Claude JSON Config Cleanup

About

This skill provides a specialized maintenance utility for the Claude Code environment by managing the local ~/.claude.json configuration file. As users work on various projects, this file can grow beyond the 25,000 token limit, causing the 'Read' tool to fail with token overflow errors. This skill automates the identification and removal of stale project entries, defunct GitHub paths, and redundant session data, ensuring your configuration remains lightweight while automatically creating safety backups.

Key Features

• Pruning of entries for deleted or non-existent directories
• 1 GitHub stars
• Detailed reporting of file size reduction and token savings
• Automatic backup creation for ~/.claude.json
• Manual analysis tools for deep-diving into config section sizes
• Removal of stale GitHub repository path references

Use Cases

• Resolving 'File content exceeds maximum allowed tokens' errors in Claude Code
• Safely migrating or cleaning up global project metadata without losing MCP settings
• Performing routine maintenance to reduce configuration bloat and improve responsiveness
