PolicyValidator

zeph_tools::adversarial_policy

Struct PolicyValidator 

Source 
pub struct PolicyValidator { /* private fields */ }
Expand description

Validates tool calls against plain-language policies using an LLM.

Implementations§

Source§

impl PolicyValidator

Source

pub fn new( policies: Vec<String>, timeout: Duration, fail_open: bool, exempt_tools: Vec<String>, ) -> Self

Create a new validator with pre-parsed policy lines.

Source

pub async fn validate( &self, tool_name: &str, params: &Map<String, Value>, llm: &dyn PolicyLlmClient, ) -> PolicyDecision

Validate a tool call against the configured policies.

Returns PolicyDecision::Allow, PolicyDecision::Deny, or PolicyDecision::Error (behavior on error controlled by fail_open).

Source

pub fn fail_open(&self) -> bool

Whether an Error decision should allow (true) or deny (false).
