Router and baseline methodology for investigations into people, companies, or domains. It turns loose requests into falsifiable questions and sets collection plans.

## What it does

The skill acts as an intake router before running search tools. It forces you to write down five boundaries first: subject discriminators, objective, in-bounds items, out-of-bounds actions, and governing jurisdiction. If you cannot establish authorization and legal basis upfront, the instructions mandate stopping immediately.

Next, it structures the inquiry around an answerable question with clear stopping criteria. It builds a passive-first collection plan. The skill maps your starting selector to a dedicated workflow — such as `x-ray-a-company` or `recon-a-domain-passively`.

Every piece of evidence is graded immediately. The Admiralty NATO system assigns letters A to F for source reliability and numbers 1 to 6 for information credibility. An Analysis of Competing Hypotheses matrix then tests all working explanations against the collected evidence.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add UseOSINT/Skills --skill investigate-anything -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/investigate-anything/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/investigate-anything/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add UseOSINT/Skills --skill investigate-anything -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/investigate-anything/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add UseOSINT/Skills --skill investigate-anything -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/investigate-anything/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install UseOSINT/Skills investigate-anything
```

2. **Manually: put the files in place**
- File: `.github/skills/investigate-anything/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add UseOSINT/Skills --skill investigate-anything -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/UseOSINT/Skills --path skills/investigate-anything
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/investigate-anything/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add UseOSINT/Skills --skill investigate-anything -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/UseOSINT/Skills/tree/HEAD/skills/investigate-anything/SKILL.md

## When to use it
- define authorized scope and jurisdiction before investigating
- turn vague search requests into falsifiable intelligence questions
- build a passive-first collection plan mapped to sources
- route starting selectors to dedicated workflow skills
- grade evidence reliability using Admiralty source grading

## Example prompts
- I need to investigate an unfamiliar domain and contact email. Help me define scope and a collection plan.
- Where do I start with due diligence on this supplier invoice?
- Frame an answerable question and list initial pivots for this username.

  Start-here router and tradecraft baseline for any investigation into a person, company,
  domain, image or selector. Sets authorised scope, turns a vague request into an answerable
  intelligence question, writes a collection plan, picks the right workflow for the starting
  selector, and applies source grading and competing-hypothesis discipline. Use for
  "investigate this person or company", "do OSINT on X", "where do I start", or any
  open-source intelligence, due diligence, background or attribution task. Applies across due
  diligence, fraud, threat intelligence, journalism and compliance. Reference at

# Investigate anything

The front door. Everything downstream is faster than the thinking that should
precede it, which is why most bad investigations are not collection failures —
they are framing failures. You can run forty tools against a name and produce a
confident dossier on the wrong person. The work here is deciding what question
you are answering, what would count as an answer, and what would prove you
wrong.

## Core vocabulary

Used across every skill in this repo, defined only here.

- **Selector** — one identifiable data point: name, handle, email, phone,
  domain, IP, wallet, hash, plate, IMO, company number.
- **Pivot** — turning one selector into new selectors (email → breach record →
  reused handle → forum profile → real name). An investigation *is* a chain of
  pivots. Every pivot is also a chance to jump onto a different person.

## Step 1 — Authorized scope

Read [../../ETHICS.md](../../ETHICS.md), then write down five things:

1. **Subject** — the specific entity, distinguished from anyone with a similar
   name. Write the discriminators you will use ("the J. Okonkwo who is a
   director of company 09xxxxxx", not "J. Okonkwo").
2. **Objective** — see Step 2.
3. **In bounds** — selector types, sources, and whether interaction is allowed.
4. **Out of bounds** — the named things you will not do: logging into anything
   belonging to the subject, contacting them, family members, medical or
   religious data, and any selector unrelated to the objective.
5. **Jurisdiction** — whose law governs you, the subject, and the data. In the
   EU/UK, aggregating scattered public facts about a living person is processing
   personal data and needs a lawful basis and minimisation.

If you cannot state who authorized this and on what basis, stop. Not "proceed
carefully" — stop. An unauthorized investigation cannot be fixed later by a
good report.

**Done when** all five are written down and you can name the specific action
```
