aico-frontend-implement
Execute frontend task implementation with TDD. Read task file, execute implementation steps, verify each step, update status.
Use this skill when:
- User asks to "implement this task", "implement the plan", "start implementation", "execute plan"
- Have a task file (story- or standalone- prefix) ready to execute
- User says "start coding", "write the code", "begin implementation"
- User asks to "use TDD", "write test first", "test-driven" for frontend code
- User asks to "write tests", "add tests", "create tests"
- Fixing UI bugs (write failing test that reproduces bug first)
TDD Iron Law: NO PRODUCTION CODE WITHOUT A FAILING TEST FIRST
TDD Cycle: RED (write failing test) → Verify fails → GREEN (minimal code) → Verify passes → REFACTOR
Prerequisites:
- MUST have task file in docs/reference/frontend/tasks/ (story- or standalone- prefix)
- MUST read design-system.md, constraints.md, and design spec before writing any code
Flow: Read Task File → Read Constraints → Execute Steps → Verify Each → Test → Update Task Status

cc-debugging
Guide systematic debugging using scientific method: STABILIZE -> HYPOTHESIZE -> EXPERIMENT -> FIX -> TEST -> SEARCH. Two modes: CHECKER audits debugging approach (outputs status table with violations/warnings), APPLIER guides when stuck (outputs stabilization strategy, hypothesis formation, fix verification). Use when encountering ANY bug, error, test failure, crash, wrong output, flaky behavior, race condition, regression, timeout, hang, or code behavior differing from intent. Triggers on: debug, fix, broken, failing, investigate, figure out why, not working, it doesn't work, something's wrong.
