Use when writing, reviewing, or refactoring vitest tests. Load when you see *.test.ts or *.spec.ts files, nested describe blocks, loose assertions (toBeTruthy), over-mocking, slow tests, or async testing needs. Covers AAA pattern, parameterized tests, test doubles hierarchy, mock cleanup, test isolation, and performance optimization. Keywords include vitest, testing, TDD, assertions, mocks, stubs, fakes, spies, beforeEach, describe, it, expect, vi.mock, it.each.
Diagnose ClickHouse disk usage, compression efficiency, part sizes, and storage bottlenecks. Use for disk space issues and slow IO.
Optimize your SaaS app across four dimensions - Speed (page load, API response), Code (unused files, dead code), Database (orphaned data, schema hygiene), and Dependencies (package bloat, bundle size). Use when app feels slow, codebase feels bloated, or after significant development work accumulates. Each path follows AUDIT → CLEAN → PREVENT workflow.
Generate web assets including favicons, app icons (PWA), and social media meta images (Open Graph) for Facebook, Twitter, WhatsApp, and LinkedIn.
