Besiege — Git skill for Claude Code

Besiege is a command center for coding agents — terminals, agent sessions, notes, repos, and pull requests, all grouped around the work you're actually doing, with one place to see what needs your attention instead of hunting across terminals and GitHub. It treats every machine you own as one pool of compute: sessions land where there's room, you can attach to any of them from any box, and a machine that's asleep gets woken when there's work for it.

It works with **Claude Code**, **Codex**, **OpenCode** and **Antigravity (`agy`)**, and is built to run on a **[Tailscale](https://tailscale.com) tailnet** — see [Built for Tailscale](#built-for-tailscale).

Besiege doesn't manage the agents — it manages *your* context and attention while the agents manage the code.
