Chat History Extractor

Extract user inputs from Claude Code session history (~/.claude/projects/) and organize them into a project's .chats directory with daily markdown files.

When to Use This Skill

Use this skill when the user wants to:

• Extract session history from Claude Code sessions
• Document conversations for future reference
• Create instruction logs organized by date
• Export user inputs from .jsonl session files
• Maintain a changelog of Claude interactions

How It Works

Claude Code stores session data in ~/.claude/projects/{project-path-encoded}/ as .jsonl files. Each file contains messages with:

• type: "user" - User messages
• userType: "external" - External user (not system/agent)
• message.content - The actual message content
