For identity, connection, or principal-switch questions, use connection guidance and an exposed identity read when needed. For a small direct action such as reading a file or sending an already approved message, use shared workflows without loading unrelated skills. Load optional capabilities only when needed. A combined request may require more than one workflow; preserve its scope and avoid duplicate reads or writes.
These are general entry points, not a new authentication mechanism or an always-running agent. Never imply a principal switch or background workflow happened merely because a skill was invoked.
For identity or workspace selection and switching, follow Connection, workspace and identity. Use the discovered overview/reconnection tools; older catalogs may offer
manage_connection.
