## Findings

- **warn** Mentions of other tools or servers in `municipality_search` ([tool-shadowing](https://anlyon.dev/methodology#tool-shadowing))

```untrusted-server-text
The description contains "every other tool", wording about other tools or servers.

description: "...s for each match. The BFS id is the key every other tool here takes."
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `commute_cost`

- The input addresses people (input.to): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Estimates the monthly cost in CHF of commuting between two Swiss places, as a transit-pass estimate priced from Swiss regional fare-zone data. Some pricing regimes are approximations rather than an exact tariff.
```

## Changes things (2)

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

### `favorable_municipalities`

- 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
Ranks municipalities that are cheaper than, or within CHF 1000/yr of, a stated current home, by annual tax saving — municipalities near-identical in cost are included deliberately, not filtered out. Answered from cached figures only, so the ranking may be partial; the response states how many candidates were covered. Pass `near` (a town or station name) and `radiusKm` to keep only places around where the household lives or works; an unrecognised place is reported, not silently ignored.
```

### `rent_benchmark`

- 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
Reports the Swiss Federal Statistical Office's average monthly rent for a municipality, optionally for a given apartment size in rooms. BFS does not publish rent below canton level except for 10 named cities, so the figure may describe the CANTON rather than the municipality itself; the response states which.
```

## Only reads (5)

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

### `commute_time`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the public-transport journey time in minutes between two Swiss places, using the national timetable.
```

### `listing_search`

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

Description, as the server wrote it:

```untrusted-server-text
Lists apartments currently advertised in one municipality, cheapest first, with the local median asking rent. Indicative figures for browsing only: they come from a portal feed and are not verified against the listing page.
```

### `municipality_detail`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the tax picture for one municipality relative to a stated current home: the annual difference, the tax multiplier, and the multi-year trend where past years are known.
```

### `municipality_search`

- The name "municipality_search" says "search": a word for reading.
- Findings: warn tool-shadowing

Description, as the server wrote it:

```untrusted-server-text
Finds Swiss municipalities by name fragment or postcode. Returns the BFS id, name, canton and postcodes for each match. The BFS id is the key every other tool here takes.
```

### `tax_lookup`

- The name "tax_lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Calculates the annual Swiss income tax for one municipality and one household profile, split into federal, cantonal and municipal parts. The figures come from the federal tax administration's calculation for the given gross income.
```
