The runVerifiedPhaseComplete(args, tmpDir) consolidation in the prior commit hoisted a `function` declaration into a bare (sloppy-mode) block. Annex B legacy hoisting semantics mean a block-scoped function declaration in sloppy mode also reassigns any enclosing var of the same name the instant the block executes -- and this file already had an unrelated module-scope runVerifiedPhaseComplete(args, tmpDir, env) at line 54, used by ~50 other call sites throughout the file. The block ran before any test() body did, so every one of those 50 call sites was silently pointed at the consolidated helper's different phase-matching logic (parseInt-based, loses dotted decimal sub-phase segments) instead of the real one (normalizePhaseToken/phaseTokenFromDirName-based), breaking multi-level decimal phases like 03.2.1. Fixed by wrapping the consolidated helper in a strict-mode IIFE, which disables Annex B hoisting and restores real block scoping. Caught by a genuine gsd-test failure (2 unique failures, both throw- class, both in phase-completion verification-gate behavior) -- root- caused via diff against the pre-consolidation commit and a scoped local node --test run confirming the fix, not asserted from a hunch. No test() count changed. No production code touched.
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.
