HIC Mouse gives your AI coding assistant surgical precision for file editing. Instead of rewriting entire files, your AI uses Mouse's tools to make targeted, line-level changes — faster, safer, and more accurate.
Works with: GitHub Copilot, Claude Code, Amazon Q Developer, Roo Code, Kilo Code, and other MCP-compatible AI coding assistants in VS Code, Cursor, and Kiro.
