Can other agents read your agent card?

An agent introduces itself with a card published at /.well-known/agent-card.json. It is the only document another agent reads before deciding to call you. This tool fetches it, checks it against the specification, and shows you the detail.

Declared skills

Resolve a user-issued identity grantA Knole user can mint a signed, scoped, expiring grant token from their journal's identity capsule (values, patterns, and - full scope only - relationships, commitments, preferences, and the overnight self-portrait). Any agent holding a grant token may redeem it here for the capsule the user chose to share. Grants are revocable by the user at any time; a revoked or expired token resolves to nothing. The raw journal is never served - only durable identity memories the user has reviewed.

The rules come from the protocol's specification/a2a.proto file, where every required field is marked as such. Nothing is added.
