* fix(#2440): per-counter progress ratchet — total_plans always takes derived value Two sites fixed (targeted — existing body-only write tests preserved): Site A — read path: shouldPreserveExistingProgress (state-document.cts:167) removed total_plans from the all-or-nothing ratchet check. It now joins total_phases as an always-derived counter. Only completed_phases and completed_plans keep ratchet behaviour (they are monotonic). This fixes gsd-tools query state.json reporting stale total_plans when a curated completed_plans triggers the ratchet. Site B — write path: applyStatePreservation (state-transition.cts:162) gained a deriveProgressKeys opt-in flag. When true (passed by cmdStatePlannedPhase only), total_plans and total_phases take the derived (post-sync) value instead of the wholesale curated restore. When false (the default — state.update, state.patch), the existing #3242 wholesale protection stays fully in force. This fixes the state planned-phase verb writing a stale total_plans. The opt-in approach preserves all 8 existing #3242/#1264/#500 body-only write tests that assert wholesale progress preservation during non- progress updates. Tests: - tests/state.test.cjs: 4 unit tests for shouldPreserveExistingProgress (total_plans upward/downward/equality + completed_plans ratchet active). - tests/state-transition.test.cjs: 2 #2440 regression tests for deriveProgressKeys=true (total_plans takes derived; boundary at equality). The existing !resync wholesale-restore test stays unchanged (default behavior preserved). References: #2440; #1446 (total_phases read-path fix — same principle); #3242 Bug A (body-only preservation — protection preserved via the opt-in gate); ADR-1769 (applyStatePreservation table-driven preservation). * chore(#2440): backfill pr:2468 in .changeset/mellow-eagles-chatter.md
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.
