30-second pitch

KEYSTONE CI checks every code change (AI-written ones first) for tricks that weaken tests, and signs the verdict so nobody can swap the code afterwards.

We recorded 13 live checks, including 11 attack cases it had to refuse or flag, and every one matched. You can re-run them yourself without an account.

First email

Subject: is your AI agent fixing code or fixing tests?

Hi [first name],

Agents sometimes make a failing test pass by weakening the test. KEYSTONE CI catches that
and signs a verdict bound to the exact change.

LinkedIn connection note (under 300 characters)

Hi [name], we catch AI agents weakening tests in PRs and sign the verdict. Happy to show a demo.

One follow-up, three days later (then stop)

Hi [first name], one repo, 30 days, $500. Interested?

Live demo call script

1. Show the normal case
   Do: Open https://cainstudio.online/top25-keystone-ci-lab.html and run: Clean refactor
   Say: An ordinary change must pass, or nobody keeps the gate on.

2. Now the attack
   Do: Run: Agent skips the failing test
   Say: The most common agent shortcut: make CI green by skipping the test.

3. Now the attack
   Do: Run: Pull_request_target pwn request
   Say: Fork code runs with this repository's secrets and write token.

4. Let them check you
   Do: Send the kit link and ask them to run python3 verify.py --live on their own computer.
   Say: They don't have to take your word for any of this. That's the point.

5. Say the limit yourself
   Do: Tell them what the kit does not show.
   Say: Say it before they ask. It costs nothing and it earns trust.

When they push back

Can a clever change slip through?

Yes: it is pattern rules over the change, not a full analysis.

Is it live?

The offline verifier is live; engine 1.1.0 goes live with the next gateway deploy.

Why should I believe your numbers?

You shouldn't have to. Run the kit on your own computer: https://cainstudio.online/ihvrk-keystone-ci.html. It re-sends every request and compares the answers, using no code of ours.

What doesn't it do?

Written down here: https://cainstudio.online/top25-keystone-ci-limits.html

Are you SOC 2 or ISO certified?

No, we hold no certification. What we offer instead is evidence you can check yourself.

Has anyone independent tested it?

No third-party audit has been completed. The attack cases in the kit are our own. I'd rather tell you that now.

Who else uses it?

We are an early company. I can show you the product working and the evidence, not a customer list.

It found nothing. So we're safe?

No. It means none of its checks fired. It doesn't prove something is safe.

How much is it?

Sell KEYSTONE CI as the $500 30-day pilot on one repository.

The rules

Send each message yourself, one person at a time. No bulk lists and no automated sending.
Commercial email needs your real name, a real postal address and a way to opt out, and you stop when someone asks (US CAN-SPAM; many countries are stricter, so check yours).
Never change a number, invent a customer, or say certified, audited or guaranteed.
Only test a system the client owns or operates, after they confirm it in writing.
Your share is agreed in writing with FIRME AI CORPORATION before your first message (email vincent@firmeai.com). Nothing here promises income. Most messages get no reply; that is normal.
