Create or update test files for React components. Use when user asks to "create component tests", "test MyComponent", "generate tests for component", "update component tests", or mentions needing tests for a React component. Generates vitest test files with render, mocked sub-components, and proper test structure focusing on logic and prop validation.

Document learnings, capture repeatable workflows as skills, and prepare to compound an opence change.

Create and manage Claude Code skills following Anthropic best practices. Use when creating new skills, modifying skill-rules.json, understanding trigger patterns, working with hooks, debugging skill activation, or implementing progressive disclosure. Covers skill structure, YAML frontmatter, trigger types (keywords, intent patterns, file paths, content patterns), enforcement levels (block, suggest, warn), hook mechanisms (UserPromptSubmit, PreToolUse), session tracking, and the 500-line rule.
