* chore(#2992): widen the when= grammar and key the section manifest per workflow Epic #1671 Phase 6.1. Two blockers stopped the fragment model reaching any file beyond execute-phase.md: the when= vocabulary was frozen at 4 atoms (3 execute-phase-specific), and the section manifest was single-workflow by construction with 'execute-phase' hardcoded into buildSectionManifestField. - widen WHEN_VOCABULARY 4 -> 14 via a coordinated ADR-1671 amendment; the grammar stays CLOSED (one atom, no operators, negation or nesting) and WHEN_PREDICATES stays a hand-written literal map, never deriving a predicate from its atom string - InvocationFacts gains flags: ReadonlySet<string> plus three computed state booleans; add the missing reverse vocabulary/predicate parity guard - key the manifest artifact per workflow; a stale flat {sections:[...]} artifact now fails shape validation instead of being misattributed - wire the field into six init entry points and parse the flags each needs An atom ships only with both a real consuming section and a fact the init seam actually computes. Six surveyed atoms are withheld because their workflows have no dedicated init entry point; an atom without a computed fact evaluates false forever and silently disables its own section. Fixes a defect found while wiring: parseNamedArgs always materializes a boolean flag key, so folding its false into the absent sentinel is required or every flag reads as present and gating is silently always-on. Also resolves ADR-1671:194 by measurement: --mvp stays unmarkable, because its interleaved sites are always-run flag resolution and a ~340 byte block that already delegates lazily. Refs #2992 * fix(#2992): treat any falsy option value as an absent flag and reject unsafe manifest read paths Findings from two orthogonal reviews (Claude /code-review + an isolated adversarial pass); both independently reproduced the first one. - MAJOR: the flags-builder treated only `undefined` as absent, but parseNamedArgs yields `null` for an absent value-flag and `false` for an absent boolean-flag, so `--granularity` read as present on every plan-phase invocation. Fixed at the root: a flag is present iff its option value is truthy. The six per-handler `|| undefined` folds are now redundant and removed, which also closes the duplicate-translation and missed-onboard-handler findings. - MAJOR: state:needs-codebase-map had zero coverage. Added unit, property and real-CLI integration tests. - MINOR: reject absolute, UNC/drive and `..`-traversing `read` paths in the manifest, degrading the whole load to null like every other shape violation. Verified: `/etc/passwd` previously reached section_manifest.read. - MINOR: corrected a stale "4 to 20" doc comment; the vocabulary is 14. Refs #2992 * test(#2992): update the generator suite for the per-workflow manifest shape The remote matrix went red with 5 unique failures, identical on linux-node22 and linux-node24, all in tests/gen-section-manifest.test.cjs. Re-keying the artifact to {workflows:{...}} left this suite asserting the old flat {sections:[...]} shape; nothing else in the tree still does. - three tests read manifest.sections.length, now undefined; retargeted at workflows.<name> with their original intent preserved (a fenced or loop-host marker still asserts NO section is produced, not merely a changed count) - the stale-manifest test wrote its fixture in the OLD shape, so it tripped shape validation and stopped exercising staleness at all. Its fixture is now valid-but-mismatched so FAIL_STALE is genuinely reached again. - added the coverage that exposed: a pre-6.1 flat artifact must report FAIL_MANIFEST_MALFORMED_SHAPE. That is the real upgrade path for an installed tree and nothing covered it. Refs #2992 * chore(#2992): backfill changeset pr number to 3013 --------- Co-authored-by: sim <sim@local>
GSD Core documentation
Documentation is organised into four quadrants: tutorials help you learn by doing, how-to guides solve specific tasks, reference states authoritative facts, and explanation explores concepts and design decisions.
Language versions: English · Português (pt-BR) · 日本語 · 简体中文
Tutorials
- Your first project — install to first shipped phase, one guaranteed path
- Onboarding an existing codebase — bring GSD Core to a brownfield repo
- Build your first capability — author a tiny declarative capability and watch it act in the loop
- Install your first capability — install a third-party capability end-to-end: consent, verify, check for updates, remove
How-to guides
- Install on your runtime — runtime-specific install steps for all 16 supported runtimes
- Install a minimal GSD and add skills later — install only the core skills, then grow the surface with profiles and
/gsd:surface - Attach a plugin-provided skill to a GSD agent — use the
global:plugin:skillentry form to load Claude Code plugin skills into agent prompts - Discuss a phase — capture implementation decisions before planning begins
- Resolve edge-coverage findings — turn the spec phase's surfaced domain-boundary edges into covered, dismissed, or backstopped spec decisions
- Resolve prohibition findings — turn the spec phase's surfaced must-NOT constraints into resolved, dismissed, or deferred spec decisions
- Plan a phase — run research, decompose work, and verify plan quality
- Execute a phase — run plans in parallel waves with fresh-context subagents
- Verify and ship — walk through completed work, diagnose failures, and create the PR
- Run phases autonomously — use autonomous mode for unattended phase execution
- Handle quick and fast tasks — use
/gsd-quickand/gsd-fastfor ad-hoc work outside the phase loop - Configure model profiles — switch between quality, balanced, and budget model tiers
- Set up cross-AI review — configure a second AI to review code produced by the primary agent
- Work in parallel with workstreams — run independent lines of work simultaneously using workstreams
- Isolate work with workspaces — use workspaces to sandbox experimental or risky changes
- Debug a failed execution — diagnose and recover from broken or incomplete phase execution
- Spike and sketch — use
/gsd-spikeand/gsd-sketchfor exploratory work before committing to a plan - Design a UI phase — use the UI phase loop for frontend and visual work
- Develop a Capability for GSD 1.5+ — add feature Capabilities, hook fragments, and registry entries
- Ship a reviewer lane in your capability — declare a
reviewerbody so/gsd-reviewdiscovers, invokes, and renders your external review CLI or model endpoint - List your reviewer lane in the registry — publish a lane you have built to the Reviewer Lane Registry so other people can find and install it
- Take over a capability or EoS integration — assume maintainership of an existing third-party capability, reviewer lane, or EoS host integration through a handoff, an adoption fork, first-party absorption, or a de-listing
- Add or update a host's integration — set a host's documentation-sourced
runtime.hostIntegrationaxes (ADR-1239 Phase A), with theundocumentedsentinel rule - Turn a capability off (and keep it off) — disable a capability via the surface, or gate individual hooks off without removing the capability
- Drive GSD from a tracker issue — start a phase from a GitHub, Linear, or Jira issue
- Migrate from GSD 2 — upgrade an existing GSD 2 project to GSD Core
- Update GSD — re-run the installer to pick up the latest release
- Clean up get-shit-done-cc — remove leftover old-package artifacts that cause a spurious

Explanation
- Context engineering — how context rot forms and how GSD Core prevents it
- The phase loop — design rationale for the Discuss → Plan → Execute → Verify → Ship cycle
- Multi-agent orchestration — how subagents are spawned, scoped, and coordinated
- Security model — trust boundaries, permissions, and safe automation
- The capability trust model — why third-party capabilities are gated by consent + integrity + reversibility, not a sandbox
- How overlay capabilities compose — why first-party always wins and how the loader resolves precedence, conflicts, and fail-open load-failure warnings
