* test(#3144): bound the git/worktree cluster onto the process seam Migrates 180 unbounded sync spawn sites across 19 files. Every previously unbounded call now carries an explicit timeout with a comment giving the number and why. The migration is not a callee swap. execSync and execFileSync throw on a non-zero exit and the seam never does, so each site was classified first: sites that rely on the throw route to gitOrThrow, and sites that already read .status to detect an EXPECTED non-zero -- an intended cherry-pick conflict, a rev-parse outside a repo driving a skip -- route to the never-throwing runGit instead, which would otherwise throw on exactly the exit being probed for. Two same-named git() helpers in worktree-cleanup.test.cjs have different return contracts, one trimmed and one raw; both are preserved rather than unified. Collapses five hand-rolled throw wrappers onto one throwIfFailed in git-fixture.cjs, which gitOrThrow now also uses so the shape cannot drift. Allowlist drops 139 to 120; BASELINE lowered to match. * test(#3144): fix pre-PR review findings Documents throwIfFailed in the CONTEXT.md glossary and CONTRIBUTING.md -- it became the shared throw mechanism without either doc naming it. Routes the sixth and seventh hand-rolled copies of the throw shape through throwIfFailed (worktree-baseref-install, worktree-safety-reap); the first consolidation missed both. Converts ci-rebase-check's 8 fixture-setup calls from unchecked runGit to gitOrThrow so a failed setup step aborts where it fails rather than surfacing later as a confusing failure against the wrong subject. Adds 12 direct unit tests for throwIfFailed, which until now was only exercised transitively. Splits verify.test.cjs's non-git grep/sed bound off GIT_TIMEOUT_MS. --------- Co-authored-by: sim <sim@local>
GSD Core
Git. Ship. Done.
English · Português · 简体中文 · 日本語 · 한국어
A light-weight meta-prompting, context engineering, and spec-driven development system for Claude Code, OpenCode, Antigravity CLI, Kimi CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more.
What is GSD Core
GSD Core is a context-engineering and spec-driven development framework that drives AI coding agents (Claude Code, Codex, Antigravity CLI, Kimi CLI, Copilot, Cursor, and more) through a disciplined phase loop. It solves context rot — the quality degradation that accumulates as an AI fills its context window — by running all heavy research, planning, and execution work in fresh-context subagents while keeping your main session lean.
How it works
Each milestone repeats the same five-step loop, one phase at a time:
- Discuss — capture implementation decisions before anything is planned
- Plan — research, decompose, and verify the plan fits a fresh context window
- Execute — run plans in parallel waves; each executor starts with a clean 200k-token context
- Verify — walk through what was built; diagnose and fix before declaring done
- Ship — create the PR, archive the phase, repeat for the next one
Quickstart
npx @opengsd/gsd-core@latest
The installer prompts for your runtime (Claude Code, OpenCode, Antigravity CLI, Kimi CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more) and whether to install globally or locally. The installer is required for cross-runtime compatibility — do not copy files from agents/ or commands/ directly.
On another runtime or without Node.js? See Install on your runtime.
Once installed, start a new project or onboard an existing repo:
/gsd-new-project # greenfield project
/gsd-onboard # existing codebase
New here? Follow Your first project for a guided walkthrough from install to first shipped phase, or Onboarding an existing codebase for brownfield setup.

Why it works
Most AI-coding setups fail at scale because context bloat silently degrades output quality, there is no shared memory between sessions, and nothing verifies that code actually works. GSD Core solves all three: heavy work runs in fresh subagents, structured artifacts like STATE.md and CONTEXT.md survive session boundaries, and the verify step walks through what was built and generates fix plans before a phase is declared done. See docs/explanation/context-engineering.md for the full reasoning.
