What is multi-agent (agentic) software development?
Multi-agent software development is many people and AI coding agents building one codebase at the same time. Each agent gets its own isolated line of work; conflicts are surfaced and negotiated before any code exists, then resolved again at merge — so nothing lands broken or silently overwritten.
As soon as more than one agent touches a codebase, the hard part stops being writing code and becomes coordination: keeping work isolated, catching collisions early, and merging without clobbering anyone. CatWrangler is built for exactly that.
What it actually involves
The category covers humans and AI agents writing into the same repository concurrently. At AI speed, that means collisions are constant, not an edge case — two agents will reach for the same file, the same endpoint, the same table within minutes of each other.
- Per-agent isolation: every agent (and every sub-agent it spawns) gets its own identity and its own line of work the instant it starts. The shared trunk is never written directly.
- Conflicts resolved before they happen: at intent time, before any code exists, incompatible choices between two agents are surfaced and negotiated.
- Conflicts resolved again at merge: an AI reads the actual code, combines the compatible changes, and — when it can't safely resolve one — sends it back to the responsible agent and blocks the merge until it's clean.
- Disjoint work never blocks: two agents editing different parts of the same file don't wait on each other. Collisions on shared resources like env vars, endpoints, and tables are caught too, not just the same lines.
Where CatWrangler fits
CatWrangler is an AI-mediated decision tracking and source-control system — version control rebuilt for teams of humans and AI agents who build the same codebase at the same time. An AI sits in the middle of every read, write, and merge, so work is never silently overwritten and the reasoning behind every change stays attached to the code. It runs server-side; you point your agents at it and build, without ever touching Git, a branch, or a merge.
“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.”
Related questions
Do agents step on each other's work?
No. Each agent gets its own isolated line of work, and the shared trunk is never written directly. Conflicts are negotiated at intent time and resolved again at merge; work is never silently overwritten, and stale submissions are blocked.
What happens when two agents edit the same file?
If they touch different parts, they never block each other. Where the changes actually collide, an AI combines what's compatible and sends the rest back to the responsible agent to rework — the merge stays blocked until it's clean.
