What it does
Heygen is an agent skill from zapier/connectors, published by the product's own GitHub organization. Agent-callable HeyGen tools — generate AI avatar videos, translate and lip-sync videos, synthesize speech, and clone or browse voices and avatars. Use when the user mentions HeyGen or wants to create, translate, or check the status of AI videos, or to generate or clone a voice — including requests that don't name HeyGen, e.g. make an avatar video from a script, translate a video to Spanish, turn a script into a voiceover, or clone a voice from a recording.
Its SKILL.md is about 4.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 83 other files, including scripts and reference files (for example `.claude-plugin/plugin.json`, `.mcp.json` and `CHANGELOG.md`). Compatibility notes: Run npm install --omit=dev in this directory, then node cli.js. The TypeScript source needs Node.js 22.18+; on older Node, run cli.js for build-it-yourself /…
It sits in Media & Creative, covering AI video generation and Text to speech and voice. It works with HeyGen and Zapier. The repository describes itself as: Connect your agent to the apps you already use - with or without Zapier.
When your agent uses it
- The user mentions HeyGen
- Wants to create
- Check the status of AI videos
- Clone a voice — including requests that dont name HeyGen
Example prompts
- “/heygen”
Requirements
- Node.js
- Compatibility (from SKILL.md): Run `npm install --omit=dev` in this directory, then `node cli.js`. The TypeScript source needs Node.js 22.18+; on older Node, run `cli.js` for build-it-yourself / prebuilt / alternative-runtime options.
What it can do on your machine
Read from SKILL.md and the folder at commit e48d26f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (TypeScript and JavaScript, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
npmnpxgit
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
api.heygen.com
Also links to:
developers.heygen.comagentskills.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
HEYGEN_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Run `npm install --omit=dev` in this directory, then `node cli.js`. The TypeScript source needs Node.js 22.18+; on older Node, run `cli.js` for build-it-yourself / prebuilt / alternative-runtime options.
From compatibility in the SKILL.md frontmatter.
Context cost
Heygen loads about 4.4k tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 117 tokens; SKILL.md has 1,493 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Its licence (Elastic-2.0) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,493 words (~4,356 tokens).
“Agent-callable tools for HeyGen's AI video platform, over the public HeyGen v3 API (https://api.heygen.com). Generate AI avatar videos from a script or audio, generate short cinematic clips from a prompt, translate and lip-sync existing videos, drive the prompt-to-video Video Agent…”
