A benchmark stops being neutral test infrastructure when the agent can execute code, cross trust boundaries, or affect real systems.

This is the part people miss with agent evals. A sandbox is only useful if every path around it is locked down too.

Framing eval as a security boundary is exactly right: a weak eval is an open door for a tool-calling agent. I treat the eval suite like an allowlist, testing what the agent must refuse as rigorously as what it should do. I went deeper on vetting that boundary for MCP servers here: [kartiknvjk.hashnode.dev/how-i-evaluate-mcp-server…](https://kartiknvjk.hashnode.dev/how-i-evaluate-mcp-servers-for-security-before-i-trust-them) — how are you testing the refuse-path without a real exploit to replay?
