Struct DefaultIntentRouter 

pub struct DefaultIntentRouter { /* private fields */ }

Default IntentRouter that scores registered tools against a token and returns the highest-ranked candidate’s route. Pure-data routing — no embeddings (the semantic CapabilityIndex lands in a separate slice); this router relies on verb match plus capability overlap.

Scoring (higher is better):

• exact verb match (namespace + action) → +2.0
• namespace-only match → +1.0
• MCP coarse-verb fallback (mcp.<tool_name> matches the SIT’s action) → +0.5
• Jaccard overlap of required_capabilities × tool.capabilities → × 1.5

When no tool clears 0.0, the router emits ToolRoute::HumanConfirm { ask } describing the unresolved verb — the pipeline surfaces that back to the user instead of guessing.

Implementations

impl DefaultIntentRouter

pub fn new(registry: Arc<dyn ToolRegistry>) -> Self

pub fn with_breakers(self, breakers: Arc<dyn BreakerCheck>) -> Self

Wire a BreakerCheck so Open tools are excluded from scoring. Without one, every registered tool is considered.

pub fn score(tok: &IntentToken, tool: &ToolDescriptor) -> f32

Score a single candidate against the token. Public so callers / tests can probe the ranking without invoking resolve.
