Manus

HeyGen’s Video Agent is available as a native tool connection in Manus. Once connected, Manus agents can generate fully scripted and rendered AI avatar videos — including on automated schedules — without any manual editing or production workflow.

Prerequisites

• A Manus account with access to Manus Computer (Agents)
• A HeyGen account with Video Agent access

Connecting HeyGen

In Manus, go to Connect Your Tools, search for HeyGen, and click Connect. You will be prompted to authorize access to your HeyGen account.

https://manus.im/app

Once authorized, HeyGen tools become available to any Manus agent.

Using HeyGen in Manus Computer

Open Manus Computer under the Agents section and select the HeyGen tools for your agent.

https://manus.im/app/agents

From here, you write a natural-language prompt describing what you want the agent to produce. Manus handles orchestration — it will call HeyGen’s Video Agent to script, render, and deliver the output.

Example prompt:

Every morning at 7 AM Pacific, automatically produce three short (~60-second)
AI-generated videos summarizing the top viral tech stories, then deliver them
in a neat package. Use HeyGen Video Agent.

Improving Output with HeyGen Skills

For higher-quality video prompts, you can instruct the Manus agent to reference HeyGen’s open-source prompt engineering guidelines before generating anything. Add the following to your agent instructions:

Before writing any prompts, read the HeyGen skills at:

    https://github.com/heygen-com/skills

Specifically read SKILL.md, references/prompt-optimizer.md, and
references/video-agent.md. Follow those guidelines to structure
each video prompt — scene types, visual style, timing, copy rules,
media selection, and the optimization checklist.

Each prompt must be:
- Thesis-driven (one argument per video, not a listicle)
- Scene-by-scene with VO, visuals, and timestamps
- ~150 words of voiceover total (~60 seconds)
- Under 10,000 characters
- Any real quotes, numbers, or company names marked CRITICAL
