* feat(#961): capability command mechanism — commandFamilies index + default-case dispatch (ADR-857 phase 4d-impl-1) Build the capability command mechanism per ADR-959: the `commands` declaration field on the feature role, the registry commandFamilies index, and a real dispatchCapabilityCommand consulted in runCommand's default case (replacing the dead _dispatchNonFamily shim's role). The registry DISCOVERS a standard route*Command (no rebuilt handler table). On a default-case command, dispatch enforces a bare-.cjs-basename, resolves the module under gsd-core/bin/lib/, asserts confinement, requires the resolved path, and own-property-guards the router export before calling it. A require.main===module guard makes gsd-tools.cjs importable for tests; the CLI path is unchanged. Additive: commandFamilies is empty today, so the default case is behavior- preserving for every command; the 10 dead _dispatchNonFamily sites are untouched (future migration markers). The graphify cutover is the separate next step. Closes #961 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#961): surface capability router failures structurally + enforce sync contract Review follow-up: dispatchCapabilityCommand now wraps the router invocation so an unexpected (non-ExitError) throw is converted to a structured, attributed error(msg, SDK_FAIL_FAST) — honoring --json-errors — instead of escaping as a raw stack trace; an intentional ExitError propagates unchanged. An async router (returns a thenable) is rejected loudly with a structured error (the contract is synchronous, like the 12 host routers). Not shipped as "consistent with existing behavior": the host's pre-existing version of this gap is filed as #965.

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.
