About Ferrule Lab

We are an independent AI studio in Vancouver. We build AI tools and automations people can trust with real work.

Why “adversarial”

Every unit of work goes to a reviewer whose job is to break it. The reviewer is a separate AI agent that sees only the artifacts. Work goes back until it passes.

Before that, a sandbox really compiles, lints and tests it. Known-bad patterns are refused by deterministic gates, so catching them does not depend on someone noticing.

One of our own gates failed. Here is what we did.

It passed 44 green tests. An independent review then found it silently skipping functions whose security intent was missing or misspelled.

We changed it to block anything it cannot classify. The test count went from 44 to 51.

Why we state our limits

A limit you find out about later is a limit you paid for.

So each page says what is built, what is not, and what our test numbers do and do not prove.
