accelint-command-creator
Guide for creating Claude Code commands with skill integration. Use when users want to create a new Claude Code command specification, whether skill-based or standalone. Assists with command definition, skill discovery, argument specification, and command generation.
accelint-nextjs-best-practices
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-react-best-practices
React performance optimization and best practices. Use when writing React components, hooks, or JSX; refactoring React code; optimizing re-renders, memoization, or state management; reviewing React code for performance issues; fixing hydration mismatches; or implementing transitions, lazy initialization, or effect dependencies. Covers React 19+ features including useEffectEvent, Activity component, and ref props.
accelint-readme-writer
Use when creating or editing a README.md file in any project or package. Recursively parses codebase from README location, suggests changes based on missing or changed functionality, and generates thorough, human-sounding documentation with copy-pasteable code blocks and practical examples.
accelint-skill-manager
Use when users say "create a skill", "make a new skill", "build a skill", "skill for X", "package this as a skill", or when refactoring/updating/auditing existing skills that extend agent capabilities with specialized knowledge, workflows, or tool integrations.
accelint-ts-best-practices
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.
accelint-ts-documentation
Audit and improve JavaScript/TypeScript documentation including JSDoc comments (@param, @returns, @template, @example), comment markers (TODO, FIXME, HACK), and code comment quality. Use when asked to 'add JSDoc', 'document this function', 'audit documentation', 'fix comments', 'add TODO/FIXME markers', or 'improve code documentation'.
accelint-ts-performance
Systematic JavaScript/TypeScript performance audit and optimization using V8 profiling and runtime patterns. Use when: (1) Users say 'optimize performance', 'audit performance', 'this is slow', 'reduce allocations', 'improve speed', 'check performance', (2) Analyzing code for performance anti-patterns (O(n²) complexity, excessive allocations, I/O blocking, template literal waste), (3) Optimizing functions regardless of current usage context - utilities, formatters, parsers are often called in hot paths even when they appear simple, (4) Fixing V8 deoptimization (monomorphic/polymorphic issues, inline caching). Audits ALL code for anti-patterns and reports findings with expected gains. Covers loops, caching, batching, memory locality, algorithmic complexity fixes with ❌/✅ patterns.
accelint-ts-testing
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.
