Automatic code quality and best practices analysis. Use proactively when files are modified, saved, or committed. Analyzes code style, patterns, potential bugs, and security basics. Triggers on file changes, git diff, code edits, quality mentions.
Use when creating/writing/building OpenRewrite recipes, working with .java recipe files, RewriteTest files, recipe YAML files, LST visitors, JavaTemplate, visitor patterns, or when discussing recipe types (declarative YAML, Refaster templates, imperative Java recipes) - guides creation of OpenRewrite recipes for automated code transformations, AST manipulation, custom refactoring rules, and code migration.
Automatically suggest tests for new functions and components. Use when new code is written, functions added, or user mentions testing. Creates test scaffolding with Jest, Vitest, Pytest patterns. Triggers on new functions, components, test requests, testing mentions.
Analyze TypeScript code structure using ts-morph. Use for summarizing class/interface APIs, listing exports, showing inheritance hierarchies, or extracting interfaces from classes. Outputs signatures without implementation details.
Architecture audit worker (L3). Checks DRY (7 types), KISS/YAGNI, layer breaks, error handling, DI patterns. Returns findings with severity, location, effort, recommendations.
Coordinates linters, pre-commit hooks, and test infrastructure setup
AST-based structural code search, security scanning, and refactoring using ast-grep (sg CLI). Supports 40+ languages with pattern matching and code transformation.
Create unique, visually appealing frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.
How to work with Python (`uv` instead of `python`, modern type syntax, linting, formatting, etc.)
Apply language-specific style guide rules to your code. Use when writing or reviewing code to ensure consistency with best practices.
Deep architectural analysis using Gemini's codebase_investigator tool. Trigger when user needs architecture overview ("analyze this codebase", "map dependencies"), onboarding to unfamiliar code, understanding legacy systems, or identifying technical debt.
Codebase analysis using Codex CLI with read-only sandbox. Trigger when user needs architecture overview ("analyze this codebase with Codex", "have Codex map dependencies"), onboarding to unfamiliar code, understanding legacy systems, or identifying technical debt.
Get Gemini's code review of git changes after Claude makes edits. Trigger when user wants a second opinion on code changes ("have Gemini review my changes", "get code review from Gemini", "review this diff"), or as a final check before committing.
Get Codex's code review of git changes after Claude makes edits. Trigger when user wants a second opinion on code changes ("have Codex review my changes", "get code review from Codex", "review this diff with Codex"), or as a final check before committing.
