* fix(#2408): fold colliding phase statuses + add W023 collision warning Two coupled bugs from #2408: 1. cmdStats last-write-wins status (src/commands.cts:1610-1618): when two on-disk phase directories normalize to the same phase key (e.g. `05-real/` and `05-real-stray/`), the directory-scan merge overwrote `status` with whatever the *current* directory in scan order computed, discarding `existing?.status` entirely. fs.readdirSync order is not stable across platforms, so /gsd-stats could silently report `Not Started` for a phase that is actually `Complete`. Plan/summary counts were already additively merged; only `status` was wrong. Fix: introduced a `foldPhaseStatus(a, b)` helper that returns whichever status is further along the precedence ladder `Complete > Needs Review > Executed > In Progress > Planned > Not Started` (with `Pending` and unrecognized statuses ranked after). The merge site now calls `existing ? foldPhaseStatus(existing.status, status) : status`. The fold is commutative, so the result is identical regardless of read order. 2. cmdValidateHealth had no collision-detection pass (src/verify.cts): codes W001-W022 cover every condition except normalized-key collisions, so an operator got zero signal that anything was wrong. Fix: added W023 — groups phaseDirEntries by their normalized phase key (via the existing normalizePhaseName + extractPhaseToken helpers from phase-id.cjs — same normalization cmdStats uses) and emits a warning for any group with ≥2 dirs. The warning names the normalized key, both directory names (sorted by comparePhaseNum for stable output), and each directory's independently-computed status (via determinePhaseStatus imported from commands.cjs). Wording is deliberately neutral — never guesses which directory is the real one. The optional --repair path from the issue is intentionally NOT implemented in this PR (the issue marked it lower priority and acceptance criterion 4 is vacuously satisfied by omission). Triage correction applied: the issue proposed W022, but that code is already in use for config.json model-tier validation (src/verify.cts :1372-1391). The next free code is W023, used here. Tests: - tests/commands.test.cjs: integration test that 05-real/ (Complete) + 05-real-stray/ (empty/Not Started) collide and stats reports the merged phase as Complete regardless of read order; plus a direct unit test of foldPhaseStatus asserting commutativity + correct precedence for every status pair + correct handling of unrecognized statuses. - tests/health-validation.test.cjs: integration test that W023 fires on the collision naming both dirs + their statuses (and uses neutral wording), plus a negative test that no W023 fires when only one dir exists per key. References: #2408; reporter's three-layer triage + acceptance criteria; triage correction that W022 is already in use (model-tier validation). * chore(#2408): backfill pr:2461 in .changeset/graceful-koalas-forage.md
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.
