### `get_current_drought`

- The name "get_current_drought" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get current drought conditions from the US Drought Monitor.

    Returns the percentage of area at each drought intensity level:
    - None: No drought
    - D0: Abnormally Dry
    - D1: Moderate Drought
    - D2: Severe Drought
    - D3: Extreme Drought
    - D4: Exceptional Drought

    Provide either a state abbreviation for statewide data or a county FIPS code
    for county-level detail. Omit both for national data.

    Args:
        state: Two-letter US state abbreviation (e.g. 'CA', 'TX').
        county_fips: Five-digit county FIPS code (e.g. '06037' for Los Angeles County).
    
```

### `get_drought_history`

- The name "get_drought_history" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get historical drought conditions over time from the US Drought Monitor.

    Returns weekly drought severity percentages for the specified area and date range.
    The Drought Monitor is updated every Tuesday, so data points are weekly.

    Args:
        state: Two-letter US state abbreviation (e.g. 'CA', 'TX').
        county_fips: Five-digit county FIPS code (e.g. '06037' for Los Angeles County).
        start_date: Start date in YYYY-MM-DD format. Defaults to one year ago.
        end_date: End date in YYYY-MM-DD format. Defaults to today.
    
```

### `get_drought_summary`

- The name "get_drought_summary" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get a national drought summary with total affected area percentages.

    Returns the current national overview showing what percentage of the US
    is experiencing each drought level (D0 through D4), plus the total area
    affected by any drought condition. Useful for getting a quick picture of
    drought conditions across the entire country.
    
```
