test.yml had no paths filter and the ci-test-scope classifier treated docs/ and every .github/workflows/* as code_changed, so documentation edits and product-irrelevant automation tweaks still spun up the full Linux/Windows/macOS matrix. Narrow the heavy matrix to changes that can actually affect the product or the test pipeline. - ci-test-scope.cjs: drop docs/ from code_changed (docs-only -> full skip; the required-tests fan-in still reports green). Add src/ to code_changed (it was missing -> a source-only PR previously skipped all tests). Add INERT_WORKFLOWS allowlist + isInertCi() + an "inert CI" rule, and a product_changed output that gates the heavy test/coverage jobs. Fail-safe: any workflow not on the inert allowlist defaults to the full matrix. A module-load assertion throws if a PROTECTED_WORKFLOWS entry (test/install-smoke/mutation/security-scan/release) is ever added to the inert set, so a weakening edit fails CI loudly. - test.yml: keep the static 3-lane matrix (so the H1 shell-policy linter can still statically verify the Windows lane), gate test/coverage on product_changed, add a lightweight ubuntu-only test-inert job, and branch the required-tests fan-in on product_changed. - docs-required.yml: run docs-parity-live-registry (gated on docs/ changes) so pure-docs PRs still catch live-registry drift without the matrix. - tests: cover docs-only, inert-only, src/, pipeline, unknown-workflow fail-safe, mixed escalation, the code_changed=false -> no-lanes invariant, and protected- workflow tamper-evidence.

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, Gemini 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, Gemini 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, Gemini 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 your first project:
/gsd-new-project

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.
