CodeRabbit Configuration: Complete .coderabbit.yaml Reference (2026)

Why CodeRabbit configuration matters

Every engineering team has different coding standards, project structures, and review priorities. Running CodeRabbit with its default settings works well enough for getting started, but the real value comes from tailoring the AI reviewer to understand your specific codebase. The .coderabbit.yaml configuration file is how you make that happen.

Without configuration, CodeRabbit reviews every file with the same level of scrutiny, applies generic review criteria, and has no understanding of which parts of your codebase are security-critical versus which are boilerplate. With a well-tuned configuration, CodeRabbit focuses on what matters most to your team - checking API routes for authentication gaps, database code for injection vulnerabilities, and infrastructure files for misconfigurations - while staying quiet on auto-generated files, lock files, and build artifacts that do not need review.

This reference guide covers every section of the .coderabbit.yaml file in detail, with practical examples for solo developers, small teams, and large organizations. If you have not installed CodeRabbit yet, start with our how to use CodeRabbit guide first. If you want a broader overview of the tool’s capabilities, read our CodeRabbit review.

The .coderabbit.yaml file structure

The .coderabbit.yaml file lives in the root directory of your repository and must be committed to your default branch (typically main or master). CodeRabbit reads this file every time it reviews a pull request and applies your settings automatically.

Here is the complete top-level structure:

# .coderabbit.yaml - complete structure
language: en-US

reviews:
  profile: chill
  request_changes_workflow: false
  high_level_summary: true
  high_level_summary_placeholder: "@coderabbitai summary"
  auto_title_placeholder: "@coderabbitai"
  poem: false
  review_status: true
  collapse_walkthrough: false

    incremental_reviews: true
  tools:

chat:
  auto_reply: true

knowledge_base:
  opt_out: false
  learnings:
    scope: auto

Every field is optional. If you omit a field, CodeRabbit uses its default value. You can start with a minimal configuration and expand it as you learn which settings matter most for your team.

The simplest possible .coderabbit.yaml file that still changes behavior might look like this:

reviews:
  profile: chill
  path_filters:
    - "!**/*.lock"

This sets the review profile to chill and excludes lock files from review. Everything else uses defaults.

Review profiles

The reviews.profile field controls how aggressively CodeRabbit comments on your pull requests. This is the single most impactful configuration option because it determines the overall volume and scope of review feedback.

chill

reviews:
  profile: chill

The chill profile generates fewer comments and focuses on significant issues only. CodeRabbit will flag bugs, security vulnerabilities, logic errors, and potential runtime failures. It stays quiet on style preferences, naming conventions, missing documentation, and minor code quality suggestions.

Best for: Teams that are new to CodeRabbit, teams that already have strong linting and formatting tools in place, or teams where developers find verbose automated feedback disruptive.

assertive

reviews:
  profile: assertive

The assertive profile is more thorough. In addition to bugs and security issues, CodeRabbit comments on code style, naming quality, documentation gaps, test coverage concerns, and adherence to best practices. This profile generates significantly more comments per PR.

Best for: Teams that want comprehensive feedback, teams without extensive linting tooling, or teams doing thorough code quality enforcement.

followup

reviews:
  profile: followup

The followup profile behaves like assertive but adds an additional layer - it tracks whether previous review comments were addressed in subsequent commits. If CodeRabbit flagged an issue on a commit and the next push does not resolve it, CodeRabbit brings it up again.

Best for: Teams that want accountability on review feedback, teams with less experienced developers who benefit from reminders, or teams where review comments frequently go unaddressed.

Most teams should start with chill and move to assertive after two to four weeks once the team is comfortable with CodeRabbit’s feedback patterns. This gradual approach prevents the common failure mode where developers are overwhelmed by automated comments on day one and tune out the tool permanently.

Path filters

The reviews.path_filters field controls which files CodeRabbit includes or excludes from review. This is critical for keeping reviews focused and avoiding noise from files that do not benefit from AI analysis.

Exclusion patterns

Use negation patterns (prefixed with !) to exclude files:

reviews:
  path_filters:
    # Build artifacts and generated files
    - "!**/dist/**"
    - "!**/build/**"
    - "!**/out/**"
    - "!**/.next/**"

    # Dependencies
    - "!**/node_modules/**"
    - "!**/vendor/**"

    # Lock files
    - "!**/*.lock"
    - "!**/package-lock.json"
    - "!**/yarn.lock"
    - "!**/pnpm-lock.yaml"
    - "!**/Gemfile.lock"
    - "!**/composer.lock"

    # Generated code
    - "!**/*.generated.*"
    - "!**/*.gen.*"
    - "!**/generated/**"
    - "!**/__generated__/**"

    # Minified files
    - "!**/*.min.js"
    - "!**/*.min.css"

    # Test artifacts
    - "!**/coverage/**"
    - "!**/__snapshots__/**"

    # Assets
    - "!**/*.png"
    - "!**/*.jpg"
    - "!**/*.svg"
    - "!**/*.ico"
    - "!**/*.woff"
    - "!**/*.woff2"

Inclusion patterns

You can also use inclusion patterns (without the ! prefix) to limit CodeRabbit’s scope to specific directories:

reviews:
  path_filters:
    - "src/**"
    - "lib/**"
    - "tests/**"

When inclusion patterns are present, CodeRabbit only reviews files matching those patterns and ignores everything else. This is useful for monorepos where you want CodeRabbit focused on specific services.

Combining inclusion and exclusion

You can mix both types:

reviews:
  path_filters:
    - "src/**"
    - "lib/**"
    - "!**/*.generated.*"
    - "!**/*.lock"

This tells CodeRabbit to review files under src/ and lib/ but still exclude generated files and lock files within those directories.

Path-specific instructions

The reviews.path_instructions field is the most powerful configuration feature in CodeRabbit. It lets you attach natural language review guidance to specific directories or file patterns. When a PR changes files matching a pattern, CodeRabbit reads the associated instructions and adjusts its analysis focus.

Basic structure

reviews:
  path_instructions:
    - path: "src/api/**"
      instructions: |
        Review all API endpoints for:
        - Input validation on all request parameters
        - Proper error handling with appropriate HTTP status codes
        - Authentication and authorization checks on every route
        - Rate limiting considerations for public endpoints
    - path: "src/db/**"
      instructions: |
        Review database code for:
        - SQL injection prevention using parameterized queries only
        - Proper connection handling and cleanup
        - Transaction usage where multiple writes occur
        - Index usage for frequently queried fields

Instructions for different file types

You can target instructions by file extension as well as directory:

reviews:
  path_instructions:
    - path: "**/*.test.*"
      instructions: |
        For test files, check:
        - Edge case coverage including null, undefined, empty, and boundary values
        - Proper assertion usage with specific expected values
        - Mock cleanup and isolation between tests
        - No hardcoded timeouts or sleep calls
    - path: "**/*.tsx"
      instructions: |
        For React components, check:
        - Proper cleanup in useEffect hooks
        - Memoization of expensive computations and callbacks
        - Accessible markup with proper ARIA attributes
        - Error boundary usage for async operations
    - path: "**/Dockerfile*"
      instructions: |
        For Dockerfiles, check:
        - Multi-stage builds to minimize image size
        - Non-root user for running the application
        - Pinned base image versions
        - Proper layer ordering for cache efficiency

Monorepo instructions

For monorepos, path instructions let you apply entirely different review criteria to each service:

reviews:
  path_instructions:
    - path: "services/auth/**"
      instructions: |
        This is the authentication service. Focus on:
        - Token validation and expiration handling
        - Password hashing using bcrypt, not MD5 or SHA
        - OWASP authentication best practices
        - Session management and cookie security
    - path: "services/payments/**"
      instructions: |
        This is the payment processing service. Focus on:
        - PCI DSS compliance patterns
        - Idempotency of payment operations
        - Decimal precision for currency calculations (never use float)
        - Audit logging for all payment state changes
    - path: "services/notifications/**"
      instructions: |
        This is the notification service. Focus on:
        - Rate limiting for email and SMS sends
        - Template injection prevention
        - Proper retry logic with exponential backoff
        - Dead letter queue handling for failed deliveries

Global review instructions

The reviews.instructions field provides natural language guidance that applies to every file in every PR. Use this to define project-wide conventions and set the overall tone of reviews.

reviews:
  instructions: |
    This is a TypeScript backend service using Express and PostgreSQL.
    We follow these conventions:
    - All async functions must use try-catch with structured error logging
    - Database queries must use parameterized statements, never string concatenation
    - API responses follow our standard envelope format: { data, error, meta }
    - Environment variables must be validated at startup, not at usage time
    - Do not comment on import ordering (handled by ESLint)
    - Do not comment on line length (handled by Prettier)
    - Do not comment on missing JSDoc unless the function is exported
    Focus on bugs, security issues, and logic errors over style preferences.

The key benefit of global instructions is telling CodeRabbit what not to comment on. If your team already has Prettier for formatting and ESLint for style enforcement, there is no value in CodeRabbit duplicating those checks. Explicit exclusions in the global instructions prevent this overlap and dramatically reduce noise.

Language settings

The top-level language field controls the language CodeRabbit uses for all of its output - review comments, PR summaries, walkthrough descriptions, and chat responses.

language: en-US

Supported language codes include en-US, es, fr, de, ja, zh, ko, pt-BR, it, nl, ru, ar, hi, and over 20 others. This is particularly valuable for internationally distributed teams where not all developers are comfortable reading English review feedback.

# Japanese review comments for a team in Tokyo
language: ja

The language setting applies globally to all CodeRabbit output for the repository. There is no way to set different languages for different file paths or different reviewers within a single repository.

Chat commands

CodeRabbit supports interactive commands through PR comments. While these are not configured in .coderabbit.yaml, understanding them is essential for getting full value from your CodeRabbit configuration.

Available commands

Command	Effect
@coderabbitai review	Triggers a full re-review of the PR, re-reading the config file
@coderabbitai resolve	Dismisses a specific review thread
@coderabbitai explain	Provides a detailed explanation of the flagged issue
@coderabbitai generate docstring	Generates documentation for the function in context
@coderabbitai configuration	Displays the active configuration and any parsing errors
@coderabbitai help	Lists all available commands

Chat auto-reply

The chat.auto_reply field controls whether CodeRabbit automatically responds when developers reply to its review comments:

chat:
  auto_reply: true

When set to true (the default), CodeRabbit responds conversationally to any reply on its review comments. When set to false, CodeRabbit only responds when explicitly mentioned with @coderabbitai.

For teams that want CodeRabbit to be fully interactive, keep this at true. For teams that find the back-and-forth distracting, set it to false and use the explicit mention syntax when you want a response.

Using commands with configuration

The @coderabbitai configuration command is especially useful when debugging your .coderabbit.yaml. If your configuration changes are not taking effect, post this command on any PR to see what CodeRabbit is actually reading. The output shows the parsed configuration including any syntax errors, default values being used, and the effective settings after merging your file with the defaults.

The @coderabbitai review command forces CodeRabbit to re-read the configuration file, which is helpful when you have just committed a .coderabbit.yaml change and want to see its effect immediately without opening a new PR.

Linter configuration

CodeRabbit Pro includes 40+ built-in linters that run alongside the AI review engine. These linters provide deterministic, rule-based analysis that complements the AI’s contextual review.

Enabling and disabling linters

reviews:
  tools:
    enabled: true
    shellcheck:
      enabled: true
    markdownlint:
      enabled: true
    languagetool:
      enabled: true
      language: en-US
    biome:
      enabled: true
    hadolint:
      enabled: true
    yamllint:
      enabled: true
    ruff:
      enabled: true
    eslint:
      enabled: false  # Disabled because we run ESLint in CI
    golangci-lint:
      enabled: true

Why use CodeRabbit’s linters

If your team already runs linters in CI, you might wonder why you would want CodeRabbit running them too. There are two practical reasons.

First, CodeRabbit’s linters provide feedback directly on the PR as inline comments, which is faster than waiting for a CI pipeline to complete and then scrolling through log output to find the relevant error. Developers see the issue in context, right on the line that caused it.

Second, CodeRabbit combines linter findings with its AI analysis. When a linter flags an issue, the AI can provide additional context about why the issue matters and suggest a fix that accounts for the surrounding code. This is more useful than a standalone linter message that just cites a rule number.

If you want to avoid duplicate feedback between CodeRabbit’s linters and your CI linters, disable the overlapping tools in .coderabbit.yaml and let your CI pipeline handle those specific checks.

Auto-review settings

The reviews.auto_review section controls when and how CodeRabbit automatically reviews pull requests.

reviews:
  auto_review:
    enabled: true
    drafts: false
    incremental_reviews: true

enabled

When set to true (the default), CodeRabbit automatically reviews every PR that is opened or updated. When set to false, reviews only happen when triggered manually with @coderabbitai review.

Setting this to false is useful for repositories where you only want AI review on specific PRs rather than every single one. Developers can then opt in to AI review by posting the review command.

drafts

When set to true, CodeRabbit reviews draft pull requests. The default is false, which means draft PRs are skipped until they are marked as ready for review.

Most teams keep this at false because draft PRs are often works in progress that change significantly before the developer considers them review-ready. Reviewing draft PRs generates comments on code that will likely be rewritten, which creates noise.

However, some teams set this to true because they want early feedback during development. If your workflow involves opening draft PRs as a way to get incremental feedback from both humans and tools, enabling draft review makes sense.

incremental_reviews

When set to true (the default), CodeRabbit reviews only the new changes when additional commits are pushed to an existing PR. When set to false, CodeRabbit re-reviews the entire PR on every push.

Incremental reviews are faster and produce less noise because they focus on what just changed. Full re-reviews are more thorough because they reconsider the entire diff in context. For most teams, incremental is the right choice.

Summary and walkthrough settings

Several fields control what CodeRabbit includes in its summary comment at the top of each PR:

reviews:
  high_level_summary: true
  high_level_summary_placeholder: "@coderabbitai summary"
  collapse_walkthrough: false
  sequence_diagrams: true
  changed_files_summary: true
  review_status: true
  poem: false

high_level_summary - When true, CodeRabbit posts a natural language summary of the PR changes. This is one of the most popular features because it helps reviewers quickly understand what a PR does without reading the diff.

collapse_walkthrough - When true, the file-by-file walkthrough section is collapsed by default in the summary comment. This keeps the summary compact while still making the detailed walkthrough available with a click.

sequence_diagrams - When true, CodeRabbit generates Mermaid sequence diagrams for PRs that involve request flows, API calls, or multi-step processes. These diagrams provide a visual overview that is especially helpful for complex PRs.

changed_files_summary - When true, the summary includes a table listing every changed file with a one-line description of what changed.

poem - When true, CodeRabbit includes a short poem summarizing the PR. This is a lighthearted feature that some teams enjoy and others find distracting. The default is false.

Knowledge base settings

knowledge_base:
  opt_out: false
  learnings:
    scope: auto

The knowledge base allows CodeRabbit to learn from your repository and your team’s feedback over time. When enabled, CodeRabbit builds context about your codebase patterns, naming conventions, architecture decisions, and review preferences.

The learnings.scope field controls how broadly CodeRabbit applies what it learns. Set to auto, it determines the appropriate scope automatically. Learnings from dismissed comments, accepted suggestions, and conversational corrections accumulate over time and improve review quality for subsequent PRs.

If your organization has data retention or privacy concerns about CodeRabbit storing repository context, set opt_out to true to disable the knowledge base entirely.

Example configs for different team sizes

  path_filters:
    - "!**/*.lock"
    - "!**/dist/**"
    - "!**/node_modules/**"
  instructions: |
    Focus only on bugs and security issues.
    Do not comment on style, naming, or documentation.

Advanced configuration tips

Reducing false positives

The most common complaint about any automated review tool is false positives - comments that are technically correct but not relevant to your project’s context. Here are the most effective ways to reduce them in CodeRabbit:

1. Tell CodeRabbit what not to review. Add explicit exclusions in your global instructions for things your other tools already handle. If ESLint enforces import ordering and Prettier handles formatting, say so in the instructions.

2. Add framework context. If your project uses Next.js App Router, tell CodeRabbit in the instructions. If you use a specific ORM, mention it. Without this context, CodeRabbit may flag patterns that are idiomatic in your framework.

3. Reply to false positives. When CodeRabbit posts an irrelevant comment, reply with an explanation of why it does not apply. CodeRabbit stores these as learnings and avoids similar suggestions in future reviews.

4. Use the chill profile. If the assertive profile generates too much noise, switching to chill immediately reduces comment volume by focusing only on high-severity issues.

Overriding configuration per PR

You cannot override .coderabbit.yaml on a per-PR basis through the configuration file itself. However, you can effectively customize review behavior for individual PRs by using the @coderabbitai chat commands. For example, posting @coderabbitai review - focus on security issues only on a specific PR tells CodeRabbit to adjust its focus for that particular review.

Validating your configuration

Before committing changes to .coderabbit.yaml, validate the YAML syntax using any standard YAML validator. Common mistakes include using tabs instead of spaces for indentation, missing colons after keys, and incorrect nesting depth.

After committing, post @coderabbitai configuration on any open PR to verify that CodeRabbit is reading your file correctly. The output shows the parsed configuration, any errors, and the effective settings.

Considering alternatives

While CodeRabbit is the most widely adopted AI code review tool, it is not the only option. If your team needs more than just PR reviews - such as SAST scanning, secret detection, infrastructure-as-code security, and engineering metrics in a single platform - CodeAnt AI offers a compelling alternative at $24-40/user/month. CodeAnt AI bundles AI-powered PR reviews with static analysis, secret detection, dead code removal, and DORA metrics dashboards, which can replace multiple tools in your pipeline. For teams that want a single platform covering both code review and security scanning, it is worth evaluating alongside CodeRabbit.

Putting your configuration into practice

Getting the most from your CodeRabbit configuration is an iterative process, not a one-time setup. Start with a minimal .coderabbit.yaml that sets the review profile and excludes obvious noise files. Run it for a week or two and observe which comments are helpful and which are irrelevant. Then expand the configuration by adding global instructions that address the most common false positives, path-specific instructions for your most critical code, and linter configuration that complements your existing CI pipeline.

The teams that get the most value from CodeRabbit are the ones that treat the .coderabbit.yaml file as a living document - updating it monthly based on team feedback, new project areas, and evolving coding standards. A well-maintained configuration file turns CodeRabbit from a generic automated reviewer into a context-aware team member that understands your specific codebase and review priorities.
