## Findings

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

```untrusted-server-text
The server marks "generate_weather_log" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "generate_weather_log" says "generate": a word for a change.
```


## Changes things (1)

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

### `generate_weather_log`

- The name "generate_weather_log" says "generate": 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
Use this when the user wants weather history, historical weather data, historical weather by date and location, or a daily weather data download. Reads station observations and generates Excel and CSV weather logs with rain days for construction delay and thresholds. US only; up to five sites and 366 days, from 1900 through today UTC. Files expire in about an hour. Do not use for forecasts, current conditions or certified weather reports.
```

## Only reads (1)

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

### `find_weather_stations`

- The name "find_weather_stations" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user wants weather history, historical weather data, or past weather by zip code and needs reporting stations near a US city, ZIP or address. Returns date-specific coverage and distance for up to ten qualifying stations plus three with insufficient records. Dates default to the thirty days ending five days before today UTC; up to 366 days. Do not use for forecasts, current conditions or places outside the US.
```
