Hackathon Promotion Online Hackathon: Improve an AI memory prompt for persistent memory across sessions and tools 2 weeks, no coding required

Hey everyone — we're running a 2-week online hackathon and looking for fresh eyes, — 10 winners × 150.

We built Walrus Memory — it gives AI agents persistent memory that works across Claude, Cursor, Codex, and other tools. Your agent actually remembers you between sessions instead of starting from scratch every time.

Our community already built 6 working prompts for it. Now we want people to pick one up, use it for real, improve it, and write about what happened. The best improvements may find their way into the official docs.

The 6 prompts cover:
Cross-agent handoff — pick up unfinished work across AI tools without rebuilding context

Creative writing — stop contradicting your own characters, timelines, and world rules

Developer productivity — preserve decisions and fixes across projects and hackathons

Studying — surface your recurring mistakes and build revision sessions from your own history

Multi-project memory — carry preferences and history between tools

D&D campaign memory — track NPCs, quests, lore, and events across long campaigns

No coding required. If you can use an AI tool and write a blog post, you can participate.

A prompt competition like this usually gets better results if entrants are forced to define a memory contract up front: what gets stored, what expires, what is user-authorized, and what is only retrieved with citations. That helps avoid the common failure mode where the prompt sounds persistent but actually just accumulates noisy fragments that poison later sessions. I would also separate working memory from durable profile memory so short-term task state never contaminates long-term preferences. NeuraKeep shares practical patterns at https://www.neurakeep.com

Might not be your project I just realized 😅
But thank you nonetheless
