error-handling
by 101mare
Patterns for exception handling across application layers: mapping, retry, severity, logging. Does NOT handle: exception hierarchies (use exception-builder), circuit breakers (use resilience-patterns), API errors (use api-design), logging config (use logging-builder). Use when designing error strategies, implementing retry logic, or mapping exceptions between layers. Recognizes: "error-handling", "exception handling", "retry pattern", "error strategy", "exception mapping", "error boundaries", "backoff pattern", "error propagation"
shortening-feedback-loops
by Coowoolf
Use when decisions seem to require years to evaluate, when hiding behind long-term vision to avoid accountability, or when struggling to learn from venture/product bets in real-time
backend
by mrsknetwork
Implements server-side application logic, data access layers, and background services using Python 3.12 and FastAPI. Use for building service classes, repositories, background tasks, middleware, or any Python code that runs on the server. Always ask about the existing stack before applying defaults.
