HyperFrames CLI Skill for Checking and Previewing Video in Codex
Scaffold a local HTML video, read its timeline and clips, and check rendering issues through the HyperFrames CLI.
中文Setup for Codex
Requires Node.js 22 or later and FFmpeg. Preview and validation need a Chromium runtime available to HyperFrames.
- Run `npx hyperframes skills update` in the project, and select Codex and the core skills if the picker appears. This pairs the skill set with the installed CLI release.
- Open the project in Codex and select $hyperframes-cli. Keep the full skill directory and sibling hyperframes references if copying the pinned files into .agents/skills.
Example task
Use $hyperframes-cli in an empty workspace to scaffold a project with `npx hyperframes init launch-test --skip-skills`. From launch-test, run `npx hyperframes timeline --json` and `npx hyperframes check --json`. Report the returned compositions and any failures.Expected result
The timeline yields machine-readable project data. The check reports validation status and any issue with the generated project or rendering environment.

Frequently asked question
How do I inspect a video timeline using the HyperFrames CLI skill in Codex?
Load the skill in a HyperFrames project. Start with timeline JSON to identify compositions and clip tracks, then run the check command before rendering.
