AGENTS.md Design Constraint Policy

Avoid bloated modules: Keep high-touch TUI orchestrators under 500 Lines of Code. Extract sub-logic and related tests into dedicated files.

Core Rust Implementation Mockup
// codex-rs/tui/src/bottom_pane/chat_composer.rs
pub struct ChatComposer {
    input_buffer: String,
    history: Vec<Message>,
}

impl ChatComposer {
    pub fn handle_key_event(&mut self, key: KeyEvent) {
        if let KeyCode::Char(c) = key.code {
            self.input_buffer.push(c);
        }
    }
}

Expected outcomes

  • Diagram multi-crate Rust compilation paths
  • Map seatbelt sandboxing policies and lints
