An email arrives with three PDF attachments. Ninety seconds later a structured reply is in the same thread. Nobody opened the PDFs.

I built this for a client whose real version I can't share, so here is the pattern with the confidential parts removed: an n8n workflow, Claude reading the attachments by vision (not OCR — vision handles the scanned forms OCR chokes on), and a schema the reply has to fit before it's allowed to send.

The guardrails took longer than the happy path. They always do.

we recently shipped for CraftedStays most teams would've turned this into a straightforward feature walkthrough we took a different approach before touching a single frame, we went deep into the product not just what it does, but why it needed to exist that's the part clients rarely see- the research, the back-and-forth, and the process of truly understanding a product that's also how we onboard every client it's part of why our client onboarding success rate sits at 90% understanding the product deeply enough to explain it simply
