SKILL.md

This skill provides guidelines for implementing robust error handling in Go applications. Apply these practices when writing, reviewing, or refactoring Go code that involves error creation, propagation, or handling.

| error-wrapping.md | How to wrap errors with %w for chain inspection | Use when returning errors from functions to preserve the error chain. Essential if callers need to use errors.Is() or errors.As(). |

| error-types.md | When to use sentinel vs typed errors | Use when deciding between var ErrXxx = errors.New() and custom error structs. Prefer typed errors when you need to attach metadata like resource IDs or permissions. |
