pairtask

# pairtask **Codex and Claude, working together in a sandbox.** pairtask pairs a Claude and a Codex agent as a duo that shares tasks, messages and a workspace. - Real-time collaboration with durable messages and automatic delivery. - An isolated Incus workspace with persistent projects and agent memory. - Token usage visibility and soft caps for managed Codex; shared caps are not yet available.

Provisioning runs OpenTofu in a disposable container; no host Terraform/OpenTofu install is needed. Dev has network access; optional control stays offline. Host credentials and conversations are not imported. **Host prerequisites:** Python, Git, OpenSSH and Incus; macOS also needs Colima. [Install commands](docs/sandbox.md#1-install-the-host-tools). No `gh` or browser download needed. ```sh # First install or upgrade (Incus must be running; upgrades end active sessions) python3 scripts/sandbox-provision.py rollout # Pin a version: add --release workspace-vX.Y.Z ``` Run host commands from your provisioning checkout. On Linux, skip Colima commands and use `local:` / `--remote local`. For host mounts, see the [`mounts.json` example](docs/sandbox-mounts.md#choose-directories). ```sh # HOST: run from your provisioning checkout # Start the Mac VM, then the containers python3 scripts/sandbox-host.py apply incus --project collab-ai start colima-collab-ai:secured # if secured_runtime = true incus --project collab-ai start colima-collab-ai:workspace # Check: expect workspace (and secured, if enabled) to show RUNNING incus --project collab-ai list colima-collab-ai: # Optional: preview host mounts; uncomment with your file (does not apply) # python3 scripts/sandbox-host.py mounts-plan --mounts-file /path/to/mounts.json # Configure SSH once, check the broker, then enter dev python3 scripts/sandbox-ssh.py --remote colima-collab-ai ssh -F infra/incus/ssh/config workspace pairtask status ssh -F infra/incus/ssh/config workspace # CONTAINER: all commands below until exit run inside your SSH session # First use only: uncomment to sign in before starting agents # Codex: open the printed URL on your host and enter the device code # command codex login --device-auth # command claude auth login # gh auth login --web --git-protocol https # optional GitHub CLI login # pairtask-codescene-login # optional CodeScene token; hidden prompt # First use only: clone if you have not already done so # git clone https://github.com/pairtask/pairtask.git /workspace/collab-ai tmux new -A -s collab # In each tmux window: enter the project, then choose one agent or dashboard # Ctrl+B then C opens another window cd /workspace/collab-ai codex # new managed Codex conversation # codex resume # choose a saved sandbox conversation # codex resume SESSION_ID # resume a specific sandbox conversation # claude # Claude with collaboration channels enabled # claude --resume # resume Claude # dashboard # broker status and agent inboxes # rtk gain # estimated shell-output token savings # docker info # rootless Docker inside workspace # docker compose up -d # run your project's compose.yaml # Disconnect: Ctrl+B then D detaches tmux; exit leaves SSH exit # HOST AGAIN: optional shutdown; stops agents, keeps persistent files # incus --project collab-ai stop colima-collab-ai:workspace # incus --project collab-ai stop colima-collab-ai:secured # if secured_runtime = true # colima stop collab-ai ``` Expect `Broker: ready`. Run one Codex and one Claude session; additional sessions need distinct agent IDs. [Login help](docs/sandbox.md#sign-in-and-network-access). Both agents should read `/usr/local/share/pairtask/SKILL.md`. [Mount directories](docs/sandbox-mounts.md) · [Mac writable sharing](docs/sandbox-mounts.md#mac-writable-sharing) · [Docker and Compose](docs/sandbox.md#docker-and-compose) · [Bundled MCP tools](docs/sandbox.md#bundled-mcp-tools) · [Upgrade or reprovision](docs/sandbox-storage.md#replace-dev-retain-data) · [Back up](docs/sandbox-storage.md#back-up-and-restore) · [Stop or remove](docs/sandbox.md#stop-or-remove) ## Dashboards Run on your host: ```sh # Agent connections and pending messages (terminal UI) ssh -t -F infra/incus/ssh/config workspace pairtask dashboard # Containers, resources and logs (browser UI) incus webui colima-collab-ai: # Linux: incus webui local: ``` For Incus, open the printed URL and select project `collab-ai`. The collaboration dashboard is read-only; prompts and approvals stay in agent terminals. [Controls](docs/dashboard.md) · [UI help](docs/sandbox.md#incus-web-ui). ## How it fits together With `secured_runtime = true`, Codex, Claude and the read-only dashboard run in **workspace**; **secured** owns one broker and SQLite database. The shared Unix socket connects them. `/workspace` and `/home/agent` persist across container replacement.  [Architecture source](docs/assets/architecture.puml) · [Control setup](docs/secured-runtime.md) <details> <summary>macOS and Linux layouts</summary> | macOS: Colima hosts Incus | Linux: Incus runs directly | | --- | --- | |  |  | | [Diagram source](docs/assets/sandbox-macos.puml) | [Diagram source](docs/assets/sandbox-linux.puml) | </details> ## Security Agent commands run inside the container. Host mounts default to read-only; writes require a dedicated sharing identity. Writable sharing lets agents change files that you or host automation may later execute. [Boundaries](docs/sandbox.md#security-can-agents-execute-code-on-my-host). ## Run on your host No Incus? Follow the [host quick start](docs/quickstart.md) to build and run locally. These agents have no Incus isolation. ### Resume or fork [Host commands and compatibility](docs/host-integration.md#codex-terminal). Sandbox start/resume commands are in the daily block above. ### Set a Codex soft cap The sandbox aliases are uncapped by default. Use a [named budget](docs/host-integration.md#codex-soft-cap) for one managed Codex launcher. Reports can arrive late; overshoot is possible. Claude and shared budgets are not yet covered. ### Claude Code The sandbox alias is preconfigured. For host sessions, use the [dedicated channel config](docs/quickstart.md#3-start-claude-code). Claude requires channel consent and account/organization support. ## Reference and contributing [Protocol](docs/protocol.md) · [Manual MCP](docs/mcp.md) · [Status API](docs/status.md) · [Agent skill](docs/skills/collab-ai/SKILL.md) [Report an issue](https://github.com/pairtask/pairtask/issues).
