* test(#2640): add regression for state_updated false positive + stale progress Three cases: (1) state_updated reflects actual content change, not just file existence; (2) progress.total_phases resync'd even when the body lacks 'Total Phases:' (the no-op guard was skipping syncStateFrontmatter); (3) state_updated is false when STATE.md doesn't exist. * fix(#2640): report truthful state_updated + force frontmatter resync Two defects in cmdPhaseRemove: 1. state_updated was fs.existsSync(statePath) — trivially true, since the file existed before and readModifyWriteStateMd never deletes it. Now captures the boolean return from readModifyWriteStateMd (changed from void to boolean: true when content was written, false on no-op). 2. progress.* frontmatter stayed stale when the body lacked 'Total Phases:' or 'of N' — readModifyWriteStateMd's no-op guard (#948) skipped syncStateFrontmatter when the body transform was unchanged. Now the transform forces a body diff when a phase was actually removed, so the guard passes and syncStateFrontmatter rebuilds progress.* from the post-deletion disk/ROADMAP state. * fix(#2640): address review — gate forced-diff on targetDir, strengthen assertions Two MAJOR findings from isolated adversarial review: 1. Forced-diff injected a spurious 'Total Phases:' line even when no directory was removed (targetDir === null). Now gated on targetDir !== null. 2. Test #2 asserted 'not 3' instead of '2' — would pass for any wrong count. Now asserts exact value. Test #1 strengthened to assert body Total Phases and frontmatter total_phases both equal 1. * chore(#2640): add changeset fragment * chore(#2640): backfill changeset PR number 2974 --------- 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.
