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 > **Layer 1: Language Mechanics** ## Core Question **Is this failure expected or a bug?** Before choosing error handling strategy: - Can this fail in normal operation? - Who should handle this failure? - What context does the caller need? --- ## Error → Design Question | Pattern | Don't Just Say | Ask Instead | |---------|----------------|-------------| | unwrap panics | "Use ?" | Is None/Err actually possible here? | | Type mismatch on ? | "Use anyhow" | Are error types designed correctly? | | Lost error context | "Add .context()" | What does the caller need to know? | | Too many error variants | "Use Box<dyn Error>" | Is error granularity right? | --- ## Thinking Prompt Before handling an error: 1. **What kind of failure is this?** - Expected → Result<T, E> - Absence normal → Option<T> - Bug/invariant → panic! - Unrecoverable → panic! 2. **Who handles this?** - Caller → propagate with ? - Current function → match/if-let - User → friendly error message - Programmer → panic with message 3. **What context is needed?** - Type of error → thiserror variants - Call chain → anyhow::Context - Debug info → anyhow or tracing …

How to install
mdr add moeru-ai/auv/m06-error-handling@sha256:9760e9433bfaacdeThe line at the top of this page pins the label git:20260725.8a8e541, 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.
