The Agent Skills Directory

[Local Command Execution]: The skill utilizes subprocess to execute internal scripts and external tools like ffmpeg. These calls are used to process media assets, compose section clips, and manage the artifact build pipeline within the local environment.
[Resource Acquisition]: The assembly script fetches the MathJax library from the npm registry (registry.npmjs.org) to provide LaTeX rendering support in the generated HTML viewer. This download is intended to ensure the viewer remains functional for mathematical content in offline or self-contained environments.
[Verification Gate]: A quality assurance script employs browser automation to validate the final output against a predefined functional contract. This process ensures that navigation, keyboard shortcuts, and media interactions work correctly before the task is considered complete.
[Local Preview Server]: The skill includes a server script designed to support HTTP Range requests. This is a technical requirement for HTML5 video seeking, allowing the agent or user to verify that the generated interactive timeline functions correctly.
