* fix(#621): route plan-phase post-planning-gaps through gsd_run launcher The post-planning-gaps step in gsd-core/workflows/plan-phase.md invoked gsd-tools via a hardcoded `node "$HOME/.claude/gsd-core/bin/gsd-tools.cjs"` path twice on one line — for the gap-analysis call and its nested init.plan-phase phase_req_ids query — bypassing the gsd_run launcher that every other call in the workflow uses. On non-default install/runtime layouts (relocated/global installs, non-Claude runtimes) the hardcoded path does not resolve, so the assistant reported the gap-analysis tool as "not found" and fell back to a frontmatter-only coverage check even when a working install existed. #3668 fixed this class earlier in the file but missed this block. Route both invocations through gsd_run, matching the rest of the workflow. No hardcoded $HOME gsd-tools path remains in plan-phase.md.

Update the §13e assertion to require `gsd_run gap-analysis` (still rejecting a regression to the hardcoded $HOME path), retitle it, and note the migration in the file header. The generic bare-`gsd-tools` sweeper test is unchanged — gsd_run is a resolvable launcher, not a bare gsd-tools call.

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, Gemini 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, Gemini 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, Gemini 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 your first project:
/gsd-new-project

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.
