Engine tests pass standalone\n2. Namespace properly isolated\n3. Migrations won't conflict\n4. Dependencies clearly declared\n\n---\n\n## Phase 3: Implementation & Review\n\n1. **Implement features** using:\n   - tdd agent for complex features\n   - Individual skills for simple additions\n\n2. **skills/review-engine** *(sub-skill — invoke separately)*\n\n3. **skills/upgrade-engine** *(sub-skill — invoke separately)*\n\n**Check gem dependencies:**\n```bash\nbundle exec rake dependencies\nbundle exec bundler-audit check --update\n```\n\n---\n\n## Phase 4: Documentation & Release\n\n1. **skills/document-engine** *(sub-skill — invoke separately)* — Installation, configuration, usage examples, changelog\n\n2. **skills/release-engine** *(sub-skill — invoke separately)* — Version bump (SemVer), changelog, upgrade notes, git tag\n\n**Release commands:**\n```bash\ngem build my_engine.gemspec\ngem push my_engine-1.0.0.gem\ngit tag v1.0.0 && git push origin v1.0.0\n```\n\n**Optional:**\n3. **skills/create-engine-installer** — Idempotent `rails g my_engine:install` generator for host app configuration\n\n**Output:** Published gem or releasable GitHub repository.\n\n---\n\n## Quick Reference\n\n```\nNew engine?        → create-engine → test-engine\nExtract from app?  → extract-engine → create-engine\nRelease engine?    → review-engine → release-engine\nNot sure?          → skill-router\n```\n\n---\n\n## Common Anti-Patterns\n\n| Anti-Pattern | Fix |\n|---|---|\n| **Namespace leakage** — `::MyEngine` instead of `MyEngine::` | Verify `isolate_namespace MyEngine` in `engine.rb` |\n| **Migration conflicts** — Migrations outside engine dir or missing path config | Run engine migrations in isolation via dummy app |\n| **Missing gemspec dependencies** — Runtime gems in Gemfile but not in `.gemspec` | Run `bundle exec rake dependencies` and `bundler-audit check` at Phase 3 end |\n| **Dummy app load errors** — Missing `require` or incorrect `spec_helper` | Use test-engine sub-skill diagnostic steps |\n","tagline":"Use when running the full engine loop: author, test, review, release.
