Task keys encode security scoping and metadata in the Docket key format: {session_id}:{client_task_id}:{task_type}:{component_identifier} This format provides: - Session-based security scoping (prevents cross-session access) - Task type identification (tool/prompt/resource) - Component identification (name or URI for result conversion) )quoteunquote session_idclient_task_id task_typecomponent_identifierreturnc6t|d}|d|d|d|S)aBuild Docket task key with embedded metadata. Format: {session_id}:{client_task_id}:{task_type}:{component_identifier} The component_identifier is URI-encoded to handle special characters (colons, slashes, etc.).
