README

Polter

Put one Claude Code session in charge of the others.
It reads the text on their screens, types into them, opens new tabs, and minds them while you're asleep.
Polter itself has no account and no API key, and makes no network calls of its own.

What it does

Several Claude Code and Codex windows at once are hard to coordinate, sub-agents stop partway through a long run, and an overnight job tends to knock off after two hours. Polter lets you mark one tab as the **supervisor**. It's an ordinary Claude Code session, with these added:

Read the text on any tab's screen (text, not screenshots)
Type into any tab
Open new tabs and start agents in them
Make a group chat, hand out tasks, take reports; the panel survives a restart
Get told how long any tab has been still

A worker is not a sub-agent. It's an independent session in its own terminal, and what it did lands on disk line by line — you can `grep` it in the morning.
