# Create Task Comment

> Create a comment on a task.

Authorship is taken from the authenticated user — agent comments are
written by the agent runtime through a separate code path and are not
creatable via this endpoint.

Returns:
    Persisted comment with the server-populated id.

Raises:
    NotFoundError: If task not found.

        A markdown comment on a task.

        Comments live inside each organization's SurrealDB namespace —
        the namespace is the organization boundary, so no per-record
        ``organization_id`` field is carried on the row.

        Comments are first-class graph nodes connected to tasks via
        ``has_comment`` edges. Authorship is recorded as graph edges as well:
        user comments use ``authored_by_user`` and agent comments persist a
        dual ``authored_by_instance`` plus ``authored_by_type`` pair so that
        type-level attribution survives instance garbage collection.

        Attributes:
            id: SurrealDB record ID (populated by database).
            task_id: Task this comment belongs to.
            body: Markdown body of the comment.
            author_type: Whether the author is a user or an agent.
            author_user_id: User ID when ``author_type`` is ``user``.
            author_instance_id: Agent instance ID when ``author_type`` is ``agent``.
            author_agent_type_id: Agent type ID when ``author_type`` is ``agent``.
            edited: True after at least one update.
