How does this improve user experience?

By distinguishing between user-facing errors (actionable) and internal errors (generic), users get clearer guidance while sensitive system details remain hidden.

What is the m13-domain-error skill?

It is a specialized Claude Code skill designed to help Rust developers architect sophisticated error handling strategies, focusing on categorization and recovery.

Does this skill help with specific Rust crates?

Yes, it provides implementation patterns using popular crates such as thiserror, anyhow, tokio-retry, and failsafe-rs.

When should I use a circuit breaker instead of a retry?

Use retries for transient, isolated failures; use circuit breakers to prevent cascading failures when a downstream service is consistently failing.

API Development

Architects resilient Rust applications by designing structured domain error hierarchies and recovery strategies.

About

The m13-domain-error skill provides a comprehensive framework for managing errors within the Rust ecosystem, focusing on the critical distinction between user-facing actions and internal system failures. It guides developers through the implementation of advanced resilience patterns—such as exponential backoff retries, circuit breakers, and graceful degradation—while providing best practices for using industry-standard crates like thiserror and anyhow to maintain high-quality, debuggable code.

Key Features

Resilience strategies including circuit breakers and fallbacks
Implementation patterns for retries with exponential backoff
Categorized error hierarchies for users, developers, and ops
Best practices for context-rich logging and structured errors
Anti-pattern identification for cleaner Rust application design
596 GitHub stars

Use Cases

Architecting robust error response systems for public APIs
Implementing automated retry logic for unreliable external services
Designing domain-specific failure recovery in fintech or high-availability systems
