* test(#3577): pin table-declared phase resolution across all four surfaces Failing-first regression for #3577: a GFM table phase listing (Phase header, id in the first data cell) declared real phases that roadmap.analyze, roadmap.get-phase, init.phase-op, and the milestone filter all reported as absent (phase_count: 0 / found: false). Rows pin the lookup, the scope probe, the analyzer, schema discrimination against the canonical RoadmapProgress table, fenced-example exclusion, heading+table union without double-count, decimal ids, and the 999 icebox exclusion. * fix(#3577): recognize markdown-table phase rows across the enumeration family A GFM table whose header leads with Phase and whose data rows carry the id in the first cell is a phase listing — the #2199 bullet blind spot's table sibling. collectTablePhaseRows (schema-discriminated against the canonical RoadmapProgress table via matchTableSchema, fence-aware via stripFencedCode, digit-bearing id shape, 999 icebox excluded) now feeds: the milestone filter's sole owner scanMilestonePhaseIds, window classification hasPhaseEntries, both roadmap lookup chains (getRoadmapPhaseInternal + cmdRoadmapGetPhase, as last-resort tiers after heading and bullet), and roadmap analyze's enumerator (with the same disk enrichment contract as headings and a zero-pad-tolerant duplicate guard). init.phase-op resolves through its existing getRoadmapPhaseInternal fallback. * fix(#3577): GFM table termination + icebox word boundary in the table scan Review findings: the row harvest broke only on blank lines, so prose after a table (a bare date line) could be harvested as a phase id — rows now stop at the first non-row line per GFM semantics; the 999 icebox exclusion gains the heading scan's word boundary so 9991 is kept. * fix(#3577): sanction collectTablePhaseRows in the enumeration drift scanner The scan's local 999-only exclusion mirrors its parent owner scanMilestonePhaseIds' deliberate NOT-isSentinelPhaseId choice (a leading 0 is a real decimal phase, #2554), so it cannot route through the sentinel owner — function-scoped exemption with the documented reason, same entry shape as the #3262 owner's. * chore(#3577): add changeset fragment * chore(#3577): backfill changeset pr number --------- 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.
