Problem
My AI agents keep breaking the build
Because broken code never reaches your trunk. Every change your agents submit passes through a gate before it can merge: it's validated against the decision it claims to make, and it must build and pass tests. Incoherent or broken work is blocked, not landed.
When AI agents move fast, a half-working change can hit your main line before anyone notices. CatWrangler closes that gap by putting a gate on the write path: nothing merges until it's proven coherent and green.
Three gates on the way in
Reading and exploring stay wide open. The discipline only kicks in when an agent goes to write. Three things happen, in order, before anything touches the shared trunk:
- Describe the change in plain language and get exactly the right files and functions, with the decisions behind them attached — no grepping the whole repo.
- Every agent automatically gets its own line of work to write in. The shared trunk is never written directly.
- On submit, the change is validated: it must actually cover the decision it claims, and it must build and pass tests before it can merge.
Ship it, without a separate pipeline
When a change clears the gate, merge means built, validated, and deployed — no separate CI/CD to wire up. Deploys swap in with no downtime, and a bad one rolls back. A fast path previews changes in seconds. So your trunk stays buildable by construction: the only code that lands is code that already passed.
This works for any language or project type — web, mobile, games, even specs-only repos.
“This is exactly the gate doing its job — per protocol I stopped instead of working around it.”
Related questions
What happens to a change that doesn't build or pass tests?
It's blocked at the gate and never merges. The agent gets an error written for it — what went wrong and the exact next step — so it can rework the change and resubmit without a human stepping in.
Do I have to set up a build or test pipeline for this?
No. Validation and build/test run as part of the merge itself. When a change clears the gate it builds, validates, and deploys on its own — no separate pipeline to maintain.
