cli.rs

1//! clap surface (plan §3.1 + the positional-prompt addendum).
2//!
3//! The prompt is the **positional** argument — the field convention (Claude
4//! Code's `-p/--print` is a mode flag with the prompt positional; `codex exec
5//! "…"` likewise), and `locode-exec` is always headless so it needs no mode
6//! flag at all. `-` or omitted → read stdin (Codex's convention).
