* test(#2647): failing-first — fixer worktree path must be repo-relative not /tmp * fix(#2647): place code-fixer worktree under .claude/worktrees/, not /tmp The gsd-code-fixer agent hand-rolled its worktree at a hardcoded `/tmp/sv-${padded_phase}-reviewfix-XXXXXX` mktemp path. On Windows/Git Bash that landed OUTSIDE the project tree — outside the agent session's permission allowlist, so every Read inside the worktree prompted (~25/run) — and mktemp's MAX_PATH-avoidance substitute produced an un-removable `C:/mvwtNN` path. Place the worktree repo-relative under `.claude/worktrees/` (the same dir the harness-managed executor worktrees use: gitignored via `.claude/`, inside the session's permission scope), with a $$-PID + epoch suffix for concurrency uniqueness (replacing mktemp's XXXXXX). $main_repo is resolved the same way the cleanup tail already resolves it. Three sites updated: setup_worktree bash, concrete-steps prose, critical_rules. The #2990 `-b "$reviewfix_branch"` invariant is preserved (the folded test asserts it). Failing-first regression added to the #2990 suite in tests/agent-frontmatter.test.cjs. * test(#2647): update #2686 path assertion to expect .claude/worktrees/, not /tmp The #2686 regression test encoded the worktree location as a hardcoded `/tmp/sv-` path (matching sibling GSD agents at the time). #2647 showed that breaks Windows/Git Bash (worktree outside the project tree → permission prompts; mktemp MAX_PATH substitute un-removable). Update the #2686 path assertion to require the repo-relative `.claude/worktrees/` location and forbid `/tmp/sv-`. The #2686 isolation + cleanup assertions are unchanged. * fix(#2647): word-boundary wt= parse + ack the fixer growth vs next Two follow-ups to the #2647 GREEN run: - parseWtAssignments matched `prior_wt=` (no word boundary), polluting the set and tripping the repo-relative + concurrency-unique assertions. Anchor on (?:^|\s)wt= so only the real worktree-path assignment is captured. - emitted-attribution: gsd-code-fixer.md grew 1875 bytes vs origin/next. Update the emitted-drift-ack entry to attribute the #2647 worktree-path change (supersedes the prior #2825 attribution, whose growth is already in next). * fix(#2647): address review — validate padded_phase at the sink + tighten test Code-review + security-review both APPROVED with one actionable minor: padded_phase is interpolated into a worktree PATH and a git BRANCH NAME, but was only validated by the orchestrator (code-review-fix.md), not at the agent sink. The agent prompt is a literal bash contract any caller can spawn, so add a `[[ =~ ^[0-9]+(\.[0-9]+)?$ ]]` self-defense check rejecting traversal/shell metachars (defense-in-depth; not a present vuln — the only caller validates). Also tighten the concurrency-uniqueness test to require BOTH $$ AND $(date +%s) (either-alone was too lax per review). Update the emitted-drift-ack reason to cover the added validation growth. * changeset(#2647): code-fixer worktree under .claude/worktrees not /tmp * changeset(#2647): backfill PR number 2942 * chore(#2938): regenerate stale docs/CONTEXT-INDEX.json on next #2938 (#2928) updated the CONTEXT.md RULESET prose for the new per-PR emitted-drift-ack fragment mechanism (#2914) but shipped a CONTEXT-INDEX.json generated from the OLD prose. lint:generated-sync fails on every PR that rebases onto next after #2938 (the regen produces a 3-line diff bringing three RULESET entries — AGENT_SIZE_BUDGET, EMITTED_ATTRIBUTION, WORKFLOW_SIZE_BUDGET — in sync with the prose already on next). Mechanical regen via `node scripts/gen-context-index.cjs --write`; idempotent; surfaced by the #2647 rebase. No behavioral change. --------- Co-authored-by: sim <sim@users.noreply.github.com>
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
- 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

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
- Architecture — system architecture, agent model, and data flow
- The Embeddable Orchestration System — one public, versioned contract for embedding GSD across many hosts
- Discuss modes — assumptions mode vs interview mode for
/gsd-discuss-phase - Context monitoring — context window monitoring hook architecture
- Issue-driven orchestration — recipe for driving GSD from a tracker issue using existing primitives
