error-handling
Comprehensive error handling patterns and strategies. Use when implementing exception handling, error recovery, retry logic, circuit breakers, fallback mechanisms, or designing error hierarchies. Triggers: error, exception, try-catch, retry, fallback, circuit breaker, error propagation, error messages.
python-code-review
Reviews Python code for type safety, async patterns, error handling, and common mistakes. Use when reviewing .py files, checking type hints, async/await usage, or exception handling.
error-debugger
Analyzes errors, searches past solutions in memory, provides immediate fixes with code examples, and saves solutions for future reference. Use when user says "debug this", "fix this error", "why is this failing", or when error messages appear like TypeError, ECONNREFUSED, CORS, 404, 500, etc.
error-handling
Error handling patterns using wellcrafted trySync and tryAsync. Use when writing error handling code, using try-catch blocks, or working with Result types and graceful error recovery.
