msd-core/gsd-core/workflows/settings-advanced.md

Interactive configuration of GSD power-user knobs — plan bounce, node repair, subagent timeouts, inline plan threshold, cross-AI execution, base branch, branch templates, response language, context window, gitignored search, graphify build timeout, runtime model tier overrides, and model policy configuration (provider + budget → canonical tier mapping, or manual model ID assignment per cost tier).

This is a companion to /gsd:settings — the common-case prompt there covers model profile, research/plan_check/verifier toggles, branching strategy, UI/AI phase gates, and worktree isolation. This advanced command covers everything else that is user-settable, grouped into eight sections so each prompt batch stays cognitively scoped. Every answer pre-selects the current value; numeric-input answers that are non-numeric are rejected and re-prompted.

<required_reading> Read all files referenced by the invoking prompt's execution_context before starting. </required_reading>

Ensure config exists and resolve the workstream-aware config path (mirrors `settings.md`):

• context_window (default: 200000)
• search_gitignored (default: false)

Runtime Model Tiers:

• runtime (default: null — reads as "claude")
• model_profile_overrides.<runtime>.opus (default: built-in for the runtime, or absent)
• model_profile_overrides.<runtime>.sonnet (default: built-in for the runtime, or absent)
• model_profile_overrides.<runtime>.haiku (default: built-in for the runtime, or absent)

Model Policy:

• model_policy.provider (default: null — known values: anthropic, anthropic-fable, openai, google, qwen)
• model_policy.budget (default: null — known values: high, medium, low)
• model_policy.high (default: null — model ID for the high-cost tier; used by generic provider path)
• model_policy.medium (default: null — model ID for the medium-cost tier; used by generic provider path)
• model_policy.low (default: null — model ID for the low-cost tier; used by generic provider path)

Each field's current value is pre-selected in the prompt rendering below. When the current value is absent from the config, render the documented default as the pre-selected option so the user sees what the effective value is.

Text mode (workflow.text_mode: true or --text flag): Set TEXT_MODE=true if --text is in $ARGUMENTS OR text_mode is true in config. When TEXT_MODE=true, replace every AskUserQuestion call below with a plain-text numbered list and ask the user to type the choice number or free-text value.

Numeric-input validation. For any numeric field (*_passes, *_budget, *_timeout, *_threshold, context_window, graphify.build_timeout), if the user types a value that is not a non-negative integer, the workflow MUST reject it, state which value was invalid, and re-prompt that single field. The minimum accepted value is field-specific and is stated in each field's prompt below — workflow.plan_bounce_passes and workflow.max_discuss_passes require >= 1; all other numeric fields accept >= 0. An empty input means "keep current" — the existing value is retained. Non-numeric input is never silently coerced.

Free-text validation. For branch template fields (git.phase_branch_template, git.milestone_branch_template), if the user supplies a non-default value, it MUST be non-empty and SHOULD contain at least one {placeholder}. A template missing placeholders is rejected with a message explaining the available variables ({phase}, {slug}, {milestone}) and re-prompted. An empty input means "keep current."

Null-allowed fields. For response_language, workflow.plan_bounce_script, workflow.cross_ai_command: an empty input clears the field (null). A non-empty input is stored verbatim as a string.

Section 7 — Runtime Model Tiers

This section lets the user inspect and override the built-in model IDs GSD resolves for each profile tier (opus / sonnet / haiku) on their configured runtime.

Step A — Show current runtime and built-in defaults:

Read runtime from the config (or treat as "claude" if absent). Look up the built-in tier map from the table below. For each tier, also read the current override from model_profile_overrides.<runtime>.<tier> if present.

Built-in tier defaults by runtime:

Runtime	opus	sonnet	haiku
claude	claude-opus-4-8	claude-sonnet-4-6	claude-haiku-4-5
codex	gpt-5.5	gpt-5.3-codex	gpt-5.4-mini
gemini	gemini-3-pro	gemini-3-flash	gemini-2.5-flash-lite
qwen	qwen3-max-2026-01-23	qwen3-coder-plus	qwen3-coder-next
opencode	anthropic/claude-opus-4-8	anthropic/claude-sonnet-4-6	anthropic/claude-haiku-4-5
copilot	claude-opus-4-8	claude-sonnet-4-6	claude-haiku-4-5
hermes	anthropic/claude-opus-4-8	anthropic/claude-sonnet-4-6	anthropic/claude-haiku-4-5
Group B (kilo, cline, cursor, windsurf, augment, trae, codebuddy, antigravity)	(no built-in default — your runtime handles model selection)

Display a table to the user showing the effective configuration:

Runtime model tiers — runtime: <current runtime or "claude (default)">

| Tier   | Built-in default                  | Current override (if any)         |
|--------|-----------------------------------|-----------------------------------|
| opus   | <built-in or "(no built-in)">     | <override value or "(none)">      |
| sonnet | <built-in or "(no built-in)">     | <override value or "(none)">      |
| haiku  | <built-in or "(no built-in)">     | <override value or "(none)">      |

For Group B runtimes (those without a built-in default), show (no built-in default — your runtime handles model selection) in the built-in column.

Step B — Let the user choose a runtime (optional):

AskUserQuestion([
  {
    question: "Which runtime group do you want to configure tier overrides for? (current: <runtime or 'claude'>)",
    header: "Runtime Group",
    multiSelect: false,
    options: [
      { label: "Keep current (<runtime>)", description: "Configure overrides for the current runtime." },
      { label: "Common runtimes", description: "claude, codex, gemini, qwen" },
      { label: "Additional runtimes", description: "opencode, copilot, hermes" },
      { label: "Other (Group B or custom)", description: "kilo, cline, cursor, windsurf, augment, trae, codebuddy, antigravity, or a custom runtime string." }
    ]
  }
])

If "Common runtimes" is selected, ask:

AskUserQuestion([
  {
    question: "Choose the runtime:",
    header: "Common",
    multiSelect: false,
    options: [
      { label: "claude", description: "Claude Code / Anthropic CLI." },
      { label: "codex", description: "OpenAI Codex CLI." },
      { label: "gemini", description: "Gemini CLI." },
      { label: "qwen", description: "Qwen CLI." }
    ]
  }
])

If "Additional runtimes" is selected, ask:

AskUserQuestion([
  {
    question: "Choose the runtime:",
    header: "Additional",
    multiSelect: false,
    options: [
      { label: "opencode", description: "OpenCode (uses anthropic/ prefix)." },
      { label: "copilot", description: "GitHub Copilot." },
      { label: "hermes", description: "Hermes (uses anthropic/ prefix)." }
    ]
  }
])

If "Other (Group B or custom)" is selected, prompt the user to enter the runtime name as a free-text string. If the selected runtime differs from the stored runtime key, update runtime via gsd-tools.cjs query config-set runtime <value> before proceeding to Step C.

Step C — Configure tier overrides for the selected runtime:

AskUserQuestion([
  {
    question: "Override for opus tier? Built-in: <opus default or '(no built-in)'>  Current: <override or '(none)'>",
    header: "Opus Override",
    multiSelect: false,
    options: [
      { label: "Keep current", description: "Leave unchanged (uses built-in default if no override)." },
      { label: "Clear override", description: "Remove any existing override; fall back to built-in." },
      { label: "Enter model ID", description: "Type the exact model ID string to use for opus-tier agents on this runtime." }
    ]
  },
  {
    question: "Override for sonnet tier? Built-in: <sonnet default or '(no built-in)'>  Current: <override or '(none)'>",
    header: "Sonnet Override",
    multiSelect: false,
    options: [
      { label: "Keep current", description: "Leave unchanged." },
      { label: "Clear override", description: "Remove any existing override; fall back to built-in." },
      { label: "Enter model ID", description: "Type the exact model ID string to use for sonnet-tier agents on this runtime." }
    ]
  },
  {
    question: "Override for haiku tier? Built-in: <haiku default or '(no built-in)'>  Current: <override or '(none)'>",
    header: "Haiku Override",
    multiSelect: false,
    options: [
      { label: "Keep current", description: "Leave unchanged." },
      { label: "Clear override", description: "Remove any existing override; fall back to built-in." },
      { label: "Enter model ID", description: "Type the exact model ID string to use for haiku-tier agents on this runtime." }
    ]
  }
])

Step D — Apply the changes:

For each tier where the user chose "Enter model ID":

gsd_run query config-set model_profile_overrides.<runtime>.<tier> "<model-id>"

For each tier where the user chose "Clear override", remove the key by setting it to null:

gsd_run query config-set model_profile_overrides.<runtime>.<tier> null

"Keep current" selections are skipped entirely. Never write a key the user did not explicitly change.

Merge the new settings into the existing config at `$GSD_CONFIG_PATH`. This merge is the core correctness invariant: **preserve every unrelated key** — do not clobber siblings.

Apply each selected value via gsd-tools.cjs query config-set <key> <value> so the central validator (isValidConfigKey) accepts the write and the deep-merge preserves unrelated keys and sibling sub-objects.

# Example — only write keys the user changed. "Keep current" selections are skipped.
gsd_run query config-set workflow.plan_bounce_passes 5
gsd_run query config-set workflow.subagent_timeout 900
gsd_run query config-set git.base_branch main
gsd_run query config-set context_window 1000000
# Runtime model tier examples:
gsd_run query config-set runtime gemini
gsd_run query config-set model_profile_overrides.gemini.opus gemini-3-ultra
gsd_run query config-set model_profile_overrides.gemini.haiku null

Conceptual shape after merge (unchanged top-level keys like model_profile, granularity, mode, brave_search, agent_skills.*, hooks.context_warnings, and anything not listed in Sections 1–8 MUST survive the update):

Never emit a full overwrite of the file that omits keys the user did not touch. Always route each write through gsd-tools.cjs query config-set so sibling preservation is handled by the central setter.

Section 8 — Model Policy

This section configures the model_policy key in .planning/config.json. Model policy defines which AI models GSD uses at each cost tier (low / medium / high), independently of the runtime and model_profile selections above. Two paths are offered:

• Known provider: choose a provider and a budget level; GSD materializes the canonical tier mapping for that provider.
• Generic provider: enter low / medium / high model IDs manually.

Step A — Read and display the current model policy:

cat "$GSD_CONFIG_PATH" | python3 -c "import sys,json; c=json.load(sys.stdin); mp=c.get('model_policy',{}); print(json.dumps(mp,indent=2))" 2>/dev/null || echo "{}"

Display the current values (or "(unset)" for any absent field) before asking:

Current model_policy:
  provider : <value or "(unset)">
  budget   : <value or "(unset)">
  low      : <value or "(unset)">
  medium   : <value or "(unset)">
  high     : <value or "(unset)">

Step B — Choose configuration path:

AskUserQuestion([
  {
    question: "How do you want to configure the model policy?",
    header: "Model Policy",
    multiSelect: false,
    options: [
      { label: "Known provider", description: "Choose a provider (Claude / OpenAI / Gemini / Qwen) and a budget level — GSD writes the canonical tier mapping automatically." },
      { label: "Generic provider", description: "Enter low / medium / high model IDs manually for any provider or custom deployment." },
      { label: "Keep current", description: "Leave model_policy unchanged." }
    ]
  }
])

If "Keep current" is selected: skip Steps C–E and move on to the confirm step.

Step C — Known-provider path:

AskUserQuestion([
  {
    question: "Which provider?",
    header: "Provider",
    multiSelect: false,
    options: [
      { label: "anthropic", description: "claude-opus-4-8 / claude-sonnet-4-6 / claude-haiku-4-5 (Anthropic / Claude)" },
      { label: "anthropic-fable", description: "claude-fable-5 / claude-sonnet-4-6 / claude-haiku-4-5 (Anthropic / Claude Fable opt-in)" },
      { label: "openai", description: "gpt-5.5 / gpt-5.3-codex / gpt-5.4-mini (OpenAI / Codex)" },
      { label: "Other known provider", description: "Type google or qwen; both still use the canonical tier mapping." }
    ]
  }
])

If the user selects "Other known provider", ask them to type google or qwen. Use the typed value as the provider. After the user picks or types a provider, ask:

AskUserQuestion([
  {
    question: "Which budget level?",
    header: "Budget",
    multiSelect: false,
    options: [
      { label: "high", description: "All tiers use the highest-quality model for the chosen provider. Highest cost." },
      { label: "medium", description: "High tier → top model; medium → mid model; low → cheapest model. Best cost/quality ratio." },
      { label: "low", description: "All tiers use the cheapest model for the chosen provider. Lowest cost." }
    ]
  }
])

Canonical tier mappings by provider and budget:

Provider	Budget	high	medium	low
anthropic	high	claude-opus-4-8	claude-opus-4-8	claude-sonnet-4-6
anthropic	medium	claude-opus-4-8	claude-sonnet-4-6	claude-haiku-4-5
anthropic	low	claude-haiku-4-5	claude-haiku-4-5	claude-haiku-4-5
anthropic-fable	high	claude-fable-5	claude-fable-5	claude-sonnet-4-6
anthropic-fable	medium	claude-opus-4-8	claude-sonnet-4-6	claude-haiku-4-5
anthropic-fable	low	claude-haiku-4-5	claude-haiku-4-5	claude-haiku-4-5
openai	high	gpt-5.5	gpt-5.5	gpt-5.5
openai	medium	gpt-5.5	gpt-5.3-codex	gpt-5.4-mini
openai	low	gpt-5.4-mini	gpt-5.4-mini	gpt-5.4-mini
google	high	gemini-3-pro	gemini-3-pro	gemini-3-pro
google	medium	gemini-3-pro	gemini-3-flash	gemini-2.5-flash-lite
google	low	gemini-2.5-flash-lite	gemini-2.5-flash-lite	gemini-2.5-flash-lite
qwen	high	qwen3-max-2026-01-23	qwen3-max-2026-01-23	qwen3-max-2026-01-23
qwen	medium	qwen3-max-2026-01-23	qwen3-coder-plus	qwen3-coder-next
qwen	low	qwen3-coder-next	qwen3-coder-next	qwen3-coder-next

Look up the selected (provider, budget) row and proceed to Step E to write those values.

claude runtime note: On the default claude runtime, policy-resolved model IDs (e.g. claude-fable-5) are mapped to Claude Code agent aliases (fable, opus, sonnet, haiku); an ID with no corresponding alias emits a stderr warning and falls back to the configured tier alias.

Step D — Generic-provider path:

Prompt the user to enter each model ID as a free-text input. An empty input means "keep the current value for that tier." Validate that non-empty inputs are non-blank strings (no whitespace-only values); if validation fails, re-prompt that single field.

AskUserQuestion([
  {
    question: "Model ID for the HIGH-cost tier? (most capable model — used for heavy reasoning tasks)",
    header: "High-tier model",
    multiSelect: false,
    options: [
      { label: "Keep current", description: "Leave unchanged (current: <model_policy.high or '(unset)'>)." },
      { label: "Enter model ID", description: "Type the exact model identifier. Non-blank string required." }
    ]
  },
  {
    question: "Model ID for the MEDIUM-cost tier? (balanced model — used for most agents)",
    header: "Medium-tier model",
    multiSelect: false,
    options: [
      { label: "Keep current", description: "Leave unchanged (current: <model_policy.medium or '(unset)'>)." },
      { label: "Enter model ID", description: "Type the exact model identifier." }
    ]
  },
  {
    question: "Model ID for the LOW-cost tier? (cheapest model — used for lightweight/fast tasks)",
    header: "Low-tier model",
    multiSelect: false,
    options: [
      { label: "Keep current", description: "Leave unchanged (current: <model_policy.low or '(unset)'>)." },
      { label: "Enter model ID", description: "Type the exact model identifier." }
    ]
  }
])

Set provider = "custom" and budget = null when writing the generic-provider result. Proceed to Step E.

Step E — Write model_policy to config:

# Known-provider path — write all four keys atomically:
gsd_run query config-set model_policy.provider "<provider>"   # e.g., anthropic / anthropic-fable / openai / google / qwen
gsd_run query config-set model_policy.budget   "<budget>"    # high / medium / low
gsd_run query config-set model_policy.high     "<high-id>"
gsd_run query config-set model_policy.medium   "<medium-id>"
gsd_run query config-set model_policy.low      "<low-id>"

# Generic-provider path — write only tiers the user changed ("Keep current" skipped):
gsd_run query config-set model_policy.provider "custom"
gsd_run query config-set model_policy.budget   null
# Per-tier writes for each non-"Keep current" answer:
gsd_run query config-set model_policy.high     "<high-id>"   # omit if user chose "Keep current"
gsd_run query config-set model_policy.medium   "<medium-id>" # omit if user chose "Keep current"
gsd_run query config-set model_policy.low      "<low-id>"    # omit if user chose "Keep current"

Never write a tier the user explicitly chose to keep; the existing value must survive.

For common-case toggles (model profile, research/plan_check/verifier, branching strategy,
UI/AI phase gates), use /gsd:settings.
