Is this skill compatible with Linux or Windows?

This specific skill is optimized for macOS because it utilizes AppleScript to automate iTerm2 window creation. Linux users should run the asciinema play command directly.

What dependencies are required to use this skill?

The skill requires iTerm2 and the asciinema CLI tool. It includes a preflight check to help you install these via Homebrew if they are missing.

Can I control the recording while it is playing?

Yes, once the iTerm2 window opens, you can use standard keyboard shortcuts: Space to pause/resume, '.' to step frame-by-frame, and Ctrl+C to exit.

Why use iTerm2 instead of a browser-based player?

Web players often crash or consume excessive memory (2-4GB) when handling large .cast files. The iTerm2 CLI method streams from disk, ensuring instant startup and minimal resource usage.

Developer Tools

Plays and manages asciinema terminal recordings in a dedicated iTerm2 window with advanced playback controls.

About

This skill streamlines the playback of .cast terminal recordings by launching them in a clean, native iTerm2 window on macOS. It bypasses the limitations of browser-based players—such as memory crashes and lag with large files—and provides a professional CLI interface for controlling speed, idle time, and looping. Ideal for reviewing long DevOps sessions, debugging CLI workflows, or presenting terminal-based tutorials without taxing system resources.

Key Features

Native iTerm2 playback via automated AppleScript window management
Optimized streaming for large recording files exceeding 100MB
Configurable playback speeds ranging from 2x to 16x or custom multipliers
Smart dependency verification and automated installation for iTerm2 and asciinema
8 GitHub stars
Interactive options including idle-time capping, looping, and terminal resizing

Use Cases

Reviewing complex DevOps automation logs and long terminal sessions efficiently
Demonstrating CLI workflows and tutorials during live presentations or code reviews
Auditing terminal-based security sessions or deployment recordings
