  "instructions": "pingwa is a two-way WhatsApp bridge to the account owner's own phone — a human in the loop for AI agents. There is no recipient field; messages always go to the key owner. Use `notify` to tell the human something happened (build done, task finished). Use `ask` to ask a question and BLOCK until the human answers on WhatsApp — they can reply with free text (steer you: 'use the other API', 'ship it') or tap one of up to 3 buttons; the reply comes back to you. Use `check_replies` to pull any inbound WhatsApp messages the human sent (poll for out-of-band instructions). Use `check_status` to see plan and remaining quota, and `upgrade` when quota runs out to get a Stripe link for the human to open (no password needed). Set PINGWA_KEY (a pw_... key) in the environment; without it, tools return an actionable error explaining how to get one.",
