## Findings

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

```untrusted-server-text
The server marks "create_worksheet" 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_worksheet" says "create": a word for a change.
```


## Changes things (1)

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

### `create_worksheet`

- The name "create_worksheet" 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
Makes a new printable math worksheet for one topic as a PDF, with a separate copy that includes the answer key. Every call gives a fresh version of the problems. Topics are identified by the topic ids that the topic search returns.
```

## Only reads (1)

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

### `search_worksheets`

- The name "search_worksheets" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Finds Sigma Prep math worksheet topics (Pre-Algebra, Algebra 1, Geometry, Algebra 2, Precalculus, Calculus, Statistics) that match a request in plain words. Returns each topic's id, the difficulty levels it offers, its question types and its page on sigmaprep.io.
```

## Claude Code permissions
