Claude Code GitHub Action v1.0

🎉 Claude Code GitHub Action v1.0 - Now Generally Available!

We're excited to announce the v1.0 release of Claude Code GitHub Action! This major release brings significant improvements in simplicity, flexibility, and power to AI-assisted development workflows.

🚀 What's New in v1.0

Simplified Configuration

• Automatic mode detection - No more manual mode configuration. The action intelligently determines whether to run in interactive or automation mode based on your setup
• Unified interface - All prompts now go through a single prompt input, and all CLI options through claude_args
• Better SDK alignment - Closer integration with the Claude Code CLI for a consistent experience

More Powerful & Flexible

• Direct access to all Claude Code CLI capabilities through claude_args
• Support for custom system prompts, tool configurations, and model selection
• Enhanced compatibility with AWS Bedrock and Google Vertex AI

⚠️ Breaking Changes

This release includes breaking changes from v0.x. Key deprecated inputs have been replaced with a cleaner, more intuitive API:

• mode, direct_prompt, override_prompt → unified prompt input
• custom_instructions, model, allowed_tools, mcp_config → claude_args with CLI format
• Other deprecated: disallowed_tools, anthropic_model, trigger_phrase, timeout_minutes

📚 Please review our Migration Guide for detailed upgrade instructions and examples.

💡 New Use Cases & Examples

Explore the expanded possibilities with v1.0! We've created comprehensive examples showcasing various workflows:

• Automated PR Reviews - Intelligent code review on every pull request
• CI Failure Fixes - Automatically diagnose and fix failing tests
• Issue Triage - Smart categorization and response to new issues
• Documentation Generation - Keep docs in sync with code changes
• Security Scanning - Proactive vulnerability detection
• And many more!
