# Sandboxer — Dispatch Tasks to Tmux Sessions

> **Power-user skill.** Sandboxer gives agents full access to tmux sessions, workspace files, and terminal output on your server. Intended for dedicated AI machines where agents run with root access. Not for shared or untrusted environments.

Sandboxer runs on `localhost:8081`. No auth needed from localhost.

Quick: Dispatch a Task

# 1. Spawn a Claude session in a repo
curl "localhost:8081/api/create?type=claude&dir=/root/workspaces/AGENT/data/repos/PROJECT"

# 2. Send it a task
curl "localhost:8081/api/send?session=SESSION_NAME&text=Fix+the+failing+tests"

# 3. Check progress
curl "localhost:8081/api/session-monitor?session=SESSION_NAME"

# 4. Kill when done
curl "localhost:8081/api/kill?session=SESSION_NAME"

Session types: `claude`, `bash`, `lazygit`, `gemini`, `opencode`

Workspace Structure

Sandboxer manages `/root/workspaces/` — a single git repo containing all agent workspaces.

/root/workspaces/                          ← git repo (Sandboxer commits this)
├── .gitignore                             ← tracks only .md, .gitignore, cronjobs/
├── <agent-name>/                          ← one folder per OpenClaw agent
│   ├── AGENTS.md                          ← agent behavior rules
