* test(installer): add regression tests for #3670 migration lock self-deadlock - T1: same-process PID re-entry reclamation (primary regression) - T2: dead-PID stale lock reclamation - T3: unlinkSync EPERM surfaces (not silently swallowed via force:true) - T4: counter-test — normal round-trip still works - T5: counter-test — genuinely-held live lock still errors clearly - Update existing 'reports lock release failures' test to mock fs.unlinkSync (not fs.rmSync) matching the fixed release path Windows wall-clock deadlock repro depends on Docker matrix Windows runners. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(installer): break migration lock self-deadlock on Windows (#3670) Root cause: `acquireInstallMigrationLock` release closure called `fs.rmSync(lockPath, { force: true })`. On Windows NTFS, a file recently closed via `closeSync(fd)` may still return EPERM from `unlink` until the OS fully releases the handle. The `force: true` flag silently swallows EPERM, leaving the lock file on disk. The subsequent `runInstallerMigrations` call in the same install() invocation hits EEXIST, spins for 30 s, then throws "installer migration lock is held". Fix: 1. Release closure uses `fs.unlinkSync` (not rmSync+force) so EPERM propagates via releaseError instead of being swallowed. 2. `acquireInstallMigrationLock` closes the fd before writing the payload (path-based write), eliminating the open handle that caused the deferred EPERM on Windows. 3. Stale-lock reclamation: on EEXIST, parse the on-disk PID and reclaim immediately if it matches process.pid (same-process re-entry, the primary #3670 failure mode) or if the PID is dead (ESRCH). Live alien PIDs still trigger the 30 s timeout. 4. Error message on a genuinely-held lock now includes the holder PID and acquiredAt timestamp for operator diagnostics. No public API change. All callers of runInstallerMigrations are inside installer-migrations.cjs and bin/install.js. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * chore(3670): update changeset to reference PR #3765 * fix(3670): timeout on reclaim-unlink failure to prevent spin-loop regression When unlinkSync throws (e.g. Windows EPERM on an open handle) in the same-PID / dead-PID reclamation path, the original code continued unconditionally — bypassing the timeout check and reintroducing the exact deadlock the PR is supposed to fix. Guard the continue behind a `reclaimed` flag: only loop back to openSync if unlink SUCCEEDED. On failure, fall through to the existing bounded sleep + timeout, which surfaces "installer migration lock is held" within lockTimeoutMs instead of spinning indefinitely. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * test(3670): tighten T5 — assert bounded failure when reclaim unlink fails on live lock The old T5 accepted BOTH success and throw, which allowed over-reclamation of a genuinely un-reclaimable lock to pass undetected. Rewrite T5 to force deterministically unreclaimable conditions: - Pre-seed lock with process.pid (triggers isSameProcess path) - Mock fs.unlinkSync via mock.method() to throw EPERM for the lock file With the production fix: reclaimed=false → falls through to timeout → throws "installer migration lock is held" within ~200ms. Without the production fix: unlink throws but continue runs anyway → process spins and eventually OOMs (confirmed RED: 136s runtime, V8 heap exhaustion from infinite readLockFile + new Error() allocations). assert.throws() now makes success a hard failure, closing the over-reclamation gap. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(3670): clean up orphan lock file when writeFileSync fails after closeSync If closeSync(fd) succeeds (fd=null) but the subsequent writeFileSync throws, the empty lock file was left on disk. readLockFile returns null for an empty/invalid-JSON file, so the stale-lock reclamation path skips it, causing the next acquire attempt to spin to timeout. Track ownership with lockCreatedByUs flag; add a second cleanup branch in the catch block for the fd-already-closed case. Also fix changeset body to use the bold-prefix format required by all other fragments in .changeset/.

Returning to GSD?
Run
/gsd-map-codebaseto re-index your codebase, then/gsd-new-projectto rebuild GSD's planning context. Your code is fine — GSD just needs its context rebuilt. See the CHANGELOG for what's new.
Why I Built This
I'm a solo developer. I don't write code — Claude Code does.
Other spec-driven tools exist, but they're all built for 50-person engineering orgs — sprint ceremonies, story points, stakeholder syncs, Jira workflows. I'm not that. I'm a creative person trying to build great things consistently.
So I built GSD. The complexity is in the system, not in your workflow. Behind the scenes: context engineering, XML prompt formatting, subagent orchestration, state management. What you see: a few commands that just work.
The system gives Claude everything it needs to do the work and verify it. I trust the workflow. It just does a good job.
— TÂCHES
How It Works
The loop is six commands. Each one does exactly one thing.
1. Initialize
/gsd-new-project
Questions → research → requirements → roadmap. You approve it, then you're ready to build.
Already have code? Run
/gsd-map-codebasefirst. It analyzes your stack, architecture, and conventions so/gsd-new-projectasks the right questions.
2. Discuss
/gsd-discuss-phase 1
Your roadmap has a sentence per phase. That's not enough to build it the way you imagine it. Discuss captures your decisions before anything gets planned: layouts, API shapes, error handling, data structures — whatever gray areas exist for this specific phase.
The output feeds directly into research and planning. Skip it, get reasonable defaults. Use it, get your vision.
3. Plan
/gsd-plan-phase 1
Research → plan → verify, in a loop until the plans pass. Each plan is small enough to execute in a fresh context window.
4. Execute
/gsd-execute-phase 1
Plans run in parallel waves. Each executor gets a fresh 200k-token context. Each task gets its own atomic commit. Walk away, come back to completed work with a clean git history.
Your main context window stays at 30–40%. The work happens in the subagents.
5. Verify
/gsd-verify-work 1
Walk through what was built. Anything broken gets a diagnosed fix plan — ready for immediate re-execution. You don't debug manually; you just run execute again.
6. Repeat → Ship
/gsd-ship 1
/gsd-complete-milestone
/gsd-new-milestone
Loop discuss → plan → execute → verify → ship until the milestone is done. Then archive, tag, and start the next one fresh.
Getting Started
npx get-shit-done-cc@latest
The installer prompts for your runtime (Claude Code, OpenCode, Gemini CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more) and whether to install globally or locally.
claude --dangerously-skip-permissions
GSD is built for frictionless automation. Skip-permissions is how it's intended to run.
Install only the skills you need with --profile=core (six core-loop skills), --profile=standard (core + phase management), or the default full install. Profiles compose: --profile=core,audit. --minimal is an alias for --profile=core. See docs/USER-GUIDE.md for the full walkthrough, non-interactive install flags for all 15 runtimes, and permissions configuration. See ADR-0011 for the profile model and runtime surface control.
Current release highlights are in docs/RELEASE-v1.42.1.md: package legitimacy checks, safer installer migrations, runtime surface control, custom ship PR sections, reviewer defaults, fallow structural review, and quota-aware execution recovery.

Why It Works
Three things most AI-coding setups get wrong:
1. Context bloat. As a session grows, quality degrades. GSD keeps your main context clean by doing the heavy work in fresh subagent contexts. Researchers, planners, and executors each start fresh with exactly what they need.
2. No shared memory. GSD maintains structured artifacts that survive session boundaries: PROJECT.md (vision), REQUIREMENTS.md (scope), ROADMAP.md (where you're going), STATE.md (current position and decisions), CONTEXT.md (per-phase implementation decisions). Every new session loads these and knows exactly where things stand.
3. No verification. Code that "runs" isn't code that "works." GSD's verify step walks you through what was built, diagnoses failures with dedicated debug agents, and generates fix plans before you declare a phase done.
See docs/ARCHITECTURE.md for how the multi-agent orchestration and context engineering work in detail.
Configuration
Settings live in .planning/config.json. Configure during /gsd-new-project or update with /gsd-settings.
Key dials:
| Setting | What it controls |
|---|---|
mode |
interactive (confirm each step) or yolo (auto-approve) |
| Model profiles | quality / balanced / budget — controls which model each agent uses |
workflow.research / plan_check / verifier |
Toggle the quality agents that add tokens and time |
parallelization.enabled |
Run independent plans simultaneously |
Optional structural review: set code_quality.fallow.enabled to true to add a fallow pre-pass to /gsd-code-review. GSD writes .planning/phases/<phase>/FALLOW.json and surfaces a Structural Findings (fallow) section in REVIEW.md. Install with npm install -D fallow@^2.70.0 (or system-wide via cargo install fallow; note that the Rust binary's JSON schema must match the documented v2.70+ contract — older versions may produce silent zero-finding output).
Package legitimacy checks are built into the research, planning, and execution path: recommended dependencies get audited, unverified packages require a human checkpoint, and failed installs stop instead of trying similarly named alternatives.

Troubleshooting
Commands not showing up? Restart your runtime after install. GSD installs to ~/.claude/skills/gsd-*/ (Claude Code), ~/.codex/skills/gsd-*/ (Codex), or the equivalent for your runtime.
Codex users — minimum supported CLI version is 0.130.0. Codex CLI 0.130.0 (release notes) removed extra-skill-roots discovery via openai/codex#21485; from that version onward Codex discovers skills from standard roots (including ~/.codex/skills/<name>/SKILL.md). GSD installs there directly. Earlier Codex CLI versions may still discover additional roots, which can surface duplicate gsd-* entries (one from extra-roots discovery, one from ~/.codex/skills/); restart Codex after install and either upgrade or accept the duplicate listing.
Something broken? Re-run the installer — it's idempotent:
npx get-shit-done-cc@latest
Containers or Docker? Set CLAUDE_CONFIG_DIR before installing to avoid tilde-expansion issues:
CLAUDE_CONFIG_DIR=/home/youruser/.claude npx get-shit-done-cc --global
