# tool-loop-break

[![crates.io](https://img.shields.io/crates/v/tool-loop-break.svg)](https://crates.io/crates/tool-loop-break)

Sliding-window detector for runaway agent tool loops. Trips when the
same `(tool, args_fingerprint)` appears `>= threshold` times inside
the recent `window`.

```rust
use tool_loop_break::LoopDetector;
let mut d = LoopDetector::new(10, 3);
if d.record("read_file", "abc") {
    // loop! break out of the agent run
}
```
