## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `check_model`

- 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
Check whether an AI model identifier is deprecated, retiring, or has silently changed (price, context window, capabilities). Accepts any spelling a provider or SDK uses, e.g. 'gpt-4-turbo', 'azure/gpt-4.1-mini', 'claude-opus-4-1-20250805'. Call this before writing a model identifier into code.
```

### `check_models`

- 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
Check many model identifiers at once and report which are retired or scheduled for retirement. Use when auditing a codebase or config.
```

### `recent_changes`

- 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
Recent breaking changes across AI model APIs: price moves, context-window cuts, removed capabilities, removals. One entry per real upstream change.
```

## Only reads (1)

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

### `upcoming_retirements`

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

Description, as the server wrote it:

```untrusted-server-text
List models with an announced retirement date inside a horizon, soonest first.
```
