Struct ToolQuota 

pub struct ToolQuota {
    pub max_calls: Option<u32>,
    pub max_duration_us: Option<u64>,
    pub max_result_bytes: Option<usize>,
}

Per-tool quota (v0.3 M3).

Limits imposed on a specific tool for the duration of a single Agent::step invocation. Counters reset at the start of each step. All fields are optional — unset means unlimited.

Example

use agnt_core::agent::ToolQuota;

let mut agent = AgentBuilder::new(backend).build()?;
agent.tool_quotas.insert(
    "shell".to_string(),
    ToolQuota {
        max_calls: Some(3),
        max_duration_us: Some(5_000_000), // 5s total shell time
        max_result_bytes: Some(16 * 1024),
    },
);

Fields

max_calls: Option<u32>

Maximum number of times this tool may be called during one step. None means unlimited.

max_duration_us: Option<u64>

Total wall-clock time across all calls to this tool during one step, in microseconds. None means unlimited.

max_result_bytes: Option<usize>

Maximum raw bytes of output per individual call. Enforced AFTER the tool runs but BEFORE envelope framing. None means use the agent-wide Agent::max_tool_result_bytes default.
