A workflow for turning CSV or JSON data into editable, deterministic data-visualization videos. It uses chart templates and HyperFrames, a composition and rendering system, to prepare, preview, validate, and render the result.

Use it to make line-chart stories, ranking videos, and similar visual explanations from local data or an approved public data source.

It avoids creating a separate animation and video-rendering system for every chart story. It also requires the supporting HyperFrames skill, so the workflow stops rather than pretending it can work without that dependency.

About the project

AI Animation Skills is a collection of agent instructions and templates for generating single-file HTML animations, including presentations, diagrams, protocol visualizations, phone interfaces, and video-style scenes. People use the skills with AI coding agents to create animated web pages from descriptions or templates. The catalogue entries are the collection's individual generation workflows.

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.

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	$0.00100	$0.02179
Opus 5.5	$0.00040	$0.00872
Sonnet 5.5	$0.00020	$0.00436
Haiku 4.5	$0.00010	$0.00218

Security

Grade A, and why

plotbeat 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 16d ago.

The scan reads SKILL.md. This mod also ships 10 executable files (analytics.ts, build-catalog.mjs, chatgpt-auth.ts, …), 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.

How it starts

The opening of the file, as written. The whole thing — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plotbeat

Turn user-supplied data into a local HyperFrames composition. Start from a proven template, compile the data before playback, then use HyperFrames for timing, preview, validation, and rendering.

Require HyperFrames

Treat this as a fail-closed dependency gate. Before acquiring data, listing templates, scaffolding, editing, previewing, validating, or rendering:

Resolve and read the installed hyperframes AI skill.
If it is unavailable, stop and ask the user to install it with:
```
npx skills add heygen-com/hyperframes --all
```
Do not approximate the missing skill from general knowledge, use Plotbeat as a standalone generator, or continue with only the HyperFrames npm CLI.
After the dependency is installed, resume through the hyperframes skill, then use Plotbeat for the data-video template workflow.

Preserve the product boundary

Treat HyperFrames as the composition and rendering engine.
Start through the main hyperframes skill and load its hyperframes-core, hyperframes-animation, and hyperframes-cli guidance as required.
Do not add a competing render loop, video encoder, scene scheduler, or standalone animation runtime.
Keep the output editable as an ordinary HyperFrames HTML project.
Use one paused, seek-safe timeline per scene. Derive visual state from timeline progress.
Keep the bundled music as a separate local <audio> element. Let HyperFrames own playback and use the registered GSAP timeline for volume fades; never call play(), pause(), or set currentTime yourself.
The bundled master covers the quick, standard, and deliberate presets (up to 56 seconds). For a longer exact duration, resolve or ingest a longer local BGM asset before previewing.
Compile CSV or JSON into a frozen local generated/data.js. Do not fetch live data during playback.
Do not use requestAnimationFrame, timers, D3 transitions, or nondeterministic randomness as playback clocks.

Acquire the dataset

Accept either a local .csv/.json file or a request to retrieve data from a named source, URL, public API, or authorized connector.
When retrieval is requested, fetch during preparation with the available connector, browser, API, or CLI. Do not make the user manually download a file when the agent can obtain it safely.
Prefer first-party and authoritative sources. Clarify the metric, entities or geography, date range, and frequency only when ambiguity would materially change the story.
Save the retrieved rows locally as CSV or JSON before scaffolding. Preserve the source URL or API name, query or filters, retrieval date, and material transformations; pass a concise citation through --source.
Never invent missing observations or silently join incompatible series. State any interpolation, aggregation, filtering, or carry-forward policy.
Fetch authenticated or private data only through access the user has authorized. Never expose credentials in the composition.

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.

plotbeat is a skill published in the GitHub repository Unclecheng-li/AI_Animation (1,596 stars, last pushed 2d ago), licensed MIT. It adds 100 tokens to every session and 2,179 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-06.
