* enhance(#3085): add Grep to allowed-tools for 21 skills
29 of 71 skills omit Grep from allowed-tools, forcing Bash grep for
structured search instead of the dedicated tool. Adds Grep to the
21-skill subset confirmed safe in prior review (excludes the 6
gsd-ns-* dispatchers, gsd-help, and gsd-surface, which have no
plausible structured-search need).
Hand-edits commands/gsd/*.md only; skills/*/SKILL.md is regenerated
via `npm run gen:plugin-skills` from that source. Updates the one
hardcoded copilot-install test assertion affected by gsd-health's
new tool order.
* chore(#3085): backfill changeset PR number

* test(#2618): assert the Needs clause on the structured field, not the path-length-dependent bullet
The bullet embeds the todo file's ABSOLUTE path, so its total length
varies by runner tmpdir: on macOS CI, /private/var/folders/… plus the
test harness's gsd-test-run-* wrapper pushed the full bullet to 244
chars — past renderPendingTodoBullet's intended 240-char cap, whose
documented first degradation step drops the Needs clause. The product
behavior is correct (#2618 design); the assertion was runner-dependent.
The extraction is now pinned on json.todos[0].needs; the rendered-bullet
shape stays covered by the path-independent title assertion and the
renderer's own unit rows.
Found blocking #4186's CI on the macOS shard (test landed 30 minutes
earlier in b7406b293f / PR #4384).

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.
