SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Editing files inside Claude's workspace can be cumbersome when context switching and editors are split across surfaces. This skill opens a file in an adjacent cmux editor surface and provides a live viewer pane for file types with a configured viewer, enabling faster in-context edits.

Core Features & Use Cases

  • Open an editor in a new cmux surface adjacent to Claude for focused file editing.
  • If the file type has an explicit viewer, automatically open a live viewer pane beside the editor for instant feedback.
  • Resolve the target file and editor from user input and conversation history, supporting optional editor overrides.
  • Manage surface splits to place editor and viewer side-by-side, preserving workflow continuity in interactive sessions.

Quick Start

Edit a file by typing /ed:edit path/to/file.txt to launch an editor adjacent to Claude with an optional viewer.
