## Findings

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

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

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

- **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,"openWorldHint":false}; The name "create_checkout_link" says "create": a word for a change.
```


## Changes things (2)

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 the link where a person pays for Elite (monthly or yearly). Payment happens on a Stripe page (card, Apple Pay, or Link) after the person signs in. Agents never enter card details. Most people should start with start_trial instead.
```

### `start_trial`

- The name "start_trial" says "start": 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 the link a person opens to start the free Elite trial. The person creates the account and accepts the Terms themselves. No card is needed. This tool does not create an account or send email.
```

## Only reads (3)

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

### `get_features`

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

Description, as the server wrote it:

```untrusted-server-text

```

### `get_languages`

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

Description, as the server wrote it:

```untrusted-server-text
Languages a SwiftPrism Elite member can read headlines, Deep Insights™, and the Economic Calendar in, and hear Headline Voice in.
```

### `get_plans`

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

Description, as the server wrote it:
