Idiomatic Golang error handling

golang-error-handling is an agent skill from the samber cc-skills-golang collection that guides a coding agent to write idiomatic, debuggable error handling in Go. It covers creating errors, wrapping them with %w to keep context, checking them with errors.Is and errors.As, combining them with errors.Join, defining custom error types and sentinel errors, and using panic and recover only where they belong. It also sets out a single-handling rule, so an error is either handled or returned with context, never both logged and returned, and it asks for structured logging. The skill works in three modes. Coding mode applies the practices while new code is written. Review mode checks a pull request's error changes for swallowed errors, missing wrapping context, log-and-return pairs and panic misuse. Audit mode runs up to five parallel sub-agents across an existing codebase, each covering one category: creation, wrapping, the single-handling rule, panic and recover, and structured logging. The skill is listed on skills.sh, where the page shows install counts, GitHub stars and security audit results. Install it with npx skills add https://github.com/samber/cc-skills-golang --skill golang-error-handling.
