When should I use the m06-error-handling skill?

Invoke this skill whenever you are designing error types, handling potential failures in logic, or refactoring code to improve its stability and crash-resistance.

Can this skill help with error context?

Absolutely. it emphasizes the use of .context() and mapping error types to ensure that callers have enough information to handle or log the failure effectively.

Does this skill distinguish between library and application code?

Yes, it provides specific guidance on using 'thiserror' for typed library errors and 'anyhow' for ergonomic application-level error management.

How does this help with 'unwrap' panics?

The skill provides a framework to determine if a failure is truly a bug (where panic is acceptable) or an expected outcome that should be handled with Result or Option.

API 개발

Optimizes Rust codebases by implementing robust error handling patterns and architectural decision-making frameworks.

소개

This skill provides a meta-problem-driven knowledge index that enables Claude to navigate complex Rust error handling scenarios. It helps distinguish between expected failures and bugs, guiding the implementation of Result, Option, and panic strategies. By applying this skill, developers ensure their Rust projects follow ecosystem best practices, such as utilizing thiserror for libraries and anyhow for applications, while maintaining clear error propagation and contextual debugging information.
