Struct PlannerConfig 

Source 
pub struct PlannerConfig {
    pub cost_weight: f64,
    pub action_budget: usize,
    pub tool_call_budget: usize,

}
Expand description

Configuration for proposal scoring.

Fields§

§cost_weight: f64

Weight for cost efficiency in the score (0.0–1.0). Higher = prefer cheaper proposals. Lower = prefer correctness.

§action_budget: usize

Maximum actions before a proposal is penalized.

§tool_call_budget: usize

Maximum tool calls before a proposal is penalized.

§conflict_penalty: f64

Validity penalty per write conflict detected in simulated state.

§feedback_weight: f64

How much historical tool feedback influences the final score (0.0–1.0). Score = base * (1.0 - feedback_weight + feedback_weight * confidence). At 0.0 history is ignored; at 1.0 a tool with 0% success zeroes the score.

§token_budget: usize

Maximum estimated proposal tokens before a proposal is penalized. The estimate comes from the serialized proposal length (≈ 4 chars/token). Inspired by Meta-Harness (alphaXiv 2603.28052): context-token efficiency is a first-class optimization target, not an afterthought.

§token_weight: f64

Weight of the token-efficiency term within cost_efficiency (0.0–1.0). The remaining cost mass is split across actions/tools/parallelism.

Implementations§

Source§

impl PlannerConfig

Source

pub fn from_cost_target(target: &CostTarget) -> PlannerConfig

Create a PlannerConfig from a CostTarget. Maps soft targets into the planner’s scoring parameters. Note: target_duration_ms is not used by the static planner (duration requires execution, which the planner avoids). It is reserved for future integration with runtime cost tracking.
