SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

HybridClaw’s fax-send skill eliminates manual faxing by converting supported documents or generated PDFs into provider-ready outbound fax requests and by routing inbound fax PDFs into downstream document workflows.

Core Features & Use Cases

  • Guarded outbound fax sending: Build and dispatch Sinch Fax EU-resident API requests with explicit operator approval and per-page usage accounting.
  • Delivery status classification & audit events: Poll Sinch delivery state, classify provider statuses into delivered/failed, and emit structured audit intent for persistence.
  • Inbound fax-to-email handoff recipe: Treat inbound fax PDFs as email attachments and hand them off to existing document workflows (e.g., DATEV Belegtransfer, storage, client records).

Quick Start

Fax the signed contract to +49 89 1234567 using the stored Sinch project id and my operator approval, without asking me again.

Frequently Asked Questions about fax-send

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate sending a PDF file through a fax API?

To automate fax sending, this skill builds provider-ready outbound fax requests through the Sinch Fax adapter. It accepts a local PDF file upload, an HTTP(S) content URL, or generated text converted to a PDF for delivery.

Can I check fax delivery status and create audit events for failed transmissions?

Yes, you can check fax delivery status by polling the Sinch provider state. The skill classifies provider statuses into delivered or failed categories and emits structured audit intent for persistence and retry handling.

Does the fax API workflow require operator approval before dispatching?

Yes, the fax API workflow enforces explicit operator approval before dispatching outbound requests. It also performs stored-secret injection to securely authenticate Sinch Fax EU-resident API requests.

How do I route inbound fax-to-email PDFs into downstream document workflows?

You route inbound fax PDFs by treating them as email attachments and handing them off to existing document workflows. This inbound handoff recipe integrates received PDFs into storage or client record systems.

What format should phone numbers be in for validating outbound fax requests?

Phone numbers must be in E.164 format for outbound fax requests. The skill validates inputs like E.164 numbers and HTTP(S) content URLs to ensure provider compatibility before building the fax request.

Do I need a usage accounting system to track fax page costs?

Yes, you need usage accounting to track fax page costs. The skill supports page-based cost measurement using UsageTotals with fax-page units, applying per-page usage accounting to outbound fax transmissions.
