Use when the user mentions "firstrun", "first run", "setup", "setup library", "configure templates", or "link templates".

Update Java test classes and methods to work with new code versions after refactoring or modifications. Use when code changes break existing tests due to signature changes, refactoring, or behavior modifications. Takes old and new code versions plus old tests as input, and outputs updated tests that compile and pass against the new code. Handles method signature changes, class refactoring, assertion updates, and mock modifications.

Apply direct, functional TypeScript and JavaScript coding style preferences. Use when writing, editing, reviewing, or refactoring TS/JS code; deciding whether to introduce classes, factories, helpers, wrappers, utilities, shared modules, types vs interfaces, validation boundaries, or recoverable error handling; or when the user asks for code that matches these personal style preferences.

Explains test failures and provides actionable debugging guidance. Use when tests fail (unit, integration, E2E), builds fail, or code throws errors. Analyzes error messages, stack traces, and test output to identify root causes and suggest concrete fixes. Handles pytest, jest, junit, mocha, vitest, selenium, cypress, playwright, and other testing frameworks across Python, JavaScript/TypeScript, Java, Go, and other languages.

Generate secure Cloudflare Worker code in TypeScript that avoids all weaknesses covered by OWASP Top 10 (2025) and CWE Top 25 (2025). Use this skill whenever the user asks to create, write, scaffold, or generate a Cloudflare Worker, CF Worker, edge function, or serverless function on Cloudflare. Also trigger when the user asks to build a secure API, secure endpoint, secure webhook handler, or any TypeScript code targeting the Workers runtime. Always use this skill over generic code generation when the target is Cloudflare Workers.
