fix: prevent path traversal in delete_files MCP tool

The delete_files tool only validated absolute paths starting with "/",
allowing relative paths with traversal sequences like "./../../sensitive"
to bypass validation.

Now all paths are normalized using path.resolve() before validation,
ensuring both absolute and relative paths with ".." sequences are
properly blocked from accessing files outside the repository root.

+You are an elite security code reviewer with deep expertise in application security, threat modeling, and secure coding practices. Your mission is to identify and prevent security vulnerabilities before they reach production.
+
+When reviewing code, you will:
+
+**Security Vulnerability Assessment**
+
+- Systematically scan for OWASP Top 10 vulnerabilities (injection flaws, broken authentication, sensitive data exposure, XXE, broken access control, security misconfiguration, XSS, insecure deserialization, using components with known vulnerabilities, insufficient logging)
+- Identify potential SQL injection, NoSQL injection, and command injection vulnerabilities
+- Check for cross-site scripting (XSS) vulnerabilities in any user-facing output
+- Look for cross-site request forgery (CSRF) protection gaps
+- Examine cryptographic implementations for weak algorithms or improper key management
+- Identify potential race conditions and time-of-check-time-of-use (TOCTOU) vulnerabilities
+
+**Input Validation and Sanitization**
+
+- Verify all user inputs are properly validated against expected formats and ranges
+- Ensure input sanitization occurs at appropriate boundaries (client-side validation is supplementary, never primary)
+- Check for proper encoding when outputting user data
+- Validate that file uploads have proper type checking, size limits, and content validation
+- Ensure API parameters are validated for type, format, and business logic constraints
+- Look for potential path traversal vulnerabilities in file operations
+
+**Authentication and Authorization Review**
+
+- Verify authentication mechanisms use secure, industry-standard approaches
+- Check for proper session management (secure cookies, appropriate timeouts, session invalidation)
+- Ensure passwords are properly hashed using modern algorithms (bcrypt, Argon2, PBKDF2)
+- Validate that authorization checks occur at every protected resource access
+- Look for privilege escalation opportunities
+- Check for insecure direct object references (IDOR)
+- Verify proper implementation of role-based or attribute-based access control
+
+**Analysis Methodology**
+
+1. First, identify the security context and attack surface of the code
+2. Map data flows from untrusted sources to sensitive operations
+3. Examine each security-critical operation for proper controls
+4. Consider both common vulnerabilities and context-specific threats
+5. Evaluate defense-in-depth measures
+
+**Review Structure:**
+Provide findings in order of severity (Critical, High, Medium, Low, Informational):
+
+- **Vulnerability Description**: Clear explanation of the security issue
+- **Location**: Specific file, function, and line numbers
+- **Impact**: Potential consequences if exploited
+- **Remediation**: Concrete steps to fix the vulnerability with code examples when helpful
+- **References**: Relevant CWE numbers or security standards
+
+If no security issues are found, provide a brief summary confirming the review was completed and highlighting any positive security practices observed.
+
+Always consider the principle of least privilege, defense in depth, and fail securely. When uncertain about a potential vulnerability, err on the side of caution and flag it for further investigation.

-             - Select priority labels if you can determine urgency (high-priority, med-priority, or low-priority)
-             - Consider platform labels (android, ios) if applicable
-             - If you find similar issues using mcp__github__search_issues, consider using a "duplicate" label if appropriate. Only do so if the issue is a duplicate of another OPEN issue.
-
-          5. Apply the selected labels:
-             - Use mcp__github__update_issue to apply your selected labels
-             - DO NOT post any comments explaining your decision
-             - DO NOT communicate directly with users
-             - If no labels are clearly applicable, do not apply any labels
-
-          IMPORTANT GUIDELINES:
-          - Be thorough in your analysis
-          - Only select labels from the provided list above
-          - DO NOT post any comments to the issue
-          - Your ONLY action should be to apply labels using mcp__github__update_issue
-          - It's okay to not add any labels if none are clearly applicable

 # Claude Code Action
 
-A general-purpose [Claude Code](https://claude.ai/code) action for GitHub PRs and issues that can answer questions and implement code changes. This action listens for a trigger phrase in comments and activates Claude act on the request. It supports multiple authentication methods including Anthropic direct API, Amazon Bedrock, and Google Vertex AI.
+A general-purpose [Claude Code](https://claude.ai/code) action for GitHub PRs and issues that can answer questions and implement code changes. This action intelligently detects when to activate based on your workflow context—whether responding to @claude mentions, issue assignments, or executing automation tasks with explicit prompts. It supports multiple authentication methods including Anthropic direct API, Amazon Bedrock, Google Vertex AI, and Microsoft Foundry.
 
 ## Features
 
+- 🎯 **Intelligent Mode Detection**: Automatically selects the appropriate execution mode based on your workflow context—no configuration needed
 - 🤖 **Interactive Code Assistant**: Claude can answer questions about code, architecture, and programming
 - 🔍 **Code Review**: Analyzes PR changes and suggests improvements
 - ✨ **Code Implementation**: Can implement simple fixes, refactoring, and even new features
 - 💬 **PR/Issue Integration**: Works seamlessly with GitHub comments and PR reviews
 - 🛠️ **Flexible Tool Access**: Access to GitHub APIs and file operations (additional tools can be enabled via configuration)
 - 📋 **Progress Tracking**: Visual progress indicators with checkboxes that dynamically update as Claude completes tasks
+- 📊 **Structured Outputs**: Get validated JSON results that automatically become GitHub Action outputs for complex automations
 - 🏃 **Runs on Your Infrastructure**: The action executes entirely on your own GitHub runner (Anthropic API calls go to your chosen provider)
+- ⚙️ **Simplified Configuration**: Unified `prompt` and `claude_args` inputs provide clean, powerful configuration aligned with Claude Code SDK
 
-## ⚠️ **BREAKING CHANGES COMING IN v1.0** ⚠️
+## 📦 Upgrading from v0.x?
 
-**We're planning a major update that will significantly change how this action works.** The new version will:
-
-- ✨ Automatically select the appropriate mode (no more `mode` input)
-- 🔧 Simplify configuration with unified `prompt` and `claude_args`
-- 🚀 Align more closely with the Claude Code SDK capabilities
-- 💥 Remove multiple inputs like `direct_prompt`, `custom_instructions`, and others
-
-**[→ Read the full v1.0 roadmap and provide feedback](https://github.com/anthropics/claude-code-action/discussions/428)**
-
----
+**See our [Migration Guide](./docs/migration-guide.md)** for step-by-step instructions on updating your workflows to v1.0. The new version simplifies configuration while maintaining compatibility with most existing setups.

+| Old Input             | New Approach                                             |
+| --------------------- | -------------------------------------------------------- |
+| `allowed_tools`       | Use `claude_args: "--allowedTools Tool1,Tool2"`          |
+| `disallowed_tools`    | Use `claude_args: "--disallowedTools Tool1,Tool2"`       |
+| `max_turns`           | Use `claude_args: "--max-turns 10"`                      |
+| `model`               | Use `claude_args: "--model claude-4-0-sonnet-20250805"`  |
+| `claude_env`          | Use `settings` with `"env"` object                       |
+| `custom_instructions` | Use `claude_args: "--system-prompt 'Your instructions'"` |
+| `mcp_config`          | Use `claude_args: "--mcp-config '{...}'"`                |
+| `direct_prompt`       | Use `prompt` input instead                               |
+| `override_prompt`     | Use `prompt` with GitHub context variables               |
+
+## Custom Executables for Specialized Environments
+
+For specialized environments like Nix, custom container setups, or other package management systems where the default installation doesn't work, you can provide your own executables:
+
+### Custom Claude Code Executable
+
+Use `path_to_claude_code_executable` to provide your own Claude Code binary instead of using the automatically installed version:
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    path_to_claude_code_executable: "/path/to/custom/claude"
+    # ... other inputs
+```
+
+### Custom Bun Executable
+
+Use `path_to_bun_executable` to provide your own Bun runtime instead of the default installation:
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    path_to_bun_executable: "/path/to/custom/bun"
+    # ... other inputs
+```
+
+**Important**: Using incompatible versions may cause the action to fail. Ensure your custom executables are compatible with the action's requirements.

 # Custom Automations
 
-These examples show how to configure Claude to act automatically based on GitHub events, without requiring manual @mentions.
+These examples show how to configure Claude to act automatically based on GitHub events. When you provide a `prompt` input, the action automatically runs in agent mode without requiring manual @mentions. Without a `prompt`, it runs in interactive mode, responding to @claude mentions.
+
+## Mode Detection & Tracking Comments
+
+The action automatically detects which mode to use based on your configuration:
+
+- **Interactive Mode** (no `prompt` input): Responds to @claude mentions, creates tracking comments with progress indicators
+- **Automation Mode** (with `prompt` input): Executes immediately, **does not create tracking comments**
+
+> **Note**: In v1, automation mode intentionally does not create tracking comments by default to reduce noise in automated workflows. If you need progress tracking, use the `track_progress: true` input parameter.
 
 ## Supported GitHub Events
 
 This action supports the following GitHub events ([learn more GitHub event triggers](https://docs.github.com/en/actions/writing-workflows/choosing-when-your-workflow-runs/events-that-trigger-workflows)):
 
-- `pull_request` - When PRs are opened or synchronized
+- `pull_request` or `pull_request_target` - When PRs are opened or synchronized
 - `issue_comment` - When comments are created on issues or PRs
 - `pull_request_comment` - When comments are made on PR diffs
 - `issues` - When issues are opened or assigned
 - `pull_request_review` - When PR reviews are submitted
 - `pull_request_review_comment` - When comments are made on PR reviews
-- `repository_dispatch` - Custom events triggered via API (coming soon)
+- `repository_dispatch` - Custom events triggered via API
 - `workflow_dispatch` - Manual workflow triggers (coming soon)

-## Execution Modes
+## Automatic Mode Detection
 
-The action supports three execution modes, each optimized for different use cases:
+The action intelligently detects the appropriate execution mode based on your workflow context, eliminating the need for manual mode configuration.
 
-### Tag Mode (Default)
+### Interactive Mode (Tag Mode)
 
-The traditional implementation mode that responds to @claude mentions, issue assignments, or labels.
+Activated when Claude detects @mentions, issue assignments, or labels—without an explicit `prompt`.
 
-- **Triggers**: `@claude` mentions, issue assignment, label application
+- **Triggers**: `@claude` mentions in comments, issue assignment to claude user, label application
 - **Features**: Creates tracking comments with progress checkboxes, full implementation capabilities
-- **Use case**: General-purpose code implementation and Q&A
+- **Use case**: Interactive code assistance, Q&A, and implementation requests
 
 ```yaml
-- uses: anthropics/claude-code-action@beta
+- uses: anthropics/claude-code-action@v1
   with:

+### Automation Mode (Agent Mode)
 
-**Note: Agent mode is currently in active development and may undergo breaking changes.**
+Automatically activated when you provide a `prompt` input.
 
-For automation with workflow_dispatch and scheduled events only.
-
-- **Triggers**: Only works with `workflow_dispatch` and `schedule` events - does NOT work with PR/issue events
-- **Features**: Perfect for scheduled tasks, works with `override_prompt`
-- **Use case**: Maintenance tasks, automated reporting, scheduled checks
+- **Triggers**: Any GitHub event when `prompt` input is provided
+- **Features**: Direct execution without requiring @claude mentions, streamlined for automation
+- **Use case**: Automated PR reviews, scheduled tasks, workflow automation
 
 ```yaml
-- uses: anthropics/claude-code-action@beta
+- uses: anthropics/claude-code-action@v1

-    override_prompt: |
+    prompt: |
       Check for outdated dependencies and create an issue if any are found.
+    # Automatically runs in agent mode when prompt is provided
 ```
 
-### Experimental Review Mode
+### How It Works
 
-**Warning: This is an experimental feature that may change or be removed at any time.**
+The action uses this logic to determine the mode:
 
-For automated code reviews on pull requests.
+1. **If `prompt` is provided** → Runs in **agent mode** for automation
+2. **If no `prompt` but @claude is mentioned** → Runs in **tag mode** for interaction
+3. **If neither** → No action is taken
 
-- **Triggers**: Pull request events (`opened`, `synchronize`) or `@claude review` comments
-- **Features**: Provides detailed code reviews with inline comments and suggestions
-- **Use case**: Automated PR reviews, code quality checks
+This automatic detection ensures your workflows are simpler and more intuitive, without needing to understand or configure different modes.
+
+### Advanced Mode Control
+
+For specialized use cases, you can fine-tune behavior using `claude_args`:
 
 ```yaml
-- uses: anthropics/claude-code-action@beta
+- uses: anthropics/claude-code-action@v1
   with:
-    mode: experimental-review
+    prompt: "Review this PR"
+    claude_args: |
+      --max-turns 20
+      --system-prompt "You are a code review specialist"
     anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-    custom_instructions: |
-      Focus on code quality, security, and best practices.
 ```
-
-See [`examples/claude-modes.yml`](../examples/claude-modes.yml) and [`examples/claude-experimental-review-mode.yml`](../examples/claude-experimental-review-mode.yml) for complete examples of each mode.
-
-## 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.

-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.

 The OIDC token is required in order for the Claude GitHub app to function. If you wish to not use the GitHub app, you can instead provide a `github_token` input to the action for Claude to operate with. See the [Claude Code permissions documentation][perms] for more.
 
+### Why am I getting '403 Resource not accessible by integration' errors?
+
+This error occurs when the action tries to fetch the authenticated user information using a GitHub App installation token. GitHub App tokens have limited access and cannot access the `/user` endpoint, which causes this 403 error.

 ## Configuration and Tools
 
-### What's the difference between `direct_prompt` and `custom_instructions`?
+### How does automatic mode detection work?
 
-These inputs serve different purposes in how Claude responds:
+The action intelligently detects whether to run in interactive mode or automation mode:
 
-- **`direct_prompt`**: Bypasses trigger detection entirely. When provided, Claude executes this exact instruction regardless of comments or mentions. Perfect for automated workflows where you want Claude to perform a specific task on every run (e.g., "Update the API documentation based on changes in this PR").
+- **With `prompt` input**: Runs in automation mode - executes immediately without waiting for @claude mentions
+- **Without `prompt` input**: Runs in interactive mode - waits for @claude mentions in comments
 
-- **`custom_instructions`**: Additional context added to Claude's system prompt while still respecting normal triggers. These instructions modify Claude's behavior but don't replace the triggering comment. Use this to give Claude standing instructions like "You have been granted additional tools for ...".
+This automatic detection eliminates the need to manually configure modes.
 
 Example:
 
 ```yaml
-# Using direct_prompt - runs automatically without @claude mention
-direct_prompt: "Review this PR for security vulnerabilities"
+# Automation mode - runs automatically
+prompt: "Review this PR for security vulnerabilities"
+# Interactive mode - waits for @claude mention
+# (no prompt provided)
+```
 
-# Using custom_instructions - still requires @claude trigger
-custom_instructions: "Focus on performance implications and suggest optimizations"
+### What happened to `direct_prompt` and `custom_instructions`?
+
+**These inputs are deprecated in v1.0:**
+
+- **`direct_prompt`** → Use `prompt` instead
+- **`custom_instructions`** → Use `claude_args` with `--system-prompt`

+## Migration Examples
+
+### Basic Interactive Workflow (@claude mentions)
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    mode: "tag"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    custom_instructions: "Follow our coding standards"
+    max_turns: "10"
+    allowed_tools: "Edit,Read,Write"
+```
+
+**After (v1.0):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    claude_args: |
+      --max-turns 10
+      --system-prompt "Follow our coding standards"
+      --allowedTools Edit,Read,Write
+```
+
+### Automation Workflow
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    mode: "agent"
+    direct_prompt: "Review this PR for security issues"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    model: "claude-3-5-sonnet-20241022"
+    allowed_tools: "Edit,Read,Write"
+```
+
+**After (v1.0):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    prompt: |
+      REPO: ${{ github.repository }}
+      PR NUMBER: ${{ github.event.pull_request.number }}
+
+      Review this PR for security issues
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    claude_args: |
+      --model claude-4-0-sonnet-20250805
+      --allowedTools Edit,Read,Write
+```
+
+> **⚠️ Important**: For PR reviews, always include the repository and PR context in your prompt. This ensures Claude knows which PR to review.
+
+### Automation with Progress Tracking (New in v1.0)
+
+**Missing the tracking comments from v0.x agent mode?** The new `track_progress` input brings them back!
+
+In v1.0, automation mode (with `prompt` input) doesn't create tracking comments by default to reduce noise. However, if you need progress visibility, you can use the `track_progress` feature:
+
+**Before (v0.x with tracking):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    mode: "agent"
+    direct_prompt: "Review this PR for security issues"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+**After (v1.0 with tracking):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    track_progress: true # Forces tag mode with tracking comments
+    prompt: |
+      REPO: ${{ github.repository }}
+      PR NUMBER: ${{ github.event.pull_request.number }}
+
+      Review this PR for security issues
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+#### Benefits of `track_progress`
+
+1. **Preserves GitHub Context**: Automatically includes all PR/issue details, comments, and attachments
+2. **Brings Back Tracking Comments**: Creates progress indicators just like v0.x agent mode
+3. **Works with Custom Prompts**: Your `prompt` is injected as custom instructions while maintaining context
+
+#### Supported Events for `track_progress`
+
+The `track_progress` input only works with these GitHub events:
+
+**Pull Request Events:**
+
+- `opened` - New PR created
+- `synchronize` - PR updated with new commits
+- `ready_for_review` - Draft PR marked as ready
+- `reopened` - Previously closed PR reopened
+
+**Issue Events:**
+
+- `opened` - New issue created
+- `edited` - Issue title or body modified
+- `labeled` - Label added to issue
+- `assigned` - Issue assigned to user
+
+> **Note**: Using `track_progress: true` with unsupported events will cause an error.
+
+### Custom Template with Variables
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    override_prompt: |
+      Analyze PR #$PR_NUMBER in $REPOSITORY
+      Changed files: $CHANGED_FILES
+      Focus on security vulnerabilities
+```
+
+**After (v1.0):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    prompt: |
+      REPO: ${{ github.repository }}
+      PR NUMBER: ${{ github.event.pull_request.number }}
+
+      Analyze this pull request focusing on security vulnerabilities in the changed files.
+
+      Note: The PR branch is already checked out in the current working directory.
+```
+
+> **💡 Tip**: While you can access GitHub context variables in your prompt, it's recommended to use the standard `REPO:` and `PR NUMBER:` format for consistency.
+
+### Environment Variables
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    claude_env: |
+      NODE_ENV: test
+      CI: true
+```
+
+**After (v1.0):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    settings: |
+      {
+        "env": {
+          "NODE_ENV": "test",
+          "CI": "true"
+        }
+      }
+```
+
+### Timeout Configuration
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    timeout_minutes: 30
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+**After (v1.0):**
+
+```yaml
+jobs:
+  claude-task:
+    runs-on: ubuntu-latest
+    timeout-minutes: 30 # Moved to job level
+    steps:
+      - uses: anthropics/claude-code-action@v1
+        with:
+          anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+```
+
+## How Mode Detection Works
+
+The action now automatically detects the appropriate mode:
+
+1. **If `prompt` is provided** → Runs in **automation mode**
+
+   - Executes immediately without waiting for @claude mentions
+   - Perfect for scheduled tasks, PR automation, etc.
+
+2. **If no `prompt` but @claude is mentioned** → Runs in **interactive mode**
+
+   - Waits for and responds to @claude mentions
+   - Creates tracking comments with progress
+
+3. **If neither** → No action is taken
+
+## Advanced Configuration with claude_args
+
+The `claude_args` input provides direct access to Claude Code CLI arguments:
+
+```yaml
+claude_args: |
+  --max-turns 15
+  --model claude-4-0-sonnet-20250805
+  --allowedTools Edit,Read,Write,Bash
+  --disallowedTools WebSearch
+  --system-prompt "You are a senior engineer focused on code quality"
+  --mcp-config '{"mcpServers": {"custom": {"command": "npx", "args": ["-y", "@example/server"]}}}'
+```
+
+### Common claude_args Options
+
+| Option              | Description              | Example                                |
+| ------------------- | ------------------------ | -------------------------------------- |
+| `--max-turns`       | Limit conversation turns | `--max-turns 10`                       |
+| `--model`           | Specify Claude model     | `--model claude-4-0-sonnet-20250805`   |
+| `--allowedTools`    | Enable specific tools    | `--allowedTools Edit,Read,Write`       |
+| `--disallowedTools` | Disable specific tools   | `--disallowedTools WebSearch`          |
+| `--system-prompt`   | Add system instructions  | `--system-prompt "Focus on security"`  |
+| `--mcp-config`      | Add MCP server config    | `--mcp-config '{"mcpServers": {...}}'` |

+
+## ⚠️ Full Output Security Warning
+
+The `show_full_output` option is **disabled by default** for security reasons. When enabled, it outputs ALL Claude Code messages including:
+
+- Full outputs from tool executions (e.g., `ps`, `env`, file reads)
+- API responses that may contain tokens or credentials
+- File contents that may include secrets
+- Command outputs that may expose sensitive system information
+
+**These logs are publicly visible in GitHub Actions for public repositories!**
+
+### Automatic Enabling in Debug Mode
+
+Full output is **automatically enabled** when GitHub Actions debug mode is active (when `ACTIONS_STEP_DEBUG` secret is set to `true`). This helps with debugging but carries the same security risks.
+
+### When to Enable Full Output
+
+Only enable `show_full_output: true` or GitHub Actions debug mode when:
+
+- Working in a private repository with controlled access
+- Debugging issues in a non-production environment
+- You have verified no secrets will be exposed in the output
+- You understand the security implications
+
+### Recommended Practice
+
+For debugging, prefer using `show_full_output: false` (the default) and rely on Claude Code's sanitized output, which shows only essential information like errors and completion status without exposing sensitive data.

-**Steps to create and use a custom GitHub App:**
+### Option 1: Quick Setup with App Manifest (Recommended)
+
+The fastest way to create a custom GitHub App is using our pre-configured manifest. This ensures all permissions are correctly set up with a single click.
+
+**Steps:**
+
+1. **Create the app:**
+
+   **🚀 [Download the Quick Setup Tool](./create-app.html)** (Right-click → "Save Link As" or "Download Linked File")
+
+   After downloading, open `create-app.html` in your web browser:
+
+   - **For Personal Accounts:** Click the "Create App for Personal Account" button
+   - **For Organizations:** Enter your organization name and click "Create App for Organization"
+
+   The tool will automatically configure all required permissions and submit the manifest.
+
+   Alternatively, you can use the manifest file directly:
+
+   - Use the [`github-app-manifest.json`](../github-app-manifest.json) file from this repository
+   - Visit https://github.com/settings/apps/new (for personal) or your organization's app settings
+   - Look for the "Create from manifest" option and paste the JSON content
+
+2. **Complete the creation flow:**
+
+   - GitHub will show you a preview of the app configuration
+   - Confirm the app name (you can customize it)
+   - Click "Create GitHub App"
+   - The app will be created with all required permissions automatically configured
+
+3. **Generate and download a private key:**
+
+   - After creating the app, you'll be redirected to the app settings
+   - Scroll down to "Private keys"
+   - Click "Generate a private key"
+   - Download the `.pem` file (keep this secure!)
+
+4. **Continue with installation** - Skip to step 3 in the manual setup below to install the app and configure your workflow.
+
+### Option 2: Manual Setup
+
+If you prefer to configure the app manually or need custom permissions:

+## Automatic PR Code Review
+
+**When to use:** Automatically review every PR opened or updated in your repository.
+
+### Basic Example (No Tracking)
+
+```yaml
+name: Claude Auto Review
+on:
+  pull_request:
+    types: [opened, synchronize]
+
+jobs:
+  review:
+    runs-on: ubuntu-latest
+    permissions:
+      contents: read
+      pull-requests: write
+      id-token: write
+    steps:
+      - uses: actions/checkout@v5
+        with:
+          fetch-depth: 1
+
+      - uses: anthropics/claude-code-action@v1
+        with:
+          anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+          prompt: |
+            REPO: ${{ github.repository }}
+            PR NUMBER: ${{ github.event.pull_request.number }}
+
+            Please review this pull request with a focus on:
+            - Code quality and best practices
+            - Potential bugs or issues
+            - Security implications
+            - Performance considerations
+
+            Note: The PR branch is already checked out in the current working directory.
+
+            Use `gh pr comment` for top-level feedback.
+            Use `mcp__github_inline_comment__create_inline_comment` to highlight specific code issues.
+            Only post GitHub comments - don't submit review text as messages.
+
+          claude_args: |
+            --allowedTools "mcp__github_inline_comment__create_inline_comment,Bash(gh pr comment:*),Bash(gh pr diff:*),Bash(gh pr view:*)"
+```
+
+**Key Configuration:**
+
+- Triggers on `opened` and `synchronize` (new commits)
+- Always include `REPO` and `PR NUMBER` for context
+- Specify tools for commenting and reviewing
+- PR branch is pre-checked out
+
+**Expected Output:** Claude posts review comments directly to the PR with inline annotations where appropriate.
+
+### Enhanced Example (With Progress Tracking)
+
+Want visual progress tracking for PR reviews? Use `track_progress: true` to get tracking comments like in v0.x:
+
+```yaml
+name: Claude Auto Review with Tracking
+on:
+  pull_request:
+    types: [opened, synchronize, ready_for_review, reopened]
+
+jobs:
+  review:
+    runs-on: ubuntu-latest
+    permissions:
+      contents: read
+      pull-requests: write
+      id-token: write
+    steps:
+      - uses: actions/checkout@v5
+        with:
+          fetch-depth: 1
+
+      - uses: anthropics/claude-code-action@v1
+        with:
+          anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+          track_progress: true # ✨ Enables tracking comments
+          prompt: |
+            REPO: ${{ github.repository }}
+            PR NUMBER: ${{ github.event.pull_request.number }}
+
+            Please review this pull request with a focus on:
+            - Code quality and best practices
+            - Potential bugs or issues
+            - Security implications
+            - Performance considerations
+
+            Provide detailed feedback using inline comments for specific issues.

+            --allowedTools "mcp__github_inline_comment__create_inline_comment,Bash(gh pr comment:*),Bash(gh pr diff:*),Bash(gh pr view:*)"
+```
+
+**Benefits of Progress Tracking:**
+
+- **Visual Progress Indicators**: Shows "In progress" status with checkboxes
+- **Preserves Full Context**: Automatically includes all PR details, comments, and attachments
+- **Migration-Friendly**: Perfect for teams moving from v0.x who miss tracking comments
+- **Works with Custom Prompts**: Your prompt becomes custom instructions while maintaining GitHub context
+
+**Expected Output:**
+
+1. Claude creates a tracking comment: "Claude Code is reviewing this pull request..."
+2. Updates the comment with progress checkboxes as it works
+3. Posts detailed review feedback with inline annotations
+4. Updates tracking comment to "Completed" when done

 > **Note**: This action is currently in beta. Features and APIs may change as we continue to improve the integration.
 
+## Upgrading from v0.x?
+
+For a comprehensive guide on migrating from v0.x to v1.0, including step-by-step instructions and examples, see our **[Migration Guide](./migration-guide.md)**.
+
+### Quick Migration Examples
+
+#### Interactive Workflows (with @claude mentions)
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    mode: "tag"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    custom_instructions: "Focus on security"
+    max_turns: "10"
+```
+
+**After (v1.0):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    claude_args: |
+      --max-turns 10
+      --system-prompt "Focus on security"
+```
+
+#### Automation Workflows
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    mode: "agent"
+    direct_prompt: "Update the API documentation"
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    model: "claude-4-0-sonnet-20250805"
+    allowed_tools: "Edit,Read,Write"
+```
+
+**After (v1.0):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    prompt: |
+      REPO: ${{ github.repository }}
+      PR NUMBER: ${{ github.event.pull_request.number }}
+
+      Update the API documentation to reflect changes in this PR
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    claude_args: |
+      --model claude-4-0-sonnet-20250805
+      --allowedTools Edit,Read,Write
+```
+
+#### Custom Templates
+
+**Before (v0.x):**
+
+```yaml
+- uses: anthropics/claude-code-action@beta
+  with:
+    override_prompt: |
+      Analyze PR #$PR_NUMBER for security issues.
+      Focus on: $CHANGED_FILES
+```
+
+**After (v1.0):**
+
+```yaml
+- uses: anthropics/claude-code-action@v1
+  with:
+    prompt: |
+      Analyze PR #${{ github.event.pull_request.number }} for security issues.
+      Focus on the changed files in this PR.
+```
+
+## Structured Outputs
+
+Get validated JSON results from Claude that automatically become GitHub Action outputs. This enables building complex automation workflows where Claude analyzes data and subsequent steps use the results.
+
+### Basic Example
+
+```yaml
+- name: Detect flaky tests
+  id: analyze
+  uses: anthropics/claude-code-action@v1
+  with:
+    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
+    prompt: |
+      Check the CI logs and determine if this is a flaky test.
+      Return: is_flaky (boolean), confidence (0-1), summary (string)
+    claude_args: |
+      --json-schema '{"type":"object","properties":{"is_flaky":{"type":"boolean"},"confidence":{"type":"number"},"summary":{"type":"string"}},"required":["is_flaky"]}'
+
+- name: Retry if flaky
+  if: fromJSON(steps.analyze.outputs.structured_output).is_flaky == true
+  run: gh workflow run CI
+```
+
+### How It Works
+
+1. **Define Schema**: Provide a JSON schema via `--json-schema` flag in `claude_args`
+2. **Claude Executes**: Claude uses tools to complete your task
+3. **Validated Output**: Result is validated against your schema
+4. **JSON Output**: All fields are returned in a single `structured_output` JSON string
+
+### Accessing Structured Outputs
+
+All structured output fields are available in the `structured_output` output as a JSON string:
+
+**In GitHub Actions expressions:**
+
+```yaml
+if: fromJSON(steps.analyze.outputs.structured_output).is_flaky == true
+run: |
+  CONFIDENCE=${{ fromJSON(steps.analyze.outputs.structured_output).confidence }}
+```
+
+**In bash with jq:**
+
+```yaml
+- name: Process results
+  run: |
+    OUTPUT='${{ steps.analyze.outputs.structured_output }}'
+    IS_FLAKY=$(echo "$OUTPUT" | jq -r '.is_flaky')
+    SUMMARY=$(echo "$OUTPUT" | jq -r '.summary')
+```
+
+**Note**: Due to GitHub Actions limitations, composite actions cannot expose dynamic outputs. All fields are bundled in the single `structured_output` JSON string.
+
+### Complete Example
+
+See `examples/test-failure-analysis.yml` for a working example that:
+
+- Detects flaky test failures
+- Uses confidence thresholds in conditionals
+- Auto-retries workflows
+- Comments on PRs
+

 ## Ways to Tag @claude
 
 These examples show how to interact with Claude using comments in PRs and issues. By default, Claude will be triggered anytime you mention `@claude`, but you can customize the exact trigger phrase using the `trigger_phrase` input in the workflow.

+
+            Your task:
+            1. Use mcp__github__get_issue to get details of the current issue (#${{ github.event.issue.number }})
+            2. Search for similar existing issues using mcp__github__search_issues with relevant keywords from the issue title and body
+            3. Compare the new issue with existing ones to identify potential duplicates
+
+            Criteria for duplicates:
+            - Same bug or error being reported
+            - Same feature request (even if worded differently)
+            - Same question being asked

+
+            If you find duplicates:
+            - Add a comment on the new issue linking to the original issue(s)
+            - Apply a "duplicate" label to the new issue
+            - Be polite and explain why it's a duplicate
+            - Suggest the user follow the original issue for updates
+
+            If it's NOT a duplicate:
+            - Don't add any comments
+            - You may apply appropriate topic labels based on the issue content
+
+            Use these tools:
+            - mcp__github__get_issue: Get issue details
+            - mcp__github__search_issues: Search for similar issues
+            - mcp__github__list_issues: List recent issues if needed

-
-REVIEW MODE WORKFLOW:
-
-1. First, understand the PR context:
-   - You are reviewing PR #${eventData.isPR && eventData.prNumber ? eventData.prNumber : "[PR number]"} in ${context.repository}
-   - Use the Read, Grep, and Glob tools to examine the modified files directly from disk
-   - This provides the full context and latest state of the code
-   - Look at the changed_files section above to see which files were modified
-
-2. Create review comments using GitHub MCP tools:
-   - Use Bash(gh issue comment:*) for general PR-level comments
-   - Use mcp__github_inline_comment__create_inline_comment for line-specific feedback (strongly preferred)
-   
-3. When creating inline comments with suggestions:
-   CRITICAL: GitHub's suggestion blocks REPLACE the ENTIRE line range you select
-   - For single-line comments: Use 'line' parameter only
-   - For multi-line comments: Use both 'startLine' and 'line' parameters
-   - The 'body' parameter should contain your comment and/or suggestion block
-   
-   How to write code suggestions correctly:
-   a) To remove a line (e.g., removing console.log on line 22):
-      - Set line: 22
-      - Body: ${codeBlock}suggestion
-      ${codeBlock}
-      (Empty suggestion block removes the line)
-   
-   b) To modify a single line (e.g., fixing line 22):
-      - Set line: 22  
-      - Body: ${codeBlock}suggestion
-      await this.emailInput.fill(email);
-      ${codeBlock}
-   
-   c) To replace multiple lines (e.g., lines 21-23):
-      - Set startLine: 21, line: 23
-      - Body must include ALL lines being replaced:
-      ${codeBlock}suggestion
-      async typeEmail(email: string): Promise<void> {
-          await this.emailInput.fill(email);
-      }
-      ${codeBlock}
-   
-   COMMON MISTAKE TO AVOID:
-   Never duplicate code in suggestions. For example, DON'T do this:
-   ${codeBlock}suggestion
-   async typeEmail(email: string): Promise<void> {
-   async typeEmail(email: string): Promise<void> {  // WRONG: Duplicate signature!
-       await this.emailInput.fill(email);
-   }
-   ${codeBlock}
-
-REVIEW GUIDELINES:
-
-- Focus on:
-  * Security vulnerabilities
-  * Bugs and logic errors
-  * Performance issues
-  * Code quality and maintainability
-  * Best practices and standards
-  * Edge cases and error handling
-
-- Provide:
-  * Specific, actionable feedback
-  * Code suggestions using the exact format described above
-  * Clear explanations of issues found
-  * Constructive criticism with solutions
-  * Recognition of good practices
-  * For complex changes: Create separate inline comments for each logical change
-
-- Communication:
-  * All feedback goes through GitHub's review system
-  * Be professional and respectful
-  * Your review body is the main communication channel
-
-Before starting, analyze the PR inside <analysis> tags:
-<analysis>
-- PR title and description
-- Number of files changed and scope
-- Type of changes (feature, bug fix, refactor, etc.)
-- Key areas to focus on
-- Review strategy
-</analysis>
-
-Then proceed with the review workflow described above.
-
-IMPORTANT: Your review body is the primary way users will understand your feedback. Make it comprehensive and well-structured with:
-- Executive summary at the top
-- Detailed findings organized by severity or category
-- Clear action items and recommendations
-- Recognition of good practices
-This ensures users get value from the review even before checking individual inline comments.`;
