title: Reaction recipes
description: Practical reaction configurations — watch-only mode, auto-merge, custom CI messages, and bot handling.

Reactions are configured under `reactions:` (global) or `projects.*.reactions:` (per-project). Every recipe here uses the correct schema field names; see the [Reactions reference](/docs/configuration/reactions) for the full list of keys and their defaults.

## Recipe: Watch-only mode

Disable all automated agent messages while keeping notifications active. Useful during onboarding or in sensitive projects where you want to observe before letting AO act:

```yaml
reactions:
  ci-failed:
    auto: false
  changes-requested:
    auto: false
  bugbot-comments:
    auto: false
  agent-idle:
    auto: false
```

`auto: false` suppresses the `send-to-agent` action but does not silence notifiers. Reactions whose default action is `notify` (like `agent-stuck`, `agent-exited`, and `all-complete`) continue to fire their notifications regardless of this flag.

## Recipe: Enable auto-merge

`approved-and-green` defaults to `auto: false` (notify-only). Opt in explicitly:

```yaml
reactions:
  approved-and-green:
    auto: true
    action: auto-merge
```

<Callout type="warning">
	The `auto-merge` action currently calls `notifyHuman()` internally — it does not perform a real merge. Actual merging
	still depends on your repository's branch protection rules and the "Allow auto-merge" setting on GitHub. AO does not
	bypass these gates. Treat `auto-merge` as an opt-in signal for when the SCM plugin adds real merge support.
</Callout>

## Recipe: Custom CI failure message

Override the default `message` to give the agent more precise recovery instructions:

```yaml
reactions:
  ci-failed:
    message: |
      CI is failing. Run `pnpm test` locally and fix the failing tests before pushing again. Prioritise type errors first.
```

The two-pass CI behavior still applies: AO sends your custom `message` on the first pass (transition), then follows up in the next poll cycle with a second message listing every failing check by name and URL. Your `message` override affects only the first pass — the structured check list fires regardless.

## Recipe: Aggressive escalation

Tighten the retry and escalation windows for urgent projects where you want fast human handoff:

```yaml
reactions:
  ci-failed:
    retries: 1
    escalateAfter: "5m"
  changes-requested:
    retries: 1
    escalateAfter: "5m"
```

With `retries: 1` and `escalateAfter: "5m"`, AO will escalate after one failed recovery attempt or five minutes — whichever comes first.

## Recipe: Ignore bugbot noise

Keep human `changes-requested` reactions fully active but silence automated bot review nudges:

```yaml
reactions:
  bugbot-comments:
    auto: false
```

AO identifies bot comments by author login. The current hardcoded bot list in `scm-github` includes `cursor[bot]`, `github-actions[bot]`, `codecov[bot]`, and `sonarcloud[bot]`. Any review comment from these accounts triggers `bugbot-comments` rather than `changes-requested`. Setting `auto: false` here stops AO from nudging the agent about bot feedback while leaving human review comments fully active.

## Recipe: Per-project overrides

Suppress a noisy notification for one project while leaving everything default for others:

```yaml
reactions:
  all-complete:
    auto: true
    action: notify

projects:
  myapp:
    repo: org/myapp
    path: ~/code/myapp
    reactions:
      all-complete:
        auto: false # suppress the "all sessions done" notification for this project

  otherproj:
    repo: org/otherproj
    path: ~/code/otherproj
    # inherits global defaults — all-complete notification fires as normal
```

Per-project reaction blocks are merged with the global config; the project value wins for every field that is specified.

## Recipe: Stuck session threshold

Extend the `agent-stuck` threshold for projects with long-running builds where `10m` of inactivity is normal:

```yaml
reactions:
  agent-stuck:
    threshold: "30m"
```

The `threshold` field is used exclusively by `agent-stuck`. A session must be continuously idle for longer than `threshold` before the reaction fires and the session status transitions to `stuck`.
