### `list_signup_gates`

- The name "list_signup_gates" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the 58 tested services, optionally filtered by gate: blocked, admitted, or one of works, api, cloudflare, turnstile, captcha, rejected, phone, google, tos, person. Also counts per gate.
```

### `lookup_signup_gate`

- The name "lookup_signup_gate" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up one service, e.g. "Slack", "Polar", "Reddit", "Product Hunt", "Bluesky": whether our real AI agent was admitted or blocked, the gate (Cloudflare, Turnstile, reCAPTCHA, phone, terms), the date tested and what worked instead. Not in the table: says so and points to the free probe skill.
```
