* docs(#3186): record the disk-strict completion decision in ADR-3180 7.4 The maintainer decided #2957 on 2026-08-08: disk state is authoritative and a ROADMAP checkbox is a human annotation with no machine authority. Section 7.4 still carried the OPEN QUESTION and was marked blocked, so the contract said one thing and the tracker another. Recorded per section 7's own rule - a behavior not stated there is not decided, and amending a rule is an ADR amendment rather than a code change with a comment. The decision comment names Phase 4's PR as the carrier of this edit and makes it an acceptance criterion that the text be in the tree before implementation begins, so this lands first, alone, ahead of any code. Also clears the stale blocked-on-2957 row in the guard roster. * refactor(#3186): one shared phase-completion predicate, disk-strict isPhaseComplete in verification.cts becomes the single owner. It calls readVerificationStatus UNCONDITIONALLY - plan count is not a precondition - so a zero-plan phase with a passing VERIFICATION.md is complete. That is #3168: init gated the read on a plan count and synthesized a not_required sentinel, so phase.complete succeeded while init.manager reported incomplete for the same phase. The guard, built and run before scope was fixed per Amendment 3, found 9 re-derivations where the ADR named 3. Four were unnamed, including one in the prompt layer: mvp-phase.md ORed a ticked checkbox with disk status, which under disk-strict is the divergence itself. Per the #2957 decision, a ticked ROADMAP checkbox is a human annotation with no machine authority. The overrides in roadmap analyze and init manager are deleted rather than generalized; the user's checkbox stays in ROADMAP.md, only its authority goes. scanPhasePlans.completed and buildWorkstreamInventory are deliberately NOT folded - they answer 'are all plans summarized', which is a different question, and folding them would either over-report completion or invert the dependency direction between Phase 1's owner and this one. Verified on the remote runner. * fix(#3186): close seven review findings and record the missing-verdict rule The isolated review reproduced a write-path regression I introduced: migrating cmdRoadmapUpdatePlanProgress dropped its summaryCount>=planCount gate, so a phase with a fresh passing verification plus a newly-added unsummarized plan reported complete AND wrote a checkbox into ROADMAP.md while phase complete refused. The owner stays right per 7.4 - plan count is not a completion precondition - so the gate is restored at the write site as an explicit composition, mirroring the separate 2648 unexecuted-plan gate cmdPhaseComplete already carries. The spec axis was right that my 0.x-split reasoning was too permissive. The 2957 decision names buildStateFrontmatter as one of the three that must converge, and buildWorkstreamInventory combined a summaries-met local with verification data to decide the same verdict - Decision 4(c)'s named bypass, and it reproduced 3168 in a third surface. Both now route through the owner. The raw scanPhasePlans helper stays: it answers are-plans-summarized, which genuinely is a different question. Maintainer decision recorded in 7.4: a missing verdict is not a passing one, so an absent VERIFICATION.md means not complete everywhere. That retires 2645's verifier-disabled tolerance and inverts its Goodhart incentive - deleting the evidence now lowers completion instead of raising it. Guard hardened: block-form count gates and algebraic restatements are caught, and the header now discloses its remaining limits instead of overclaiming. Verified on the remote runner. * fix(#3186): route state sync through the owner and catch bare completed reads The matrix found 52 failures. 51 were fixtures asserting the old semantics: a phase with plans and summaries but no VERIFICATION.md used to count complete and correctly no longer does. Each fixture now carries a passing verification where that is what the test was actually about, rather than having its assertion weakened. The 52nd was a real 10th re-derivation the guard could not see. cmdStateSync destructured scanPhasePlans().completed directly - a bare field read, not a comparison - and used it as a completion verdict, so state sync and state json disagreed on completed_phases for identical disk state. Routed through the owner. Guard gains shape (d): any read of .completed off a scanPhasePlans() result outside plan-scan.cts, in chained, destructured and indirect forms, function scoped with no line window. It cannot tell a summaries-met read from a completion read - that is data flow - so it flags every one and requires a written-reason exemption, which is the same discipline shapes a-c already use. The blind spot is disclosed in the header rather than overclaimed. The emitted-attribution failure was also mine, not pre-existing: the mvp-phase.md checkbox-OR removal moves emitted bytes, acknowledged in tests/emitted-drift-acks. Verified on the remote runner. * test(#3186): give the nested-plans sync fixture a passing verification Last 3 matrix failures were one failure echoing up two describe levels. Phase 01-alpha had plans and summaries but no VERIFICATION.md, so under disk-strict completed stayed 0 and no Progress change was emitted - correct new behavior, not a regression. Added the passing verification rather than dropping the Progress expectation, so the test still covers what #3257 is about: that a nested plans/ layout is counted and not undercounted. Probe against the built lib confirms Progress: 0% -> 50% alongside Total Plans in Phase: 0 -> 3. * chore(#3186): backfill changeset PR number pr:0 placeholder replaced with the real number now that #3306 exists. --------- 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
- Resolve an ESLint glob-coverage finding — bring a source file that matches no lint rule under coverage, or record a reasoned exemption
- 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
- Catch complexity before it compounds — enable the post-execute refactor hook, read a proposal's score vs. anchor delta, and accept or decline it
- 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
- Control which host runtime GSD reports — read the
agent_runtimeladder, understand what host detection looks at, and pin the runtime when detection is not what you want - 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
