## Changes things (4)

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

### `buscar_precio`

- 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
Precio de un medicamento en las farmacias de Chile, de más barato a más caro, con stock, y otras marcas con el mismo principio activo (registro del ISP). Acepta nombre comercial, principio activo o nombre con dosis. Los precios se reponen cada 6 horas: no los memorices.
```

### `farmacias_de_turno`

- 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
Farmacias de turno hoy y abiertas ahora en una comuna de Chile (directorio MINSAL), con dirección, teléfono y mapa.
```

### `ficha_medicamento`

- 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
Precio en cada farmacia, precio por unidad, principio activo, otras marcas y variación del precio en los últimos 30 días.
```

### `marcas_mismo_principio`

- 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
Todas las marcas que llevan un principio activo, de la más barata a la más cara, según el registro sanitario del ISP. Es donde está el ahorro grande: cambiar de marca rinde más que cambiar de farmacia. No reemplaza la indicación de un médico o químico farmacéutico.
```
