Struct AutoClassifier 

pub struct AutoClassifier {
    pub tracker: DenialTracker,
    /* private fields */
}

LLM-based classifier that decides whether a tool call should be auto-approved in PermissionMode::Auto.

Fields

tracker: DenialTracker

Denial tracker for safety limits.

Implementations

impl AutoClassifier

pub fn new(provider: Arc<dyn LlmProvider>) -> Self

Create a new classifier backed by the given provider.

pub async fn classify( &mut self, tool_name: &str, args_summary: &str, transcript_snippet: &str, ) -> Result<(bool, String)>

Classify whether a tool call should be blocked.

Arguments

• tool_name — name of the tool being called.
• args_summary — JSON string summary of the arguments.
• transcript_snippet — recent conversation context.

Returns

Ok((block, reason)) — block is true if the tool should be denied.

Behaviour

• If the denial tracker is over limit, returns (true, "...") without calling the LLM.
• On JSON parse error, defaults to (false, "classifier parse error...") (conservative: err on the side of allowing).
