* enhance(#4377): opt-in project-relative includes for local installs A local install wrote the includes that point at GSD's own files as absolute paths — whatever the installer resolved at install time. For one checkout that is invisible. Across git worktrees it is not: each worktree gets its own .claude/ copy, but all of them point back at the checkout that ran the installer, so a worktree runs its own gsd-tools.cjs while reading workflow prose from a different checkout. Update that one checkout and every other worktree is running new instructions against an old engine, with nothing to stage the update with. --relative-includes (or GSD_RELATIVE_INCLUDES=1) makes a local install emit `@.claude/gsd-core/...`. Opt-in, and staying opt-in: absolute works for a single checkout, which is most people, and flipping the default would change every existing local install to solve a problem those users do not have. The prefix is the runtime's own localConfigDir descriptor value, never a literal — the same value resolveScope joins onto the cwd to produce the install target, and the same one the rewrite engine already uses for its ./.claude/ -> ./<dir>/ substitutions. Copilot and Antigravity have shipped this shape for local installs since they were added, with hardcoded .github/ and .agents/; this is that behavior, derived rather than written down. Six seams compute a path prefix and all six had to be threaded, which is why the opt-in travels through the environment the way --portable-hooks already does: one variable they all read cannot fall out of sync the way six signatures can. The launcher shim deliberately keeps its ABSOLUTE fallbacks. It probes gsd-tools through ${CLAUDE_CONFIG_DIR:-$HOME/.claude} and one such default per runtime; those are shell word expansions, not includes, and a relative value there resolves against the shell's cwd rather than the project. Trading an include that points at the wrong checkout for a path that points at nothing is not a fix. All three rewrite paths mask ${VAR:-default} spans before substituting and restore them after, and the mask only runs when the prefix is relative, so an absolute install is byte-for-byte unchanged. Every unexpressible case falls back to absolute: no opt-in, a global install, a missing dir name, the configHome.kind === 'none' sentinel, an absolute descriptor value, or one climbing out of the project with '..'. * chore(#4377): add changeset for project-relative local includes * fix(#4377): compare against POSIX-normalized roots in the install e2e arms The emitted prefix is POSIX-normalized by design — it is substituted into markdown @-references, which use forward slashes universally, so a backslash would leak into shipped content (#1615). The e2e arms compared against the raw temp root, which on Windows is `D:\a\...` and appears in no emitted file. That reddened the control arm on the windows shard, and it was worse than a red: the negative arm ("nothing references the checkout") was passing VACUOUSLY there, because a string that cannot occur is trivially absent. Both now go through the same normalization, so the Windows lane asserts what the Linux lane does. * fix(#4377): tolerate a resolved temp root, and make the e2e diff self-diagnosing Two changes, one confirmed and one to stop guessing. Confirmed: the emitted content carries the RESOLVED root, not the spelling mkdtemp handed back. Reproduced on Linux with a symlinked install root — 236 emitted files carry the realpath, zero carry the link path. macOS has this structurally, since /var is a symlink to /private/var. Comparisons now go through both spellings, or the negative arms pass vacuously: "nothing references the checkout" is trivially true when the string being searched for cannot occur. Not confirmed: the macOS shard reported ~every workflow file differing in the "differ ONLY" arm while the five arms around it passed, and the assertion printed a list of filenames — which says a difference exists somewhere across 236 files and leaves the reader to guess which bytes. I cannot reproduce that platform locally, and guessing turns one CI round-trip into four. The assertion now reports the first divergence as text: the file, the byte offset, and a bounded window of both sides. * fix(#4377): strip the longest root spelling first in the install e2e diff The macOS failure was my test corrupting its own comparison, not a product defect. /var/folders/…/X is a SUBSTRING of /private/var/folders/…/X, so stripping the unresolved spelling first matched inside the resolved one and left the /private prefix glued to what followed: @/private/var/…/X/.claude/gsd-core/… -> @/private.claude/gsd-core/… a string present in neither install, which is why all 236 files "differed". Sorting the spellings longest-first consumes the whole occurrence, and the short form then has nothing left to match. Proven in isolation on the exact macOS shapes: short-first yields @/private.claude/…, longest-first yields @.claude/…. The self-diagnosing assertion added in the previous commit is what found this — it named the file, the byte offset, and printed both sides, so the corrupted string was visible rather than inferred from a list of 236 filenames. Keeping it. * fix(#4377): address review findings * test(#4377): scan nested shell defaults without regex backtracking * fix(#4377): close relative include review gaps * fix(#4377): preserve root-target runtime includes * fix(#4377): guard project-root relative includes * test(#4377): normalize Cline fallback roots * fix(#4377): persist relative include style --------- Co-authored-by: Tom Boucher <trekkie@nomorestars.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, 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.
