 Claude doesn't create PRs by default. Instead, it pushes commits to a branch and provides a link to a pre-filled PR submission page. This approach ensures your repository's branch protection rules are still adhered to and gives you final control over PR creation.
 
-### Can Claude see my GitHub Actions CI results?
+### Why can't Claude run my tests or see CI results?
 
-Yes! Claude can access GitHub Actions workflow runs, job logs, and test results on the PR where it's tagged. To enable this:
+Claude cannot access GitHub Actions logs, test results, or other CI/CD outputs by default. It only has access to the repository files. If you need Claude to see test results, you can either:
 
-1. Add `actions: read` permission to your workflow:
+1. Instruct Claude to run tests before making commits
+2. Copy and paste CI results into a comment for Claude to analyze
 
-   ```yaml
-   permissions:
-     contents: write
-     pull-requests: write
-     issues: write
-     actions: read
-   ```
-
-2. Configure the action with additional permissions:
-   ```yaml
-   - uses: anthropics/claude-code-action@beta
-     with:
-       additional_permissions: |
-         actions: read
-   ```
-
-Claude will then be able to analyze CI failures and help debug workflow issues. For running tests locally before commits, you can still instruct Claude to do so in your request.
+This limitation exists for security reasons but may be reconsidered in the future based on user feedback.
 
 ### Why does Claude only update one comment instead of creating new ones?

-### Using a Custom GitHub App
-
-If you prefer not to install the official Claude app, you can create your own GitHub App to use with this action. This gives you complete control over permissions and access.
-
-**When you may want to use a custom GitHub App:**
-
-- You need more restrictive permissions than the official app
-- Organization policies prevent installing third-party apps
-- You're using AWS Bedrock or Google Vertex AI
-
-**Steps to create and use a custom GitHub App:**
-
-1. **Create a new GitHub App:**
-
-   - Go to https://github.com/settings/apps (for personal apps) or your organization's settings
-   - Click "New GitHub App"
-   - Configure the app with these minimum permissions:
-     - **Repository permissions:**
-       - Contents: Read & Write
-       - Issues: Read & Write
-       - Pull requests: Read & Write
-     - **Account permissions:** None required
-   - Set "Where can this GitHub App be installed?" to your preference
-   - Create the app
-
-2. **Generate and download a private key:**
-
-   - After creating the app, scroll down to "Private keys"
-   - Click "Generate a private key"
-   - Download the `.pem` file (keep this secure!)
-
-3. **Install the app on your repository:**
-
-   - Go to the app's settings page
-   - Click "Install App"
-   - Select the repositories where you want to use Claude
-
-4. **Add the app credentials to your repository secrets:**
-
-   - Go to your repository's Settings → Secrets and variables → Actions
-   - Add these secrets:
-     - `APP_ID`: Your GitHub App's ID (found in the app settings)
-     - `APP_PRIVATE_KEY`: The contents of the downloaded `.pem` file
-
-5. **Update your workflow to use the custom app:**
-
-   ```yaml
-   name: Claude with Custom App
-   on:
-     issue_comment:
-       types: [created]
-     # ... other triggers
-
-   jobs:
-     claude-response:
-       runs-on: ubuntu-latest
-       steps:
-         # Generate a token from your custom app
-         - name: Generate GitHub App token
-           id: app-token
-           uses: actions/create-github-app-token@v1
-           with:
-             app-id: ${{ secrets.APP_ID }}
-             private-key: ${{ secrets.APP_PRIVATE_KEY }}
-
-         # Use Claude with your custom app's token
-         - uses: anthropics/claude-code-action@beta
-           with:
-             anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-             github_token: ${{ steps.app-token.outputs.token }}
-             # ... other configuration
-   ```
-
-**Important notes:**
-
-- The custom app must have read/write permissions for Issues, Pull Requests, and Contents
-- Your app's token will have the exact permissions you configured, nothing more
-

-

-The settings support all Claude Code settings options including:
-
-- `model`: Override the default model
-- `env`: Environment variables for the session
-- `permissions`: Tool usage permissions
-- `hooks`: Pre/post tool execution hooks
-- And more...
-
-For a complete list of available settings and their descriptions, see the [Claude Code settings documentation](https://docs.anthropic.com/en/docs/claude-code/settings).
-
-**Notes**:
-
-- The `enableAllProjectMcpServers` setting is always set to `true` by this action to ensure MCP servers work correctly.
-- If both the `model` input parameter and a `model` in settings are provided, the `model` input parameter takes precedence.
-- The `allowed_tools` and `disallowed_tools` input parameters take precedence over `permissions` in settings.
-- In a future version, we may deprecate individual input parameters in favor of using the settings file for all configuration.
