* refactor(#1059): phase 5f-1 — extract standalone hook-surface writers into a module Extract the structurally-isolated hook-surface writer functions (cline/cursor/ copilot/codex-hooks-json + buildHookCommand + atomicWriteFileSync + node/bash runner resolvers) out of bin/install.js into a new src/runtime-hooks-surface.cts module (-693 LOC from install.js). Behavior-preserving: install.js requires + re-exports the moved functions (module.exports surface preserved); no descriptor reads, no behavior change. Prerequisite for the descriptor-drive (5f-2), mirroring ADR-3660's artifactLayout extract→drive split. Review caught + fixed 3 coupling issues: (HIGH) the module's atomicWriteFileSync dropped the shared __atomicWrittenTmps temp-tracking → now ONE shared set (module owns it, install.js aliases it, both cleanups read it); (drift) buildHookCommand called resolveNodeRunner(opts) vs the original resolveNodeRunner() → reverted; two source-grep tests (workflow-guard, sh-hook-paths) that scanned install.js for the moved functions → made behavioral/non-vacuous; duplicate runner resolvers consolidated. Settings-json hook block (~648 LOC) deferred to 5f-1b; descriptor-drive to 5f-2. New-module checklist done. ~62 hook test files green; gsd-test 17592/0. Closes #1059 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * chore(#1059): reconcile CLI Modules count after merging next (uat-predicate) Merging current next (which added uat-predicate.cjs via #247) alongside this branch's runtime-hooks-surface.cjs put the filesystem at 107 bin/lib modules, but both sides had independently bumped the INVENTORY headline 105→106 so the merge under-counted. Set "CLI Modules (107 shipped)" + regenerate INVENTORY-MANIFEST.json. Both module rows already present. Fixes inventory-counts.test.cjs (the only CI red).

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.
