HyperFrames
Open-source framework that lets coding agents turn HTML, CSS, media and seekable animations into deterministic MP4 videos.
🛡️ AgentReady threat assessment
MAESTRO 7-layer threat model + OWASP AIVSS risk score for HyperFrames, derived from its capabilities.
These scores are auto-generated from public information (the agent's own listing, docs, and repository) using the canonical OWASP AIVSS formula and the MAESTRO framework — an estimate for guidance, not a penetration test, audit, or certification.

Overview
HyperFrames is an Apache-2.0 open-source framework from heygen-com for creating deterministic MP4 videos from HTML, CSS, media assets and seekable animations. It can be used locally with its CLI, by AI coding agents through installable skills, or as the rendering core behind hosted authoring workflows. The official GitHub README describes an agent-oriented production loop where agents plan a video, write valid HTML, wire seekable animations, add media, lint, preview and render. The skills are described as working with Claude Code, Cursor, Gemini CLI, Codex and other coding agents that support skills.
