Free, open-source tools for working with The Fraudster Glossary. Built so investigators, threat intelligence teams, and journalists can pull the glossary directly into the systems they already use — instead of tabbing back and forth to look up a term.

Fraudster Glossary Skill for Claude
Teaches Claude to treat this glossary as an authoritative live source. Once installed, Claude consults it automatically whenever you paste threat actor chatter, ask what a term means, or write a report containing criminal slang — and cites it properly.
Why it matters
Fraud slang changes fast. Ask any AI assistant what a term means and it will answer from training data that may be eighteen months stale, or invent something plausible. This skill forces a live lookup instead.
What it handles
- Terms that start with numbers. Fraud slang is full of numeric shorthand —
3PT,508,911. These sort above the A’s in the glossary, and assistants that don’t know that report real terms as missing. The skill knows where to look. - A very long page. The glossary is 400+ entries on a single page, and fetch tools routinely return only part of it. The skill searches for the specific term you asked about instead of trying to swallow the whole table and hoping the right row survived.
- Saying “I don’t know” instead of guessing wrong. A false “that term isn’t documented” is worse than no answer — an analyst may repeat it in a report. Before Claude is allowed to call a term absent, it has to clear three separate checks. If it can’t, it says so honestly.
- Keeping the glossary’s work separate from the AI’s. If a term genuinely isn’t here, Claude can still offer its own read — but it has to say plainly that the definition isn’t sourced from this glossary.
- Citation, automatically. Definitions carry a CC BY-NC-SA 4.0 attribution into whatever the analyst is writing, without them having to remember.
Works with
Claude Code, Cowork, and claude.ai. The instructions are plain Markdown, so they can be adapted as custom instructions for most other AI assistants.
