* test(#3143): add no-unbounded-spawn guard and throw-preserving git fixture Adds the ESLint rule local/no-unbounded-spawn, wired into the tests/**/*.cjs block, plus an allowlist that only ratchets down: a listed file with zero violations reports its own entry as stale. The rule resolves renamed destructures and chained requires rather than matching literal callee names -- both forms exist in the suite today and a name-only matcher leaves them permanently invisible. It resolves an options object held in a single-write const, which is what keeps process-seam.cjs, the bounded reference implementation, from flagging itself. timeout: 0 and anything above the 600000ms ceiling are rejected as only nominally bounded. Adds tests/helpers/git-fixture.cjs so a migrated execSync call site keeps its throw-on-non-zero contract; process-seam.cjs is unchanged. * test(#3143): prove the allowlist guards can actually fail Extracts the D4/D6/D7/D8 checks into pure helpers and drives each against a synthetic fixture carrying an injected violation. Without this the suite only proved that today's clean data passes, which a deleted check would also satisfy. * fix(#3143): close two ceiling and alias escapes found in review Nested arithmetic bypassed the ceiling entirely: the numeric evaluator only resolved a flat literal, so `timeout: 60 * 60 * 1000` (3600000ms, six times the ceiling) fell through to trusted and reported nothing. The evaluator now recurses through arithmetic and unary signs with a depth cap. Alias resolution was traversal-order dependent, not scope dependent: a call textually above its own require destructure saw an empty alias map and reported clean. The map is now built in a Program pre-pass. Also: an explicit timeoutMs:undefined no longer overwrites the git fixture default via spread, adds the missing seam-routed rule test, and de-duplicates the repeated try/catch in the fixture tests. --------- 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

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.
