* fix(#2778): exempt intentionally-absent paths from the glossary gate check-glossary-refs asserts that every backticked tests/ token in CONTEXT.md resolves on disk. tests/emitted-drift-ack.json (ADR-2719 section 3) is absent on a healthy next BY DESIGN — it appears only inside a PR that needs it, which is what makes touching it the alarm. It passed before only by accident of backtick pairing: CONTEXT.md's RULESET entries are themselves backtick-wrapped and contain backticks, so the token happened to fall outside a code span. Any edit that shifted the parity exposed it. A gate that passes by luck is not passing. The exemption is exact, not a prefix hole: a sibling missing tests/ path still fails, and a test locks that. * feat(#2778): make the size-ratchet failure name its own remedy The growth branch stated a requirement and withheld the means of satisfying it: no ack file named, no schema, no key format, and no do-not-regenerate line — so the likeliest guess was to hunt for a baseline that #2724 deleted. Observed live on #2543. All remediation now comes from one frozen REMEDIATION export whose example document is rendered from ACK_VERSION, so the taught schema cannot drift from the schema parseAck accepts. A round-trip test feeds the printed document back through parseAck. The report is now built as a typed IR (buildReport) that formatReport renders, so tests assert on structure rather than prose, per CONTRIBUTING.md's raw-text-matching rule. Two defects found and fixed inline while building: - diffEmitted's validation early-return omitted newFileCapExceeded while formatReport reads its length, so the branch that reports a failed git diff threw a TypeError instead of naming the problem. - Printing one complete ack document per failing branch made each read as the whole file, so pasting the second over the first silently lost an acknowledgment. One document now covers the whole report. Closes #2778 * chore(#2778): backfill changeset pr number to 2780
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
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.
