# Markdown Viewer with cmux Use this skill to display markdown files in a dedicated panel with rich formatting and live file watching. ## Core Workflow 1. Write your plan or notes to a `.md` file. 2. Open it in a markdown panel. 3. The panel auto-updates when the file changes on disk. ```bash # Open a markdown file as a split panel next to the current terminal cmux markdown open plan.md # Absolute path cmux markdown open /path/to/PLAN.md # Target a specific workspace cmux markdown open design.md --workspace workspace:2 ``` ## When to Use - Displaying an agent plan or task list alongside the terminal - Showing documentation, changelogs, or READMEs while working - Reviewing notes that update in real-time (e.g., a plan file being written by another process) ## Live File Watching The panel automatically re-renders when the file changes on disk. This works with: - Direct writes (`echo "..." >> plan.md`) - Editor saves (vim, nano, VS Code) - Atomic file replacement (write to temp, rename over original) - Agent-generated plan files that are updated progressively If the file is deleted, the panel shows a "file unavailable" state. During atomic replace, the panel attempts automatic reconnection within its short retry window. If the file returns later, close and reopen the panel. ## Agent Integration ### Opening a plan file Write your plan to a file, then open it: ```bash cat > plan.md << 'EOF' # Task Plan ## Steps 1. Analyze the codebase 2. Implement the feature 3. Wr
