* fix(#1369): refresh wave manifest and re-check base before each wave in execute-phase Two compounding issues caused wave N+1 worktrees to fork from the stale pre-wave-N commit, immediately tripping the worktree_branch_check FATAL guard in every executor: 1. worktree.base-check auto-degrade only ran once at initialize time. After wave N merges advanced orchestrator HEAD past origin/HEAD, new worktrees were still forked from origin/HEAD (Claude Code "fresh" base). 2. WAVE_WORKTREE_MANIFEST was never unset between waves, so wave N+1 reused the consumed wave-N manifest file, which would have blocked the step 5.5 manifest guard (#3384) on subsequent waves. Fix: add two safeguards in execute-phase.md — - Step 0.5 (start of each wave): re-runs worktree.base-check; auto-degrades USE_WORKTREES=false for that wave when HEAD has diverged from origin/HEAD. - Step 7c (end of each wave): unsets WAVE_WORKTREE_MANIFEST so wave N+1 creates a fresh per-wave manifest; re-asserts worktree.set-baseref (idempotent) and re-evaluates base degradation after wave merges land. 17 regression tests added in tests/bug-1369-wave-stale-base.test.cjs. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(#1369): rename test to fix-NNN convention; update workflow size baseline Rename tests/bug-1369-wave-stale-base.test.cjs → tests/fix-1369-wave-stale-base.test.cjs to satisfy the lint-regression-test-names gate (new files cannot use bug-NNN prefix). Update tests/workflow-size-baseline.json for execute-phase.md: 93157 → 97393 (LF-normalized byte count after adding step 0.5 inter-wave base re-check and step 7c between-wave manifest reset). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(#1369): add issue reference to allow-test-rule comment Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(#1369): extract new execute-phase steps to references; satisfy ADR-857 cap Step 0.5 (inter-wave worktree base re-check) and steps 7b–7c (pre-wave dependency check + between-wave manifest reset/base refresh) added by this PR grew execute-phase.md to 97393 bytes, violating the ADR-857 phase-6 architectural mandate that host-loop bodies remain strictly below the pre-phase-6 baseline of 93166 bytes. Extract both new blocks into dedicated reference files: - gsd-core/references/execute-phase-wave-guard.md (step 0.5) - gsd-core/references/execute-phase-between-wave-reset.md (steps 7b + 7c) Replace inline prose with @-reference pointers. File now measures 92851 bytes (LF-normalized), satisfying the ADR-857 capstone conformance gate. Also update tests/workflow-size-baseline.json to 92851 and add both new reference files to docs/INVENTORY-MANIFEST.json. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(#1369): update regression tests to read from extracted reference files Steps 0.5 and 7b+7c were moved to reference files to satisfy the ADR-857 size cap on execute-phase.md. Tests now check @-reference pointers in the workflow for ordering and read content assertions from the reference files.

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
- 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
