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
for on-screen text
