Go Context Best Practices
Implements idiomatic Go context patterns for handling timeouts, cancellations, and request-scoped data.
This skill equips Claude with specialized knowledge for managing Go's context.Context according to production standards from Google, Uber, and the wider Go community. It ensures contexts are passed correctly as the first parameter, prevents common anti-patterns like storing contexts in structs, and provides guidance on propagating deadlines and cancellation signals. It is an essential tool for developers building resilient Go services that need to handle long-running operations and complex request lifecycles efficiently.
