Skills (5)

• builder-factory

  Use this skill to create typed test data builders with mimicry-js and Faker for any TypeScript interface or type. Invoke whenever the user asks to generate mock data, create test fixtures, build factory functions, produce seed data, or construct fake objects for unit tests, Storybook stories, or E2E

• builder-rules-ts

  Rules for building test data in TypeScript with mimicry-js builders: explicit values for everything a test asserts on, .one() and .many() with overrides and traits, generator placement, fixed() for functions, resetting state. Use when creating or using a builder in a test or story. Background knowle

• coverage-gaps

  Find and rank the test-coverage gaps that actually matter — untested auth, payment, server actions, validation, and error paths — weighting uncovered branches and recent churn over raw line percentages. Use this skill whenever the user asks what's untested, where coverage is weak, what tests are mis

• dead-code

  Find dead code — unused files, exports, types, and dependencies — and propose safe removal refactors. Uses Knip's dependency-graph reachability analysis as the deterministic engine so the expensive part (walking a large source tree) never happens token-by-token, then ranks and reads only the candida

• unit-testing

  Write unit tests with Vitest for TypeScript logic — `vi.mock` / `vi.fn` / `vi.spyOn`, `test.each` parameterized cases, async error assertions, Server Actions with mocked dependencies, and `vitest.config.ts` coverage setup. Trigger when the user says "unit test", "test this function", "test the serve

• library-updater

  Update npm packages, investigate breaking changes, execute migrations, and verify code quality after dependency updates. Use when updating libraries or fixing post-update issues.

• unit-tester

  Use when: writing Vitest unit tests for TypeScript logic — utilities, pure functions, Zod schemas, custom hooks, and Server Actions with mocked dependencies; adding test coverage for a module; or when the user says "unit test", "test this function", "test the server action", "test my schema/hook" fo
