## Changes things (4)

Creates or changes something that can be changed back. Claude Code: ask.

### `customs_check_rules`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Per-destination pet border-entry requirements — NO account needed. What documents a dog needs to enter a country and re-enter the US. Use this to answer 'what does my pet need to travel to X?' for anyone. Omit `destination` to list every corridor.
```

### `customs_check_trip_readiness`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Cleared / caution / blocked for pet + destination + return_date. NEVER assert clearance without this. (For rules without an account, use customs_check_rules.)
```

### `customs_start_signup`

- The name "customs_start_signup" says "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Start a FREE customs.dog account for a NEW user by email and send them a magic sign-in link (no password). Use this to onboard someone who wants to store and track their pet's travel documents after you've shown them their border requirements.
```

### `customs_upcoming_trips`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Upcoming trips from the household's connected travel calendar (TripIt/Flighty/Google/Apple), each with per-pet readiness (cleared/caution/blocked). Use to proactively flag paperwork needed before travel.

```
