Why badge-accept is rated Medium
This tool creates or modifies user profile data (badge list) in a reversible manner. The user can remove badges later, making it Write rather than Destructive. Severity is medium because while it modifies user-controlled profile data, the blast radius is limited to cosmetic/identity metadata on a social platform without financial or access control implications.
From the tool's definition Tool description explicitly states "Accept a badge and add it to your profile badges" and "Updates your profile badge list", indicating modification of user profile data via NIP-58 kind 30008.

badge-accept stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Nostr Bray, apply this rule, and every badge-accept call is checked against it from then on.
