- In the bottom line of the TUI, print the number of tokens to 3 sigfigs with an SI suffix, e.g. "1.23K". - Elsewhere where we print a number, I figure it's worthwhile to print the exact number, because e.g. it's a summary of your session. Here we print the numbers comma-separated.
codex-protocol
This crate defines the "types" for the protocol used by Codex CLI, which includes both "internal types" for communication between codex-core and codex-tui, as well as "external types" used with codex mcp.
This crate should have minimal dependencies.
Ideally, we should avoid "material business logic" in this crate, as we can always introduce Ext-style traits to add functionality to types in other crates.
