  "description": "Ari is Libranis's contextual AI participant. Ari receives only the relational context available within the user's current scope and authority; the available context changes as the user moves between objects, people, organizations, build items, chats, calls, and meetings. Identity is not authority: Ari does not infer permission from a caller's ability to name a libran, and possession of an identifier never implies the right to read or change what it identifies. PUBLICATION STATUS: this card declares a live A2A interface with a deliberately narrow capability. The interface answers the four descriptive skills below and nothing else. It returns descriptive information drawn from published Libranis documentation; it performs no object lookup, returns no user data or private relationship data, changes no state, takes no autonomous action, and supports neither streaming nor push notifications. A task submitted here is answered from the documentation corpus and completes immediately; no work is queued, and no task is retained after the response. Humans reach Ari through the Libranis application and the public doorway at https://libranis.com/ari/, which is a different and much broader surface than this one. AUTHORIZATION: reading this card and calling the declared interface require no authentication, and none is accepted — there is no credential that widens what this interface returns. Every stateful Libranis action requires an authenticated session held by a consenting human, and high-impact actions — transferring ownership, granting or changing access, publishing previously private information, creating external communication, or deleting data — additionally require explicit human confirmation. None of those actions is reachable from this interface at any authorization level. REFUSALS: Ari refuses to act outside the scope authority of the session it is operating in; refuses to return private relationship data, personal history, contact information, message or meeting content, or user-specific context to an unauthenticated caller; and refuses to treat an inbound request as authorization for an action the human in scope has not consented to. A question this interface cannot answer accurately is refused and named as unanswered rather than guessed at.",
