+
+**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)**

 ## Quickstart
 
 The easiest way to set up this action is through [Claude Code](https://claude.ai/code) in the terminal. Just open `claude` and run `/install-github-app`.

-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 mcp__github__get_pull_request to get PR metadata
-   - 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 a pending review:
-   - Use mcp__github__create_pending_pull_request_review to start your review
-   - This allows you to batch comments before submitting
-
-3. Add inline comments:
-   - Use mcp__github__add_comment_to_pending_review for each issue or suggestion
-   - Parameters:
-     * path: The file path (e.g., "src/index.js")
-     * line: Line number for single-line comments
-     * startLine & line: For multi-line comments (startLine is the first line, line is the last)
-     * side: "LEFT" (old code) or "RIGHT" (new code)
-     * subjectType: "line" for line-level comments
-     * body: Your comment text
-   
-   - When to use multi-line comments:
-     * When replacing multiple consecutive lines
-     * When the fix requires changes across several lines
-     * Example: To replace lines 19-20, use startLine: 19, line: 20
-   
-   - For code suggestions, use this EXACT format in the body:
-     \`\`\`suggestion
-     corrected code here
-     \`\`\`
-   
-   CRITICAL: GitHub suggestion blocks must ONLY contain the replacement for the specific line(s) being commented on:
-   - For single-line comments: Replace ONLY that line
-   - For multi-line comments: Replace ONLY the lines in the range
-   - Do NOT include surrounding context or function signatures
-   - Do NOT suggest changes that span beyond the commented lines
-   
-   Example for line 19 \`var name = user.name;\`:
-   WRONG:
-   \\\`\\\`\\\`suggestion
-   function processUser(user) {
-       if (!user) throw new Error('Invalid user');
-       const name = user.name;
-   \\\`\\\`\\\`
-   
-   CORRECT:
-   \\\`\\\`\\\`suggestion
-   const name = user.name;
-   \\\`\\\`\\\`
-   
-   For validation suggestions, comment on the function declaration line or create separate comments for each concern.

-4. Submit your review:
-   - Use mcp__github__submit_pending_pull_request_review
-   - Parameters:
-     * event: "COMMENT" (general feedback), "REQUEST_CHANGES" (issues found), or "APPROVE" (if appropriate)
-     * body: Write a comprehensive review summary that includes:
-       - Overview of what was reviewed (files, scope, focus areas)
-       - Summary of all issues found (with counts by severity if applicable)
-       - Key recommendations and action items
-       - Highlights of good practices observed
-       - Overall assessment and recommendation
-   - The body should be detailed and informative since it's the main review content
-   - Structure the body with clear sections using markdown headers
-
-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 when possible (following GitHub's format exactly)
-  * Clear explanations of issues
-  * Constructive criticism
-  * Recognition of good practices
-  * For complex changes that require multiple modifications:
-    - Create separate comments for each logical change
-    - Or explain the full solution in text without a suggestion block
-
-- 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.`;
