go vet [-n] [-x] [-json] [-vettool prog] [packages]

go vet examines Go source code and reports suspicious constructs that the compiler does not catch, using heuristics that do not guarantee all reports are genuine problems. It checks for issues such as incorrect printf format strings, unreachable code, suspicious function calls, misuse of sync primitives, and incorrect struct tags.The tool is part of the standard Go toolchain and runs without executing the code. It is typically used alongside tests and linters as part of a continuous integration workflow. Individual analyzers can be enabled or disabled (e.g., `-printf=false`). Run `go tool vet help` to see available analyzers and their flags.
