Tom Boucher 779f67cb11 fix(#4378): mint collision-free SEED-YYMMDD-xxx seed ids instead of a shared count (#4754)
* test(#4378): regression tests for collision-free seed ids

* fix(#4378): mint collision-free SEED-YYMMDD-xxx ids, not a shared count

plant-seed derived the next seed id from 'ls .planning/seeds/SEED-*.md | wc -l'.
.planning/seeds/ is shared but each worktree only sees what has merged, so two
workstreams planting before either merges computed the same id and git merged
both files silently.

The id is now the local date plus a 3-char random base36 suffix -- the shape
.planning/quick/ already uses -- computed from knowledge one worktree has alone,
with a same-day regen guard. deriveSeedIdentity learns the new canonical grammar
alongside legacy SEED-NNN (whose parsing never changes), the --enrich parser and
the filename-prefix fallback keep the full new-format id, and the docs that
state the filename shape move to it.

The prefix fallback previously truncated any non-pure-numeric id at
'SEED-<digits>' -- the same one-id-two-answers ambiguity the issue reports,
reproduced one level down.

* fix(#4378): harden seed id generation per adversarial review

- parse-idea: anchor the --enrich extractor to the flag and capture the
  complete id, uppercase-tolerant; a leftmost 'SEED-[0-9]+' truncated an
  uppercase or malformed suffix to its date and enriched an arbitrary
  same-day seed via head -1. Ambiguous and unmatched targets now fail
  closed instead.
- generate-seed-id: tolerate the expected SIGPIPE under pipefail, abort
  loudly when the suffix cannot be drawn (an empty suffix would collapse
  every seed's id to the bare date), and run the same-day regen guard as
  a find existence test (the 'ls <glob>' shape trips the #3409 drift
  guard and degenerates under a stray nullglob).
- deriveSeedIdentity: document the theoretical legacy/new grammar
  ambiguity (6-digit counter + 3-char base36 slug, no frontmatter).
- changeset: state the residual same-day collision bound instead of
  implying zero.

Emitted-Drift-Ack-Growth: plant-seed.md — the counting step became hardened date+random generation with explicit failure modes; growth is the failure handling, not duplicated logic

* fix(#4378): address standards and spec review findings

- tests: move the allow-test-rule marker to its suppression site (the
  file-header placement was inert per CONTRIBUTING site-scoping); add
  width-boundary coverage (5/7-digit dates, 2/4-char suffixes pin the
  documented branch behavior); add a writer-to-reader parity property
  that parses the mint widths out of the shipped workflow so the two
  grammar owners cannot drift; cover uppercase ids end-to-end in the
  reader.
- plant-seed.md: draw/retry restructured as one loop with a loud
  terminal failure; SEED_SUFX renamed SEED_SUFFIX; regen guard drops
  the redundant head -1; the ambiguity error no longer advises an
  impossible 'complete id' for duplicate legacy ids.
- commands.cts: refresh the cmdListSeeds comment still describing
  SEED-NNN as the only canonical form.
- changeset: drop the audit claim the spec axis showed to be an
  overstatement (audit's id display is filename-derived, pre-existing).
- remove a stray untracked artifact file swept into the tree.

* test(#4378): correct boundary expectations to the module's real branch behavior

The first matrix run on the boundary tests caught my hand-trace of the
regex branches, not a module defect: the slug regex's alternation
backtracks to the legacy branch whenever the canonical branch cannot
complete (so the slug is the remainder after the legacy numeric
prefix), and the 7-digit case fails the canonical branch at its 7th
digit before the dash. Pin the verified values.

* docs(#4378): backfill changeset PR number

* fix(#4378): audit seed identity uses the canonical grammar

Review of this PR found the audit surface publishing a fused filename
stem (SEED-081-region for SEED-081-region.md) where list-seeds reports
the canonical id -- one id, two answers across surfaces, the same
ambiguity class the issue files. scanSeeds now derives identity through
the SAME deriveSeedIdentity the list-seeds gate uses (frontmatter id,
then filename id-prefix, then stem), and audit-open acknowledge
resolves --seed-id by scanning for the derived identity, falling back
to the literal stem so callers scripted against pre-canonical output
keep working. Roll-in per the fix-inline rule: found during this PR's
review, same seed-identity seam.

RED probe: pre-fix audit published seed_id SEED-081-region-becomes /
slug 081-region-becomes for a legacy seeded file; post-fix SEED-081 /
region-becomes, matching list-seeds.

* test(#4378): probe timeout uses the class norm after windows-lane timeout

The windows conformance shard failed its bounded sh -c probes at the
local 5000ms bound (cold sh.exe spawn under shard load) while the
identical code passed this PR's two earlier windows waves. The probe
now uses PROBE_TIMEOUT_MS from the class-norm module instead of a local
override, per the helpers/timeouts.cjs convention.

GSD User Guide

A narrative companion guide to GSD Core — orient yourself here, then follow the links into the dedicated docs.

GSD Core's documentation is organised by Diataxis. Browse by goal: Tutorials · How-to guides · Reference · Explanation · Docs index


Table of Contents

For driving GSD directly from a GitHub / Linear / Jira issue, see the Issue-driven orchestration guide — a recipe that maps tracker issues onto the workspace → discuss → plan → execute → verify → review → ship loop using existing GSD primitives.


Slash-command form

GSD ships the same set of skills to every supported runtime, using the hyphen slash-form spelling:

  • Hyphen form — /gsd-command-name — used by Claude Code, Copilot, OpenCode, Kilo, Cursor, Windsurf, Augment, Antigravity, and Trae.

The installer writes this form into the command directory of each runtime you target.

Namespace routing primer (gsd-ns-*, v1.40+)

Architecture

GSD ships six namespace router bundles (gsd-ns-workflow, gsd-ns-project, gsd-ns-review, gsd-ns-context, gsd-ns-ideate, gsd-ns-manage). On runtimes with non-recursive skill loaders, the installer emits these 6 routers as the only top-level skill entries; the ~61 concrete skills are nested under each router at <router>/skills/<name>/SKILL.md. This reduces the eager skill-listing overhead to ≈6 entries instead of ≈67.

Each router's body contains a routing table. When the model receives a request, it reads the router, identifies the relevant sub-skill by name, then opens skills/<name>/SKILL.md via a file-path Read. The concrete skill is fully available — it is not invocable by bare name through the Skill tool's top-level listing, but is reachable through the router.

The nested layout applies only to runtimes with confirmed non-recursive skill loaders: Cline, Qwen, Hermes, Augment, Trae. Claude's loader is also non-recursive, but #924 reverted it flat because the Skill tool hard-errors on unknown names rather than re-routing via the router. Antigravity's loader is also non-recursive, but #1614 moved it flat because agy scans only skills/<name>/SKILL.md — nested sub-skills were unreachable. Other recursive or unconfirmed loaders (Cursor, Codex, Copilot, Windsurf, CodeBuddy, OpenCode, Kilo) retain the flat layout unchanged.

Namespace Router bundle Routes to
Phase pipeline gsd-ns-workflow discuss / plan / execute / verify / phase / progress
Project lifecycle gsd-ns-project milestones, audits, summary
Quality gates gsd-ns-review code review, debug, audit, security, eval, ui
Codebase intelligence gsd-ns-context map, graphify, docs, learnings
Exploration & capture gsd-ns-ideate explore, sketch, spike, spec, capture
Management gsd-ns-manage config, workspace, workstreams, thread, update, ship, inbox

Slash commands are unaffected

On runtimes that install a commands surface (commands/gsd), slash commands such as /gsd-plan-phase continue to work directly — the nesting applies only to the Skill tool's top-level listing, not to the commands directory.

Migration note (breaking change on nesting runtimes)

On the seven nesting runtimes listed above, upgrading to v1.40 changes skill invocation behaviour:

  • Before: each of the ~67 concrete gsd-<name> skills appeared at the top level and was invocable by bare name through the Skill tool.
  • After: only the 6 gsd-ns-* router bundles appear at the top level. Concrete skills are reachable via the router's routing table and a Read skills/<name>/SKILL.md call. Direct bare-name invocation of concrete skills through the Skill tool's listing no longer works.
  • Slash commands unchanged: /gsd-plan-phase, /gsd-discuss-phase, etc. still work directly where a commands surface is installed.
  • Upgrade prune: the installer's existing prune step removes the legacy top-level gsd-<concrete>/ skill directories on upgrade — no manual cleanup is needed.

Reading GSD's output

GSD marks its sections with Markdown, not with drawn borders. There are exactly three forms, and every workflow, checkpoint and report uses them:

You see It means
### GSD ► {STAGE NAME} A major workflow transition — planning, executing a wave, verifying, completing
### CHECKPOINT: {Type} GSD is waiting on you. The bolded **→ …** line at the bottom tells you what to type
--- A break between two sections — most often before the ▶ Next Up block at the end of a completion

Panels that used to be drawn with box characters are now a heading followed by their rows as ordinary lines. A checkpoint reads:

### CHECKPOINT: Verification Required

Progress: 5/8 tasks complete
Task: Responsive dashboard layout

How to verify:
  1. Visit: http://localhost:3000/dashboard

---

**→ YOUR ACTION: Type "approved" or describe issues**

Why there are no drawn borders

Earlier releases framed stage banners between two 53-character runs of ━, and checkpoints were a 62-column box drawn with ╔, ║ and ╚. Those runs are ordinary text to whatever renders GSD's output. In a pane narrower than the run, the rule wraps and the leftover glyphs land on a second line — so the border comes apart from the heading it was framing, and the output looks broken rather than merely narrow. Reported against the Codex desktop interface in #3028.

A Markdown heading and a thematic break carry the same structure without committing to a width, so they read correctly in a narrow pane and a wide one.

This is unconditional: every runtime gets the same output. The alternative — a capability flag that kept line-art for terminal-oriented runtimes — was weighed and rejected, because it leaves two output conventions to keep in sync forever for a gain that is aesthetic rather than structural. What a terminal loses is the drawn frame; what it keeps is the title, the hierarchy and the break, none of which depended on the frame. The reasoning is recorded in gsd-core/references/ui-brand.md § Why this is unconditional, not per-runtime. If you run GSD in a host where the heading form reads worse than the old boxes did, that is worth reporting — it is the evidence that would justify the flag.

Single-cell tokens are unaffected and unchanged: the status symbols (✓ ✗ ◆ ○ ⚠), the GSD ► prefix, and the ten-cell progress gauge (Progress: ████████░░ 80%) are not runs and do not wrap.

The convention is specified in gsd-core/references/ui-brand.md and enforced against all shipped content by tests/responsive-separators.test.cjs.


Project lifecycle overview

Validation Architecture (Nyquist Layer)

During plan-phase research, GSD maps automated test coverage to each phase requirement before any code is written. The researcher detects your existing test infrastructure, maps each requirement to a specific test command, and identifies any test scaffolding that must be created before implementation begins (Wave 0 tasks). The plan-checker enforces this as an 8th verification dimension: plans where tasks lack automated verify commands will not be approved.

Output: {phase}-VALIDATION.md — the feedback contract for the phase.

Disable: Set workflow.nyquist_validation: false in /gsd-settings for rapid prototyping phases where test infrastructure isn't the focus.

Retroactive Validation (/gsd-validate-phase)

For phases executed before Nyquist validation existed, or for existing codebases with only traditional test suites, retroactively audit and fill coverage gaps:

  /gsd-validate-phase N
         |
         +-- Detect state (VALIDATION.md exists? SUMMARY.md exists?)
         |
         +-- Discover: scan implementation, map requirements to tests
         |
         +-- Analyze gaps: which requirements lack automated verification?
         |
         +-- Present gap plan for approval
         |
         +-- Spawn auditor: generate tests, run, debug (max 3 attempts)
         |
         +-- Update VALIDATION.md
               |
               +-- COMPLIANT -> all requirements have automated checks
               +-- PARTIAL -> some gaps escalated to manual-only

The auditor never modifies implementation code — only test files and VALIDATION.md. If a test reveals an implementation bug, it's flagged as an escalation for you to address.

Assumptions Discussion Mode

By default, /gsd-discuss-phase asks open-ended questions about your implementation preferences. Assumptions mode inverts this: GSD reads your codebase first, surfaces structured assumptions about how it would build the phase, and asks only for corrections.

Enable: Set workflow.discuss_mode to 'assumptions' via /gsd-settings.

See docs/workflow-discuss-mode.md for the full discuss-mode reference.

Decision Coverage Gates

The discuss-phase captures implementation decisions in CONTEXT.md under a <decisions> block as numbered bullets (- **D-01:** …). Two gates ensure those decisions survive into plans and shipped code.

Plan-phase translation gate (blocking). After planning, GSD refuses to mark the phase planned until every trackable decision appears in at least one plan's scanned surfaces: front-matter must_haves/truths/objective, a ## must_haves/truths/tasks/objective heading, or an <objective>/<tasks>/<task>/<action>/<read_first>/<behavior>/<verify>/<acceptance_criteria>/<done> tag body.

Verify-phase validation gate (non-blocking). During verification, GSD searches plans, SUMMARY.md, modified files, and recent commit messages for each trackable decision. Misses are logged to VERIFICATION.md as a warning section; verification status is unchanged.

Opting a decision out. Move it under the ### Claude's Discretion heading inside <decisions>, or tag it: - **D-08 [informational]:** …, - **D-09 [folded]:** …, - **D-10 [deferred]:** ….

Disabling the gates. Set workflow.context_coverage_gate: false in .planning/config.json (or via /gsd-settings). Default is true.

               └── FAIL -> Issues logged for /gsd-verify-work

Isolated-run Recovery (fail-safe)

When a worktree-isolated run is rejected — the user declines to merge it, or the run over-reached the requested scope, or the orchestrator surfaces recovery guidance for a blocked plan — GSD halts safely and offers two options: (a) re-attempt in a fresh, narrowly-scoped worktree, or (b) inspect or discard the rejected worktree without merging. GSD never defaults recovery to editing the primary checkout (main). Any path that edits the primary checkout requires explicit, clearly-labeled confirmation from the user first. This behavior is unconditional and applies to both /gsd-execute-phase (worktree executor waves) and /gsd-quick (quick-mode isolated runs).


UI Design Contract

AI-generated frontends are visually inconsistent not because Claude Code is bad at UI but because no design contract existed before execution. /gsd-ui-phase locks the design contract before planning; /gsd-ui-review audits the result after execution.

For the full workflow, configuration, shadcn initialisation, and the registry safety gate, see Design a UI phase.

Quick reference:

Command Description
/gsd-ui-phase [N] Generate UI-SPEC.md design contract for a frontend phase
/gsd-ui-review [N] Retroactive 6-pillar visual audit of implemented UI
Setting Default Description
workflow.ui_phase true Generate UI design contracts for frontend phases
workflow.ui_safety_gate true plan-phase prompts to run /gsd-ui-phase for frontend phases

Spiking & Sketching

Use /gsd-spike to validate technical feasibility before planning, and /gsd-sketch to explore visual direction before designing. Both store artifacts in .planning/ and integrate with the project-skills system via their wrap-up companions.

For the full workflow and flow diagram, see Spike and sketch.

Typical flow:

/gsd-spike "SSE vs WebSocket"     # Validate the approach
/gsd-spike --wrap-up              # Package learnings

/gsd-sketch "real-time feed UI"   # Explore the design
/gsd-sketch --wrap-up             # Package decisions

/gsd-discuss-phase N              # Lock in preferences (now informed by spike + sketch)
/gsd-plan-phase N                 # Plan with confidence

Backlog & Threads

Backlog Parking Lot

Ideas that aren't ready for active planning go into the backlog using 999.x numbering, keeping them outside the active phase sequence.

/gsd-capture --backlog "GraphQL API layer"     # Creates 999.1-graphql-api-layer/
/gsd-capture --backlog "Mobile responsive"     # Creates 999.2-mobile-responsive/

Backlog items get full phase directories, so you can use /gsd-discuss-phase 999.1 to explore an idea further or /gsd-plan-phase 999.1 when it's ready. Backlog directories (and the 0-* pre-milestone directory some projects carry) are excluded from /gsd-progress, /gsd-stats, and phase listings for the current milestone — they stay out of the active phase sequence for counting purposes too, not just for planning.

Review and promote with /gsd-review-backlog — it shows all backlog items and lets you promote (move to active sequence), keep (leave in backlog), or remove (delete).

Seeds

Seeds are forward-looking ideas with trigger conditions. Unlike backlog items, seeds surface automatically when the right milestone arrives.

/gsd-capture --seed "Add real-time collab when WebSocket infra is in place"

/gsd-new-milestone scans all seeds and presents matches. Storage: .planning/seeds/SEED-YYMMDD-xxx-slug.md

Once you've parked a few, audit them on demand instead of waiting for the next milestone to surface them:

/gsd-capture --list-seeds            # Review every parked seed
/gsd-capture --list-seeds dormant    # Narrow to one status

This is read-only — it renders an audit table (ID, status, scope, trigger, title) and a per-status summary, and never modifies a seed. Filter by dormant, active, or triggered when you only want to see seeds in one state.

Persistent Context Threads

Threads are lightweight cross-session knowledge stores for work that spans multiple sessions but doesn't belong to any specific phase.

/gsd-thread                              # List all threads
/gsd-thread fix-deploy-key-auth          # Resume existing thread
/gsd-thread "Investigate TCP timeout"    # Create new thread

Threads can be promoted to phases (/gsd-phase) or backlog items (/gsd-capture --backlog) when they mature. Storage: .planning/threads/{slug}.md


Workstreams & Workspaces

Workstreams and workspaces both provide isolation, but at different levels.

Workstreams share the same codebase and git history but isolate planning artifacts — lighter weight, good for working on multiple milestone areas concurrently. See Work in parallel with workstreams.

Workspaces create separate repo worktrees with their own .planning/ — heavier, for feature-branch or multi-repo isolation. See Isolate work with workspaces.

Command Purpose
/gsd-workstreams create <name> Create a new workstream with isolated planning state
/gsd-workstreams switch <name> Switch active context to a different workstream
/gsd-workstreams list Show all workstreams and which is active
/gsd-workstreams complete <name> Mark a workstream as done and archive its state
# Workspace example — feature branch isolation
/gsd-workspace --new --name feature-b --repos .
cd ~/gsd-workspaces/feature-b
/gsd-new-project

/gsd-workspace --list
/gsd-workspace --remove feature-b

Security

Defense-in-Depth (v1.27)

GSD generates markdown files that become LLM system prompts. This means any user-controlled text flowing into planning artifacts is a potential indirect prompt injection vector. v1.27 introduced centralised security hardening:

Path Traversal Prevention: All user-supplied file paths (--text-file, --prd) are validated to resolve within the project directory. macOS /var → /private/var symlink resolution is handled.

Prompt Injection Detection: The security.cjs module scans for known injection patterns in user-supplied text before it enters planning artifacts.

Runtime Hooks:

  • gsd-prompt-guard.js — Scans Write/Edit calls to .planning/ for injection patterns (always active, advisory-only)
  • gsd-workflow-guard.js — Warns on file edits outside GSD workflow context (opt-in via hooks.workflow_guard)
  • gsd-write-guard.js — Hard-blocks a whole-file Write that catastrophically shrinks a curated .planning/ artifact (ROADMAP.md, milestone roadmaps, STATE.md) below 40% of its on-disk line count; files under 40 lines are exempt. The check is stateless per Write, comparing each payload against the file's current on-disk size — a single-shot collapse (the #973 shape) is blocked, but a sequence of individually-tolerated shrinks that erodes the file across several Writes is not detected. For a legitimate milestone reset or large deletion, bypass once with the single-use sentinel — write the target's path into .planning/.gsd-allow-shrink (fresh within 15 minutes; consumed by the allowed write) — or, interactively, with GSD_ALLOW_PLANNING_SHRINK=1 in the runtime's environment. Scope the guarantee accordingly: this stops accidental and single-shot collapse, and is not a defense against a determined agent — the sentinel is a plain file, so anything with shell access can arm one; what it buys is that the bypass becomes a deliberate, path-bound, single-use and auditable action rather than a sentence to reason past (always active, blocking; #2255, fix 3 of #973)
  • gsd-secret-read-guard.js — Hard-blocks reads of secret files — .env, .env.<suffix> and .secrets, matched case-insensitively (.ENV, .Secrets) — through Read (file_path), Grep (an explicit path, or a glob that selects them, judged per brace alternative) and Bash (operands, input redirects, $( ) / backtick / <( ) bodies, and git show <ref>:<path> shapes). A shell interpreter (bash/sh/zsh/dash/ksh) has its script scanned however it arrives — -c '…', a <( ) file operand, a heredoc / here-string, or a pipe from a knowable echo/printf source (echo cat .env | bash) — as do eval's joined operands, a source/. process-substitution operand, and find … | xargs cat pipelines (upstream literal names become the sub-command's read operands). A name is exempt when its final extension is example, sample, template or dist, so .env.example and equally .env.local.example / .env.production.sample stay readable (they are the templates GSD's own phase prompt reads). Stated cost: the exempt set is that unbounded family, not four fixed names — a real secret is not protected if it is named to end in one of those four extensions. Order matters, and only the last segment counts: .env.example.local is a secret and stays blocked. Trailing dots and spaces are stripped before the name is judged, because Windows resolves .env., .env and .secrets. to the protected file itself. Existence checks ([ -f .env ], ls .env*, test, stat, rm, touch, echo, …) pass. Not covered, by construction: $VAR indirection (bash -c "$CMD"), shell globs (cat .e*), interpreter one-liners, a piped script from a non-echo/printf source (cat gen.sh | bash, curl … | sh), reads inside scripts the agent runs, and a Grep glob: '*' reaching a .env that is not gitignored — none are statically resolvable by a hook. This replaces the Read(.env) / Read(.env.*) / Read(.secrets) permission deny rules the installer used to write: on Claude Code ≥ 2.1.259 any Read() deny rule makes every cd DIR && grep … compound prompt for approval even in auto mode, while a hook denial is not a permission rule and applies in auto and bypassPermissions alike (always active, blocking; #4221)

CI Scanner: prompt-injection-scan.security.test.cjs scans all agent, workflow, and command files for embedded injection vectors.


Package Legitimacy Gate (v1.42.1)

AI coding tools hallucinate package names. Attackers pre-register those names on npm, PyPI, and crates.io with malicious post-install scripts — a technique called slopsquatting. v1.42.1 adds a three-layer gate that stops this before it reaches your shell.

In RESEARCH.md — every phase that recommends external packages includes a ## Package Legitimacy Audit table:

## Package Legitimacy Audit

| Package | Registry | Age | Downloads | Source Repo | Verdict | Disposition |
|---------|----------|-----|-----------|-------------|---------|-------------|
| express | npm | 13 yrs | 100M+/wk | github.com/expressjs/express | [OK] | Approved |
| some-new-util | npm | 3 days | 47 | none | [SLOP] | REMOVED |
| api-bridge | npm | 6 mo | 1.2k/wk | github.com/user/api-bridge | [SUS] | Flagged |

[SLOP] packages are removed from RESEARCH.md entirely and never reach the planner.

In PLAN.md — [SUS] or [ASSUMED] packages trigger a checkpoint:human-verify task before the install.

During execution — if an install fails, the executor surfaces a checkpoint and stops rather than silently trying an alternative.

Legitimacy verdicts:

Verdict Meaning GSD action
[OK] Passes all legitimacy checks Proceeds — no checkpoint added
[SUS] Suspicious signals Flagged; planner adds checkpoint:human-verify
[SLOP] High-confidence hallucination Removed from RESEARCH.md; never reaches planner

Verdicts are computed from live registry APIs (npm, PyPI, crates.io) — there is no separate tool to install. slopcheck is an optional escalate-only adapter (it can raise a verdict but never lower one); no shipped configuration wires it, and its absence does not change the gate's behavior.


Code Review Workflow

After executing a phase, run a structured code review before UAT. See Set up cross-AI review for the full workflow.

/gsd-code-review 3               # Review all changed files in phase 3
/gsd-code-review 3 --depth=deep  # Deep cross-file review
/gsd-code-review 3 --fix         # Fix Critical + Warning findings atomically
/gsd-code-review 3 --fix --auto  # Fix and re-review until clean (max 3 iterations)
/gsd-audit-fix                   # Audit + classify + fix (medium+ severity, max 5)

The review step slots in after execution and before UAT:

/gsd-execute-phase N  ->  /gsd-code-review N  ->  /gsd-code-review N --fix  ->  /gsd-verify-work N

Optional external source-review lanes (#4209): /gsd-code-review accepts the same reviewer-lane flags as /gsd-review (run gsd_run review-lane flags to list the flags your installation's roster declares, e.g. --codex, --agy). Adding one asks that lane to independently review the same file scope alongside the internal gsd-code-reviewer agent; its findings are unverified corroborating evidence that gsd-code-reviewer re-checks against the actual source before writing anything to REVIEW.md — there is still exactly one REVIEW.md. No reviewer-lane flag is the default and reviews with only the internal agent, unchanged from before #4209. This is separate from /gsd-review, which reviews PLAN.md files before execution, not source code — see Set up cross-AI review.

/gsd-code-review 3 --codex       # Corroborate the internal review with the codex reviewer lane

Coverage-Aware UAT Routing

Historically, /gsd-verify-work turned every ## Accomplishments bullet in a SUMMARY into a manual checkpoint — even deliverables already covered one-to-one by a passing unit test. With a green test suite you were still asked to re-confirm things the tests had already proven, every phase.

GSD now lets the executor record, at authoring time, how each deliverable was verified. When a SUMMARY.md carries a coverage: frontmatter block (see the coverage: block reference), /gsd-verify-work routes deterministically:

  • Auto-passed — a deliverable marked human_judgment: false whose verification list is non-empty and entirely pass is recorded as passed (source: automated) and never prompted.
  • Presented — everything else is shown to you for sign-off: anything flagged human_judgment: true (visual adequacy, multi-device behaviour, subjective quality), anything with no verification, anything not fully passing, and any malformed entry.

The asymmetry is deliberate. The worst outcome is auto-passing something broken that UAT existed to catch, so auto-pass is the narrow, fully-proven case and uncertainty always routes back to you. Flipping the flag alone cannot skip a prompt — a passing test reference is also required. SUMMARYs without a coverage: block behave exactly as before (prose-based checkpoints), so nothing changes for existing or un-migrated phases.


Command And Configuration Reference

  • Command Reference: see docs/COMMANDS.md for every stable command's flags, subcommands, and examples.
  • Configuration Reference: see docs/CONFIGURATION.md for the full config.json schema, model-profile table, git branching strategies, and security settings.
  • Discuss Mode: see docs/workflow-discuss-mode.md for interview vs assumptions mode.

Graphify capability gate (tri-state, v1.43+)

Graphify commands (graphify status, graphify build, graphify query, graphify diff) now respect the full tri-state capability gate:

  1. Installed — the gsd-graphify-* skills are present in the active install profile.
  2. Surfaced — those skills appear on the current runtime surface (e.g., in ~/.claude/commands/gsd/).
  3. Config-enabled — graphify.enabled: true is set in .planning/config.json.

All three conditions must be true. Setting graphify.enabled: true alone is no longer sufficient if graphify has not been installed and surfaced. If graphify commands return { disabled: true } after upgrading, verify that the install profile includes graphify skills (gsd-tools capability state) and re-run the installer to surface them.

Intel capability gate (tri-state, v1.44+)

Intel commands (intel status, intel query, intel diff, intel snapshot, intel validate, intel api-surface) now respect the full tri-state capability gate (same resolver as graphify above):

  1. Installed — the intel capability is present in the active install profile (intel has no skill files, so this is vacuously true for all profiles).
  2. Surfaced — the intel capability is on the current runtime surface (vacuously true for all surfaces since intel registers no skill stems).
  3. Config-enabled — intel.enabled: true is set in .planning/config.json.

For intel, conditions 1 and 2 are always satisfied (intel has no skill files). The effective gate is intel.enabled in config — the same behaviour as before, but now enforced through the shared isCapabilityActive('intel', cwd) resolver rather than a direct config read. This means intel honours the full capability-state pipeline, including any future install-profile or surface restrictions. If intel commands return { disabled: true }, ensure intel.enabled: true is set in .planning/config.json and verify gsd-tools capability state shows intel as active.

Compact content mode (workflow.compact_content, v4139+)

GSD's own workflow instructions, planning-artifact templates, and (for non-Claude runtimes) agent personas are prose — and a large eagerly-loaded instruction body is context the model spends on GSD's own orchestration rather than on your code. workflow.compact_content (default false) opts a project into token-minimized variants of that content wherever one has been authored, without changing what GSD actually does.

Why turn it on: finite attention, not price. The point of this key is not a cheaper invocation — with prompt caching, the per-request cost of re-sending a large instruction file is already small. The point is what a large always-loaded instruction body costs in attention: every byte of GSD's own prose sitting in context is a byte not spent reasoning about your codebase. That cost is paid whether or not the tokens were cheap to transport. Turn it on when you're running long sessions, working in a large codebase that already competes for context, or on a runtime with a small context window; leave it off (the default) if you'd rather have every elaboration and worked example available up front, or you're evaluating GSD for the first time and want full detail while you learn how it thinks.

What actually changes. Nothing is compressed at runtime. Every compact variant is a hand-authored, reviewed file sitting beside its canonical sibling — the key only chooses which one GSD reads. Guardrails, output-format contracts, few-shot examples, and security language are never shortened or dropped in a compact variant; only rarely-needed elaboration and restatement are. With the key off, behavior is unchanged from before this feature existed.

How to turn it on: answer "Yes" to the Compact Content question during /gsd-new-project, or run /gsd-settings (or /gsd-config with no flag) on an existing project and toggle Compact Content. See docs/CONFIGURATION.md for the mechanics and ADR-4139 for the full design rationale.


Usage Examples

New Project (Full Cycle)

claude --dangerously-skip-permissions
/gsd-new-project            # Answer questions, configure, approve roadmap
/clear
/gsd-discuss-phase 1        # Lock in your preferences
/gsd-ui-phase 1             # Design contract (frontend phases)
/gsd-plan-phase 1           # Research + plan + verify
/gsd-execute-phase 1        # Parallel execution
/gsd-verify-work 1          # Manual UAT
/gsd-ship 1                 # Create PR from verified work
/gsd-ui-review 1            # Visual audit (frontend phases)
/clear
/gsd-progress --next                   # Auto-detect and run next step
...
/gsd-audit-milestone        # Check everything shipped
/gsd-complete-milestone     # Archive, tag, done
/gsd-pause-work --report         # Generate session summary

Caution

The permissions flag is optional. It skips per-file confirmation while GSD's sub-agents read and write files. Use it only in low-stakes or throwaway contexts. To keep confirmations enabled, start with claude instead. For real work, read the security model first.

New Project from Existing Document

/gsd-new-project --auto @prd.md   # Auto-runs research/requirements/roadmap from your doc
/clear
/gsd-discuss-phase 1               # Normal flow from here

Existing Codebase

/gsd-onboard                # Safely map, ingest docs, and initialize planning
# Follow the printed top-level handoff commands, then rerun /gsd-onboard
# (normal phase workflow from here)

/gsd-onboard routes through /gsd-map-codebase, /gsd-ingest-docs, and /gsd-new-project without nesting interactive workflows or overwriting existing planning files silently.

Post-execute drift detection (#2003). After every /gsd-execute-phase, GSD checks whether the phase introduced enough structural change to make .planning/codebase/STRUCTURE.md stale. Flip the behavior with:

/gsd-settings workflow.drift_action auto-remap       # remap automatically
/gsd-settings workflow.drift_threshold 5             # tune sensitivity

Plan Drift Guard

Default-on. The plan drift guard (plan_review.source_grounding: true) runs during plan review and verifies that every symbol your plans cite — decorators, classes, functions, CLI flags — actually exists in your source tree at review time. This catches hallucinated names before any execution agent runs.

Two axes, one switch. The same guard also runs a cross-artifact fact-drift pass: when ROADMAP.md, PLAN.md, STATE.md and CONTEXT.md state the same fact in contradictory ways — a phase marked complete in one and in progress in the other, a success criterion the plan restates with a different outcome, a term used against its CONTEXT.md definition — you get an advisory finding in REVIEWS.md naming both locations and which one is authoritative. It keys on contradicting knowledge, not on similar-looking text, so a plan that simply restates a criterion in its own words is not flagged. The findings never block convergence.

What it catches:

  • Functions referenced in a PLAN.md step that don't exist in source
  • Class or decorator names that were renamed or removed since the plan was written
  • CLI flags documented in a plan that are not defined in the argument parser
  • Module paths cited in implementation steps that resolve to no files

Needs-acknowledgement behavior. When the guard finds a missing symbol, it emits a needs-acknowledgement notice in the plan review output rather than hard-blocking. You can acknowledge and proceed (the symbol may be intentionally new) or request a plan revision. The guard does not auto-reject plans — it surfaces signal for human decision.

Works without intel. By default the guard uses grep/ripgrep to search source files — no pre-indexing required. If you have run /gsd-map-codebase with intel.enabled: true, set plan_review.source_grounding_authority: intel to use the faster pre-built api-map.json index instead.

# Enable/disable (default: on)
/gsd-settings plan_review.source_grounding true
/gsd-settings plan_review.source_grounding false

# Switch resolver authority
/gsd-settings plan_review.source_grounding_authority grep   # live grep (default)
/gsd-settings plan_review.source_grounding_authority intel  # pre-indexed api-map.json

Toggle at project setup (/gsd-new-project asks during workflow preferences) or any time via /gsd-settings (Planning section → Drift Guard).

Troubleshooting

For a comprehensive troubleshooting guide, see Recover and troubleshoot. The most common issues are summarised below.

Programmatic CLI (gsd-tools query vs gsd-tools.cjs)

For automation, prefer gsd-tools query with a registered subcommand (see CLI-TOOLS.md — SDK and programmatic access and QUERY-HANDLERS.md). The legacy node $HOME/.claude/gsd-core/bin/gsd-tools.cjs CLI remains supported.

STATE.md Out of Sync

node "$HOME/.claude/gsd-core/bin/gsd-tools.cjs" state validate          # Detect drift
node "$HOME/.claude/gsd-core/bin/gsd-tools.cjs" state sync --verify     # Preview changes
node "$HOME/.claude/gsd-core/bin/gsd-tools.cjs" state sync              # Reconstruct STATE.md

state validate's report carries a scope field alongside valid — valid:true means no drift was found, but scope says whether the check could actually run at all (a phase that could not be resolved, or an unreadable frontmatter/phases directory, reports valid:true too, because there was nothing to flag). See Interpret state validate results before treating a passing state validate as "clean."

A Command Looks Frozen After "Spawning..."

GSD subagents run in a separate context window — their work is invisible to the parent session while in progress. Do not interrupt the session. Wait for the result; research and planning agents routinely take 1–5 minutes.

Context Degradation During Long Sessions

Clear your context window between major commands: /clear in Claude Code. GSD is designed around fresh contexts — every subagent gets a clean 200K window. Use /gsd-resume-work or /gsd-progress to restore state after clearing.

Plans Seem Wrong or Misaligned

Run /gsd-discuss-phase [N] before planning. Most plan quality issues come from Claude making assumptions that CONTEXT.md would have prevented.

Execution Fails or Produces Stubs

Check that the plan was not too ambitious. Plans should have 2–3 tasks maximum. Re-plan with smaller scope.

Lost Track of Where You Are

Run /gsd-progress. It reads all state files and tells you exactly where you are and what to do next.

Model Costs Too High

Switch to budget profile: /gsd-config --profile budget. Disable research and plan-check agents via /gsd-settings if the domain is familiar.

Tuning model cost by phase (models) — added in v1.40

Add a models block to .planning/config.json:

{
  "model_profile": "balanced",
  "models": {
    "planning": "opus",
    "discuss": "opus",
    "research": "sonnet",
    "execution": "opus",
    "verification": "sonnet",
    "completion": "sonnet"
  }
}

Need a per-agent exception? Add model_overrides alongside — it wins over models:

{
  "models": { "research": "sonnet" },
  "model_overrides": {
    "gsd-codebase-mapper": "haiku"
  }
}

For the full mapping table and resolution-precedence rules, see Per-Phase-Type Models.

Cheap-by-default with dynamic_routing — added in v1.40

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

For the full agent → tier mapping, see Dynamic Routing.

Trim MCP servers to reduce per-turn cost

Before tuning model_profile or models.<phase_type>, audit which MCP servers your harness has enabled. Every enabled MCP server injects its tool schema into every turn — heavyweight servers can cost 20k+ tokens each.

This is a harness setting, not a GSD setting. The toggle lives in .claude/settings.json:

{
  "enabledMcpjsonServers": ["context7"],
  "disabledMcpjsonServers": ["playwright", "mac-tools"]
}

Quick audit before a long phase:

  • Are any browser / playwright tools enabled when this phase has no UI work?
  • Are any platform-specific tools enabled when not needed?
  • Are any project-specific MCPs from a different project still enabled here?

Each disabled server removes its schema from every subsequent turn. Trimming MCPs compounds with model_profile tuning — both levers are additive, and MCP savings show up immediately across every subagent the orchestrator spawns.

For the full audit, harness reference, and the composition note with model_profile, see MCP Tool Schema Cost in the bundled context-budget.md reference.

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

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

If you installed GSD for a non-Claude runtime, the installer already configured model resolution. No manual setup is needed — resolve_model_ids: "omit" is set automatically, which tells GSD to skip Anthropic model ID resolution and let the runtime choose its own default model.

To assign different models on a non-Claude runtime:

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

Codex skill picker and agent scheduling (#774)

GSD enriches each Codex install with an additional artifact:

  • Flex-tier scheduling — light-tier agents (haiku-equivalent) emit service_tier = "flex" and model_verbosity = "low" in their agent TOML. The Codex scheduler routes these agents to the flex tier (lower cost, background processing) and suppresses verbose token output.

GSD skills appear in the Codex /skills picker via their SKILL.md file, which Codex discovers automatically. No agents/openai.yaml sidecar is emitted — doing so caused duplicate autocomplete entries (#1326).

This enrichment is written automatically at install time and requires no manual configuration. Requires Codex CLI ≥ 0.130.0.

Switching from Claude to Codex with one config change (#2517)

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

See Runtime-Aware Profiles.

Per-runtime command enrichment

When generating artifacts, the installer adapts GSD commands to each runtime's native command schema:

  • Qwen Code — main-loop skills carry Qwen's numeric priority field so the most-used workflows (e.g. new-project, plan-phase, execute-phase) sort first in the /skills list; utility skills are left unset. Higher values sort earlier; the field affects only the /skills list order.

See How to install GSD Core on your runtime for the full per-runtime details.

Manual install / no-Node.js setup

If you cannot run the GSD installer, you cannot use the source files in agents/ directly — they are in Claude Code's native frontmatter format. For OpenCode, two transformations are required:

Field GSD source format OpenCode-valid format Action
tools: Read, Bash, Grep (comma-string) Not a frontmatter field Remove the tools: line entirely
color: Plain CSS color name Hex or OpenCode semantic name Convert to hex or remove

Alternative: run the installer on any machine with Node.js:

npx @opengsd/gsd-core@latest --opencode --global

Installing for Cline

npx @opengsd/gsd-core --cline --global   # applies to all projects
npx @opengsd/gsd-core --cline --local    # this project only

Installing for CodeBuddy

npx @opengsd/gsd-core --codebuddy --global

GSD installs four surfaces for CodeBuddy: /gsd-* slash commands in ~/.codebuddy/commands/, subagents in ~/.codebuddy/agents/, model-invocable skills in ~/.codebuddy/skills/, and settings.json hooks. The skills are emitted with user-invocable: false so the slash commands are the single / menu surface (no duplicate entries).

Installing for Qwen Code

npx @opengsd/gsd-core --qwen --global

Installing for Prerelease Editions

Set the runtime's *_CONFIG_DIR env var to the prerelease directory before running the installer:

WINDSURF_CONFIG_DIR=~/.codeium/windsurf-next npx @opengsd/gsd-core@latest --windsurf --global

Env-var reference for supported runtimes:

Runtime Stable default Override env var
Claude Code ~/.claude CLAUDE_CONFIG_DIR
OpenCode XDG_CONFIG_HOME/opencode OPENCODE_CONFIG_DIR
Codex (per Codex CLI) --config-dir flag
Copilot ~/.copilot COPILOT_CONFIG_DIR (or COPILOT_HOME)
Cursor ~/.cursor CURSOR_CONFIG_DIR
Windsurf / Devin Desktop ~/.codeium/windsurf WINDSURF_CONFIG_DIR
Antigravity auto-detected ANTIGRAVITY_CONFIG_DIR
Augment ~/.augment AUGMENT_CONFIG_DIR
Trae ~/.trae TRAE_CONFIG_DIR
Qwen Code ~/.qwen QWEN_CONFIG_DIR
Kilo ~/.config/kilo KILO_CONFIG_DIR
CodeBuddy ~/.codebuddy CODEBUDDY_CONFIG_DIR
Cline ~/.cline CLINE_CONFIG_DIR

Using Claude Code with Non-Anthropic Providers

Switch to the inherit profile: /gsd-config --profile inherit. This makes all agents use your current session model.

Working on a Sensitive/Private Project

Set commit_docs: false during /gsd-new-project or via /gsd-settings. Add .planning/ to your .gitignore.

GSD Update Overwrote My Local Changes

Which recovery you need depends on whether you modified a GSD file or added your own:

  • You edited a file GSD ships (an agent prompt, a workflow). Since v1.17 the installer backs it up to gsd-local-patches/. Run /gsd-update --reapply to merge your changes back.

  • You added your own file inside a GSD-managed directory (a custom skill under skills/, an extra file in commands/gsd/). The installer saves it to gsd-user-files-backup/, and the update offers to restore it once the new version is installed. If you declined, or the backup is left over from an older update, restore it any time:

    node <config-dir>/gsd-core/bin/gsd-tools.cjs restore-custom-files --config-dir <config-dir> --apply
    

    Run it without --apply first to see what would be restored. The backup is never deleted, and the restore skips any file that would overwrite something the new release ships.

Install or Refresh a Release Candidate

To install or refresh GSD from the @next RC dist-tag (the pre-release channel established by ADR #660), run:

/gsd-update --next
# or equivalently:
/gsd-update --rc

The same scope/runtime detection, changelog preview, custom-file backup, and cache clearing apply. Omitting --next/--rc keeps targeting @latest (stable channel, no change). Only the @latest and @next channels are supported — no arbitrary dist-tag can be passed.

Cannot Update via npm

See docs/manual-update.md for a step-by-step manual update procedure.

Workflow Diagnostics (/gsd-forensics)

When a workflow fails in a non-obvious way, run /gsd-forensics to generate a diagnostic report covering git history anomalies, artifact integrity, and state inconsistencies. Output goes to .planning/forensics/.

Pre-populated Permissions (Claude Code)

Since v1.3.1, the installer pre-populates ~/.claude/settings.json (or settings.local.json for local installs) with the core permissions GSD needs:

{
  "permissions": {
    "allow": [
      "Bash(npx gsd-core *)",
      "Read(.planning/*)",
      "Edit(.planning/*)",
      "Read(STATE.md)",
      "Edit(STATE.md)"
    ]
  }
}

These entries eliminate first-run approval prompts for GSD's own tool calls. The merge is non-destructive — your existing permissions are preserved and GSD entries are only appended. Uninstalling GSD removes exactly these entries and preserves any others.

Secret-file protection moved from deny rules to a hook (#4221). Earlier versions also wrote three permissions.deny rules — Read(.env), Read(.env.*) and Read(.secrets). Claude Code 2.1.259 hardened the Bash-side enforcement of Read() deny rules so that any such rule makes every cd DIR && grep … / cd DIR && cat … compound prompt for approval, even in auto mode — and GSD's subagents emit hundreds of those per session. The same protection now ships as the always-on gsd-secret-read-guard.js PreToolUse hook (Read, Grep and Bash; see Runtime Hooks above for what it covers and its documented gaps). A hook denial is not a permission rule, so it never arms that check, and it applies in auto and bypassPermissions modes alike. On install and uninstall the three retired strings are removed from permissions.deny (and an emptied deny array is dropped). Note the removal is byte-exact: a rule you wrote by hand that is identical to one of the three is indistinguishable from the installer's and is removed as well — re-add it if you want both layers.

Executor Subagent Gets "Permission denied" on Bash Commands

Add the required patterns to ~/.claude/settings.json. Core patterns needed for all stacks:

"Bash(git add:*)",
"Bash(git commit:*)",
"Bash(git merge:*)",
"Bash(git worktree:*)",
"Bash(git rebase:*)",
"Bash(git reset:*)",
"Bash(git checkout:*)",
"Bash(git switch:*)",
"Bash(git restore:*)",
"Bash(git stash:*)",
"Bash(git rm:*)",
"Bash(git mv:*)",
"Bash(git fetch:*)",
"Bash(git cherry-pick:*)",
"Bash(git apply:*)",
"Bash(gh:*)"

Per-project permissions: add the same permissions.allow block to .claude/settings.local.json in your project root instead of ~/.claude/settings.json.

Parallel Execution Causes Build Lock Errors

GSD handles this automatically since v1.26. If you're on an older version, add to your project's CLAUDE.md:

## Git Commit Rules for Agents
All subagent/executor commits MUST use `--no-verify`.

To disable parallel execution entirely: /gsd-settings → set parallelization.enabled to false.


Recovery Quick Reference

Problem Solution
Lost context / new session /gsd-resume-work or /gsd-progress
Phase went wrong git revert the phase commits, then re-plan
Need to change scope /gsd-phase (default), /gsd-phase --insert, or /gsd-phase --remove
Something broke /gsd-debug "description" (add --diagnose for analysis without fixes)
STATE.md out of sync state validate then state sync — check the report's scope field, not just valid (interpret results)
Workflow state seems corrupted /gsd-forensics
Quick targeted fix /gsd-quick
Plan doesn't match your vision /gsd-discuss-phase [N] then re-plan
Costs running high /gsd-config --profile budget and /gsd-settings to toggle agents off
Update broke local changes /gsd-update --reapply
Custom file gone after an update gsd-tools restore-custom-files --config-dir <dir> --apply
Want session summary for stakeholder /gsd-pause-work --report
Don't know what step is next /gsd-progress --next
Parallel execution build errors Update GSD or set parallelization.enabled: false
