What actually lands in your inbox

Every dataroom is a pile. No two are shaped alike.

A seller hands you a folder and calls it organized. Inside: scanned leases, a revenue workbook with its own tab names, an offset map buried three folders deep. There is no schema. The one thing you can't do is assume the next dataroom looks like the last.

"here's the dataroom"
The loose structure underneath

No standard shape — but a shape it's reaching for.

A dataroom is unstructured, not random. To sell an asset you have to define it, so one thing is always there. The rest come and go. The skill hands Claude that target — what to look for, and where it tends to hide — not how to read the file once it's found.

Required · the floor
The asset being sold
You cannot sell what you can't name. Wells, units, or a mineral tract — the one thing every dataroom must pin down.

Where the skill stops

Give it a target. Don't teach it to read.

Claude already knows how to open a PDF and parse a spreadsheet — that's the model's job, and it's good at it. The skill's job is the part the model can't guess: the shape of an oil & gas deal and where the pieces live. Everything above the boundary; nothing below it.

The skill supplies The structure to aim for
  • The target skeleton — asset first, then the optional layers
  • Where each piece tends to hide in a dataroom
  • What "done" looks like — a resolved, checkable asset definition
  • Domain sense: what a division order is, why the PSA exhibit matters
the part that's specific to oil & gas
The skill leaves alone How to read the file
  • Extracting text from a PDF or a scan
  • Parsing tabs, merged cells, and raw exports
  • Reading a table with no header row
  • OCR, layout, format quirks — the model handles all of it
the part Claude already does well

Point Claude at the pile and it maps the mess onto the skeleton — asset resolved, statements matched, offsets and interest attached. That structured package is exactly what the forecast and the economics were waiting for.
