Trust & safety
How do you keep AI from deleting or overwriting work?
Your agents never write to the shared trunk directly — each gets its own line of work. Overlap is caught at intent and again at merge, where compatible edits are combined and the rest is routed back for rework, so nothing is ever silently overwritten.
The fear with multiple AI agents on one codebase is that one will quietly stomp another's work. CatWrangler is built so that can't happen: overwriting is structurally off the table, and conflicts are surfaced and resolved instead of swallowed.
Why work can't be silently overwritten
Every agent automatically gets its own line of work the moment it starts. The shared trunk is never written directly, so two agents are never typing over the same place at once. When changes come together, an AI reads the actual code and combines the ones that are compatible.
When it can't safely combine something, it doesn't guess and it doesn't pick a winner. It hands that piece back to the responsible agent to rework, and blocks the merge until it's clean.
- Work is never silently overwritten — incompatible changes are routed back for rework, not discarded.
- Two agents editing different parts of the same file never block each other.
- Conflicts are caught twice: at intent time before any code exists, and again at merge time on the real code.
- Conflicts on shared resources — environment variables, endpoints, tables — are caught too, not just edits to the same lines.
- Stale submissions are blocked, so no one overwrites work that happened while they were away.
“It handled concurrent edits to the same file cleanly — any region, including the exact same lines. CatWrangler is built for parallel agents on the same file.”

What happens if two agents change the same file at the same time?
Edits to different parts of the file are combined automatically and neither agent blocks the other. If two changes truly can't coexist, the merge pauses and the responsible agent is asked to rework its piece before anything lands.
Can an agent overwrite work done while it was offline?
No. Stale submissions are blocked, so an agent that's been away can't merge over progress made in the meantime — it picks up the current state and reworks if needed.
