startup_prompts.rs

1//! The flags that take each harness past its routine startup prompts, in one table
2//! (`startup_prompts.json`, which the TypeScript SDK reads as its own copy) for every launch path:
3//! `supercode open --new`, a resume, a native start. `startup` pairs answer the prompts every launch
4//! meets (Codex's new-version check, its trust-this-folder question); `unattended` flags answer the
5//! approval prompts of a launch nobody watches, unless the caller chose its own
6//! (`unattended_chosen_by`). `{cwd}` in a flag is the launch's directory as a JSON string, the form a
7//! Codex `-c projects={…}` table takes it in; a pair that needs it is left out without one.
