## What it does

The skill runs corporate due diligence as an ordered workflow. You start by writing down the target, the decision the work supports, the jurisdictions and what is out of bounds. Then it resolves the registration number in a named registry, because without one you have no subject. The trading name on the contract, the brand on the site and the entity liable in court are often three different companies, and every later finding attaches to the wrong one if you assume they match.

From there it maps group structure and beneficial ownership, pulls the officer list from the registry rather than the website, and checks each director's other and prior directorships. A separate layer covers the digital estate: domains, subdomains, registration dates, breach exposure of the email domain. The last pass screens litigation, insolvency, public procurement, sanctions, PEP and adverse media.

Everything stays passive. Reading DNS and certificate logs is fine; authenticating to or probing the company's own systems is not. Several steps lean on other skills from the same repository: `who-really-owns-it`, `find-anyone`, `recon-a-domain-passively`, `secrets-in-git-history`, `what-leaked-about-you`. Skip those and you do the matching stages by hand. The skill carries `disable-model-invocation: true`, so you invoke it explicitly.

## When to use it
- pin down which legal entity signs your contract
- vet a supplier before releasing payment
- trace ownership to a named beneficial owner
- compare registry officers against the team page
- surface litigation and insolvency at a director's prior companies

## Example prompts
- X-ray the company behind example.com before we sign the supply agreement
- Who actually owns the brand on this invoice? Resolve the entity and its beneficial owners
- Run due diligence on this counterparty: litigation, insolvency, sanctions, procurement

# X-ray a company

Take a brand, a website, or an invoice and produce a defensible picture of who you
are actually dealing with. Four layers — legal entity, people, infrastructure,
reputation and risk — worked in that order. Skipping the first ruins everything
after it: the trading name on the contract, the brand on the website, and the
entity liable in court are routinely three different things, and every later
finding attaches to the wrong one if you assume they match.

## Step 1 — Authorized scope

Write the target, the decision the work supports, the risk areas in scope, the
jurisdictions involved, and what is out of bounds. Read
[../../ETHICS.md](../../ETHICS.md). Corporate research on public filings is
broadly lawful and often mandatory, but two limits bite. Stay passive toward the
company's own systems — reading DNS and certificate logs is OSINT, authenticating
or probing is not. And named individuals inside the company are still data
subjects: an officer's directorships are fair game, their family is not.

**Done when** the scope note names the decision, risk areas, and jurisdictions,
and states that no interactive testing is authorised.

## Step 2 — Resolve the legal entity first

You are looking for a registration number in a named registry. Until you have
one, you do not have a subject.

| What you hold | Route to the entity |
|---|---|
| A website | Footer, terms, and privacy policy — statutory disclosure rules in much of Europe force the legal name and number onto the site; then confirm in the registry |
| A brand or trading name | Trademark registers give the registered proprietor; national registries index trading names against the registrant |
```
