## Findings

- **warn** Annotations that disagree with the tool in `create_checkout_link` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "create_checkout_link" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "create_checkout_link" says "create": a word for a change.
```


## Changes things (1)

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

### `create_checkout_link`

- The name "create_checkout_link" says "create": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Returns a slashtel.com link with the chosen eSIM plan or top-up already selected. Share it with the user: they enter their email and pay on the site. For type 'esim' pass plan_id. For type 'topup' pass phone, operator_code and send_value from get_topup_plans.
```

## Only reads (5)

Looks things up and changes nothing. Claude Code: allow.

### `check_esim_status`

- The name "check_esim_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
For a traveller who already bought a Slashtel eSIM: returns data used, data left, plan size, expiry, status (not yet installed, active, used up or expired) and whether automatic top-up (Keep me connected) is on. Needs the email used at checkout AND the eSIM's ICCID (the long number starting 89, shown in the order email and in phone settings under the eSIM). Both must match the same order. Use it when someone asks how much data they have left or why their eSIM stopped working.
```

### `check_phone_compatibility`

- The description's first verb is "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Explains how the traveller can confirm their own phone supports eSIM and is unlocked before buying, with steps for iPhone and Android. Optionally pass the phone brand to get brand-specific steps. Use it before create_checkout_link when the user is unsure their phone will work; an incompatible or locked phone is the most common reason an eSIM cannot be installed.
```

### `get_esim_plans`

- The name "get_esim_plans" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Live travel eSIM plans for one destination: data (GB), validity (days), price (USD) and price per GB. Use an ISO-2 country code (e.g. TR, JP, US, GB) or a destination code from list_esim_destinations. Optional filters narrow the list.
```

### `get_topup_plans`

- The name "get_topup_plans" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Detects the operator of a mobile number and returns the live top-up options for it: what the recipient receives, validity where it applies, and the price in USD. The number must include the country code, e.g. +911234567890.
```

### `list_esim_destinations`

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

Description, as the server wrote it:

```untrusted-server-text
Lists every country and region Slashtel sells travel data eSIMs for (about 200 destinations), returning each destination's code, name, lowest live price in USD and number of plans. Use it to find the destination code when the user names a place, a region such as Europe or Asia, or is unsure what is covered. Optional search text filters by name. Skip this tool and call get_esim_plans directly when you already know the ISO-2 country code.
```
