Agent Identity

Agent identity is an AI interface design pattern that gives every agent a stable, addressable name, version, and declared capability set the user can point at, distinguishing which agent did what when multiple are in play. This UX pattern turns agents from anonymous background processes into named actors with lineage: the same agent yesterday is the same agent today, its behavior is attributable to a specific version, and its capabilities are the ones listed on its profile, not whatever the model happens to do this session. Agent identity is the prerequisite for every other trust pattern in the framework (attribution, audit, revocation, responsibility) because those patterns have nothing to bind to without a stable referent. In mature agent ecosystems, identity is the primary key: every log line, every permission grant, every artifact the agent produces traces back to it.
