Fields

step: usize

Number of completed steps.

step_tool_call_count: usize

Tool calls emitted by the current step.

total_tool_call_count: usize

Total tool calls across the whole run.

total_input_tokens: usize

Cumulative input tokens across all LLM calls.

total_output_tokens: usize

Cumulative output tokens across all LLM calls.

consecutive_errors: usize

Number of consecutive rounds where all tools failed.

elapsed: Duration

Time elapsed since the loop started.

last_tool_calls: &'a [ToolCall]

Tool calls from the most recent LLM response.

last_text: &'a str

Text from the most recent LLM response.

tool_call_history: &'a VecDeque<Vec<String>>

History of tool call names per round (most recent last), for loop detection.
