Master error handling patterns across languages including exceptions, Result types, error propagation, and graceful degradation to build resilient applications. Use when implementing error handling, designing APIs, or improving application reliability.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Error Handling Patterns Build resilient applications with robust error handling strategies that gracefully handle failures and provide excellent debugging experiences. ## When to Use This Skill - Implementing error handling in new features - Designing error-resilient APIs - Debugging production issues - Improving application reliability - Creating better error messages for users and developers - Implementing retry and circuit breaker patterns - Handling async/concurrent errors - Building fault-tolerant distributed systems ## Core Concepts ### 1. Error Handling Philosophies **Exceptions vs Result Types:** - **Exceptions**: Traditional try-catch, disrupts control flow - **Result Types**: Explicit success/failure, functional approach - **Error Codes**: C-style, requires discipline - **Option/Maybe Types**: For nullable values **When to Use Each:** - Exceptions: Unexpected errors, exceptional conditions - Result Types: Expected errors, validation failures - Panics/Crashes: Unrecoverable errors, programming bugs ### 2. Error Categories **Recoverable Errors:** - Network timeouts - Missing files - Invalid user input - API rate limits **Unrecoverable Errors:** …

How to install
mdr add dicklesworthstone/pi_agent_rust/error-handling-patterns@sha256:e3994dd57742ff26The line at the top of this page pins the label git:20260205.788be98, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
