| 1 | +# Managed Mode |
| 2 | + |
| 3 | +!!! tip "Setup Configuration" |
| 4 | + Managed Mode setup is configured entirely from the LinearB platform. You do not need to setup gitStream yourself, add any GitHub Actions, or create CM rule files - all of this is handled automatically by the LinearB platform. For detailed setup instructions, see [Managing AI Services in LinearB](https://linearb.helpdocs.io/article/hvm9neua4e-managing-ai-services-in-linear-b#ai_tools_automations). |
| 5 | + |
| 6 | +Managed Mode is an operation mode for LinearB AI automations where automations run on the LinearB runner as a managed service. This mode is required for accessing AI Insights and provides centralized control of AI automations through LinearB's infrastructure. |
| 7 | + |
| 8 | +## Available Managed Automations |
| 9 | + |
| 10 | +### AI Code Review |
| 11 | + |
| 12 | +Use LinearB's AI with the `code-review` action to automatically review the introduced changes to the code. This automation triggers on non-draft PRs that were not created by bots and can be customized with specific review guidelines. |
| 13 | + |
| 14 | +```yaml |
| 15 | +automations: |
| 16 | + linearb_ai_review: |
| 17 | + if: |
| 18 | + - {{ not (pr.draft or is.bot_author) }} |
| 19 | + run: |
| 20 | + - action: code-review@v1 |
| 21 | + args: |
| 22 | + guidelines: {{ loadReviewGuidelines() | dump }} |
| 23 | +``` |
| 24 | +
|
| 25 | +### AI PR Description |
| 26 | +
|
| 27 | +Use the `describe-changes` automation action to automatically generate and append a concise, AI-generated description to a pull request. This helps provide clear context for reviewers about the changes introduced. |
| 28 | + |
| 29 | +```yaml |
| 30 | +automations: |
| 31 | + linearb_ai_description: |
| 32 | + if: |
| 33 | + - {{ not (pr.draft or is.bot_author) }} |
| 34 | + run: |
| 35 | + - action: describe-changes@v1 |
| 36 | + args: |
| 37 | + concat_mode: append |
| 38 | + guidelines: {{ loadDescriptionGuidelines() | dump }} |
| 39 | +``` |
| 40 | + |
| 41 | +### Smart Labeling (Claude Code Detection) |
| 42 | + |
| 43 | +Automatically apply labels to PRs that are assisted by Claude Code to track time savings, PR risk, and productivity lift from AI tools. This automation can detect Claude Code usage through multiple methods including co-authorship, user prompts, known users, or specific tags. |
| 44 | + |
| 45 | +```yaml |
| 46 | +automations: |
| 47 | + tag_claude_in_pr: |
| 48 | + if: |
| 49 | + - {{ is.claude_author or is.claude_co_author }} |
| 50 | + run: |
| 51 | + - action: add-label@v1 |
| 52 | + args: |
| 53 | + label: 🤖 Claude Code |
| 54 | +
|

| 91 | +### Estimated Time to Review |
| 92 | + |
| 93 | +Label all PRs with an estimated number of minutes it would take someone to review. gitStream automatically updates this label whenever a PR changes, providing valuable insight for reviewers and team planning. |
| 94 | + |
| 95 | +```yaml |
| 96 | +automations: |
| 97 | + estimated_time_to_review: |
| 98 | + if: |
| 99 | + - true |
| 100 | + run: |
| 101 | + - action: add-label@v1 |
| 102 | + args: |
| 103 | + label: "{{ calc.etr }} min review" |
| 104 | + color: {{ colors.red if (calc.etr >= 20) else ( colors.yellow if (calc.etr >= 5) else colors.green ) }} |

| 113 | +``` |
| 114 | + |
| 115 | +### Dependabot Auto-merge |
| 116 | + |
| 117 | +Auto-merge Dependabot PRs for patch and minor version updates. This automation helps maintain dependencies while ensuring only safe, non-breaking changes are automatically approved and merged. |
| 118 | + |
| 119 | +```yaml |
