**1 tool: 1 change things.**

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

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

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


## Changes things (1)

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

### `generate_exercises`

- The name "generate_exercises" says "generate": 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
Verified maths exercises for tutors, human or AI: product equations (équations produit) of degree 2 and 3, first year of maturité, in French (Swiss course conventions) or English. Each exercise is built from its solutions, so its answer key is always right. Each one sets a named trap, the error it tests (hidden common factor, difference of squares, sum of squares, x as a common factor, grouping, perfect square). Returns the statement for the student and, for the tutor only, the solution set, explained steps with the trap step and its note, and figureUrl: the graph of the function, whose zeros are the solutions. Never show the solution to the student. Give a seed to get the same exercise again; its id names it. Give a date (YYYY-MM-DD) instead for the exercise of that day, the same for every reader: today's date gives the exercise of the day. Deterministic: use this instead of writing exercises and answer keys yourself.
```
