* test(#4699): add failing-first coverage for skipping complete phases in next_phase * fix(#4699): skip already-complete phases in the next_phase cascade Both next-phase scans selected the numerically lowest phase above N without consulting completion state, so completing a reopened phase persisted an already-[x] phase as STATE.md current_phase while roadmap.analyze correctly named the outstanding one (issue repro: completing 2 with phases 1 and 3 already [x] returned next_phase 03). The cascade collects the complete phase numbers from the roadmap checkboxes (milestone-scoped, comparePhaseNum-deduped) and skips them in both the disk scan and the roadmap scan; a [x] checkbox row and its heading sibling both name a phase that is never next. Heading-only and checkbox-less roadmaps behave exactly as before. * test(#4699): align the negative-control expectation with the disk spelling * test(#4699): pin the STATE.md persistence and the all-later-complete tail corner Review findings: the regression never asserted STATE.md current_phase (the issue's actual harm), and the all-later-phases-[x] corner (is_last_phase true, next_phase null) was unpinned. A changeset fragment is included. * docs(#4699): backfill changeset PR number * test(#4700): add failing-first coverage for the queued headless mine * fix(#4700): queue the headless mempalace mine and surface skipped captures The capture's mine ran in the foreground with no lock handling: MemPalace wraps every mine in a per-palace lock, so any concurrent writer (two phases finishing a stage at once, a git-hook refresh mining the same palace) made it exit 1 (MineAlreadyRunning) and the onError: skip step silently dropped the capture — unlost for CONTEXT/PLAN/SUMMARY files that can be re-filed, unrecoverable for execute:wave:post problem-fix pairs. The mine now queues via --daemon --background (MemPalace #2029: the daemon holds a job refused the lock and runs it when the holder exits), and the report step gains the queued and skipped outcomes per #4700's requirement that a skipped capture never stay silent. Option 2 (write_routing.cli) is unreleased at MemPalace 3.9.0; option 3 (retry) re-enters the same lock race — both declined in the PR body. * fix(#4700): queue the wave:post problems fragment's headless mine too The issue names the execute:wave:post problem-fix pair as the unrecoverable loss (no source file to re-file later); the capture-problems fragment's headless mine ran foreground like the capture capability's did. Same fix: --daemon --background, with the lock-deferral rationale inline. * docs(#4700): backfill changeset PR number * fix(#4682): register the stale-reverification part in the capability registry The new steps/ part is a shipped workflow file; gen-capability-registry --check requires it in the committed registry. --------- 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
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.
