Next.js performance optimization and best practices. Use when writing Next.js code (App Router or Pages Router); implementing Server Components, Server Actions, or API routes; optimizing RSC serialization, data fetching, or server-side rendering; reviewing Next.js code for performance issues; fixing authentication in Server Actions; or implementing Suspense boundaries, parallel data fetching, or request deduplication.
accelint-ts-testing
by gohypergiant
Comprehensive vitest testing guidance for TypeScript projects. Use when (1) Writing new tests with AAA pattern, parameterized tests, or async/await, (2) Reviewing test code for anti-patterns like loose assertions (toBeTruthy), over-mocking, or nested describe blocks, (3) Optimizing slow test suites, (4) Implementing property-based testing with fast-check - especially for encode/decode pairs, roundtrip properties, validators, normalizers, and idempotence checks. Covers test organization, assertions, test doubles hierarchy (fakes/stubs/mocks), async testing, performance patterns, and property-based testing patterns. Trigger keywords on vitest, *.test.ts, describe, it, expect, vi.mock, fast-check, fc.property, roundtrip, idempotence.
accelint-ts-best-practices
by gohypergiant
Comprehensive TypeScript/JavaScript coding standards focusing on type safety, defensive programming, and code correctness. Use when (1) Writing or reviewing TS/JS code, (2) Fixing type errors or avoiding any/enum/null, (3) Implementing control flow, state management, or error handling, (4) Applying zero-value pattern or immutability, (5) Code review for TypeScript anti-patterns. Covers naming conventions, function design, return values, bounded iteration, input validation. For performance optimization, use accelint-ts-performance skill. For documentation, use accelint-ts-documentation skill.

personal-assistant
by auldsyababua
This skill should be used whenever users request personal assistance tasks such as schedule management, task tracking, reminder setting, habit monitoring, productivity advice, time management, or any query requiring personalized responses based on user preferences and context. On first use, collects comprehensive user information including schedule, working habits, preferences, goals, and routines. Maintains an intelligent database that automatically organizes and prioritizes information, keeping relevant data and discarding outdated context.
