* test(#2666): add regression + docs-parity guards for code-review file scoper The Tier-2 SUMMARY.md extractor dropped every repository-root file (no `/`) and every extensionless build file (Dockerfile/Makefile/etc.) via an AND-joined predicate. Adds behavioral tests against the pure-function mirror plus docs-parity structural guards that bind the shipped workflow .md to the fix. RED: the docs-parity guards fail against the pre-fix shipped predicate. * fix(#2666): accept root-level + extensionless build files in code-review scope; intersect-and-warn Two coordinated edits to gsd-core/workflows/code-review.md compute_file_scope: (A) Tier-2 SUMMARY extractor: replace the AND-joined predicate `/\\//.test(raw) && /\\.[A-Za-z0-9]+$/.test(raw)` (which required BOTH a directory separator AND a trailing extension, silently dropping every root-level file and every extensionless build file) with a relaxed predicate that accepts any path with a trailing extension OR a known extensionless build basename (Dockerfile/Containerfile/Makefile/Justfile/Procfile). (B) Tier-3: convert the eq-zero git-diff gate into an intersect-and-warn — whenever a reliable diff base is available, cross-check the SUMMARY scope against `git diff --name-only` and warn about (then add) any changed files the SUMMARY extractor did not surface. Portable (bash 3.2, no associative arrays) so a partial SUMMARY result can no longer silently ship an incomplete review scope. * chore(#2666): changeset fragment * fix(#2666): use exact whole-line matching (grep -Fxq) in Tier-3 cross-check Adversarial review found the unanchored `case "$IN_SCOPE" in *"$file"$\\n*` substring membership test would false-match: a root-level `Dockerfile` in the diff substring-matches an already-scoped `docker/Dockerfile`, silently skipping it — reintroducing the exact class of silent-scope-loss bug this PR fixes. Switch to `grep -Fxq` (exact whole-line match). Add docs-parity guard for exact matching + the basename-collision regression. * fix(#2666): resolve gsd-test failures — paraphrase predicate in comment, ack code-review.md growth gsd-test caught 3 issues on 7469c3f22: 1. The docs-parity guard fired on the .md COMMENT which restated the buggy predicate verbatim — paraphrase the comment so it no longer contains the exact string the guard detects. 2. Cascade subtest failure from #1. 3. emitted-attribution: code-review.md grew 2814 bytes — acknowledge the deliberate #2666 growth in tests/emitted-drift-ack.json. * chore(#2666): backfill changeset PR number 2895 --------- Co-authored-by: Test <test@example.com>
GSD Core
Git. Ship. Done.

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.
