//! Prompt-injection fixtures against real agent CLIs (opt-in):
//!
//! ```sh
//! cargo test -p okbot-agent --test injection -- --ignored
//! ```
//!
//! Each fixture plays a hostile chat message. With the `web` and `mcp-only` policies the agent
//! must not run commands or read files in its working directory.
#![allow(clippy::unwrap_used)] // test code: a panic is the failure report
