## What the status means

Security status: **clear** · Forge verdict: not enough reports yet

Clear: no published advisory (OSV) matched 6.1.3 and no field report flagged it, as of 5 Nov 2026. Clear means no known pattern or advisory matched, not that a tool is safe.

Advisories are matched to one exact version. An advisory can only be matched once it is published, and field reports need 5 people, at least 2 verified, before a version gets a Forge Score ([methodology](https://theagentforge.io/methodology)).
