gsd-test's build leg runs the full 'npm run build' (which regenerates capability-registry.cjs, loop-host-contract.cjs, package-identity.cjs, etc.), so committed-freshness guards that lived in the unit suite were masked there: gsd-test passed a stale-commit that CI's shard-1/3 test then red-flagged (caught live on PR #1998). The mandated pre-push gate was green on a commit CI correctly flagged. Move the committed-state --check guards into a new 'lint:generated-sync' script wired into lint:ci (the single orchestrated entry point the lint-tests CI job already runs on a build:lib-only tree, so the committed artifacts are checked without regeneration). gsd-test no longer contains these guards, so it can no longer mask them. - package.json: add lint:generated-sync (7 generators --check); wire into lint:ci. - generate-package-identity.cjs: add --check mode (was the only generator without it); no-arg behaviour unchanged (still writes, as build expects). - Remove the committed-freshness guards from the unit suite, keeping all behavioral/structural tests: - capability-registry.test.cjs: drop the --check describe. - loop-host-contract.test.cjs: drop the committed-file staleness test (keep the normalizeLineEndings unit test). - capability-matrix-sync.test.cjs: drop --check + byte-for-byte (keep the architectural content invariants: every cap appears, security ship:pre). - issue-844-manifest-version-sync.test.cjs: drop describe D (--check). - issue-498-package-identity.test.cjs: drop the drift-check test (keep behavioral module-export tests); drop the now-unused render import and its allow-test-rule exemption (allowlist ratcheted 175 -> 174).
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, Gemini 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, Gemini 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, Gemini 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 your first project:
/gsd-new-project

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.
