implement-spec

name	implement-spec
description	Implement a specification (or specific phases) for a community module package in the official-modules repo. Handles multi-phase implementation with unit tests, sandbox verification, and code-review compliance. Use when the user says "implement spec", "implement SPEC-XXX", "implement phases", "build from spec", or "code the spec". Tracks progress by updating the spec with implementation status.

Implement Spec — Community Modules

Implements a specification (or selected phases) end-to-end inside a packages/<name>/ workspace. Every community module is an external extension — use UMES extension points exclusively. NEVER modify packages/core, packages/ui, packages/shared, or any other core package.

Pre-Flight

1. Identify the spec: Locate the target spec file in .ai/specs/.
2. Check scaffold: Verify packages/<name>/ exists and has been scaffolded (package.json, build.mjs, src/modules/<moduleId>/index.ts). If not, run the scaffold-module skill first.
3. Load context: Read the spec fully. Read AGENTS.md at repo root.
4. Load code-review checklist: Read .ai/skills/implement-spec/references/code-review-compliance.md.
5. Scope phases: If the user specifies phases (e.g. "phases 1-2"), implement only those. Otherwise implement all phases sequentially.

Golden Rule

Community modules NEVER modify core. They extend it.
