* feat(#1733): normalize-path-in-content production AST rule (Phase 5) ADR-1703 Phase 5 — the first production-code rule. local/normalize-path-in-content (src/**/*.cts, @typescript-eslint/parser): flags a path-returning fn result (path.basename excluded — returns a separator-less filename) interpolated into an @-reference / config-dir markdown body without .replace(/\\/g,'/') normalization, per RULESET.CONTENT-PATH-NORMALIZATION / DEFECT.WINDOWS-PATH-LEAK-IN-MARKDOWN-CONTENT. Build-and-assess found the canonical defect site (computePathPrefix) already compliant and only 1 src/ hit — a false positive (path.basename in a status message) — eliminated by narrowing (exclude basename; require a real @-ref/ config-dir marker, not bare .md). 0 src/ violations: clean forward-prevention. The out-of-band disable-ban now scans src/**/*.cts too (typescript-estree) so the production rule also cannot be eslint-disabled. Registered (error) + PROTECTED_RULES; CONTEXT.md predicates + how-to doc updated. - RuleTester suite (26 cases) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * docs(#1733): add changeset for Windows agent-skills path-leak fix Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix: harden mutation-matrix.cjs stdin read against EAGAIN on non-blocking pipe scripts/mutation-matrix.cjs read piped stdin via readFileSync(process.stdin.fd). On macOS libuv marks the stdin pipe fd non-blocking, so a synchronous read can throw EAGAIN before the writer fills the pipe — intermittently, under heavy CI shard load — aborting the script (status 2) and flaking mutation-matrix-ratchet. Replace with readStdinSync(): an fs.readSync loop that retries on EAGAIN (1ms synchronous Atomics.wait yield), stops on 0-byte/EOF, and rethrows other errors. Deterministic regression test injects EAGAIN via an fs.readSync monkeypatch. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * ci: re-run golden-install-parity on src/lib + installer changes (close drift guard) golden-install-parity hashes every installed bin/lib/*.cjs per runtime, so it must re-run whenever the built lib could change. ci-test-scope selected it for neither src/** nor installer changes, so a source-only edit (e.g. #1691's milestone.cts/roadmap.cts) recompiled bin/lib and silently drifted the golden fixtures past the scoped lane. Add golden-install-parity.test.cjs to both the 'TS runtime sources' and 'installer and package layout' selection rules, with behavioral regression tests for each.

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
- 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
⬆ /gsd:updateindicator after migrating to@opengsd/gsd-core - Fix the worktree base-mismatch (exit 42) error — resolve the branch-divergence condition that halts parallel phase execution
- Recover and troubleshoot — fix common problems, rebuild context, and uninstall

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-closed gates
- Architecture — system architecture, agent model, and data flow
- 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
