The situation

The post is a product introduction. The verbs are map, exploit, secure, probe, ship fixes for the team's review, and test again. The post does not include a resolved documentation URL.

Claims

Claim Status
Antigen is an offensive security agent Per post
It maps and probes an attack surface, then proposes fixes Per post
Fixes are shipped for a team's review Per post. This is the part the concept page treats as the gate
A retest checks that the issues were patched Per post
How probing or exploitation is done Not taught. Out of scope for this guide

What to steal

The loop with a person on the merge, and a retest that does not trust the agent's summary of itself. Record findings as pages so the next run sees status, not a fresh scan with no memory.

What to leave

Any request to expand "exploit" into steps. Any use against a system you are not allowed to test. The security index states that boundary for later sources too.
