Plan here, build there

You do the thinking on this machine. A separate agent — Claude Code or Codex, installed on a Hetzner VM — does the building. Each slice of the plan gets its own VM, its own branch and its own PR. The job runs under systemd on the VM, so it keeps going after the SSH session ends and after the laptop closes.

Do not use this to drive a remote machine step by step. The handoff is one-shot: the remote agent gets a written brief and the repo, and nothing else.

Procedure

1. Plan on this machine

Explore the codebase here, where it is cheap, and write the plan to a file. This is the normal planning work — read the code, find the real seams, decide the approach.

2. Slice the plan
