I'm building "workboxes" to work on my startup. It helps me develop features insanely fast. A workbox is a simple worktree-in-a-sandbox per feature. I have a simple front end where I can launch new workboxes: I input a prompt (a documented grilling session) and it creates a branch, a PR, and starts an opencode coding session on an e2b sandbox based on a custom template with the app's monorepo. Each workbox has a public https endpoint so I can manually test the web app after the coding session is complete. At any point I can either approve the PR, send a follow-up prompt, or connect to the opencode session for more control.

I think my next step is to perform the grilling session inside the front end, currently I perform it in my terminal and then paste in the front end.
