The build system behind my work
The best fully autonomous agent, remote controlled from your phone.
I built Mantis because I needed a workflow that could keep up with how fast I build. I needed something much better than what the big AI labs were giving me.
This is the build system I used to build every real-world product below.
Mantis itself is in private beta. Install details are below.
Your workflow—not theirs
Build the workflow. Chain the specialists.
Codex coordinates the job. A skill can bring in Claude for the front end or Gemini for customer-facing copy, then keep the result inside the same live project. You decide the rules.
Run the real terminal, files, browsers, tests, and installed apps. Change the specialist without changing the project.
Proof, not promises
This is the build system I used to build all of this.




The work at a glance
Every session tells you what it is doing.
Mantis names each session from the goal and recent work, then updates the working tail as the job changes.
Workspaces autosave. Restore the layout or resume an older Codex thread when you need it.
The built-in rulebooks
Teach the system how you work.
A skill tells the coordinator how to do the job, when to call a specialist, and what proof must pass before the work is finished.
