## Tools
- arena_add_to_channels(position?: integer, channel_ids: integer|string[], connectable_id: integer, connectable_type: string) — Add an existing Are.na block or channel to one or more target channels without duplicating the underlying resource.
- arena_create_channel(title: string, metadata?: object, visibility?: string, description?: string) — Create a user-owned Are.na channel, closed by default, and return its stable numeric ID and generated slug.
- arena_delete_channel(channel_id: string) — Permanently delete one Are.na channel the authenticated user is allowed to destroy. This cannot be undone.
- arena_get_block(block_id: integer) — Get the details of one Are.na block by ID, including its subtype, content, source, creator, and metadata.
- arena_get_channel(channel_id: string) — Get an Are.na channel by numeric ID or slug, including visibility, counts, owner, and the current user's permissions.
