* fix(#3374): phase.complete stops harvesting stale body stopped_at Variant A: cmdPhaseComplete's adapter calls syncStateFrontmatter directly (deliberately - STATE.md commits atomically with ROADMAP/REQUIREMENTS), which also bypassed the #948/#1230 preservation pass every RMW write gets. A stale body 'Stopped at:' line then silently clobbered a fresher frontmatter stopped_at on every phase completion, with warnings: []. Three layers close it without reversing #3517's refresh expectation: - completePhaseCore now refreshes the body continuity line it implies ('Phase N complete, ready to plan Phase N+1'; ADR-2207 phrasing on the last phase), session-scoped via the new stateReplaceFieldInSession seam so a decoy bold Stopped-at line in an unrelated section cannot absorb the refresh. Replace-only - a layout with no session line keeps its shape and its frontmatter value survives via the preservation delta. - the RMW post-sync preservation chunk (snapshots + table-driven applyStatePreservation + #2736 re-assert, full bodyDeltas wired) is extracted into the shared applyPostSyncPreservation helper; the phase.complete adapter and writeStateMd (milestone complete / state sync - the gap the closed PR #3442 review flagged) now run it too. - cmdStateRecordSession pushed 'Stopped At' onto updated[] on any label MATCH, including a value already on disk - reporting a write that never changed a byte. It now reports only on real change, and the match is tracked separately so an identical value does not arm the #944 DWIM section rewrite (which would reset an executor-authored resume file to None). * docs(#3374): backfill changeset pr field to 3491 * fix(#3374): drop the writeStateMd preservation pass - state sync's #905 contract is body-wins CI on this PR caught what the closed PR #3442 review's MAJOR remediation option (a) would have broken: state sync's #905 contract ('body annotation beats existing frontmatter when both are present') is the opposite by design - sync exists to re-derive frontmatter from the body. A blanket applyStatePreservation pass on writeStateMd re-locked stale frontmatter (current_phase 3 over the body's 5) on every sync. Take the review's sanctioned option (b) instead: the scope claim is accurate (phase.complete only) and the milestone complete / state sync exposure is tracked as follow-up issue #3492. --------- Co-authored-by: sim <sim@local>
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.
