Struct ToolAnnotations 

pub struct ToolAnnotations {
    pub read_only: bool,
    pub destructive: bool,
    pub idempotent: bool,
    pub requires_approval: bool,
    pub estimated_duration_ms: Option<u64>,
}

Behavioral annotations that help the Kernel make policy and scheduling decisions without inspecting the tool implementation.

Fields

read_only: bool

Whether the tool only reads data (no side effects).

destructive: bool

Whether the tool may cause irreversible changes.

idempotent: bool

Whether invoking the tool twice with the same input yields the same result.

requires_approval: bool

Whether a human must approve each invocation.

estimated_duration_ms: Option<u64>

Expected execution time in milliseconds (for timeout planning).
