Demo Precacher

The golden rule of AI demos: never rely on live API calls during a presentation. This skill provides a systematic approach to pre-generating and verifying all demo content before you go live.

Why This Exists

In a 48-hour hackathon, we had 18 stories across 10 languages with audio narration, sound effects, and background music. During the demo, the Mistral API had a 3-second latency spike. Because everything was pre-cached, the demo played flawlessly from cache while the audience assumed it was generating in real-time.

The Pattern

async def precache_demo():
    scenarios = [
        {"name": "Sophie", "language": "fr", "prompt": "A story about cloud whales..."},
        {"name": "Kai", "language": "ja", "prompt": "A story about bamboo forests..."},
    ]
