* feat(#787): elevate Cline — .clinerules/ dir form, PreToolUse hook, AGENTS.md Migrate the installer's Cline output from a single-file .clinerules to the .clinerules/ directory form (.clinerules/gsd.md), which is the prerequisite for Cline's v3.36 hooks (a path cannot be both a file and a directory). Add a .clinerules/hooks/PreToolUse lifecycle hook implementing Cline's JSON stdin -> {cancel,errorMessage,contextModification} protocol; it guards .planning/ artifacts and fails open. On global installs, merge GSD instructions into the cross-tool ~/.agents/AGENTS.md target (marker-delimited, merge-safe). A legacy single-file .clinerules is migrated in place; --uninstall removes the new artifacts and strips the AGENTS.md GSD block. Also fixes the uninstall targetDir for Cline local installs (it pointed at ./.cline instead of the project root) and re-runs writeManifest after the Cline artifacts are written so they are hash-tracked. Self-contained: implemented independently of the #782 Cline skills work. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#787): address review findings - Scope PreToolUse hook path-walk to PATH_KEY fields only (eliminates false positive when doc body content mentions .planning/) - Use lstatSync + isSymbolicLink() for migration guard so GSD never writes through a user's symlinked .clinerules into an external directory - Add regression tests for both cases Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * chore(#787): set changeset pr: 803 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>
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, 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, 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, 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.
