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
