 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.

+### 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:

+             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
+
+For more information on creating GitHub Apps, see the [GitHub documentation](https://docs.github.com/en/apps/creating-github-apps).

 - **Perform Branch Operations**: Cannot merge branches, rebase, or perform other git operations beyond pushing commits
 
 ## Advanced Configuration
 
+### Additional Permissions for CI/CD Integration
+
+The `additional_permissions` input allows Claude to access GitHub Actions workflow information when you grant the necessary permissions. This is particularly useful for analyzing CI/CD failures and debugging workflow issues.
+
+#### Enabling GitHub Actions Access
+
+To allow Claude to view workflow run results, job logs, and CI status:
+
+1. **Grant the necessary permission to your GitHub token**:
+
+   - When using the default `GITHUB_TOKEN`, add the `actions: read` permission to your workflow:
+
+   ```yaml
+   permissions:
+     contents: write
+     pull-requests: write
+     issues: write
+     actions: read # Add this line
+   ```
+
+2. **Configure the action with additional permissions**:
+
+   ```yaml
+   - uses: anthropics/claude-code-action@beta
+     with:
+       anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+       additional_permissions: |
+         actions: read
+       # ... other inputs
+   ```
+
+3. **Claude will automatically get access to CI/CD tools**:
+   When you enable `actions: read`, Claude can use the following MCP tools:
+   - `mcp__github_ci__get_ci_status` - View workflow run statuses
+   - `mcp__github_ci__get_workflow_run_details` - Get detailed workflow information
+   - `mcp__github_ci__download_job_log` - Download and analyze job logs
+
+#### Example: Debugging Failed CI Runs
+
+```yaml
+name: Claude CI Helper
+on:
+  issue_comment:
+    types: [created]
+
+permissions:
+  contents: write
+  pull-requests: write
+  issues: write
+  actions: read # Required for CI access
+
+jobs:
+  claude-ci-helper:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: anthropics/claude-code-action@beta
+        with:
+          anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+          additional_permissions: |
+            actions: read
+          # Now Claude can respond to "@claude why did the CI fail?"
+```
+
+**Important Notes**:
+
+- The GitHub token must have the `actions: read` permission in your workflow
+- If the permission is missing, Claude will warn you and suggest adding it
+- Currently, only `actions: read` is supported, but the format allows for future extensions
+
+### Custom Environment Variables
+
+You can pass custom environment variables to Claude Code execution using the `claude_env` input. This is useful for CI/test setups that require specific environment variables:
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    claude_env: |
+      NODE_ENV: test
+      CI: true
+      DATABASE_URL: postgres://test:test@localhost:5432/test_db
+    # ... other inputs
+```
+
+The `claude_env` input accepts YAML format where each line defines a key-value pair. These environment variables will be available to Claude Code during execution, allowing it to run tests, build processes, or other commands that depend on specific environment configurations.
+
+### Limiting Conversation Turns
+
+You can use the `max_turns` parameter to limit the number of back-and-forth exchanges Claude can have during task execution. This is useful for:
+
+- Controlling costs by preventing runaway conversations
+- Setting time boundaries for automated workflows
+- Ensuring predictable behavior in CI/CD pipelines
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    max_turns: "5" # Limit to 5 conversation turns
+    # ... other inputs
+```
+
+When the turn limit is reached, Claude will stop execution gracefully. Choose a value that gives Claude enough turns to complete typical tasks while preventing excessive usage.

+### Network Restrictions
+
+For enhanced security, you can restrict Claude's network access to specific domains only. This feature is particularly useful for:
+
+- Enterprise environments with strict security policies
+- Preventing access to external services
+- Limiting Claude to only your internal APIs and services
+
+When `experimental_allowed_domains` is set, Claude can only access the domains you explicitly list. You'll need to include the appropriate provider domains based on your authentication method.
+
+#### Provider-Specific Examples
+
+##### If using Anthropic API or subscription
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    # Or: claude_code_oauth_token: ${{ secrets.CLAUDE_CODE_OAUTH_TOKEN }}
+    experimental_allowed_domains: |
+      .anthropic.com
+```
+
+##### If using AWS Bedrock
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    use_bedrock: "true"
+    experimental_allowed_domains: |
+      bedrock.*.amazonaws.com
+      bedrock-runtime.*.amazonaws.com
+```
+
+##### If using Google Vertex AI
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    use_vertex: "true"
+    experimental_allowed_domains: |
+      *.googleapis.com
+      vertexai.googleapis.com
+```
+
+#### Common GitHub Domains
+
+In addition to your provider domains, you may need to include GitHub-related domains. For GitHub.com users, common domains include:
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    experimental_allowed_domains: |
+      .anthropic.com  # For Anthropic API
+      .github.com
+      .githubusercontent.com
+      ghcr.io
+      .blob.core.windows.net
+```
+
+For GitHub Enterprise users, replace the GitHub.com domains above with your enterprise domains (e.g., `.github.company.com`, `packages.company.com`, etc.).
+
+To determine which domains your workflow needs, you can temporarily run without restrictions and monitor the network requests, or check your GitHub Enterprise configuration for the specific services you use.
+
+### Claude Code Settings
+
+You can provide Claude Code settings to customize behavior such as model selection, environment variables, permissions, and hooks. Settings can be provided either as a JSON string or a path to a settings file.
+
+#### Option 1: Settings File
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    settings: "path/to/settings.json"
+    # ... other inputs
+```
+
+#### Option 2: Inline Settings
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    settings: |
+      {
+        "model": "claude-opus-4-20250514",
+        "env": {
+          "DEBUG": "true",
+          "API_URL": "https://api.example.com"
+        },
+        "permissions": {
+          "allow": ["Bash", "Read"],
+          "deny": ["WebFetch"]
+        },
+        "hooks": {
+          "PreToolUse": [{
+            "matcher": "Bash",
+            "hooks": [{
+              "type": "command",
+              "command": "echo Running bash command..."
+            }]
+          }]
+        }
+      }
+    # ... other inputs
+```
+
+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.

+# Claude Code GitHub Action Roadmap
+
+Thank you for trying out the beta of our GitHub Action! This document outlines our path to `v1.0`. Items are not necessarily in priority order.
+
+## Path to 1.0
+
+- ~**Ability to see GitHub Action CI results** - This will enable Claude to look at CI failures and make updates to PRs to fix test failures, lint errors, and the like.~
+- **Cross-repo support** - Enable Claude to work across multiple repositories in a single session
+- **Ability to modify workflow files** - Let Claude update GitHub Actions workflows and other CI configuration files
+- **Support for workflow_dispatch and repository_dispatch events** - Dispatch Claude on events triggered via API from other workflows or from other services
+- **Ability to disable commit signing** - Option to turn off GPG signing for environments where it's not required. This will enable Claude to use normal `git` bash commands for committing. This will likely become the default behavior once added.
+- **Better code review behavior** - Support inline comments on specific lines, provide higher quality reviews with more actionable feedback
+- **Support triggering @claude from bot users** - Allow automation and bot accounts to invoke Claude
+- **Customizable base prompts** - Full control over Claude's initial context with template variables like `$PR_COMMENTS`, `$PR_FILES`, etc. Users can replace our default prompt entirely while still accessing key contextual data

+## 🚀 System Initialization
+
+**Available Tools:** 8 tools loaded
+
+---
+
+I'll help you with this task. Let me start by examining the file to understand what needs to be changed.
+
+### 🔧 `Read`
+
+**Parameters:**
+```json
+{
+  "file_path": "/path/to/sample/file.py"
+}
+```
+
+**Result:**
+```python
+def example_function():
+    print("Debug message")  # This should be removed
+    return "Hello World"
+
+if __name__ == "__main__":
+    result = example_function()
+    print(result)
+```
+
+*Token usage: 100 input, 75 output*
+
+---
+
+I can see the debug print statement that needs to be removed. Let me fix this by editing the file.
+
+### 🔧 `Edit`
+
+**Parameters:**
+```json
+{
+  "file_path": "/path/to/sample/file.py",
+  "old_string": "def example_function():\n    print(\"Debug message\")  # This should be removed\n    return \"Hello World\"",
+  "new_string": "def example_function():\n    return \"Hello World\""
+}
+```
+
+**→** File successfully edited. The debug print statement has been removed.
+
+*Token usage: 200 input, 50 output*
+
+---
+
+Perfect! I've successfully removed the debug print statement from the function. Let me now create a pull request comment to document this change.
+
+### 🔧 `mcp__github__add_pull_request_review_comment`
+
+**Parameters:**
+```json
+{
+  "owner": "example-org",
+  "repo": "example-repo",
+  "pull_number": 123,
+  "body": "Removed debug print statement as requested.",
+  "commit_id": "abc123def456",
+  "path": "sample/file.py",
+  "line": 2
+}
+```
+
+**→** Successfully posted review comment to PR #123
+
+*Token usage: 150 input, 80 output*
+
+---
+
+Great! I've successfully completed the requested task:
+
+1. ✅ Located the debug print statement in the file
+2. ✅ Removed the print statement while preserving the function logic
+3. ✅ Added a review comment documenting the change
+
+The debug print statement has been removed as requested by the reviewers.
+
+*Token usage: 180 input, 60 output*
+
+---
+
+## ✅ Final Result
+
+Successfully removed debug print statement from file and added review comment to document the change.
+
+**Cost:** $0.0347 | **Duration:** 18.8s
