## Findings

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

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


## Changes things (2)

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

### `create_trip_plan`

- The name "create_trip_plan" 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
Erstellt einen generischen Tagesplan, Budgetrahmen, Last-Minute-Prüfpunkte und eine direkt zu öffnende Blitzbuchen-Planungs-URL. Nutzt nur deine Eingaben, keine Livepreise oder Ortsdaten.
```

### `last_minute_checklist`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Erstellt eine Checkliste mit künftigen T-72-/T-24-Terminen sowie priorisierten fälligen oder verpassten Schritten, die jetzt erledigt werden sollten.
```

## Only reads (1)

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

### `compare_travel_offers`

- The name "compare_travel_offers" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Vergleicht zwei bis fünf vollständig nutzerseitig eingegebene Reiseangebote einschließlich Gebühren und Tageskosten. Gibt einen optionalen Link zurück, um diese Angebote auf Blitzbuchen weiterzubearbeiten. Es werden keine externen Preise abgerufen.
```
