Struct UserPromptHandler 

pub struct UserPromptHandler {
    confidence_threshold: f32,
    search_intent_threshold: f32,
    context_config: AdaptiveContextConfig,
    recall_service: Option<RecallService>,
    llm_provider: Option<Arc<dyn LlmProvider>>,
    search_intent_config: SearchIntentConfig,
    capture_service: Option<CaptureService>,
    auto_capture_enabled: bool,
}

Handles UserPromptSubmit hook events.

Detects signals for memory capture in user prompts and search intent. When auto-capture is enabled, automatically captures memories when high-confidence signals are detected.

Fields

confidence_threshold: f32

Minimum confidence threshold for capture.

search_intent_threshold: f32

Minimum confidence threshold for search intent injection.

context_config: AdaptiveContextConfig

Configuration for adaptive context injection.

recall_service: Option<RecallService>

Optional recall service for memory retrieval.

llm_provider: Option<Arc<dyn LlmProvider>>

Optional LLM provider for enhanced intent classification.

search_intent_config: SearchIntentConfig

Configuration for search intent detection.

capture_service: Option<CaptureService>

Optional capture service for auto-capture.

auto_capture_enabled: bool

Whether auto-capture is enabled.

Implementations

impl UserPromptHandler

pub fn new() -> Self

Creates a new handler.

pub const fn with_confidence_threshold(self, threshold: f32) -> Self

Sets the confidence threshold for capture.

pub const fn with_search_intent_threshold(self, threshold: f32) -> Self

Sets the confidence threshold for search intent injection.

pub fn with_context_config(self, config: AdaptiveContextConfig) -> Self

Sets the adaptive context configuration.

pub fn with_recall_service(self, service: RecallService) -> Self

Sets the recall service for memory retrieval.

pub fn with_llm_provider(self, provider: Arc<dyn LlmProvider>) -> Self

Sets the LLM provider for enhanced intent classification.

pub fn with_search_intent_config(self, config: SearchIntentConfig) -> Self

Sets the search intent configuration.

pub fn with_capture_service(self, service: CaptureService) -> Self

Sets the capture service for auto-capture.

pub const fn with_auto_capture(self, enabled: bool) -> Self

Enables or disables auto-capture.

fn build_memory_context(&self, intent: &SearchIntent) -> MemoryContext

Builds memory context from a search intent using the SearchContextBuilder.

fn detect_search_intent(&self, prompt: &str) -> Option<SearchIntent>

Detects search intent from the prompt.

Uses LLM-based classification when an LLM provider is configured, otherwise falls back to keyword-based detection.

fn classify_intent(&self, prompt: &str) -> SearchIntent

Classifies intent using the appropriate detection method.

fn classify_without_llm(&self, prompt: &str) -> SearchIntent

Classifies intent without an LLM provider.

fn detect_signals(&self, prompt: &str) -> Vec<CaptureSignal>

Detects capture signals in the prompt.

fn check_patterns( &self, patterns: &[Regex], namespace: Namespace, prompt: &str, signals: &mut Vec<CaptureSignal>, )

Checks patterns for a specific namespace and adds matching signals.

fn extract_content(&self, prompt: &str) -> String

Extracts the content to capture from the prompt.

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

fn try_auto_capture( &self, content: &str, signal: &CaptureSignal, metadata: &mut Value, ) -> Option<CaptureResult>

Attempts to auto-capture a memory if enabled and conditions are met.

Returns the capture result if successful, and updates metadata with outcome.

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

Trait Implementations

impl Default for UserPromptHandler

fn default() -> Self

Returns the “default value” for a type.

impl HookHandler for UserPromptHandler

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

The hook event type this handler processes.

fn handle(&self, input: &str) -> Result<String>

Handles the hook event.
