I Missed the Hackathon Deadline by 60 Seconds — But Here's What I Built with AI Agents

I recently participated in the Agent Development Kit Hackathon with Google Cloud and poured weeks into building a fully functional, GPU-powered, multi-agent content generation platform.

But just 60 seconds before the submission deadline…
I missed it.

No worries — this blog walks you through what I built, how it works, and how you can explore or fork it.

🤖 Meet ContentCrafter AI

ContentCrafter AI is a powerful autonomous blog generator that:

• Plans content topics

• Writes drafts using LLMs

• Refines tone and structure

• Predicts engagement score

• Generates inline images with Stable Diffusion

It’s built with Gemini 1.5 Flash, Streamlit, and Stable Diffusion v1.5, running on an RTX 4060 GPU.

🟢 Try it live: https://contentcrafterai.streamlit.app

🧠 How It Works (Agent Pipeline)

ContentCrafter AI runs a pipeline of autonomous agents:

1. Planner Agent — Validates and expands user topics

2. ContentWriter Agent — Writes draft with LLM

3. ContentEditor Agent — Suggests edits and structure

4. ToneRefiner Agent — Adjusts for tone alignment

5. EngagementPredictor Agent — Scores blog with reasoning

6. Stable Diffusion — Generates images inline from prompts

💡 What I Learned

• Multi-agent reasoning is super powerful

• Integrating visual + text output is non-trivial but rewarding

• Race against deadline is real 💀

🧵 Closing Thoughts

This project was built entirely during the hackathon window and reflects everything I’ve learned about autonomous agents in production.

Even though I missed the deadline by seconds, I’m sharing this openly because:

Great projects don’t need perfect timing. They need to be seen.

If you liked this, please ⭐ the repo, try the demo, or reach out.

Thanks for reading. Built with ❤️ by Avisikta.
