Paired with Viper for config it handles the flag/env/file precedence problem most tools eventually hit. Assumption: the practitioner wants to ship binaries to end users, not just script locally.","fix":"Go's verbosity and Cobra's generator-heavy, somewhat dated API mean more boilerplate than modern alternatives; if your team isn't already in Go, the language switch is the real cost."},{"rank":2,"product":"clap","reason":"The strongest argument-parsing ergonomics in any ecosystem — derive-macro API turns a struct into a full CLI with validation, completions, and rich help; compile-time correctness plus Rust's static binaries and startup speed make it ideal for performance-sensitive tools (ripgrep, uv's ecosystem peers).
