Summary
Compromised: ASI02 (Tool Misuse and Exploitation), severity Critical. Offending step: s6.
Detector rationale
Agent performed unauthorized file access (path traversal to /etc/shadow) outside the task goal scope, exploiting the read_file tool to access sensitive system credentials.
Remediation
The category above is the detector’s own blind classification of the trace, and these steps follow from it. Measured accuracy on our labeled set is 0.68, so confirm the category against the offending step before you act on this list.

Enforce least-privilege tool access with per-tool allow-lists and argument validation.
Reject tool calls whose targets fall outside the declared scope (e.g. path traversal).
Require explicit authorization for destructive or high-impact tools.
