Adds support for Claude Code CLI integration, allowing users to use their Claude Max/Pro subscriptions instead of pay-per-token API pricing. This provides cost predictability for heavy Claude users with a fixed monthly cost. The feature includes new commands for setup/testing and automatically switches between gateway and subscription modes.

Key changes:

• New Claude Code configuration section in config.yaml
• CLI commands for authentication and testing (infer claude-code setup/test)
• ClaudeCodeClient adapter that wraps the official Claude CLI
• Static model service for Claude subscription models
• Updated documentation with cost comparison and setup instructions

Files changed:

• .infer/config.yaml - Added Claude Code configuration section
• README.md - Updated with Claude Code documentation
• cmd/agent.go - Added Claude Code command integration
• cmd/claude_code.go - New Claude Code CLI commands
• cmd/config.go - Updated configuration handling
• cmd/root.go - Added Claude Code command to root
• cmd/status.go - Updated status display
• config/config.go - Added Claude Code config structs
• internal/agent/agent_streaming.go - Updated agent streaming
• internal/agent/agent_utils.go - Updated agent utilities
• internal/agent/tools/todowrite.go - Updated tool handling
• internal/app/chat.go - Updated chat application
• internal/container/container.go - Updated dependency injection
• internal/infra/adapters/claude_code_client.go - New Claude Code client adapter
• internal/services/model_claude_code.go - New Claude Code model service
• internal/ui/components/conversation_view.go - Updated UI components
• internal/ui/components/model_selection_view.go - Updated model selection

Benefits:

1. Cost predictability - Fixed monthly cost instead of variable API usage
2. Automatic switching - Seamlessly switches between gateway and subscription modes
3. Easy setup - Simple CLI commands for authentication and testing
4. Full integration - Works with all existing features and UI components

Testing:

• Run infer claude-code setup to authenticate with Claude CLI
• Run infer claude-code test to verify connectivity
• Models will automatically appear in model selection when configured

NOT RECOMMENDED

It's essentially infer -> claude-code -> response - essentially invoking claude-code in non-interactive mode and displaying the results in the infer chat - that means you need claude-code installed + probably the javascript runtime.
Better approach would be to use anthropics API by setting ANTHROPIC_API_KEY - then we only use the inference and we can use any tools from the tool box - it's more expensive because of pay-as-you-go model but it provides faster results.
