Your Agent's Trace Probably Cannot Tell You Who Approved a Tool Call

LessWrong reports that the trace logs of many AI agent stacks often omit whether a tool call was authorized by a human or automatically approved by a policy, because downstream guard‑rail stages can dilute the original detector’s verdict without recording the change. The post highlights two public examples: the retire.js vulnerability scanner, which can disable TLS verification with a flag yet never notes the change in its JSON or CycloneDX reports, and Langfuse’s in‑app agent, which auto‑approves calls based on prefixes, allowlists or role policies without logging the approval source. Both projects later added logging of the approval source, but the underlying permissiveness of the features was left unchanged. The author urges developers to examine which safety checks might be overridden by lower‑level mechanisms and to ensure that every decision is fully observable in the logs.
