* feat(#2162): opt-in compact GSD-state format for the statusline New statusline.state_format config, enum full|compact (default full — existing rendering untouched). "compact" renders the state segment as "<version> · P<phase>/<total> · <status>", e.g. "v1.12 · P7/12 · executing" — dropping the milestone name and progress bar (the two biggest width costs) and collapsing narrative statuses to a single keyword. Per the #2162 approval conditions, the keyword set is the canonical vocabulary from normalizeStateStatus() in state-document.cjs (discussing/planning/executing/verifying/completed/paused) — no parallel hand-rolled list, so the vocabularies can't drift — and the canonical stuck state "paused" renders uppercase as PAUSED (no new "blocked" lifecycle state). Statuses the normalizer passes through unrecognized fall back to their first word capped at 16 chars. Lifecycle scenes preserved: active_phase wins over the body phase number, milestone completion renders "complete", idle-with-next-action renders "next <action> <phases>".

Gate is now !s.activePhase. The phaseNum-only test now expects 'complete' and cross-checks the full renderer; a parity test feeds identical inputs to both renderers. Re-review Minor: shortGsdStatus gets fast-check property coverage (totality, canonical fixed points, separator safety, fallback shape). Golden fixtures regenerated for the hook byte change.

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.
