Migrate the STATE.md write path inside cmdPhaseComplete (phase.cts) onto the STATE.md Transition Module substrate (ADR-1769, epic #1769). - Add {kind: 'completePhase'} to StateTransitionIntent + completePhaseCore in src/state-transition.cts. Pure body field mutations (Current Phase shape/name, Status, Current Plan, Last Activity + Description, Completed/Total Phases + Progress percent), consulting the field-classification table for touched keys. Roadmap progress injected via a new optional deps.roadmapProvider. - Collapse the ~90-line inline STATE.md transform in cmdPhaseComplete to a transitionCore dispatch. The adapter retains updatePerformanceMetricsSection (section table) + syncStateFrontmatter (disk-scan post-sync) and the multi-file atomic transaction (STATE is committed with ROADMAP/REQUIREMENTS, so readModifyWriteStateMd is not used here). - deriveProgressFromRoadmap/clampPercent/stateReplaceFieldWithFallback move from the phase.cts call site into the pure core (no circular dep: phase-lifecycle and state-document don't import state.cts). - Characterization tests in tests/state-transition.test.cjs pin the field updates, roadmap progress derivation, #1255 frontmatter parity, and the 'Phase:' fallback. All 44 transition + 193 phase tests pass. No user-visible behavior change. cmdPhaseComplete CLI output and 'phase complete' behavior unchanged. Closes #1784
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, 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, Gemini 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, Gemini 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 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.
