Tools
| Tool | Description | Behaviour |
|---|---|---|
| about | What Ringler is, what it costs, and how your person gets started (sign in once; $10 of credits free, no card). Call this first if you have no key. (No API key needed.) | Read-only |
| buy_credits | A checkout link your person opens to add credits by card ($20–$500). | Changes data |
| calendar_connect | A link your person opens to approve Google Calendar, so the agent can offer times and book. | Changes data |
| call | The agent dials the number, works the menu, hold and any bot until a real person answers, then rings your person's mobile and connects them. Spends credits ($0.30/min). If it hits voicemail it leaves a short message with a callback (default on; voicemail: skip to turn off). | Changes data |
| credits | Prepaid balance and recent usage. | Read-only |
| errand | The agent makes the call and does the asking itself: a reservation, an appointment, a question, a cancellation. It only rings your person if the other side needs them (a card, a decision). Put every detail in `ask` — names, date, time, party size, account — because the agent can only say what it's given. Spends credits. Leaves a message on voicemail by default. | Changes data |
| my_calls | Recent calls, newest first: when, who, outcome, summary, whether a transcript exists. | Read-only |
| my_messages | Instructions and notes your person left for you by calling their own line and telling the agent. Returns new ones (marks them read). Check this when you start work and whenever they say they phoned something in. Pass all:true for the recent history. | Read-only |
| my_mobile | The phone that rings when the agent has someone on the line for your person. | Changes data |
| my_number | Your person's own phone number, answered by their agent. Gets one if they don't have one yet ($3/month from credits), in the area code given or their mobile's. Confirm with them before the first buy. | Changes data |
| name_my_agent | Rename the agent (Ringo by default) and optionally pick a voice. Free. | Changes data |
| status | Your person's line, their agent's name, their mobile, calendar, who may reach them, balance, and the next thing to set up. Start here. | Read-only |
| tell_me | Send your person a spoken message through their agent. mode 'hold' (default) keeps it until they next call their line; 'call' rings their mobile now and the agent reads it, then takes anything they want to send back (it lands in my_messages). Use 'call' only when they asked to be rung, or for something that can't wait. Calls spend credits. | Changes data |
| transcript | One call in full: every line with speaker and time, the summary, and a one-hour recording link. | Read-only |
| who_can_reach_me | People the agent puts straight through when they call your person's line; everyone else gets a message taken. Pass `people` to set the list, nothing to read it. | Changes data |
