 # 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 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, 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 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.
 
 ## 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

 - 🛠️ **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
 - 🏃 **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** ⚠️
 
-**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.
+**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

+### Tag Mode (Default)
 
-Activated when Claude detects @mentions, issue assignments, or labels—without an explicit `prompt`.

-    # Automatically runs in agent mode when prompt is provided
 ```
 
-### How It Works
+### Experimental Review Mode
 
-The action uses this logic to determine the mode:
+**Warning: This is an experimental feature that may change or be removed at any time.**
 
-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
+For automated code reviews on pull requests.

 ## Configuration and Tools
 
-### How does automatic mode detection work?
+### What's the difference between `direct_prompt` and `custom_instructions`?
 
-The action intelligently detects whether to run in interactive mode or automation mode:
+These inputs serve different purposes in how Claude responds:
 
-- **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
+- **`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").
 
-This automatic detection eliminates the need to manually configure modes.
+- **`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 ...".
 
 Example:
 
 ```yaml
-# Automation mode - runs automatically
-prompt: "Review this PR for security vulnerabilities"
-# Interactive mode - waits for @claude mention
-# (no prompt provided)

-## 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

-  --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"`  |

-- [ ] Update action version from `@beta` to `@v1`
-- [ ] Remove `mode` input (auto-detected now)
-- [ ] Replace `direct_prompt` with `prompt`
-- [ ] Replace `override_prompt` with `prompt` using GitHub context
-- [ ] Move `custom_instructions` to `claude_args` with `--system-prompt`
-- [ ] Convert `max_turns` to `claude_args` with `--max-turns`
-- [ ] Convert `model` to `claude_args` with `--model`
-- [ ] Convert `allowed_tools` to `claude_args` with `--allowedTools`
-- [ ] Convert `disallowed_tools` to `claude_args` with `--disallowedTools`
-- [ ] Move `claude_env` to `settings` JSON format
-- [ ] Move `mcp_config` to `claude_args` with `--mcp-config`
-- [ ] Test workflow in a non-production environment

-# Fix CI Failures with Signed Commits
-
-You are tasked with analyzing CI failure logs and fixing the issues using MCP tools for signed commits. Follow these steps:
-
-## Context Provided
-
-$ARGUMENTS
-
-## Important Context Information
-
-Look for these key pieces of information in the arguments:
-
-- **Failed CI Run URL**: Link to the failed CI run
-- **Failed Jobs**: List of jobs that failed
-- **PR Number**: The PR number to comment on
-- **Branch Name**: The fix branch you're working on
-- **Base Branch**: The original PR branch
-- **Error logs**: Detailed logs from failed jobs
-
-## CRITICAL: Use MCP Tools for Git Operations
-
-**IMPORTANT**: You MUST use MCP tools for all git operations to ensure commits are properly signed. DO NOT use `git` commands directly via Bash.
-
-- Use `mcp__github_file_ops__commit_files` to commit and push changes
-- Use `mcp__github_file_ops__delete_files` to delete files
-
-## Step 1: Analyze the Failure
-
-Parse the provided CI failure information to understand:
-
-- Which jobs failed and why
-- The specific error messages and stack traces
-- Whether failures are test-related, build-related, or linting issues
-
-## Step 2: Search and Understand the Codebase
-
-Use MCP search tools to locate the failing code:
-
-- Use `mcp_github_file_ops_server__search_files` or `mcp_github_file_ops_server__file_search` to find failing test names or functions
-- Use `mcp_github_file_ops_server__read_file` to read source files mentioned in error messages
-- Review related configuration files (package.json, tsconfig.json, etc.)
-
-## Step 3: Apply Targeted Fixes
-
-Make minimal, focused changes:
-
-- **For test failures**: Determine if the test or implementation needs fixing
-- **For type errors**: Fix type definitions or correct the code logic
-- **For linting issues**: Apply formatting using the project's tools
-- **For build errors**: Resolve dependency or configuration issues
-- **For missing imports**: Add the necessary imports or install packages
-
-Requirements:
-
-- Only fix the actual CI failures, avoid unrelated changes
-- Follow existing code patterns and conventions
-- Ensure changes are production-ready, not temporary hacks
-- Preserve existing functionality while fixing issues
-
-## Step 4: Verify Fixes Locally
-
-Run available verification commands using Bash:
-
-- Execute the failing tests locally to confirm they pass
-- Run the project's lint command (check package.json for scripts)
-- Run type checking if available
-- Execute any build commands to ensure compilation succeeds
-
-## Step 5: Commit and Push Changes Using MCP
-
-**CRITICAL**: You MUST use MCP tools for committing and pushing:
-
-1. Prepare all your file changes (using Edit/MultiEdit/Write tools as needed)
-2. **Use `mcp__github_file_ops__commit_files` to commit and push all changes**
-   - Pass the file paths you've edited in the `files` array
-   - Set `message` to describe the specific fixes (e.g., "Fix CI failures: remove syntax errors and format code")
-   - The MCP tool will automatically create the branch specified in "Branch Name:" from the context and push signed commits
-
-**IMPORTANT**: The MCP tool will create the branch from the context automatically. The branch name from "Branch Name:" in the context will be used.
-
-Example usage:
-
-```
-mcp__github_file_ops__commit_files with:
-- files: ["src/utils/retry.ts", "src/other/file.ts"]  // List of file paths you edited
-- message: "Fix CI failures: [describe specific fixes]"
-```
-
-Note: The branch will be created from the Base Branch specified in the context.
-
-## Step 6: Create PR Comment (REQUIRED - DO NOT SKIP)
-
-**CRITICAL: You MUST create a PR comment after pushing. This step is MANDATORY.**
-
-After successfully pushing the fixes, you MUST create a comment on the original PR to notify about the auto-fix. DO NOT end the task without completing this step.
-
-1. Extract the PR number from the context provided in arguments (look for "PR Number:" in the context)
-2. **MANDATORY**: Execute the gh CLI command below to create the comment
-3. Verify the comment was created successfully
-
-**YOU MUST RUN THIS COMMAND** (replace placeholders with actual values from context):
-
-```bash
-gh pr comment PR_NUMBER --body "## 🤖 CI Auto-Fix Available (Signed Commits)
-
-Claude has analyzed the CI failures and prepared fixes with signed commits.
-
-[**→ Create pull request to fix CI**](https://github.com/OWNER/REPO/compare/BASE_BRANCH...FIX_BRANCH?quick_pull=1)
-
-_This fix was generated automatically based on the [failed CI run](FAILED_CI_RUN_URL)._"
-```
-
-**IMPORTANT REPLACEMENTS YOU MUST MAKE:**
-
-- Replace `PR_NUMBER` with the actual PR number from "PR Number:" in context
-- Replace `OWNER/REPO` with the repository from "Repository:" in context
-- Replace `BASE_BRANCH` with the branch from "Base Branch:" in context
-- Replace `FIX_BRANCH` with the branch from "Branch Name:" in context
-- Replace `FAILED_CI_RUN_URL` with the URL from "Failed CI Run:" in context
-
-**DO NOT SKIP THIS STEP. The task is NOT complete until the PR comment is created.**
-
-## Step 7: Final Verification
-
-**BEFORE CONSIDERING THE TASK COMPLETE**, verify you have:
-
-1. ✅ Fixed all CI failures
-2. ✅ Committed the changes using `mcp_github_file_ops_server__push_files`
-3. ✅ Verified the branch was pushed successfully
-4. ✅ **CREATED THE PR COMMENT using `gh pr comment` command from Step 6**
-
-If you have NOT created the PR comment, go back to Step 6 and execute the command.
-
-## Important Guidelines
-
-- Always use MCP tools for git operations to ensure proper commit signing
-- Focus exclusively on fixing the reported CI failures
-- Maintain code quality and follow the project's established patterns
-- If a fix requires significant refactoring, document why it's necessary
-- When multiple solutions exist, choose the simplest one that maintains code quality
-- **THE TASK IS NOT COMPLETE WITHOUT THE PR COMMENT**
-
-Begin by analyzing the failure details provided above.

-            Repository: ${{ github.repository }}
-
-            Your task:
-            1. Use mcp__github__get_issue to get details of the current issue (#${{ 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
-            - Issues describing the same root problem
-
-            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
-            - mcp__github__create_issue_comment: Add a comment if duplicate found
-            - mcp__github__update_issue: Add labels
-
-            Be thorough but efficient. Focus on finding true duplicates, not just similar issues.

-            You're an issue triage assistant for GitHub issues. Your task is to analyze the issue and select appropriate labels from the provided list.
-
-            IMPORTANT: Don't post any comments or messages to the issue. Your only action should be to apply labels.
-
-            Issue Information:
-            - REPO: ${{ github.repository }}
-            - ISSUE_NUMBER: ${{ github.event.issue.number }}
-
-            TASK OVERVIEW:
-
-            1. First, fetch the list of labels available in this repository by running: `gh label list`. Run exactly this command with nothing else.
-
-            2. Next, use the GitHub tools to get context about the issue:
-               - You have access to these tools:
-                 - mcp__github__get_issue: Use this to retrieve the current issue's details including title, description, and existing labels
-                 - mcp__github__get_issue_comments: Use this to read any discussion or additional context provided in the comments
-                 - mcp__github__update_issue: Use this to apply labels to the issue (do not use this for commenting)
-                 - mcp__github__search_issues: Use this to find similar issues that might provide context for proper categorization and to identify potential duplicate issues
-                 - mcp__github__list_issues: Use this to understand patterns in how other issues are labeled
-               - Start by using mcp__github__get_issue to get the issue details
-
-            3. Analyze the issue content, considering:
-               - The issue title and description
-               - The type of issue (bug report, feature request, question, etc.)
-               - Technical areas mentioned
-               - Severity or priority indicators
-               - User impact
-               - Components affected
-
-            4. Select appropriate labels from the available labels list provided above:
-               - Choose labels that accurately reflect the issue's nature
-               - Be specific but comprehensive
-               - 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

+
+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.`;
