Closes the issue's explicit acceptance criterion: "health.md's tables are generated rather than hand-maintained, closing the 16-vs-30+ documentation gap structurally." The published roster listed 16 codes against 30+ actually emitted; W010-W017 and W020-W023 had never been documented. Adds description/repairable as static fields on Rule (health-diagnostic-types.cts) — generation needs a fixed, human-readable summary per code, distinct from the dynamic per-instance Diagnostic.message a rule's check() produces. repairable is true only when --repair will actually apply the remedy: false for ADVISE-only rules AND for DESTRUCTIVE-risk rules (regenerateState/resetConfig), which are described but never auto-applied — matches verify.cts's diagnosticToIssueEntry semantics exactly, after fixing E004/E005's static field to agree with it (both were wrongly true, an inconsistency caught during this same commit's own review, not left for later). New scripts/gen-health-docs.cjs (--write/--check, wired into lint:generated-sync) regenerates the two tagged table regions in gsd-core/workflows/health.md from RULES (31 rules) plus the 3 pre-checks that stay outside the rule table by design (E001, E010, I010) plus a small static Effect/Risk lookup for the 6 real repair actions — including addAiIntegrationPhaseKey, live in code since an earlier phase but never documented until now. 34 error-code rows, 6 repair-action rows. The table's old "grep verify.cts for the next free number" footnote is rewritten to point at the rule table and its lint guard instead.
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.
