* feat(#4422): block merging into next/main while the base branch's Tests run is red Adds a next-health job to test.yml that checks the base branch's own last push-triggered Tests run via the GitHub API and fails the existing "Required tests" required check when it's red, with a maintainer-applied "fix-next" label as the explicit escape hatch for the fix-forward PR itself. No branch-protection config change needed — it rides the already-required check. The job is deliberately not gated behind preflight, same reasoning as the changes job: a compute-free API read has nothing to save by waiting. Documents the fix-next label in CONTRIBUTING.md and adds a property test locking the CLEAN/RED/INDETERMINATE classification's iff-relationship. This closes the second half of the 2026-09-06 RCA: three unrelated PRs merged on top of an already-broken next before anyone noticed it was red. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix: close two zero-margin CI timing gaps found while verifying #4422 Discovered while watching this branch's own CI, root-caused via /diagnose rather than dismissed as Windows flakiness: 1. tests/gsd-check-update-worker-atomic-cache.test.cjs's outer timeout (15000ms) exactly matched the inner npm-view timeout the worker wraps (NPM_VIEW_TIMEOUT_MS, gsd-core/bin/check-latest-version.cjs). A slow registry response raced two SIGKILLs at the same instant, killing the worker before it could catch its own timeout and degrade gracefully. Windows's shell-wrapped npm subprocess made the race lose more often there, but the zero margin was platform-agnostic. Fixed by giving the test real headroom (+10s) beyond the named constant it wraps, plus an invariant test so the two values can't silently collide again. 2. scripts/run-tests.cjs's per-chunk weight budget (MAX_FILES_PER_CHUNK) let a Windows full-matrix chunk that was well under budget by the Linux/macOS-calibrated weight table (~32/60 units) still exceed the 600s wall-clock backstop — codex-config.test.cjs's genuinely-measured weight (17.87) doesn't transfer 1:1 to Windows's slower install/ subprocess overhead. Windows now gets its own lower cap (40 vs 60).

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.
