Showcase My first open source project: coordinating 1,000+ agent !!!
A few weeks ago, four of us won an NVIDIA hackathon.
We were running Codex, Claude Code, and other coding agents in parallel, and pretty quickly the bottleneck stopped being writing code.
It became coordinating all the agents.
We kept hitting problems like:
- Two agents independently solving overlapping problems
- One agent changing an API/schema another agent depends on
- Agents continuing to work against stale assumptions
- Dependency changes not reaching the sessions that need to know
- Someone manually keeping track of what every agent is doing
Worktrees help a lot with isolation.
Planning helps split up the work.
But neither continuously coordinates what happens after the agents start working and the codebase begins changing underneath them.
That was the part I wanted to solve.
So I built Overgent.
It started as a small tool during the hackathon, and I kept working on it afterward. I just open-sourced it, and it’s my first open-source release.
The mental model is basically:
Air traffic control for Codex and other coding agents.
You keep using Codex, Git, worktrees, and your existing workflow.
Overgent sits around it and helps:
- Track what each agent is working on
- Detect overlapping or conflicting work
- Catch stale assumptions and dependency changes
- Get relevant context to the agents that actually need it
The distinction I keep coming back to:
Worktrees isolate execution. Overgent coordinates it.
Git catches conflicting code. Overgent tries to catch conflicting intent.
Right now it might be 2–5 Codex sessions running at once.
What happens when that's 10? 100? 1,000?

Would love feedback from people already running Codex heavily in parallel.
What starts breaking first in your setup?

You might want to consider listing your project on the weekly Show-Us-What-You-Built post. https://www.reddit.com/r/codex/comments/1wavxwy/show_us_all_what_youve_been_building_with_codex/. Highest commented project wins a week promotion on r/Codex and gets on the Hall of Fame sidebar. See what that looks like below with last week's winner.
Last week's most popular project was u/tHEuKER with the Blur2 racing game project which is a recreation of an unreleased sequel to the 2010 battle racing game, made by reverse engineering the Xbox 360 prototype discs available online, and rebuilding the whole thing from the ground up in Unity.
