A workspace for producing a music video from an existing MP3. The video uses visual storyboard shots played over the song, with no voiceover, dialogue or on-screen lyrics.

Use it to write a visual concept, define characters, build a storyboard and prepare the visual video sequence for an uploaded song.

It gives a song a planned visual sequence instead of leaving the video concept and shot order undefined. Characters, references and shots can be organized in one place.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

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.

Model	Per session	Once invoked
Fable 5.1	$0.00149	$0.02715
Opus 5	$0.00075	$0.01358
Sonnet 5	$0.00030	$0.00543
Haiku 4.5	$0.00015	$0.00271

Measured 12d ago against content hash 9dfb76a84b0c, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade A, and why

kelly-mv 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 21 executable files (content/kelly-mv-app/app/accent-theme.js, content/kelly-mv-app/app/app.js, content/kelly-mv-app/app/demo-visuals.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.

Kelly MV

App UI Screenshots

Core Idea

Use this skill as a music-video creative workspace. The app is the human editing surface; the skill is the creative producer: it reasons, drafts, validates, exports, and fulfills the AI-generation requests the app can only queue. The app reads and writes a Busabase workspace — one Folder, four Bases (project/settings/cast/shots) — plus Busabase Drive Assets for every uploaded or generated MP3/image/video.

An MV here is pure picture — no voiceover, no dialogue, no on-screen lyrics. The job is simple: take an existing MP3 and give it visuals. The final video is the storyboard shots played in order over the song. (For voiced/dialogue drama, use kelly-drama instead — that is its job.)

The app has exactly four areas: 概括 (Concept), Song, 角色 (Cast), 分镜 (Storyboard). Keep it that simple — don't reintroduce song sections, timeline tiling, or large per-shot production sheets.

Default to the AirApp for ongoing creative work — give the user the clickable AirApp URL, or run pnpm --dir content/kelly-mv-app dev for a local preview. Use chat-only mode only when the user explicitly asks for "chat only", "no UI", "纯聊天", or similar.

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.
