pub fn tool_conditional_execution(name: &str, args: &Json) -> Result<()>

Run only the tool conditional-execution guardrail chain.

This evaluates whether a tool call should be allowed to proceed without invoking request intercepts or execution. Each evaluated guardrail emits an automatic guardrail scope start/end pair for observability.

Parameters

  • name: Tool name used when resolving the guardrail chain.
  • args: Raw tool arguments to validate.

Returns

A Result that is Ok(()) when all guardrails allow execution.

Errors

Returns FlowError::GuardrailRejected when a guardrail blocks execution, or any error raised by the guardrail chain itself.

Notes

This helper is useful for preflight checks when the caller needs the rejection result without starting a tool span. Guardrail scopes are still emitted for the conditional checks themselves.
