Claude Code Action

Overview

Claude Code Action is a GitHub Action designed to bring Claude Code's developer-facing capabilities directly into GitHub workflows (pull requests, issues, and automation). It can answer code questions, run code reviews, suggest improvements, and implement simple fixes or feature additions automatically or via interactive prompts. The action emphasizes configurable execution modes, privacy (runs on your runners), and multi-provider authentication.

Key features

• Intelligent mode detection: automatically chooses the correct execution mode based on workflow context (mentions, assignments, explicit prompts).
• Interactive code assistant: respond to developer comments, explain code, and provide suggestions in PR and issue threads.
• Code review & implementation: analyze diffs, propose improvements, and implement small code changes or refactors when authorized.
• Flexible provider support: supports direct Anthropic API and major cloud LLM providers (AWS Bedrock, Google Vertex AI, Microsoft Foundry), letting organizations choose infrastructure.
• Runs on your infrastructure: executes on the repository's GitHub runner so network/data access and provider calls occur under your control.
• Structured outputs & automation: emits validated JSON outputs to be used by subsequent workflow steps; includes visual progress checkboxes that update as tasks complete.
• Simplified configuration: unified inputs (prompt, claude_args) with migration guidance from v0.x to v1.0.

Installation & quickstart

The repository provides a quickstart that installs a GitHub app and sets required secrets. For direct Anthropic API users there is an interactive terminal installer; cloud-provider-specific setup guides (AWS, Google, Microsoft) are available in the docs. Repository README and docs/ directories include examples and solution patterns for common automation tasks.

Authentication & providers

The action supports multiple authentication methods so teams can route model calls through their chosen provider. Documentation covers how to configure provider-specific secrets and IAM/permissions for Bedrock, Vertex AI, and Foundry, as well as direct Anthropic API usage.

Typical use cases

• Automated PR code review and suggestions
• Path-specific or scheduled repository health checks
• External contributor handling and triage automation
• Automated documentation sync and security-focused reviews
• Creating progress-tracking comments and structured outputs for downstream automation

Security, limits & best practices

• Runs on your runner to limit data exposure; repository admins must install the GitHub app and add required secrets.
• Docs include a security section covering permissions, commit signing, and network restrictions. The README also outlines capabilities and limitations so teams understand when to trust automated changes.

Documentation & resources

Full documentation is included in the repo (setup, usage, solutions, migration guide, experimental features, cloud provider guides, FAQ). The project is MIT-licensed.
