Curated library of 16 public Ruby AI agent skills: 10 atomic skills (YARD docs, service objects, calculator pattern, API clients, DDD, bug triage, code review, skill routing), 5 process-discipline skills (TDD, refactoring, review, security, test planning), and 1 planning skill (TDD task generation). Zero agents — this is a foundational library consumed by framework-specific tiles like rails-agent-skills and hanakai-yaku.

Example: Reproduce order creation out-of-stock failure
User task: "Creating an order for an out-of-stock product should return a 422 with 'Out of stock', but it currently succeeds or crashes. Create a failing test that reproduces the bug and produce a minimal fix plan."
Expected triage output (JSON):
{ "title": "Order creation ignores out-of-stock guard", "reproduction_steps": [ "Create product with stock: 0", "POST /orders with quantity: 1", "Observe response status/body and whether an order row was created" ], "failing_command": "bundle exec rspec spec/requests/orders_spec.rb", "failing_tests": ["POST /orders when product is out of stock returns 422 with Out of stock"], "minimal_fix_plan": [ "Add the failing request test before touching implementation", "Update Orders::CreateOrder to guard stock before creating the order", "Return { success: false, error: 'Out of stock' } and no persisted order", "Run the focused request test, related order tests, and the full suite" ] }
Use the inline request test skeleton in SKILL.md for the failing test when the bug is visible through POST /orders. Use assets/spec-skeletons/reproduction_spec.rb only for generic service-boundary bugs.
