Run comprehensive code quality checks including TypeScript typecheck, ESLint linting, Prettier formatting, and Markdown validation. Auto-fixes formatting issues in agent mode or provides read-only checks for CI pipelines. Use when: (1) Before committing code changes, (2) In CI/CD pipelines for automated quality gates, (3) After making significant code changes, (4) When preparing code for review, (5) When ensuring code meets quality standards, (6) For type checking, linting, formatting, and markdown validation, (7) In pre-commit hooks, or (8) For automated quality gates before merging. Triggers: finalize, code quality, typecheck, lint, format, check code, quality check, run checks, pre-commit, before commit, CI checks, validate code.

Writing high quality Frontend React code with following best practices and conventions. Use this skill when user asks for creating new components, refactoring old components, bug fixing components.

Use before committing staged changes when you need to verify all related documentation is current - systematically checks README, CLAUDE.md, CHANGELOG, API docs, package metadata, and cross-references rather than spot-checking only obvious files

When you need check documentation about Ruby classes, modules, and methods use this skill to get full details. Avoid check source code or use `ruby -e` for documentation unless absolutely necessary.

Maps SAEF artifacts (business statement → docs) to Soracom Shortcut epics/stories, including status transitions, MCP tool usage, and GitHub linkage.

Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behavior, production pollution with test-only methods, and mocking without understanding dependencies
