No check matched anything in these tool definitions.


## Changes things (5)

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

### `area_rents`

- 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
Median weekly rent of new bonds lodged in the latest quarter, all dwellings together, with the bond count and the change on a year before, for one state per call: NSW by postcode or council (NSW Department of Communities and Justice), QLD by suburb or council (Residential Tenancies Authority), WA by locality (calculated by DwellDelta from the Government of Western Australia's bond records). Each CC BY 4.0. area or council names the place the question is about; with neither, the answer is the state's own figure. The figures are new-bond medians, not advertised rents. Each state measures in its own way, so the states are not one series: their figures cannot be added together or compared as one. Each answer states its quarter, its source line and the source's limits. Victoria is in vic_rents. For NSW and QLD, dwelling_type or bedrooms (or both) give the publisher's figure for that kind of home instead - a two-bedroom unit, a three-bedroom house. Only combinations the publisher reports are answered: one with no published median is said to have none, and neither another area's figure nor the all-dwellings figure stands in for it. Many such figures rest on few bonds. WA has no figures by dwelling type or bedrooms.
```

### `data_sources`

- 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
The sources behind DwellDelta's figures, their licences, and what it cannot answer (what any one home sold for, the rent of a single street or home, rents by area outside NSW, Victoria, Queensland and WA, sale prices outside NSW, advice).
```

### `market_indicators`

- 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
Latest observed Australian property market indicators - RBA cash rate, unemployment, wage growth, rents by capital city, new housing lending, lending standards and arrears, dwelling approvals and completions - each with its period, source, licence and limits. Observed figures only; none is a forecast. geography, if given, narrows the answer to the figures for one place (e.g. NSW, Australia, Sydney).
```

### `nsw_sale_prices`

- 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
Median sale price of the dwellings sold in the latest reported quarter in NSW, with the quartiles, the number of sales and the change on a year before, by postcode or council and by dwelling type - all dwellings, non_strata (separate houses) and strata (units, town houses, villas). From the NSW Department of Communities and Justice's Rent and Sales Report (CC BY 4.0). area or council names the place the question is about; with neither, the answer is the state's own figures. These are medians of homes sold: not asking prices, not valuations, and never what any one home sold for or is worth. A line marked UNUSUAL was set by a few very large sales or by many sales at one identical price, and is not a going price. A total noted as mostly a marked row's sales may be moved by them, and the file shows nothing more about it. A line with any other mark or note is not a going price either, and the file does not say why. Each answer names the dwelling type, the quarter and the source line, and states the limits.
```

### `vic_rents`

- 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
Victorian rents from Homes Victoria's Rental Report (CC BY 4.0): the median weekly rent of new leases in the latest quarter, how many leases it rests on, and the change on a year before, for 146 suburb groups and 13 regions. suburb_group (part of a name works, e.g. "Brighton") or region narrows the answer to the place the question is about. The figures are new-lease medians, not advertised rents, and each answer states its quarter, its source line and the source's limits.
```

## Only reads (1)

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

### `rent_check`

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

Description, as the server wrote it:

```untrusted-server-text
Compares a weekly rent, and any proposed new rent, with how the ABS rents index for the tenant's Australian capital city has moved since the lease began. city is one of the eight capital cities, whose index is city-wide, not suburb-level. The answer is information, not advice, and carries the months compared, the source and the index's limits.
```
