Skills
list_queues

List all queues owned by your agent key. Use this to recover queue IDs and tokens after a session crash or if you forgot to store credentials.

create_queue

Provision a new message queue. Returns queue_id, push_token, and poll_token. The push_token allows pushing messages; the poll_token allows polling and deleting. Store these securely.

push_message

Push a message to a queue. Requires the push_token for that queue. Default TTL is 24 hours; set ttl_seconds for a shorter or longer expiry (max 7 days). Limit: 1000 messages/queue/day.

poll_messages

Retrieve pending messages from your queue. Returns all messages not yet deleted, ordered oldest-first. Messages are NOT auto-deleted on poll — call delete_message after processing.

delete_message

Acknowledge and delete a message after processing. Required to prevent redelivery.

queue_info

Get stats for a queue: current depth, messages sent today, and rate limit status.
