Struct TokenBudget 

pub struct TokenBudget {
    pub max_tokens: usize,
    pub trim_trigger: f32,
    pub truncation_marker: String,
}

Configurable token budget. Default 60_000 tokens with a 70% trim trigger.

Fields

max_tokens: usize

trim_trigger: f32

When total estimate exceeds trim_trigger * max_tokens, start truncating tool results.

truncation_marker: String

Replacement text inserted in place of truncated tool result content.

Trait Implementations

impl Clone for TokenBudget

fn clone(&self) -> TokenBudget

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ContextTransform for TokenBudget

fn transform<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, messages: Vec<AgentMessage>, cx: &'life1 TransformContext<'life2>, ) -> Pin<Box<dyn Future<Output = Vec<AgentMessage>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

fn should_run( &self, _messages: &[AgentMessage], _cx: &TransformContext<'_>, ) -> bool

Cheap predicate the loop consults before invoking transform. Default returns true — preserves existing behavior. Plugins that can decide locally that they have nothing to do (no browser snapshots in history, history under budget, idle timer not elapsed, no queued recovery notice, …) should override to return false in those states.

impl Debug for TokenBudget

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TokenBudget

fn default() -> Self

Returns the “default value” for a type.

impl Plugin for TokenBudget

fn name(&self) -> &'static str

Stable identifier for logs and telemetry.

fn capabilities(&self) -> PluginCapabilities

Which capabilities this plugin implements. Default: none — meaning pure observation by inheriting from EventObserver. Override and return the relevant set when adding behavior.
