss. Strictly greater, as with the threshold. Added in v1.10.0
refactor.trigger_strict	boolean	false	Record an untriaged refactor proposal as an open deviation entry in the broken-windows ledger, so it becomes a tracked task that must be resolved before ship. Off by default and deliberately so: a blocking complexity number is a metric an executor can satisfy by splitting one coherent function into two incoherent ones, so the entry clears on the proposal being dispositioned (gsd-tools refactor accept|decline), never on the score improving. Ship blocking is the broken-windows capability's existing ship:pre gate — enable it separately with workflow.windows_enforce. With broken-windows absent, strict mode still records the proposal locally and says so; it cannot block on its own. Enabling refactor.trigger_strict without also enabling workflow.windows_enforce (or with broken-windows not installed) surfaces a typed refactor_strict_not_enforcing warning on every triggering refactor evaluate, naming the exact remediation. Advisory mode (the default) surfaces the same proposal and tracks nothing. Added in v1.10.0

See ADR-1953 for the design rationale, including why the anchor moves only on disposition and never on the score improving.

Usage

# Enable a feature
gsd-tools query config-set features.global_learnings true

# Disable a feature
gsd-tools query config-set features.thinking_partner false

The features.* namespace is a dynamic key pattern — new feature flags can be added without modifying VALID_CONFIG_KEYS. Any key matching features.<name> is accepted by the config system.

Capability Overlay (installed third-party capabilities)

GSD supports an installed overlay of third-party capability manifests that are composed with the frozen first-party registry at runtime via loadRegistry({ includeInstalled: true }) (ADR-1244; see docs/reference/capability-manifest.md and docs/how-to/import-a-capability-from-a-url.md).

Install roots

Capability manifests (capability.json) are discovered from two scoped roots:

Scope	Path
Global	$GSD_HOME/.gsd/capabilities/<id>/capability.json
Project	<projectRoot>/.gsd/capabilities/<id>/capability.json

GSD_HOME defaults to your home directory (~) when unset. Both roots are scanned on every loadRegistry call; neither requires config changes to activate.

Composition and first-party-wins invariant

Installed overlay capabilities are merged via the same buildRegistry pipeline as first-party capabilities, so all derived views (bySkill, byAgent, byLoopPoint, configKeys) cover first-party and overlay entries identically. First-party always wins: an overlay entry is rejected at load time if its id, any owned skill or agent stem, or any federated config key collides with a first-party entry, or if its id uses a reserved prefix (gsd-, gsd-core-, anthropic-). Rejected entries emit a warning and are skipped; they never crash the load loop.

Load-time engines.gsd compatibility gate

Each overlay manifest may declare an engines.gsd semver range. At load time GSD evaluates this range against the running GSD version. An overlay that does not satisfy the range is skipped with a warning — it is never loaded and never crashes the loop. Manifests without an engines.gsd field are accepted unconditionally.

Gate-kind fail-open policy (#2009)

If a skipped or load-failed overlay capability (for example, one whose engines.gsd range is incompatible) declared a gate-kind loop hook, the loop resolver does not inject a gate at that hook point (fail OPEN): the loop proceeds. Instead it emits a loud warning — to stderr and in the loop render-hooks envelope's warnings array — naming the load-failure reason and the exact remediation, gsd capability remove <id>, so the operator is loudly told how to clear it. Skipped capabilities whose hooks are step or contribution kind skip open too, as before — the loop proceeds without them.

Overlay config federation

Config keys declared in an overlay capability's .config slice federate into the loadConfig return value via the same Federated Config channel as first-party capability keys. They appear as valid keys in config-schema.cjs (isValidConfigKey) and in the runtime config schema, so overlay capabilities can declare project-local config toggles without editing the central config schema.

See also: docs/reference/capability-manifest.md for the full capability.json schema, docs/how-to/import-a-capability-from-a-url.md for installation steps, and ADR-1244 for the design record.

Parallelization Settings

Setting	Type	Default	Description
parallelization	boolean	true	Shorthand for parallelization.enabled. Setting parallelization false disables parallel execution without changing other sub-keys
parallelization.enabled	boolean	true	Run independent plans simultaneously
parallelization.plan_level	boolean	true	Parallelize at plan level
parallelization.task_level	boolean	false	Parallelize tasks within a plan
parallelization.skip_checkpoints	boolean	true	Skip checkpoints during parallel execution
parallelization.max_concurrent_agents	number	3	Maximum simultaneous agents
parallelization.min_plans_for_parallel	number	2	Minimum plans to trigger parallel execution

Pre-commit hooks and parallel execution: When parallelization is enabled, executor agents commit with --no-verify to avoid build lock contention (e.g., cargo lock fights in Rust projects). The orchestrator validates hooks once after each wave completes. STATE.md writes are protected by file-level locking to prevent concurrent write corruption. If you need hooks to run per-commit, set parallelization.enabled: false.

---

STATE.md Frontmatter (Phase Lifecycle)

STATE.md carries YAML frontmatter that the status-line hook reads on every render. v1.40 adds four optional phase-lifecycle fields read by parseStateMd() and rendered by formatGsdState():

Field	Type	Purpose
active_phase	string (e.g. "4.5")	Phase number when an orchestrator command is in flight
next_action	string	Recommended next command when idle (discuss-phase / plan-phase / execute-phase / verify-phase)
next_phases	YAML flow array	Phases the next_action applies to (e.g. ["4.5"])
progress	block	Nested total_phases / completed_phases / percent for the milestone progress bar

All four fields are optional and additive — STATE.md files without them keep rendering exactly as in v1.38.x. See STATE.md schema for the full field reference, parser constraints, and rendering scenes.

---

Git Branching

Setting	Type	Default	Description
git.branching_strategy	enum	none	none, phase, or milestone
git.base_branch	string	main	The integration branch that phase/milestone branches are created from and merged back into. Override when your repo uses master or a release branch
git.create_tag	boolean	true	Create a git tag (v[X.Y]) on milestone completion. Set to false for projects with their own release flow
git.phase_branch_template	string	gsd/phase-{phase}-{slug}	Branch name template for phase strategy
git.milestone_branch_template	string	gsd/{milestone}-{slug}	Branch name template for milestone strategy
git.quick_branch_template	string or null	null	Optional branch name template for /gsd-quick tasks

Strategy Comparison

Strategy	Creates Branch	Scope	Merge Point	Best For
none	Never	N/A	N/A	Solo development, simple projects
phase	At execute-phase start	One phase	User merges after phase	Code review per phase, granular rollback
milestone	At first execute-phase	All phases in milestone	At complete-milestone	Release branches, PR per version

Template Variables

Variable	Available In	Example
{phase}	phase_branch_template	03 (zero-padded)
{slug}	Both templates	user-authentication (lowercase, hyphenated)
{milestone}	milestone_branch_template	v1.0
{num} / {quick}	quick_branch_template	260317-abc (quick task ID)

Example quick-task branching:

"git": {
  "quick_branch_template": "gsd/quick-{num}-{slug}"
}

Merge Options at Milestone Completion

Option	Git Command	Result
Squash merge (recommended)	git merge --squash	Single clean commit per branch
Merge with history	git merge --no-ff	Preserves all individual commits
Delete without merging	git branch -D	Discard branch work
Keep branches	(none)	Manual handling later

---

Gate Settings

Control confirmation prompts during workflows.

Setting	Type	Default	Description
gates.confirm_project	boolean	true	Confirm project details before finalizing
gates.confirm_phases	boolean	true	Confirm phase breakdown
gates.confirm_roadmap	boolean	true	Confirm roadmap before proceeding
gates.confirm_breakdown	boolean	true	Confirm task breakdown
gates.confirm_plan	boolean	true	Confirm each plan before execution
gates.execute_next_plan	boolean	true	Confirm before executing next plan
gates.issues_review	boolean	true	Review issues before creating fix plans
gates.confirm_transition	boolean	true	Confirm phase transition

---

Safety Settings

Setting	Type	Default	Description
safety.always_confirm_destructive	boolean	true	Confirm destructive operations (deletes, overwrites)
safety.always_confirm_external_services	boolean	true	Confirm external service interactions

---

Security Settings

Settings for the security enforcement feature (v1.31). All follow the absent = enabled pattern. These keys live under workflow.* in .planning/config.json — matching the shipped template and the runtime reads in workflows/plan-phase.md, workflows/execute-phase.md, workflows/secure-phase.md, and workflows/verify-work.md.

These keys live under workflow.* — that is where the workflows and installer write and read them. Setting them at the top level of config.json is silently ignored.

Setting	Type	Default	Description
workflow.security_enforcement	boolean	true	Enable threat-model-anchored security verification via /gsd-secure-phase. When false, security checks are skipped entirely
workflow.security_asvs_level	number (1-3)	1	OWASP ASVS verification level. Level 1 = opportunistic, Level 2 = standard, Level 3 = comprehensive
workflow.security_block_on	string	"high"	Minimum threat severity that blocks phase advancement. The auditor counts only open threats at or above this severity toward the blocking gate; none disables severity blocking. Options: "critical", "high", "medium", "low", "none"

Injection blocking (top-level security.*)

Distinct from the workflow.security_* keys above: the read-injection scanner reads a top-level security object (not workflow.security). Set it with gsd config-set security.injection_blocking true — it persists as a nested key (security.injection_blocking), never a flat dotted key.

Setting	Type	Default	Description
security.injection_blocking	boolean	false	Opt-in circuit-breaker for the read-injection scanner hook (gsd-read-injection-scanner.js, PostToolUse on Read/WebFetch/WebSearch). Default (false) is advisory: HIGH-confidence injection detections are logged but not blocked. When true, a HIGH detection emits decision: "block" to halt the agent's next step. Because the hook runs after the fetch, blocking does not retroactively redact content already in the transcript — it is a circuit-breaker, not a redactor. See the security model and ADR-1577.

---

Decision Coverage Gates (workflow.context_coverage_gate)

When discuss-phase writes implementation decisions into CONTEXT.md <decisions>, two gates ensure those decisions survive the trip into plans and shipped code (issue #2492).

Setting	Type	Default	Description
workflow.context_coverage_gate	boolean	true	Toggle for both decision-coverage gates. When false, both the plan-phase translation gate and the verify-phase validation gate skip silently.

What the gates do

Plan-phase translation gate (BLOCKING). Runs immediately after the existing requirements coverage gate, before plans are committed. For each trackable decision in <decisions>, it checks that the decision id (D-NN) or its text appears in at least one plan's must_haves, truths, or objective (front-matter), a ## must_haves/truths/tasks/objective heading, or an <objective>/<tasks>/<task>/<action>/<read_first>/<behavior>/<verify>/<acceptance_criteria>/<done> tag body. A miss surfaces the missing decision by id and refuses to mark the phase planned.

Verify-phase validation gate (NON-BLOCKING). Runs alongside the other verify steps. Searches every shipped artifact (PLAN.md, SUMMARY.md, files modified, recent commit subjects) for each trackable decision. Misses are written to VERIFICATION.md as a warning section but do not flip the overall verification status. The asymmetry is deliberate — by verify time the work is done, and a fuzzy substring miss should not fail an otherwise green phase.

How to write decisions the gates accept

The discuss-phase template already produces D-NN-numbered decisions. The gate is happiest when:

1. Every plan that implements a decision cites the id somewhere — must_haves.truths: ["D-12: bit offsets exposed"] or a D-12: mention in the plan body. Strict id match is the cheapest, deterministic path.
2. Soft phrase matching is a fallback for paraphrases — if a 6+-word slice of the decision text appears verbatim in a plan/summary, it counts.

Opt-outs

A decision is not subject to the gates when any of the following apply:

• It lives under the ### Claude's Discretion heading inside <decisions>.
• It is tagged [informational], [folded], or [deferred] in its bullet (e.g., - **D-08 [informational]:** Naming style for internal helpers).

Use these escape hatches when a decision genuinely doesn't need plan coverage — implementation discretion, future ideas captured for the record, or items already deferred to a later phase.

---

Review Settings

Configure per-CLI model selection for /gsd-review. When set, overrides the CLI's default model for that reviewer.

Setting	Type	Default	Description
review.models.gemini	string	(CLI default)	Model used when --gemini reviewer is invoked
review.models.claude	string	(CLI default)	Model used when --claude reviewer is invoked
review.models.codex	string	(CLI default)	Model used when --codex reviewer is invoked
review.models.opencode	string	(CLI default)	Model used when --opencode reviewer is invoked
review.models.agy	string	(CLI default)	Model used when the --antigravity / --agy reviewer is invoked. The key suffix is the CLI's own name (agy), not the lane slug — the lane declares which key it reads, so the two need not match
review.models.kimi-code	string	(CLI default)	Model used when the --kimi-code reviewer is invoked (injected into -m)
review.models.ollama	string	(server default)	Model name passed to Ollama when --ollama reviewer is invoked. If unset, the first available model reported by the server is used (e.g. llama3). Set to a specific tag: gsd config-set review.models.ollama codellama
review.models.lm_studio	string	(server default)	Model name passed to LM Studio when --lm-studio reviewer is invoked. If unset, the first available model reported by the server is used.
review.models.llama_cpp	string	(server default)	Model name passed to llama.cpp when --llama-cpp reviewer is invoked. If unset, the first model reported by /v1/models is used.
review.default_reviewers	string[] | null	(all detected reviewers)	Default reviewer subset for no-flag /gsd-review. Example: ["gemini","codex"]. May include configured review.reviewer_instances names. Explicit flags and --all override this setting.
review.max_prompt_tokens	number|null	null	Default maximum estimated tokens for the assembled review prompt. When set, the prompt is deterministically trimmed before being sent to each reviewer. Per-reviewer overrides via review.max_prompt_tokens_per_reviewer take precedence. null = no trim (current behavior).
review.max_prompt_tokens_per_reviewer	object	{}	Per-reviewer token budget overrides. Keys are reviewer slugs. Only lanes that declare a budget key accept one — today ollama, lm_studio and llama_cpp, the local model servers this exists for. Values override review.max_prompt_tokens for that reviewer. A per-lane value of 0 disables trimming for that lane specifically.
review.ollama_host	string	http://localhost:11434	Base URL of the Ollama server. Override when running Ollama on a non-default port or remote host: gsd config-set review.ollama_host http://192.168.1.10:11434
review.lm_studio_host	string	http://localhost:1234	Base URL of the LM Studio local server. Override when using a non-default port.
review.llama_cpp_host	string	http://localhost:8080	Base URL of the llama.cpp server (llama-server). Override when using a non-default port.

Prompt budgets for small-context reviewers

Local model servers (Ollama, llama.cpp, LM Studio) typically accept far fewer tokens than cloud APIs. Setting review.max_prompt_tokens_per_reviewer (or the global review.max_prompt_tokens fallback) triggers deterministic prompt trimming before the prompt is sent to that reviewer: CONTEXT is dropped first, then RESEARCH, then REQUIREMENTS; PROJECT.md is head-shrunk to the first 40 lines; PLANs are tail-truncated proportionally — instructions and roadmap are always preserved. When a reviewer is trimmed, a disclosure note is injected at the top of the prompt and trim metadata (budget, omitted sections, truncation percentage) is recorded in the REVIEWS.md frontmatter under trimmed_reviewers. If even the minimum review set (instructions + roadmap + plan stubs) exceeds the budget, the reviewer is skipped with a warning rather than sending a truncated prompt that would produce misleading feedback.

Example

{
  "review": {
    "models": {
      "gemini": "gemini-2.5-pro",
      "qwen": "qwen-max"
    }
  }
}

Falls back to each CLI's configured default when a key is absent. Added in v1.35.0 (#1849).

---

Manager Passthrough Flags

Configure per-step flags that /gsd-manager appends to each dispatched command. This allows customizing how the manager runs discuss, plan, and execute steps without manual flag entry.

Setting	Type	Default	Description
manager.flags.discuss	string	(none)	Flags appended to discuss-phase commands (e.g., "--auto")
manager.flags.plan	string	(none)	Flags appended to plan-phase commands (e.g., "--skip-research")
manager.flags.execute	string	(none)	Flags appended to execute-phase commands (e.g., "--cross-ai")

Example:

{
  "manager": {
    "flags": {
      "discuss": "--auto",
      "plan": "--skip-research",
      "execute": "--cross-ai"
    }
  }
}

Invalid flag tokens are sanitized and logged as warnings. Only recognized GSD flags are passed through.

All 33 shipped agents have explicit per-profile tier assignments in the catalog (sdk/shared/model-catalog.json). The table above shows a representative subset of the most-used agents. For agents not listed here, model_overrides accepts any shipped agent name. The authoritative profile data is derived from sdk/shared/model-catalog.json via gsd-core/bin/lib/model-catalog.cjs and sdk/src/model-catalog.ts.

Per-Agent Overrides

Override specific agents without changing the entire profile:

{
  "model_profile": "balanced",
  "model_overrides": {
    "gsd-executor": "opus",
    "gsd-planner": "haiku"
  }
}

Valid override values: opus, sonnet, haiku, inherit, or any fully-qualified model ID (e.g., "openai/o3", "google/gemini-2.5-pro").

model_overrides can be set in either .planning/config.json (per-project) or ~/.gsd/defaults.json (global). Per-project entries win on conflict and non-conflicting global entries are preserved, so you can tune a single agent's model in one repo without re-setting global defaults. This applies uniformly across Claude Code, Codex, OpenCode, Kilo, and the other supported runtimes. On Codex and OpenCode, the resolved model is embedded into each agent's static config at install time — spawn_agent and OpenCode's task interface do not accept an inline model parameter, so running gsd install <runtime> after editing model_overrides is required for the change to take effect. See issue #2256.

Per-Phase-Type Models (models) — added in v1.41

Express tuning at the phase level (planning, research, execution, verification) without learning the agent taxonomy. Added in #3023.

model_overrides is per-agent (precise but verbose; you have to know that gsd-codebase-mapper is research and gsd-doc-writer is execution). The models block lets you say "Opus for planning and execution, Sonnet for the rest" in two lines:

{
  "model_profile": "balanced",
  "models": {
    "planning": "opus",
    "discuss": "opus",
    "research": "sonnet",
    "execution": "opus",
    "verification": "sonnet",
    "completion": "sonnet"
  },
  "model_overrides": {
    "gsd-codebase-mapper": "haiku"
  }
}

5. Runtime default                       ← when nothing else applies

The five layers compose top-down: model_profile is the base tier, models[<phase_type>] overrides at the phase level, dynamic_routing (when enabled) escalates per-attempt on soft failure, model_overrides[<agent>] carves per-agent exceptions at the top, and the runtime default applies when nothing else does. In the example above, all five research agents resolve to sonnet except gsd-codebase-mapper, which the per-agent override pins to haiku. dynamic_routing is disabled by default — when off (enabled: false or block omitted), this section's behavior is unchanged from today.

Accepted values

models.<phase_type> accepts only tier aliases:

Value	Effect
"opus" / "sonnet" / "haiku"	Standard tier — runtime resolution maps to the active runtime's model for that tier
"inherit"	Agents in this phase follow the session model (same semantics as model_profile: "inherit")

If you need a fully-qualified model ID ("openai/gpt-5", "google/gemini-2.5-pro"), use model_overrides per agent instead. models.* is intentionally tier-only so the runtime-aware mapping stays correct on Codex / OpenCode / Antigravity CLI installs.

When to use which

You want	Use
One global tier strategy ("balanced everywhere")	model_profile
Coarse phase-level tuning ("Opus for planning")	models.<phase_type>
Per-agent precision ("force haiku on the codebase mapper")	model_overrides[<agent>]
Full model ID for a specific agent	model_overrides[<agent>]: "openai/gpt-5"

Mix freely — the precedence rule above resolves any overlap deterministically.

Validation

config-set rejects unknown phase-types:

$ gsd config-set models.deployment opus
Error: 'models.deployment' is not a valid config key

# Valid:
$ gsd config-set models.research sonnet

Direct edits to .planning/config.json are looser — the resolver simply ignores values it doesn't recognize and falls through to the profile tier — so a typo doesn't silently break tier resolution.

Dynamic Routing with Failure-Tier Escalation (dynamic_routing) — added in v1.41

Start cheap, escalate only when the agent fails the gate. Added in #3024.

dynamic_routing lets you pay for the cheap tier by default and only escalate to the more expensive tier when the orchestrator detects a soft failure (verification inconclusive, plan-check FLAG, etc.).

{
  "dynamic_routing": {
    "enabled": true,
    "tier_models": {
      "light":    "haiku",
      "standard": "sonnet",
      "heavy":    "opus"
    },
    "escalate_on_failure": true,
    "max_escalations": 1
  }
}

Agent default tiers

Each agent in MODEL_PROFILES declares one of three default tiers. The resolver picks tier_models[default_tier] for the first attempt.

Tier	Agents	Use case
light	gsd-codebase-mapper, gsd-doc-classifier, gsd-doc-verifier, gsd-integration-checker, gsd-intel-updater, gsd-nyquist-auditor, gsd-pattern-mapper, gsd-plan-checker, gsd-research-synthesizer, gsd-ui-auditor, gsd-ui-checker	Cheap/fast — pure mappers, scanners, low-stakes audits
standard	gsd-advisor-researcher, gsd-ai-researcher, gsd-code-fixer, gsd-code-reviewer, gsd-doc-synthesizer, gsd-doc-writer, gsd-domain-researcher, gsd-eval-auditor, gsd-executor, gsd-phase-researcher, gsd-project-researcher, gsd-ui-researcher, gsd-verifier	Default workhorse — research, writing, primary verification
heavy	gsd-assumptions-analyzer, gsd-debug-session-manager, gsd-debugger, gsd-eval-planner, gsd-framework-selector, gsd-planner, gsd-roadmapper, gsd-security-auditor, gsd-user-profiler	Deep reasoning — already at top, can't escalate further

Escalation flow

1. Orchestrator spawns agent → resolver returns tier_models[default_tier]
2. Soft failure?
   ├─ no → ✓ done (cheap path)
   └─ yes → orchestrator re-spawns at attempt+1
            → resolver returns tier_models[next_tier_up]
            → cap at max_escalations
3. Hard failure (exception/crash) → bypass escalation, surface immediately

If dynamic_routing.escalate_on_failure: false, soft failures do not advance the tier — every respawn keeps using tier_models[default_tier] regardless of the attempt counter. The kill-switch overrides the soft-failure branch above.

light → standard → heavy → heavy (heavy stays at heavy; can't go further).

Resolution precedence (highest → lowest)

1. model_overrides[<agent>] — full IDs accepted; targeted exception
2. dynamic_routing.tier_models[<tier>] (when enabled: true)
3. models[<phase_type>] — coarse phase-level (#3023)
4. model_profile — per-agent column from active profile
5. Runtime default

The dynamic_routing block is disabled by default — enabled: false (or omitting the block) preserves today's static resolution exactly.

Settings

Key	Type	Default	Description
dynamic_routing.enabled	boolean	false	Master switch. When true, the dynamic-routing resolver is used for tier selection.
dynamic_routing.tier_models.light	enum	(none)	Tier alias for the light tier. Typically haiku.
dynamic_routing.tier_models.standard	enum	(none)	Tier alias for standard. Typically sonnet.
dynamic_routing.tier_models.heavy	enum	(none)	Tier alias for heavy. Typically opus.
dynamic_routing.escalate_on_failure	boolean	true	When false, escalation is disabled (every attempt uses the default tier).
dynamic_routing.max_escalations	integer	1	Hard cap on retries per agent invocation. Prevents runaway loops. Also caps the provider ladder below.
dynamic_routing.provider_escalation	string[]	(none)	Ordered fallback model IDs tried when a run dies on a provider quota / rate limit. Added in v1.43 (#2296)

Provider escalation on quota-exceeded — added in v1.43

The tier ladder above escalates within one provider. That does not help when the provider itself is what ran out: a heavier tier on the same throttled account is still throttled. provider_escalation is a separate, opt-in ladder for exactly that case.

{
  "dynamic_routing": {
    "enabled": true,
    "tier_models": { "light": "haiku", "standard": "sonnet", "heavy": "opus" },
    "provider_escalation": ["gpt-5", "nvidia/llama-3.3"],
    "max_escalations": 2
  }
}

When an executor dies and gsd-tools agent classify-failure classifies the error body as quota-exceeded, execute-phase re-resolves the model from this list instead of waiting for a quota reset, logs the switch (sonnet → gpt-5), and honors any Retry-After the provider sent. The ladder is capped at min(max_escalations, provider_escalation.length); once spent, GSD reports every model it tried and falls back to the manual recovery prompt rather than silently retrying the last one.

• Opt-in. With no provider_escalation configured, quota failures keep today's manual wait-for-reset prompt exactly as before.
• Quota only. Other failure classes (classify-handoff-bug, unknown-failure) never consult this ladder — they keep the tier ladder.
• escalate_on_failure: false disables this ladder too.
• Entries are opaque model IDs passed to the runtime. Blank and non-string entries are dropped; the surviving order is preserved.

When to use which

You want	Use
One tier strategy across all agents	model_profile
Coarse phase-level tuning	models.<phase_type>
Per-agent precision (full IDs)	model_overrides
Cheap-by-default, escalate only on failure	dynamic_routing

dynamic_routing is structurally a cost lever: you pay Opus rates only for the hard cases that warrant Opus. Compose with model_overrides for per-agent exceptions (override always wins).

---

Effort Control (effort) — added in v1.42

Unified cross-provider effort knob. Added in #443.

Control the reasoning effort of agent invocations with a single config. The universal ladder is:

minimal < low < medium < high < xhigh < max

Effort is rendered per-runtime: output_config.effort for Claude (Claude Code subagent effort frontmatter / CLAUDE_CODE_EFFORT_LEVEL env), model_reasoning_effort for Codex (Responses API reasoning.effort).

Cross-provider clamping: max is Anthropic-only — it clamps to xhigh on Codex. minimal is Codex-only — it clamps to low on Claude.

The model-catalog's reasoning_effort per-tier hint is a legacy field kept for reference; effort is now config-driven.

Precedence (highest → lowest):

1. Invocation override (e.g. --effort flag on resolve-execution)
2. effort.agent_overrides[<agent-id>]
3. effort.routing_tier_defaults[<light|standard|heavy>]
4. effort.default
5. "high" (Anthropic Opus 4.8 universal default)

{
  "effort": {
    "default": "high",
    "routing_tier_defaults": {
      "light":    "low",
      "standard": "high",
      "heavy":    "xhigh"
    },
    "agent_overrides": {
      "gsd-planner": "max"
    }
  }
}

Settings

Key	Type	Default	Description
effort.default	enum	"high"	Global fallback effort level. Applies when no tier or agent override matches.
effort.routing_tier_defaults.light	enum	"low"	Effort for light-tier agents (fast mappers/scanners).
effort.routing_tier_defaults.standard	enum	"high"	Effort for standard-tier agents (workhorse agents).
effort.routing_tier_defaults.heavy	enum	"xhigh"	Effort for heavy-tier agents (deep reasoning).
effort.agent_overrides.<agent-id>	enum	(none)	Per-agent effort override. Beats tier defaults.

Valid effort values: minimal, low, medium, high, xhigh, max.

Where effort actually reaches — added in v1.8.0

Effort resolved from the cascade above reaches a runtime through one of two channels.

Install-time. The value is baked into the artifacts the installer generates — the effort: frontmatter key on a Claude subagent, model_reasoning_effort in a generated Codex .toml. This is fixed at install and changes only on reinstall or sync.

Invocation-time. When GSD spawns another CLI as a subprocess — the cross-AI reviewers in /gsd-review — the effort is appended to that CLI's own command line. Whether a host can receive effort this way is a declared capability (effortSurface, ADR-1239), not an assumption:

Reviewer CLI	Receives effort as
claude	--effort <level>
opencode	--variant <level>
codex	-c model_reasoning_effort=<level>

A host whose documentation states no reasoning setting is left untouched — no flag is guessed, and GSD never writes into your own CLI's config file to set one. Levels a given CLI does not accept are clamped to its nearest supported value (minimal → low for Claude, max → xhigh for Codex), so a cross-provider value never produces an invalid argument.

Before this, a review run inherited whatever effort happened to be configured in your personal CLI config, which is why the same project could produce very different review times on two machines. Setting effort.default (or an agent/tier override) now controls review runs too.

---

Fast Mode (fast_mode) — added in v1.42

Per-agent fast_mode propagation knob. Added in #443.

Control whether fast_mode is propagated to agent invocations. Only accepts real booleans — string "true" is rejected.

Note: fast_mode is only propagatable via API runtimes (api speed:"fast"). Claude Code has no per-subagent fast-mode mechanism — /fast is session-level only, so emitting a fast_mode frontmatter key on a Claude subagent is a silent no-op. fast_mode_supported in resolve-execution output tells you if the configured runtime supports it.

Precedence (highest → lowest):

1. Invocation override (e.g. --fast-mode flag on resolve-execution)
2. fast_mode.agent_overrides[<agent-id>] (boolean)
3. fast_mode.routing_tier_defaults[<light|standard|heavy>] (boolean)
4. fast_mode.enabled (boolean)
5. false

{
  "fast_mode": {
    "enabled": false,
    "routing_tier_defaults": {
      "light":    true,
      "standard": false,
      "heavy":    false
    },
    "agent_overrides": {}
  }
}

Settings

Key	Type	Default	Description
fast_mode.enabled	boolean	false	Global fast_mode flag. Only honored when no tier/agent override matches.
fast_mode.routing_tier_defaults.light	boolean	true	Fast mode for light-tier agents.
fast_mode.routing_tier_defaults.standard	boolean	false	Fast mode for standard-tier agents.
fast_mode.routing_tier_defaults.heavy	boolean	false	Fast mode for heavy-tier agents.
fast_mode.agent_overrides.<agent-id>	boolean	(none)	Per-agent fast_mode override.

---

Execution Query (resolve-execution)

Use node gsd-tools.cjs resolve-execution <agent-type> [--effort <level>] [--fast-mode <true|false>] [--attempt <n>] to get the full resolved execution context for an agent:

{
  "model":             "opus",
  "profile":           "balanced",
  "effort":            "xhigh",
  "effort_rendered":   "xhigh",
  "effort_param":      "output_config.effort",
  "effort_propagation": "frontmatter",
  "fast_mode":         false,
  "fast_mode_supported": false
}

effort_param tells you which runtime parameter to set. fast_mode_supported tells you whether the configured runtime supports per-agent fast_mode propagation.

---

Non-Claude Runtimes (Codex, OpenCode, Antigravity CLI, Kilo)

Codex CLI minimum supported version: 0.130.0 (issue #3562).

Codex CLI 0.130.0 (released 2026-05-08) removed extra-skills-roots discovery via openai/codex#21485. From this version forward, Codex CLI only scans ~/.codex/skills/<name>/SKILL.md, <project>/.codex/skills/, and registered plugin roots for invocable skills. GSD installs the $gsd-* surface as ~/.codex/skills/gsd-<name>/SKILL.md so commands resolve after a Codex restart. Earlier Codex CLI versions can show a duplicate listing (the legacy extra-roots scan plus the user-root copies) — restart Codex and either upgrade to ≥ 0.130.0 or accept the duplicates until you do.

When GSD is installed for a non-Claude runtime, the installer automatically sets resolve_model_ids: "omit" in ~/.gsd/defaults.json. This causes GSD to return an empty model parameter for all agents, so each agent uses whatever model the runtime is configured with. No additional setup is needed for the default case.

If you want different agents to use different models, use model_overrides with fully-qualified model IDs that your runtime recognizes:

{
  "resolve_model_ids": "omit",
  "model_overrides": {
    "gsd-planner": "o3",
    "gsd-executor": "o4-mini",
    "gsd-debugger": "o3",
    "gsd-codebase-mapper": "o4-mini"
  }
}

The intent is the same as the Claude profile tiers -- use a stronger model for planning and debugging (where reasoning quality matters most), and a cheaper model for execution and mapping (where the plan already contains the reasoning).

When to use which approach:

Scenario	Setting	Effect
Non-Claude runtime, single model	resolve_model_ids: "omit" (installer default)	All agents use the runtime's default model
Non-Claude runtime, tiered models	resolve_model_ids: "omit" + model_overrides	Named agents use specific models, others use runtime default
Claude Code with OpenRouter/local provider	model_profile: "inherit"	All agents follow the session model
Claude Code with OpenRouter, tiered	model_profile: "inherit" + model_overrides	Named agents use specific models, others inherit

resolve_model_ids values:

Value	Behavior	Use When
false (default)	Returns Claude aliases (opus, sonnet, haiku)	Claude Code with native Anthropic API
true	Maps aliases to full Claude model IDs (claude-opus-4-8)	Claude Code with API that requires full IDs
"omit"	Returns empty string (runtime picks its default)	Non-Claude runtimes (Codex, OpenCode, Antigravity CLI, Kilo)

The tier Field

node gsd-tools.cjs query resolve-model <agent> --pick tier returns the tier GSD resolved for that agent, independent of resolve_model_ids: opus | sonnet | haiku | fable | inherit | unknown. It is also emitted as a tier key in the command's full JSON output.

tier is computed above the resolve_model_ids: "omit" gate, so it stays meaningful exactly where model does not — every non-Claude install (blank under "omit") and any install where the runtime's tier map substitutes a name (e.g. gpt-5.6-luna for the haiku tier on Codex).

tier accounts for every step that can change which tier runs, including a model_policy preset — a preset resolves after the profile tier and can dispatch a different one, so model_policy: {provider: anthropic, budget: low} under a balanced profile reports haiku, not sonnet.

Honesty semantics: a model_overrides pin naming a known alias or a mappable full Claude id reports that alias; a pin to an unmappable raw model id reports unknown; a policy-resolved model that maps to no alias — including every non-Claude runtime, where the policy model is passed through verbatim — reports unknown rather than falling back to the profile tier; model_profile: inherit reports inherit; an agent with no catalog entry reports unknown. tier never guesses, so treat unknown and inherit as cannot tell, never as adequate.

One limit: a model_profile_overrides.<runtime>.<tier> entry that repoints a tier at another tier's model makes tier report the tier that was asked for, not the tier of the model that answers.

Runtime-Aware Profiles (#2517)

When runtime is set, profile tiers (opus/sonnet/haiku) resolve to runtime-native model IDs instead of Claude aliases. This lets a single shared .planning/config.json work cleanly across Claude and Codex.

resolve-model JSON output includes reasoning_effort when the runtime tier resolved for the agent (after phase-type overrides) defines a reasoning_effort. Runtime adapters may pass that value to child-agent launch calls that support it; runtimes without explicit support omit it.

Built-in tier maps:

Runtime	opus	sonnet	haiku	reasoning_effort
claude	claude-opus-4-8	claude-sonnet-5	claude-haiku-4-5	(not used)
codex	gpt-5.6-sol	gpt-5.6-terra	gpt-5.6-luna	xhigh / medium / medium
qwen	qwen3-max-2026-01-23	qwen3-coder-plus	qwen3-coder-next	(not used)
opencode	anthropic/claude-opus-4-8	anthropic/claude-sonnet-5	anthropic/claude-haiku-4-5	(not used)
copilot	claude-opus-4-8	claude-sonnet-5	claude-haiku-4-5	(not used)
hermes	anthropic/claude-opus-4-8	anthropic/claude-sonnet-5	anthropic/claude-haiku-4-5	(not used)
kilo	anthropic/claude-opus-4-8	anthropic/claude-sonnet-5	anthropic/claude-haiku-4-5	(not used)
pi	claude-opus-4-8	claude-sonnet-5	claude-haiku-4-5	(not used)
Group B (cline, cursor, windsurf (alias: devin-desktop), augment, trae, codebuddy, antigravity)	(no built-in default — your runtime handles model selection)

How these model IDs are sourced. The catalog (bin/shared/model-catalog.json) pins each runtime's tier defaults to that provider's current frontier IDs, and may intentionally carry forward-dated IDs ahead of a provider's public docs. To verify an ID is live before changing it, check the provider's own source/API — e.g. Codex: codex debug models or the OpenAI Codex models page; Qwen: Alibaba Model Studio model list. Only change an ID that the provider actually rejects — absence from documentation alone is not proof of invalidity.

Codex example — one config, tiered models, no large model_overrides block:

{
  "runtime": "codex",
  "model_profile": "balanced"
}

This resolves gsd-planner → gpt-5.6-sol (xhigh), gsd-executor → gpt-5.6-terra (medium), gsd-codebase-mapper → gpt-5.6-luna (medium). The Codex installer embeds model = "..." and model_reasoning_effort = "..." in each generated agent TOML.

Claude example — explicit opt-in resolves to full Claude IDs (no resolve_model_ids: true needed):

{
  "runtime": "claude",
  "model_profile": "quality"
}

Per-runtime overrides — replace one or more tier defaults:

{
  "runtime": "codex",
  "model_profile": "quality",
  "model_profile_overrides": {
    "codex": {
      "opus": "gpt-5-pro",
      "haiku": { "model": "gpt-5-nano", "reasoning_effort": "low" }
    }
  }
}

Precedence (highest to lowest):

1. model_overrides[<agent>] — explicit per-agent ID always wins.
2. Runtime-aware tier resolution (this section) — when runtime is set and profile is not inherit.
3. resolve_model_ids: "omit" — returns empty string when no runtime is set.
4. Claude-native default — model_profile tier as alias (current default).
5. inherit — propagates literal inherit for Task(model="inherit") semantics.

Backwards compatibility. Setups without runtime set see zero behavior change — every existing config continues to work identically. Codex installs that auto-set resolve_model_ids: "omit" continue to omit the model field unless the user opts in by setting runtime: "codex".

Unknown runtimes. If runtime is set to a value with no built-in tier map and no model_profile_overrides[<runtime>], GSD falls back to the Claude-alias safe default rather than emit a model ID the runtime cannot accept. To support a new runtime, populate model_profile_overrides.<runtime>.{opus,sonnet,haiku} with valid IDs.

Profile Philosophy

Profile	Philosophy	When to Use
quality	Opus for all decision-making, Sonnet for verification	Quota available, critical architecture work
balanced	Opus for planning only, Sonnet for everything else	Normal development (default)
budget	Sonnet for code-writing, Haiku for research/verification	High-volume work, less critical phases
inherit	All agents use current session model	Dynamic model switching, non-Anthropic providers (OpenRouter, local models)

---

Model Policy Presets (model_policy) — Added in v1.42

#49 — provider-neutral model policy config surface. Resolves before legacy model_profile_overrides.

model_policy provides a simpler, provider-neutral way to configure model tiers across runtimes. It is the preferred surface for non-Anthropic runtimes where model_profile_overrides would require manually knowing the right model IDs. Configure it via /gsd-settings → Section 8 (Model Policy).

Known provider preset

Choose a provider and budget level via the settings workflow; GSD writes the canonical model IDs for that provider/budget combination:

{
  "runtime": "codex",
  "model_policy": {
    "provider": "openai",
    "budget": "medium",
    "high":   "gpt-5.6-sol",
    "medium": "gpt-5.6-terra",
    "low":    "gpt-5.6-luna"
  }
}

Known providers: openai, anthropic, anthropic-fable, google, qwen. Budget levels: high, medium, low. Use anthropic to keep the Opus 4.8-backed Claude preset, or anthropic-fable to opt into Claude Fable 5 for high-budget top-tier routing. On the default claude runtime, policy-resolved model IDs are mapped to Claude Code agent aliases (for example claude-fable-5 → fable); an ID with no corresponding Claude alias emits a warning and falls back to the configured tier.

For advanced per-runtime control, runtime_tiers accepts explicit entries using the internal profile tier names (opus, sonnet, haiku):

{
  "runtime": "codex",
  "model_policy": {
    "provider": "openai",
    "runtime_tiers": {
      "codex": {
        "opus":   { "model": "gpt-5.6-sol",        "reasoning_effort": "high" },
        "sonnet": { "model": "gpt-5.6-terra",     "reasoning_effort": "medium" },
        "haiku":  { "model": "gpt-5.6-luna",      "reasoning_effort": "low" }
      }
    }
  }
}

Generic provider (escape hatch)

Use provider: "generic" (or "custom") for OpenRouter, LiteLLM, local gateways, or any runtime where you supply exact model IDs. GSD treats model IDs as opaque strings — no prefix inference, no provider-specific defaults:

{
  "runtime": "opencode",
  "model_policy": {
    "provider": "generic",
    "high":   "openrouter/anthropic/claude-opus-4-5",
    "medium": "openrouter/anthropic/claude-sonnet-4-5",
    "low":    "openrouter/anthropic/claude-haiku-4-5"
  }
}

Reasoning effort gating

reasoning_effort within a runtime_tiers entry is forwarded only to runtimes that declare support for it (currently: codex). Any runtime not on the allowlist receives the tier entry without the reasoning_effort field — it is silently stripped, never leaked.

Precedence

model_policy resolution sits above model_profile_overrides in the resolver:

1. model_overrides[<agent>] — per-agent explicit ID (highest)
2. model_policy.runtime_tiers[<runtime>][<tier>] — explicit runtime/tier entry
3. model_policy flat high/medium/low keys — for generic/custom provider
4. model_profile_overrides[<runtime>][<tier>] — legacy per-runtime override
5. Built-in runtime catalog default
6. model_profile tier alias

Backwards compatibility. Configs without model_policy are unaffected. Existing model_profile_overrides blocks continue to work exactly as before.

Environment Variables

Variable	Purpose
CLAUDE_CONFIG_DIR	Override default config directory (~/.claude/)
GEMINI_API_KEY	Detected by context monitor to switch hook event name
GSD_AUDIT	Set to 1 to enable the dispatch audit file (.planning/.gsd-trace.jsonl)
GSD_AUDIT_ARGS	Set to 1 to include command args in audit/error events (omitted by default)
GSD_PROJECT	Override project root for multi-project workspace support (v1.32)
GSD_SKIP_SCHEMA_CHECK	Skip schema drift detection during execute-phase (v1.31)
GSD_ALLOW_SYMLINKED_DEST	Set to 1 (or true) to permit install/update when CLAUDE_CONFIG_DIR (or any artifact-kind child like skills/, hooks/) is an intentional, user-owned symlink pointing outside the install root. v1.7.x write-confinement (ADR-1239 Phase B) refuses such layouts by default to prevent untrusted destSubpath traversal. Opt in only if you manage configHome via symlinked external dirs, multi-account config layouts (~/.claude-personal, ~/.claude-team), or dotfiles-managed configHome (nix-darwin, etc.). Two refusals remain load-bearing even with opt-in: path-traversal in destSubpath (../../etc-style), and a symlink whose resolved target equals the install root itself (would let the prune pass wipe it).
WSL_DISTRO_NAME	Detected by installer for WSL path handling

---

Global Defaults

Save settings as global defaults for future projects:

Location: ~/.gsd/defaults.json

When /gsd-new-project creates a new config.json, it reads global defaults and merges them as the starting configuration. Per-project settings always override globals.

---

Observability

The Command Routing Hub emits a structured DispatchEvent after every dispatch — including capability commands (graphify, intel, audit-uat, audit-open) since #1646. Default behaviour is silent on success and one structured JSON line to stderr on error.

Stderr error format

When a dispatch fails, one JSON line is emitted to stderr:

{ "kind": "HandlerFailure", "traceId": "...", "command": "plan", "timestamp": "...", "message": "..." }

The kind field matches one of the Hub's error variants: UnknownCommand, InvalidArgs, HandlerRefusal, or HandlerFailure. Args are omitted by default (privacy); see GSD_AUDIT_ARGS below.

Audit trail (opt-in)

Enable the append-only audit file to record every dispatch (success and error):

Via environment variable:

GSD_AUDIT=1 gsd plan

Via config (config.audit.enabled):

{
  "audit": {
    "enabled": true
  }
}

Audit file location: .planning/.gsd-trace.jsonl (gitignored)

Each line is a full DispatchEvent JSON object containing both traceId (a unique UUID v4 per dispatch) and parentTraceId (present when a caller passes req.parentTraceId into Hub.dispatch). A future init-composer (Phase 2) will wire parentTraceId automatically so that all child dispatches of a single top-level invocation share a common parent; until then, leaf dispatches emit parentTraceId: undefined. You can correlate child events to a parent by filtering the audit file on parentTraceId === <rootTraceId>. The file is append-only and never truncated; rotate or remove it manually when desired. parentTraceId must be a canonical UUID v4 (RFC 4122, format xxxxxxxx-xxxx-4xxx-[89ab]xxx-xxxxxxxxxxxx); values that do not match this format are silently dropped from the emitted event and will not appear in audit output.

Args redaction

By default, command args are omitted from all emitted events (both stderr errors and the audit file). To include args verbatim:

GSD_AUDIT_ARGS=1 GSD_AUDIT=1 gsd plan --tdd

GSD_AUDIT_ARGS applies to both the stderr error line and the audit file simultaneously.
