Apply systematic four-phase debugging methodology (root cause investigation, pattern analysis, hypothesis testing, implementation) that ensures thorough understanding before attempting solutions, preventing random fixes and reducing debugging time from hours to minutes. Use this skill when encountering any test failures in test suites (Jest, pytest, RSpec, JUnit, Go testing), when production bugs are reported or discovered, when code produces unexpected output or behavior different from requirements, when experiencing build failures or compilation errors, when integration tests fail due to component interaction issues, when performance problems or slowdowns are detected, when encountering race conditions, timing issues, or intermittent failures, when error messages or stack traces appear in logs or console output, when refactoring causes existing tests to fail, when you've already attempted one or more fixes that didn't resolve the issue, when deployment or CI/CD pipelines fail, when you're tempted to make a

Write consistent, maintainable CSS following the project's methodology (Tailwind, BEM, utility classes, CSS modules) with design system adherence and performance optimization. Use this skill when writing or modifying styles, CSS files, utility classes, CSS-in-JS, styled components, or any styling code. Apply when working with .css, .scss, .module.css files, Tailwind utility classes, styled-components, CSS modules, design tokens (colors, spacing, typography), framework-specific styling approaches, optimizing CSS for production, implementing CSS purging or tree-shaking, or avoiding style overrides. Use for any task involving visual styling, layout styling, design system implementation, or CSS organization.

Use when creating or publishing Claude Code hooks - covers executable format, event types, JSON I/O, exit codes, security requirements, and PRPM package structure

Design and implement RESTful API endpoints following REST principles with proper HTTP methods, status codes, and resource-based URLs. Use this skill when creating or modifying API endpoints, route handlers, controllers, or API configuration files. Apply when working on REST API design, endpoint implementations, API versioning, request/response handling, HTTP method routing (GET, POST, PUT, PATCH, DELETE), query parameter filtering, API rate limiting, or any file that defines API routes such as routes.py, api.js, controllers/, endpoints/, or API documentation files.

Standards and guidelines for organizing, structuring, and maintaining documentation in the PRPM repository - ensures consistency across user docs, development docs, and internal references

Prevent common testing anti-patterns that undermine test effectiveness and code quality by ensuring tests verify real behavior rather than mock behavior, keeping production code free from test-only pollution, and enforcing thoughtful mocking strategies. Use this skill when writing or modifying any test files (.test.ts, .test.js, .spec.ts, _test.py, test_*.py, *_test.go, *_spec.rb), when adding mock objects, stubs, spies, or test doubles to test suites, when considering adding methods or properties to production classes that are only called from test code, when setting up complex test fixtures or test data, when tests are failing and you're tempted to adjust mocks to make them pass, when deciding how to isolate code under test from external dependencies, when implementing dependency injection or test seams, during code reviews when reviewing test implementation and mocking strategies, when refactoring tests that have become brittle or hard to maintain, when test setup code is becoming longer than the actual test assertions, or when choosing between integration tests with real components versus unit tests with mocks.
