go vet examines Go source code and reports suspicious constructs that the compiler does not catch. It finds bugs like incorrect printf format strings, unreachable code, and misuse of sync primitives.The tool runs multiple analyzers that check for common mistakes. It is part of the standard quality assurance workflow alongside testing and formatting.
