What problem does it solve? Viewing plans, documentation, or notes alongside a terminal usually requires switching windows or reading raw markdown text. This Skill renders markdown files in a dedicated cmux panel with rich formatting and automatically re-renders whenever the file changes on disk. ## Core Features & Use Cases - Formatted Markdown Panel: Opens any .md file as a split panel with rendered headings, code blocks, tables, lists, blockquotes, links, and images in light or dark mode. - Live Reload: Watches the file with a kernel-level watcher and re-renders on every write, including atomic editor saves and progressive agent writes. - Flexible Targeting: Supports --workspace, --surface, and --window flags plus JSON output for scripting panel placement. - Use Case: A coding agent writes a plan to plan.md, runs cmux markdown open plan.md, and the user watches the task list update in real time beside the terminal as the agent checks off items. ## Quick Start Write your plan or notes to a markdown file, then ask the agent to run cmux markdown open on that file so it appears in a live-updating panel next to the terminal.
