A skills-only role:feature third-party capability installed 'active' but its skills never reached the runtime surface, capability enable/set rejected it as 'unknown capability', and capability list disagreed with capability state. Three defects, fix shape 1b (teach resolveSurface, no on-disk linking):
D1 (materialization): resolveSurface built the surfaced skills Set only from the on-disk manifest; third-party cap skills live at ~/.gsd/capabilities/<id>/skills/ and never entered the Set -> surfaced:false. Fix: union registry.capabilityClusters values into the Set in the full-profile branch (idempotent for first-party, additive for third-party; prototype-pollution guarded).
D2 (enable/set unknown): setCapabilityState validated the capId against the static first-party registry instead of the composed overlay-aware registry. Fix: validate against loadRegistry({includeInstalled}) like capability-state.cts does.
D3 (list vs state): capability list derived status purely from ledger existence, never surface composition. Fix: add a 'surfaced' field to list rows sourced from the same resolver capability state uses, so list and state agree.
Regression coverage: tests/issue-2045-third-party-skills-surface.test.cjs asserts all five acceptance criteria (resolveSurface union, state surfaced:true, enable/set not-unknown, list/state agreement, first-party + unknown-id regression). gsd-test: 23916/23916 green (linux-node22 + linux-node24).
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.
