2 things to look at
- no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
- 2 stars2 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

Goal: failures that are visible, contextual, and handled deliberately.
Use for:
- deciding how functions signal and propagate failure
- reviewing try/catch, error types, and recovery
- fixing swallowed errors and vague messages
Workflow:
- Distinguish expected failures from programmer bugs.
- Model expected errors explicitly (results or typed exceptions).
- Handle errors where you can act; otherwise propagate with context.
- Add context as errors cross boundaries, without losing the cause.
- Fail fast on invariant violations; do not limp on.
- Surface actionable messages; log details once, near the source.
Patterns:
- typed errors or result types over generic throws
- wrap-and-rethrow to add context, preserving the cause
- retry with backoff for transient failures only
- a single place that maps errors to user-facing responses
Rules:
- never swallow an error silently
- do not catch broadly just to continue; handle or rethrow
- include context, never the bare message
- distinguish retryable failures from permanent ones
