Run all 8 cleanup skills in sequence: unused → cycles → dedupe → types → weak-types → defensive → legacy → slop. Each step verifies before the next runs; halts on first failure. Produces one consolidated report. Use when the user asks to clean up the whole codebase, run all cleanup skills, do a full code-quality pass, or sweep the repo. Example queries — "clean up the whole codebase", "run a full code-quality pass", "sweep this repo", "do all the cleanups in order".
Find and remove deprecated, legacy, and fallback code paths with zero callers. Verifies callers via repo grep + LSP before deletion. Removes unreachable fallback branches. Use when the user asks to remove deprecated code, clean up legacy paths, drop fallbacks, or simplify code branches. Example queries — "remove the deprecated API", "drop the v1 fallback", "this code is marked legacy, kill it", "simplify these branches".
Comprehensive Expo expert with access to complete official documentation covering React Native development, EAS Build, EAS Submit, EAS Update, Expo Router, Expo Modules API, configuration, deployment, and all platform features. Invoke when user mentions Expo, React Native, EAS, Expo Router, mobile app development, iOS/Android development, or cross-platform development.
Expert guidance for Plaid banking API integration including Link, Auth, Transactions, Identity, and webhook handling. Invoke when user mentions Plaid, bank connections, financial data, ACH, or banking APIs.
Token-Oriented Object Notation (TOON) format expert for 30-60% token savings on structured data. Auto-applies to arrays with 5+ items, tables, logs, API responses, database results. Supports tabular, inline, and expanded formats with comma/tab/pipe delimiters. Triggers on large JSON, data optimization, token reduction, structured data, arrays, tables, logs, metrics, TOON.
Expert on the Anthropic Claude API — Messages API, model selection (Opus/Sonnet/Haiku), prompt caching, tool use/function calling, vision, streaming, structured output, token counting, batch API, Files API, and migrating between Claude model versions. Invoke when user imports `@anthropic-ai/sdk`, asks about Claude API integration, prompt engineering, prompt caching strategy, or how to tune a Claude feature (caching, thinking, tool use, batch). Example queries — "set up prompt caching for a long system prompt", "switch this Sonnet call to Opus with the 1M context window", "stream a response with tool calling", "migrate from claude-3-5-sonnet to claude-sonnet-4-6".
