Configuring LinearB AI & Automations

LinearB provides a set of built-in AI automations that help streamline your PR workflow.

Admins can configure these automations in Settings > Company Settings > AI Tools > AI Tools.

The LinearB AI & Automations tab allows admins to:

Select the operation mode (Managed or Self-Managed).
View and control the status of the LinearB AI Runner.
Enable or disable a catalog of automations that improve review quality and speed.
Customize AI-powered PR descriptions and reviews with organization-specific guidelines.

Choose how automations are executed:

Managed Mode – Automations are executed on the LinearB AI Runner as a managed service. Repository-based automations do not run in this mode.
Self-Managed Mode – Automations are defined in repository configuration files and run on your Git provider’s infrastructure. This mode requires correct setup in the Git provider (see How to Setup gitStream with GitHub).

Switching between modes may affect existing CI workflows. Ensure your repos are configured properly before toggling.

In Managed Mode, admins can enable the following automations across all GitHub repositories selected under Git > Integrations and Repositories:

AI Review – Uses LinearB’s AI service to review PR changes. This can be customized to follow your organization’s guidelines (see Code Review using LinearB's AI).
AI Description – Automatically generates and appends PR descriptions. Guidelines can be tailored for language, style, or formatting (see PR Description Using LinearB's AI).

Label Agents Co-authors – Labels agents (e.g., AI assistants) as co-authors (see Integrate gitStream with Claude Code).
Estimated Time to Review – Adds a label estimating how long a PR will take to review, with color-coded severity (green/yellow/red). See Provide Estimated Time to Review.

Approve Dependabot Minor Bumps – Automatically approves minor version bumps (see Approve and Merge Dependabot Changes).
Approve Dependabot Patch Bumps – Automatically approves patch version bumps (see Approve and Merge Dependabot Changes).

For AI Review and AI Description, you can edit default behavior:

Click Edit next to the automation.
Add organization-specific guidelines (e.g., “Write PR descriptions in Spanish” or “Do not comment on formatting issues”).
Test the guidelines in the Playground with a reference PR.
Refine your rules until you get the expected output.
Save your guidelines to apply them across all repositories.

This enables you to enforce consistent code review standards and tailor PR descriptions to your team’s style and needs.

The LinearB AI & Automations tab lets admins enable and manage LinearB’s catalog of AI-powered automations. Use this tab to select an operation mode, turn automations on or off, and customize AI Review and AI Description to match your organization’s standards.
