Firstmate agent crew
How I run several coding agents at once without juggling tabs. I talk to one agent, Firstmate (Kun Chen's open-source project), and it dispatches a crew: cheaper models research, a writing model drafts, Claude Code builds and Codex reviews. Every change passes an automatic review pipeline before it's pushed.
- Why
- My ambitions outran my attention. With three or four jobs running in parallel I kept losing track of which terminal had the failing test. Now I give direction and Firstmate keeps the crew on task.
How I built it
- I installed Firstmate and no-mistakes from GitHub.
- I wrote a dispatch file that says which model does which kind of job, with my reason next to each rule.
- For example: research for writing goes to a cheaper model than the drafter, and all review goes to Codex on high effort.
- Every agent must address me as 'captain' in chat, never in commits or files.
- Changes go through the no-mistakes pipeline: review, tests and checks, before they reach GitHub.
- To copy it you need
- Firstmate and no-mistakes (both free on GitHub), Claude Code, or the AI of your choice, plus any second AI for review. Gotcha: write the reason next to every routing rule, so you remember why a job got the expensive model.
Try it yourself
Copy this prompt and paste it into ChatGPT or Claude to try it yourself.
I want to run several AI coding agents at once without juggling windows. Korab Eland does this with Firstmate (github.com/kunchenguid/firstmate), as shown on whatarewebuilding.ai: Korab talks to one agent, Firstmate, which hands work to a crew, with a dispatch file saying which model does which job and why. Research goes to a cheaper model, building to Claude Code, and all review to a different AI. Help me set up a starter version. First ask which AI tools and subscriptions I have. Then write a short dispatch file with a reason for each rule. Ask me for anything you need.
