* fix(#683): auto-degrade phase execution to sequential on worktree base mismatch Claude Code forks worktree-isolated executors off the repository default branch (origin/HEAD), not the orchestrator's HEAD. Running /gsd-execute-phase on a branch diverged from the default (unmerged milestone/feature branch) left every executor without the phase's plan files and tripped the worktree-branch-check guard with `exit 42` — 100% reproducible, all OSes. - New module src/worktree-base-ref.cts: HEAD-vs-fork-base drift detection (origin/HEAD with symbolic-ref fallback) and no-clobber worktree.baseRef management, exposed as `worktree base-check` / `worktree set-baseref`. - execute-phase.md: pre-dispatch, for Claude Code with worktrees enabled, auto-degrades the run to sequential on the main tree when a base mismatch is detected, recommending worktree.baseRef:"head". The exit-42 guard stays as a backstop. - Installer: fresh local Claude installs set worktree.baseRef:"head" in .claude/settings.local.json (no-clobber, respecting an explicit shared settings.json value); upgrades print an opt-in notice pointing at `gsd-tools worktree set-baseref`. - Docs: how-to guide, CLI/config reference, planning-config cross-ref. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#683): auto-apply worktree.baseRef on upgrade; gate fresh+upgrade on use_worktrees Per maintainer direction: on a local Claude Code UPGRADE, set worktree.baseRef:"head" automatically (no opt-in notice) when the project's workflow.use_worktrees is enabled, instead of merely printing a remediation notice. For consistency the FRESH path is now gated the same way: both paths compute worktrees-enabled once (bounded walk-up read of .planning/config.json, default enabled unless workflow.use_worktrees === false) and apply the no-clobber baseRef only when enabled — never overwriting an explicit value in settings.local.json or a shared settings.json. gsd-tools worktree set-baseref remains for manual use. Docs + changeset updated; tests hardened (file-exists assertions, fresh+disabled case, upgrade idempotency). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#683): measure workflow byte-budget on LF, fixing Windows-only CI failure The workflow-size-budget test failed only on Windows: git checks out the .md files as CRLF (no eol=lf in .gitattributes) and byteCount used fs.statSync().size (raw on-disk bytes), counting an extra \r per line. That inflated execute-phase.md — the XL high-water-mark file pinned near its ceiling by the tighten-only ratchet — from 88492 LF bytes to ~90245 on Windows, over the 90000 XL ceiling, while passing on the LF-checkout Mac/Linux runners. The ceilings are explicitly "calibrated against raw `wc -c`" on an LF checkout, so the measurement should be LF-based on every platform. byteCount now reads the file and counts Buffer.byteLength after stripping CR, making the budget platform-independent (a no-op on LF checkouts; verified statSync === normalized for all 88 workflow files). No ceilings changed. Added a regression test asserting CRLF and LF content of the same file count identically. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#683): make worktree-base-ref test path mocks Windows-safe (path.join) tests/worktree-base-ref.test.cjs keyed its injected readFile/writeFile mocks (and a few expected `file` values) with forward-slash template literals like `${claudeDir}/settings.local.json`. The module composes those paths with path.join(), which emits backslashes on Windows, so the mock keys never matched the module's lookup → readFile returned null → resolveEffectiveBaseRef / cmdWorktreeBaseCheck / cmdWorktreeSetBaseRef (and the JSONC variants) failed on the Windows full-test runner only (they passed on Mac/Linux, and the install tests passed because they use the real filesystem). The module is correct; only the test fixtures hardcoded '/'. All mock keys and path assertions now use path.join(base, ...) mirroring the module, so they match on every platform (no-op on POSIX). 19 path references across 16 lines.

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
How-to guides
- Install on your runtime — runtime-specific install steps for all 15 supported runtimes
- Discuss a phase — capture implementation decisions before planning begins
- 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
- 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
