* test(#3133): global Claude @-references must resolve on tilde, not $HOME Regression for #3133: on a global Claude install, _applyRuntimeRewrites rewrites @~/.claude/... -> @$HOME/.claude/..., but Claude Code does not expand $HOME in @-file references, so the include silently resolves to nothing and the skill loads an empty execution_context. Rows 1/2/6/9 fail RED on next; rows 3-5/7-8 guard #1284 (shell $HOME), local redirect, #3503 (no homedir leak), and non-Claude isolation. * fix(#3133): keep global Claude @-references on tilde, not $HOME On a global Claude install, _applyRuntimeRewrites rewrote every @~/.claude/ include to @$HOME/.claude/ because computePathPrefix returns the $HOME form for shell-context correctness (#1284: ~ does not expand inside double quotes). Claude Code does not expand $HOME in @-file references, so the rewritten include silently resolved to nothing and skills loaded an empty execution_context. Add a normalization pass in the claude case: when the prefix is the $HOME (global) form, restore @$HOME/.claude/ -> @~/.claude/ (the form Claude expands and the shipped tarball uses). Shell contexts keep $HOME; local installs (absolute prefix) are unaffected; computePathPrefix is untouched (all its tests stay green). * test(#3133): fix row 9 assertion — drop end-of-string anchor Row 9's regex used $ (end-of-string) but a realistic @-ref line ends with a newline, so the anchor could not match. The fix under test produces the correct @~/.claude/gsd-core/references/ui-brand.md tail; only the assertion was wrong. Drop the anchor and assert the tail + no @$HOME. * docs(#3133): add changeset * docs(#3133): backfill changeset PR number (3393) --------- 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.
