Design context-sensitive help systems, tooltips, onboarding flows, and support documentation for learning platforms. Use for user assistance. Activates on "help system", "user assistance", "onboarding", or "contextual help".

Write strategic, focused tests for critical user flows and core functionality using modern testing frameworks, focusing on behavior over implementation. Use this skill when creating test files, writing unit tests, integration tests, or end-to-end tests in test directories (tests/, __tests__, spec/, *.test.js, *.spec.py). Apply this skill when testing core user workflows and business-critical features, implementing test-driven development (TDD) with red-green-refactor cycles, mocking external dependencies for isolated unit tests, using clear descriptive test names that explain expected behavior, following arrange-act-assert patterns, and ensuring tests run fast and independently. This skill prioritizes testing what matters most (primary user flows) while deferring edge cases and non-critical paths until later, emphasizes behavior testing over implementation details to reduce brittleness, and uses modern frameworks like Jest, Playwright, Cypress, pytest, RSpec, or Testing Library for reliable, maintainable test

Use when creating, designing, or building Claude Code skills. Auto-activates for "create a skill", "build a skill", "skill for X", or "make this into a skill". Provides complete 6-step creation protocol, embedded Anthropic documentation, working examples, and templates. Never need to fetch external docs again.

Comprehensive Go testing strategies including table-driven tests, testify assertions, gomock interface mocking, benchmark testing, and CI/CD integration. Use when writing test suites, setting up testing infrastructure, or ensuring code quality.

Use when writing Rails controllers, adding controller actions, or implementing state changes (close, archive, publish, assign) - enforces resource extraction instead of custom actions

Follow development best practices for project organization, version control, documentation, environment configuration, and dependency management to maintain consistency across the team. Use this skill when organizing project files and directory structures, writing or updating README files and documentation, working with git commits and branches, configuring environment variables, managing dependencies in package.json or requirements.txt, or establishing code review processes. Use this skill when working with configuration files, .env files, documentation files, or when setting up CI/CD workflows. Use this skill when implementing feature flags, maintaining changelogs, or establishing team development workflows and contribution guidelines.

Follow team development conventions for project structure, version control, and collaboration. Use this skill when organizing files and directories, writing commit messages, or setting up pull requests. When managing environment variables, dependencies, or configuration files. When establishing code review processes, testing requirements, or changelog practices. When using feature flags for incomplete features.
