go-craft

Write, refactor, modernize, or test Go in services, CLIs, libraries, and workers. Load before editing Go, including module upgrades and concurrent code. Triggers: 'build this in Go', 'refactor this Go package', 'modernize this Go module', 'test this Go worker'. Not for runtime-only operations; use incident-investigation for incident troubleshooting. Compose with api-craft for HTTP and operator-cli for command contracts.
