Checks & security
IntermediateLetting an agent write real code is only worth it if you can trust what comes out. bychat treats verification as part of building, not an afterthought — layered checks run on what the agent produced, and your code stays yours the whole way through.
Checks run on what was built, not what was promised
After a run, a check agent reads the actual result — the files that changed, the prompt you gave, and the project's own rules — and reports back. It catches the gap between what the agent said it did and what it actually did, so a confident-sounding answer never slips through unverified.
A second set of eyes by design
The review-of-two mode bakes verification into the build itself: two independent attempts, then a third agent that critiques both before writing the final result. Mistakes that survive one agent rarely survive a second one reviewing it — that's the whole point of the mode.
Security checks, not just correctness
Checks look past 'does it work' to 'is it safe' — leaked secrets, unsafe data access, missing auth, and risky dependencies get flagged before they reach your preview, let alone production. Your keys and credentials are never baked into the code an agent ships.
Your code, your control
Everything the agent does lands as a real commit on a real GitHub repo you own. There's no black box: you can read every change, roll any of it back, and walk away with the full history at any time. You're renting horsepower, not handing over your project.
You decide how strict to be
Quick prototype? Run a single agent and move fast. Shipping something that matters? Turn on review-of-two and a post-run check so nothing reaches users without a second opinion. The rigor scales to the stakes — you set the dial.
