* enhance(#2573): stamp STATE.md with its commit and surface a commit-age freshness hint Adds a `state_head` stamp to STATE.md and derives a tri-state commit-age freshness proxy (state_commits_behind / state_commit_stale) through state.cjs's readStateHeadFreshness, surfaced on smart-entry signals and as health W024. The proxy is advisory: classify() deliberately does NOT consume it (ADR-1787 locks the classification/routing boundary — a signal, not a route). Composes with #3099 and #1882 (both merged to next after this branch): the commit-age proxy reads `state_head` while the LAST_ACTIVITY_UNPARSEABLE diagnostic reads `last_activity` — two different fields, not "two staleness signals on one field." A new regression test asserts a STATE.md carrying both an unparseable last_activity AND a valid state_head resolves each independently (diagnostic fires once; freshness reads state_head, commits_behind 0). Rebased onto next (flattened): resolved the add/add conflicts in src/smart-entry.cts (kept both the #2573 freshness import/derivation and the #3099 diagnostic import/call) and tests/smart-entry.unit.test.cjs (kept both describe blocks). Drift-ack for health.md's W024 row is unchanged (12348 B). Tests: smart-entry 62, state/state-transition/health/verify 639, all pass. * chore(#2573): allowlist health-validation test in the prompt-injection scan The scanner's `exec('` code-execution pattern matches the benign `re.exec('<phase-id>')` RegExp method calls in the phase-ID grammar tests (pre-existing: 16 such calls on next, this PR adds none). The file entered the diff-mode scan's changed-file set only because #2573's W024 state_head assertions touch it. Allowlist it alongside the other test files that carry pattern-matching content as data (same DEFECT.PROMPT-INJECTION-SCAN-COLLISION class). Scanner self-test 38/0; diff scan 14 files, 0 findings.
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.
