* test(#4667): add failing-first coverage for the codex @-include rewrite Behavioral end-to-end: a real in-process install(true,'codex') into a temp CODEX_HOME must leave zero @~/.claude includes in GSD-owned .md artifacts, rewrite the issue's own example include to @~/.codex/, keep the deliberate _GSD_RUNTIME_ROOT .claude fallback chains byte-identical, and stay idempotent across a reinstall (no doubled prefix). All four are RED until the installer grows the manifest-scoped rewrite pass. * fix(#4667): rewrite codex @ includes to the codex install root Codex-installed agents and commands kept @~/.claude/gsd-core/... (and @/Users/trekkie/.claude/gsd-core/...) include references pointing into the Claude install: silent wrong-copy reads on dual-runtime machines at divergent versions, missing files on codex-only ones. Several emitters bypass the per-runtime converters, so the per-emitter fixes since #570 rotted. Adds a manifest-scoped rewrite pass in install() beside the leak scanner: for codex, every manifest-tracked .md/.toml artifact has the @-include forms rewritten to the codex root. The pass matches the exact include literal only — the _GSD_RUNTIME_ROOT/$PREFERRED_CONFIG_DIR fallback chains, prose .claude mentions, and CHANGELOG.md are untouched — and runs before the scanner, which remains the verification backstop for anything a future emitter introduces. * test(#4667): cover the HOME-anchored include form and sync the pass comment Adds behavioral coverage for the second rewrite literal (@$HOME/.claude/gsd-core/ -> @$HOME/.codex/gsd-core/) via the plan-review-convergence command, and corrects the pass's comment: the agent .tomls are generated after it and prefix themselves, so the .toml branch of the rewrite is inert by design. * test(#4667): baseline the offline upgrade against the deployed tree (sanctioned) * chore(#4667): backfill changeset PR number (4858) * test(#4667): sandbox the install home in the include-rewrite tests (#3712 guard) * test(#4667): install via subprocess with an isolated env in the include-rewrite tests --------- 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

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.
