description: Deploy or operate OpenTag's supported paired setup when a user needs to bootstrap the self-hosted Docker Compose Control Plane and Slack Source App, configure or pair a local ACP Runner with a GitHub Project Target, start the Runner service, verify readiness, or diagnose a Slack mention that did not complete.

OpenTag

Supported route

Slack Source App
  -> self-hosted Control Plane
  -> paired local Runner
  -> ACP Agent in one local checkout
  -> GitHub Project Target/publication
  -> truthful result in the originating Slack thread

Slack is the only Source App. GitHub is the Project Target and publication/evidence provider. The Control Plane owns Slack ingress, custody, and projection; the Runner owns local execution.

Load the needed reference

• Compose deployment, Slack bootstrap, TLS, or pairing authority:

`references/control-plane.md`

• Slack app URLs, events, scopes, channel binding, or missing mentions:

`references/slack-setup.md`

• GitHub target, local checkout, publication, or readback:

`references/github-setup.md`

• Codex or another supported ACP executor:

`references/codex-runner.md`

• Any failed readiness, pairing, Run, or delivery step:

`references/troubleshooting.md`

Load only the references whose branch applies.

Guardrails

• Pair only with the exact HTTPS Control Plane origin the user operates or

explicitly trusts.

• Keep Slack signing and bot secrets in Control Plane secret files. Its `.env`

contains only their host-side file paths and non-secret Slack identifiers.

• Enter the bootstrap pairing authority and GitHub token through local secret

input. Keep them out of chat, command arguments, logs, screenshots, and git.

• The ACP Agent edits only the assigned local checkout. OpenTag performs Slack

delivery and GitHub publication through governed provider boundaries.

• Preserve unrelated working-tree changes. Confirm the checkout and target

before enabling write-capable work.

• Run completion, enqueue, approval, and provider acceptance are separate

facts. Preserve `outcome_unknown` until the original provider operation is reconciled.

Paired workflow

1. Bootstrap the Control Plane and Slack installation from `deploy/compose/.env.example`, using file-backed Slack secrets, then start Compose behind TLS. Completion: the Compose project reports healthy, `/readyz` succeeds, and bootstrap logs show the intended Slack binding without secret plaintext.

2. Install the reviewed CLI and verify the local checkout and ACP login.

   npm install -g @opentag/cli@0.11.0
   opentag --version
   git -C /absolute/path/to/checkout status --short

Completion: the CLI reports `0.11.0`, the user has accepted the checkout state, and the chosen ACP executor is locally authenticated.

3. Configure the Runner, trusted relay, checkout, ACP executor, and GitHub Project Target. Omit secret flags so the CLI prompts locally.

   opentag setup \
     --relay https://control.example.com \
     --project /absolute/path/to/checkout \
     --executor codex \
     --github-repository owner/repo \
     --project-target-id target_team

Replace `target_team` with the active Slack binding's Project Target ID from Compose. Do not require a duplicate Runner environment variable for it.

Setup performs the initial pair. For an existing configuration that is still unpaired, complete that same pairing with:

   opentag pair \
     --relay https://control.example.com \
     --trust-relay-origin https://control.example.com

Completion: redacted config shows `paired_relay`, the exact trusted origin, a paired Runner registration, and the intended GitHub target ID; pairing has registered that target through the active Slack binding and verified exact Control Plane readback. The bootstrap token is not retained in Runner config.

4. Keep the Runner active in one supported mode.

   opentag start
   # or, after a global install:
   opentag service install
   opentag service start
   opentag service status

Completion: the service reports running and ready, the runtime credential is accepted by the Runner Control Context endpoint, and the configured ACP executor is ready.

5. Verify before inviting work.

   opentag doctor
   opentag status
   opentag config show

Completion: required checks pass, the relay and Runner identities match, the checkout maps to the intended GitHub target, and displayed secrets are redacted.

6. Mention the installed OpenTag app in the bootstrapped Slack channel with one bounded task. Completion: the signed Slack event creates one WorkThread and Run, the paired Runner claims one fenced Attempt, and the originating thread receives a concise result or an explicit actionable failure.

The setup is complete only when every completion criterion above holds on the paired route. A local process exit, queued delivery, generated pull-request URL, or Slack acknowledgement alone is insufficient.
