* fix(#1140): implement state add-roadmap-evolution CJS handler `query state.add-roadmap-evolution` was unreachable: the CJS state router listed it in the `unsupported` map with a circular message ("...is SDK-only. Use: gsd-tools query state.add-roadmap-evolution ...") and no CJS handler existed after the SDK retirement (ADR-0174). Every `/gsd:phase insert` and `/gsd:phase --edit` run hit a dead end recording Roadmap Evolution. Re-implement `cmdStateAddRoadmapEvolution` in CJS (src/state.cts) and wire it into the state router; remove the now-stale `unsupported` entry. The handler appends a single-line bullet under `## Accumulated Context` → `### Roadmap Evolution` (creating the subsection/section if missing, deduping identical entries), scoping every lookup to the Accumulated Context body so a decoy heading in an unrelated section is never targeted, and flattening multiline notes to a single bullet. Section-boundary regexes mirror the sibling add-decision/add-blocker handlers and preserve following sections on CRLF input. Regression cases live in tests/state.test.cjs (per the no-new-bug-NNNN-files policy) and cover the literal issue repro plus the CLI/parser QA matrix (missing/empty/whitespace note, flag-shaped value, duplicate flags, hostile shell metacharacters, Unicode, decoy section, CRLF, missing STATE.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, Gemini 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, Gemini 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, Gemini 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 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.
