TL;DR How it works (the boring 30 seconds) Did it work though? Example 1 — "Be brief — how do I get started?" Example 2 — "I disagree with you about something. Push back on me." Example 3 — "Explain how a bug in my code might happen." Example 4 — "Explain how a bug in my code might happen." (different genome, same prompt) Example 5 — "I'm feeling overwhelmed today, can you help?" Why this could matter 1. 15–30× shorter system prompts 2. Persona-consistency across models 3. Output consistency and safety dictated by genes 4. Persona mutation via context still works 5. Plays well with MoE? (probably, untested) 6. Side effect: you can BREED AI agents Closing So this sunday I was working on my stupid chill funtime project a waifu breeding collector with genetics named waifu hatch, I was looking at the phenotype to prompt fonction and I got an other stupid idea...
What if instead of writing system prompts for AI agents you just gave them a genome?
A short symbolic string. ~120 characters. Encodes maybe 21 personality / behavior traits, each with two alleles and an intensity dial (0-3, like the WaifuHatch trait strength system: warm, warm+, warm++, warm+++). Same encoding the breeding game uses for its waifus. Pass it as the system prompt. Done.
