.agents/skills/music-to-video/SKILL.md

music-to-video is a skill for Claude Code, Codex from LinHao-city/StoryMind. It costs 143 tokens per session (3,872 once invoked), scanned A, original, AGPL-3.0.

A workflow for making HyperFrames videos whose visual frames change in time with a music track.

In plain words
What is it for?
Use it when an audio file, or audio extracted from a video, should drive a beat-synced video with planned frames and typography.
Why use it?
It removes the need to manually match every visual change to the music's beat and intensity.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is LinHao-city/StoryMind's own configuration. It tells Claude Code and Codex how to work on StoryMind itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything StoryMind configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

music-to-video scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (references/motion-primitives/assets/gsap.min.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
