summary: >-
  Mention runs an OAuth 2.0 authorization-code flow but defines NO scopes. There is no scope
  parameter on the authorize request, no scopes list in the token response, and no permissions or
  scopes reference page anywhere in the documentation. A granted token carries full access to the
  authorizing account — the same access the account's own token has. This file records that as a
  measured zero rather than omitting the artifact.

  note: >-
    Authorization in Mention is expressed through resources, not scopes. The Share object decides
    which accounts can see which alert and carries a per-share permissions map (edit, delete) and a
    role; the Alert carries its own permissions map (edit, share, list_tasks, list_logs); the Account
    carries a permissions map and a team-member kind of admin, user or restricted. Some actions are
    marked admin-only in the reference (setting a mention favorite or trashed, deleting another
    account's share). None of that is exposed to the OAuth layer, so a client cannot request reduced
    access — it is all-or-nothing at the token, then filtered per resource at the server.

agent_implications:
  - >-
    An agent given a Mention token has full read AND write authority over the authorizing account:
    it can delete accounts, delete shares (which destroys alerts), and create or modify anything.
    There is no least-privilege token to issue instead.
  - >-
    Constrain at the agent layer rather than the token layer. See
    agentic-access/mention-agentic-access.yml for the per-operation execution contracts.
