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

### `detalle_tramite`

- 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
Devuelve la ficha de un trámite por su código `tipo` (de listar_tramites): descripción, datos que pide el formulario y enlaces. El precio vigente está en url_informacion.
```

### `listar_tramites`

- 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
Lista los trámites que Zertidox ofrece hoy en España (certificados oficiales, informes inmobiliarios y documentos jurídicos), con su enlace de información y de solicitud. Admite un filtro de texto opcional.
```

### `que_tramite_necesito`

- 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
Dada una necesidad en lenguaje natural (p. ej. «certificado de antecedentes penales para trabajar con menores» o «valorar mi piso»), devuelve hasta 5 trámites de Zertidox que encajan, con su enlace. Orientación informativa, no asesoramiento jurídico.
```
