Evidence, proof and selling tools for CAIN Swarm Guard

Level 1 Beginner: understand it

CAIN Swarm Guard is a one-line Python decorator around an AI agent's tools. Before a tool runs it checks an allowlist, the arguments and the risk; a risky call stops before the tool body is reached. When one agent hands work to another, the second can only receive equal or less authority.

Think of it like this: A guard at each door who checks the list and looks in the bag, and a rule that nobody can lend out a key they don't hold.

Read the full plain-English explanation: CAIN Swarm Guard, explained.

• I read the explanation above.
• I can say what it does in one sentence, without notes.

Level 2 User: see it work

Run it live: open the live demo. Before each result, guess what will happen. These are checks it must pass:

• A listed, low-risk read: On the allowlist and low risk: the tool runs.
• A tool nobody listed: Default-deny: an unknown tool does not run.
• Listed, but it deletes all users: Being on the list does not excuse a destructive action.
• Listed shell tool, piped download: curl piped to bash is stopped by its arguments.
• A payment declared HIGH risk: High risk waits for approval.
• Handoff with narrower authority: A sub-agent may receive less authority.

• I ran the live demo.
• I can explain what one of these checks shows.

Level 3 Verifier: prove it yourself

This is the skill that sets you apart: you don't have to believe us, and neither do your customers.

1. Install Python 3 if you don't have it (python.org/downloads).
2. Download the kit and unzip it.
3. Open a terminal in that folder. On Windows, click the folder's address bar, type cmd and press Enter. On a Mac, right-click the folder and choose New Terminal at Folder.
4. Run python3 verify.py (on Windows, python verify.py). It checks the seal without the internet.
5. Run python3 verify.py --live. It repeats every check from your own computer.
6. Try to cheat it: open transcript.json in a text editor, change one character, save, and run python3 verify.py again. It must now say FAIL. Unzip a fresh copy afterward.

• I ran the kit's check on my own computer.
• I changed a file and saw it fail.

Level 4 Expert: know the edges

An expert knows what a product does not do, and says it first. That is what makes a buyer trust you.

• It protects only tools you wrap; an agent that can reach a tool another way is not stopped.
• Argument checks recognize patterns. A harmful call worded in an unfamiliar way can pass.
• It is a Python decorator. Other languages go through MCPGate instead.
• No plug-in ships for a particular agent framework; you wrap the tools the framework calls.
• Our own test cases; no third-party audit.

You can say

• A risky tool call stops before the tool runs.

Never say

• "Unbreakable" or "stops every attack".

Read the questions real buyers send, with honest answers: answers to buyer questions.

• I got every quiz question right without looking.
• I can name one thing it does not do.
• I explained it to a friend, and they understood it.

Level 5 Seller: put it in front of a customer

1. Copy, paste, send: the shortest route, no technical skill needed.
2. Who buys it and where to find them.
3. The sales conversation, then the offer and the close.
4. The rules: read these before your first message.
5. Selling tools with this product's evidence built in: pitch, emails, call script, objection answers, one-pager.

• I read the rules.
• I sent my first personal message.
