Struct DoomLoopDetector 

pub struct DoomLoopDetector { /* private fields */ }

Detects doom loops in agent tool call sequences.

Implementations

impl DoomLoopDetector

pub fn new(config: DoomLoopConfig) -> Self

Creates a new detector with the given configuration.

pub fn record_and_check( &mut self, name: &str, arguments: &Value, ) -> Option<DoomLoopType>

Records a tool call into the detection history and checks for doom loops against the current and past tool calls.

Two detection strategies are applied in order:

1. Consecutive duplicates — the same tool with the same canonical arguments called N times in a row (configured by DoomLoopConfig::consecutive_threshold).
2. Cyclic patterns — a repeating sequence of tool calls of length between min_cycle_length and max_cycle_length that repeats at least cycle_repetitions times.

Returns Some(DoomLoopType) if a doom loop is detected, None otherwise.

pub fn clear(&mut self)

Clears the detection history.

pub fn history_len(&self) -> usize

Returns the current history length.
