Go Development and Debugging
What it does
Writes, debugs, and reviews Go: goroutine leaks, data races, nil interfaces, slices and maps, go.mod, and net/http. Use when Go panics or misbehaves — "all goroutines are asleep - deadlock!", "concurrent map writes", "send on closed channel", "assignment to entry in nil map", or a WARNING: DATA RACE from `go test -race`; when a goroutine, timer, or connection leaks and memory climbs; when a service hangs for want of a timeout; when errors.Is or errors.As stops matching after a %v wrap; when a slice mutates its parent, a map iterates in a new order, or a typed nil returned as error compares non-nil; when go.mod, go.sum, workspaces, replace, or a /v2 path fight over dependencies; when cross-compiling, cgo, build tags, go:embed, or a static container binary fail; when tests are flaky under -race or -parallel or benchmarks lie; when GOGC, GOMEMLIMIT, GOMAXPROCS, or escape analysis need tuning; or when writing handlers, CLIs, database access, or generics. Not for Kubernetes operators or framework internals.
