Adds custom `/prompts` to `~/.codex/prompts/<command>.md`. <img width="239" height="107" alt="Screenshot 2025-08-25 at 6 22 42 PM" src="https://github.com/user-attachments/assets/fe6ebbaa-1bf6-49d3-95f9-fdc53b752679" /> --- Details: 1. Adds `Op::ListCustomPrompts` to core. 2. Returns `ListCustomPromptsResponse` with list of `CustomPrompt` (name, content). 3. TUI calls the operation on load, and populates the custom prompts (excluding prompts that collide with builtins). 4. Selecting the custom prompt automatically sends the prompt to the agent.
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.
