* test(#2858): add class-extinction guard for shipped-script require boundary Every shipped scripts/**/*.cjs must be require-able using only shipped paths. The guard resolves the tarball file list via npm pack --dry-run --json (not a hardcoded list) and statically checks each require() call against the shipped set. A script requiring ../tests/** (which does not ship) is a violation. * fix(#2858): exclude gen-emitted-baseline.cjs from the npm tarball scripts/gen-emitted-baseline.cjs is repo-only CI tooling (CI workflows + test fixtures spawn it from a checkout). It requires three modules from tests/, which does not ship — so in a published install it is MODULE_NOT_FOUND at load time. Add a targeted files[] negation (!scripts/gen-emitted-baseline.cjs) so the script stays in the repo for CI use but does not ship. Other scripts that ship and are required by bin/install.js (build-hooks.js, fix-slash-commands.cjs, gen-capability-registry.cjs) are unaffected. The class-extinction guard test in tests/packaging-shipped-scripts-require-only-shipped.test.cjs ensures no shipped script can require outside the shipped tree going forward. * test(#2858): widen guard to .js + strip block comments (review fixes) Two findings from isolated adversarial review: 1. MAJOR: the guard only checked .cjs files, but scripts/build-hooks.js ships and is required by bin/install.js — a .js file with a broken require would bypass the guard. Widened filter to /\.(cjs|js)$/. 2. MODERATE: the static parser could false-positive on require() calls inside /* */ block comments or inline // comments. Now strips both before matching. * chore(#2858): add changeset fragment * chore(#2858): backfill changeset PR number 2968 * fix(#2858): add issue ref to allow-test-rule exemption (ADR-456) CI lint-tests caught: the allow-test-rule comment needs a 'see #NNN' ref per ADR-456. Added '(see #2858)' to the integration-test-input exemption. --------- 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.
