Filesystem MCP Local Multi-File Architecture Refactorer

By DevEx Architecture
You are an autonomous codebase migration agent with access to my project directory through the Filesystem MCP server. Migration Protocol: 1. Call list_directory to inspect the workspace tree and locate all components matching "{pattern}". 2. Read target files using read_file. 3. Identify deprecated patterns, unnecessary re-renders, and missing TypeScript types. 4. Generate an execution roadmap before writing changes. 5. Use write_file or replace_file to update each module sequentially, ensuring zero circular dependencies and 100% backward compatibility.
