Feature Request: Terminal Attachment for Real-time Claude Code Session Monitoring

Summary

Add ability to attach a terminal to observe Claude Code's thinking process, tool usage, and file modifications in real-time during active sessions.

Description

Currently, when Claude Code is working on tasks, users have limited visibility into the ongoing process. This feature would allow users to attach a separate terminal window to watch Claude Code's reasoning, tool invocations, and file changes as they happen.

Proposed Implementation

Command Structure:

# Attach to latest session (shows all activity)
claude code attach

# Filter specific activity types
claude code attach --only thinking
claude code attach --only tools
claude code attach --only writes

Filter Options:

• thinking - Display Claude's reasoning and decision-making process
• tools - Show tool invocations (file reads, searches, command executions)
• writes - Display file modifications and creations in real-time

Benefits

1. Transparency - Users can observe Claude Code's problem-solving approach
2. Educational Value - Developers can learn from Claude's reasoning patterns
3. Debugging - Easier to understand why certain decisions were made
4. Engagement - Provides interesting real-time feedback during longer tasks
5. Trust Building - Seeing the process builds confidence in the output

Use Cases

• Monitoring progress on complex refactoring tasks
• Learning how Claude approaches different coding challenges
• Debugging unexpected outcomes by reviewing the decision process
• Educational demonstrations of AI-assisted development

Technical Considerations

• Should support multiple attached terminals
• Minimal performance impact on the main Claude Code process
• Clear formatting to distinguish between thinking/tools/writes
• Option to save session logs for later review

Additional Enhancement Ideas

• Color coding for different activity types
• Timestamps for each action
• Ability to pause/resume the stream
• Search functionality within the attached session output

This feature would significantly enhance the Claude Code experience by providing transparency and insight into the AI's development process.
