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

### `compare_stays`

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

Description, as the server wrote it:

```untrusted-server-text
Compare two to four distinct Guestit listings for the same dates and number of guests. Retains missing or unavailable listings. Prices include applicable fees and do not hold inventory or confirm a booking.
```

### `resolve_destination`

- The name "resolve_destination" says "resolve": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find the Guestit destination for a place name before searching stays. Pass the place alone, such as Åre or Stockholm. Returns only places with Guestit stays, at most one. When nothing matches, ask the user about a larger place nearby.
```

### `search_stays`

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

Description, as the server wrote it:

```untrusted-server-text
Search public Guestit accommodation using a location_id from resolve_destination. Refine by resending the full filter set. Each stay is a short card; read house rules and the cancellation policy with stay_details or compare_stays before recommending one. Prices are estimates for the supplied dates and guests, with no inventory hold. Stays that fail the live check for those dates are left out, so a page can hold fewer than its limit. Nightly-rate filters use indexed average rates in SEK, not final stay totals. Pagination counts reflect the search index; current public rows may be fewer. Complete booking on the returned Guestit website link, which opens with the dates and guests filled in.
```

### `stay_details`

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

Description, as the server wrote it:

```untrusted-server-text
Read a public Guestit listing, house rules, cancellation policy and dated price estimate. Supply both dates and the guest count for an estimate. Fees shown are already included in the total. This does not reserve inventory or take payment. Open website_url to continue on Guestit; it opens with the dates and guests filled in.
```
