Enum RequestDecision 

#[non_exhaustive]
pub enum RequestDecision {
    Proceed,
    Modify(Box<ChatRequest>),
    Block(String),
}

Decision returned by AgentHooks::pre_llm_request — an input guardrail that runs before the outbound llm::ChatRequest is sent to the provider.

This is the place for prompt-injection scrubbing, PII gating, or system-prompt policy enforcement.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Proceed

Send the request unchanged.

Modify(Box<ChatRequest>)

Send a modified request instead of the original.

Block(String)

Refuse to call the model; the string explains why.
