agent-evaluation-lab

A set of workflows for checking prompts, skills, red-team tests, and an agent’s behavior. Red-team testing deliberately probes for failures or unsafe responses.

In plain words
What is it for?
Use it to evaluate prompts and skills, run behavior tests, and investigate how an agent responds to challenging inputs.
Why use it?
It helps reveal whether an agent follows instructions and behaves correctly before relying on it in real work.

Grade A, and why

agent-evaluation-lab scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
