Vouch request: AdemVessell

[AdemVessell]

What do you want to work on?

I'd like to see if I could help out with #3017 if it still needs a contributor.
I really like working on things that involve permissions, credentials and access etc.

Why this change?

Agents are using real tools and real creds and I'd love the chance to help making the security boundaries surrounding all this clear and testable. Cred use etc needs records without exposure.
