No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

### `analizar_acto`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Medios de defensa contra un acto del SAT, con sus plazos calculados.

tipo_acto: identificador del acto notificado (ver tipos_conocidos en la
  respuesta cuando no esté cubierto).
fecha_notificacion: fecha ISO (AAAA-MM-DD) en que se notificó el acto.
rfc: opcional. Si se proporciona, se consulta la situación del contribuyente
  para acotar la rama aplicable; sin él se devuelven todas las ramas.

```

### `explicar_plazo`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Cómo se cuenta el plazo de un remedio y qué disposición lo establece.
```
