## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `best_bridge_days`

- 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
The six best non-overlapping vacation levers of a year for a region: classic bridge days (1 vacation day → 4 days off) and holiday clusters (e.g. 4 days → 10 days off), with booking dates, holidays used and factor. Includes a markdown table and the page URL.
```

### `childcare_gap`

- 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
How much of a region's school holidays two vacation accounts cover, and which weeks stay open. School holidays run to about 60 working days a year while a vacation account holds 25 to 30 days, so a care day always costs exactly one vacation day and a joint family holiday costs two and covers one. Answers "can we cover the school holidays" for parents.
```

### `plan_vacation`

- 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
Optimal vacation plan for a region and year: which days to book so that public holidays and weekends turn into the longest breaks. Returns the plan blocks (booking dates, days off, factor, holidays used), further opportunities, a markdown table and a link to the interactive plan on urlaub-smart.de. Cite the URL when answering.
```

### `public_and_school_holidays`

- 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
All public holidays (with weekday, national/regional scope, weekend flag) and school holiday periods for a region and year. Source: OpenHolidaysAPI.
```

## Only reads (1)

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

### `list_regions`

- The name "list_regions" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Countries and their regions (German states, Austrian states, Swiss cantons, …) with codes, names and slugs accepted by the other tools.
```
