Struct PostToolUseHandler 

pub struct PostToolUseHandler {
    recall: Option<RecallService>,
    max_memories: usize,
    min_relevance: f32,
}

Handles PostToolUse hook events.

Surfaces related memories after tool usage.

Fields

recall: Option<RecallService>

Recall service for searching memories.

max_memories: usize

Maximum number of memories to surface.

min_relevance: f32

Minimum relevance score to surface.

Implementations

impl PostToolUseHandler

pub const fn new() -> Self

Creates a new handler.

pub fn with_recall(self, recall: RecallService) -> Self

Sets the recall service.

pub const fn with_max_memories(self, max: usize) -> Self

Sets the maximum number of memories to surface.

pub const fn with_min_relevance(self, min: f32) -> Self

Sets the minimum relevance score.

fn should_lookup(&self, tool_name: &str) -> bool

Determines if a tool use warrants memory lookup. Kept as method for API consistency.

fn is_prompt_save_tool(tool_name: &str) -> bool

Checks if a tool is a prompt save tool.

fn validate_prompt(&self, tool_input: &Value) -> Option<String>

Validates prompt content and returns any issues.

Returns a guidance message if validation issues are found.

fn extract_query(&self, tool_name: &str, tool_input: &Value) -> Option<String>

Extracts a search query from tool input. Kept as method for API consistency.

fn find_related_memories(&self, query: &str) -> Result<Vec<RelatedMemory>>

Searches for related memories.

fn empty_response() -> Result<String>

fn serialize_response(response: &Value) -> Result<String>

fn build_memories_response( tool_name: &str, query: &str, memories: &[RelatedMemory], ) -> Value

fn handle_inner( &self, input: &str, lookup_performed: &mut bool, memories_found: &mut usize, ) -> Result<String>

Trait Implementations

impl Default for PostToolUseHandler

fn default() -> Self
