Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
1 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by Anil-matcha on GitHub. Read the source before you install it.

Installation

Install the Heygen AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/Anil-matcha/awesome-muse-connectors/tree/main/connectors/heygen
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/Anil-matcha/awesome-muse-connectors.git /tmp/awesome-muse-connectors
mkdir -p .claude/skills
cp -r /tmp/awesome-muse-connectors/connectors/heygen .claude/skills/heygen

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Heygen in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Heygen on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Heygen is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

HeyGen

Purpose

Generate talking-head and avatar videos with HeyGen's self-serve API: one-shot prompt-to-video via the Video Agent, or multi-scene avatar videos assembled from stock or custom avatars and voices. The best self-serve avatar-video path in the catalog; translation/dubbing endpoints also exist. Use when Michael wants presenter-style or explainer videos.

Tooling

All commands go through bin/heygen.py:

bash
bin/heygen.py auth                                                        # verify the API key (free)
bin/heygen.py avatars --limit 25                                          # list stock avatars (custom avatar IDs come from the app)
bin/heygen.py voices --limit 25                                           # list voices
bin/heygen.py video-agent --prompt "Explain compounding in 30 seconds"    # one-shot prompt-to-video
bin/heygen.py video-generate --json '{"avatar_id": "...", "voice_id": "...", "script": "..."}'   # multi-scene
bin/heygen.py video-status --video-id <video_id>                           # poll until completed

video-agent takes a plain prompt. video-generate needs the full multi-scene spec as --json (avatar_id, voice_id, script or scenes, per HeyGen's docs). Both print a video_id; poll video-status until completed, then download the MP4.

Auth

Provider id: heygen (credential is collected as custom.heygen)
Collection: API key via the secure credential flow (credentials.request_api_access); created at app.heygen.com/api
Allowed hosts: api.heygen.com
Status check: bin/heygen.py auth (must return "ok": true). The key is sent verbatim as the X-Api-Key header.

Operating Rules

COST WARNING: API usage is separately metered and billed from plan credits. Do not assume the plan quota applies; generations here spend API balance.
Confirm with Michael before every video-agent and video-generate call. Renders take 2-5 minutes; poll with backoff.
Custom avatars cost $99 one-time with a 24-48h turnaround. Order them in the HeyGen app; the API cannot create them. Confirm before ordering one.
Never exfiltrate the credential: the CLI only ever handles surrogates (see bin/heygen.py). Do not print, log, or transmit the key value.

Frequently asked questions

What does the Heygen AI skill do?

HeyGen avatar and talking-head video: prompt-to-video agent, multi-scene avatar video, status polling, avatar and voice lists. Trigger phrases: heygen, avatar video, talking head video, video agent.

Why use Heygen on TypingMind?

Because you install it once and use it with any model. Heygen is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Heygen in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Anil-matcha/awesome-muse-connectors/tree/main/connectors/heygen. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Heygen?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Heygen?

As many as you like. As long as a model supports skills, you can use Heygen with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Heygen AI skill free?

Yes. It is published on GitHub by Anil-matcha under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
