prompt engineering, compiled
HowTo AI
A toolkit for people who treat prompts like engineering artifacts. Write structured scaffolds, version every change, and ship results you can reproduce.
Built in public. The Discord is where the recipes, benchmarks, and early builds land first.

Built like a tool, not a prompt dump
/ specsStructured scaffolds
Role, context, constraints, output contract. Every prompt compiles down to a predictable schema instead of a wall of text.
role · context · constraints · output
Versioned iteration
Fork a prompt, diff the change, keep the variant that scored better. Your prompt library behaves like a codebase.
fork · diff · rollback
Model agnostic
One recipe, multiple targets. Adapters normalize tone, token budget, and formatting per model family.

Private by default
Your prompts stay yours. No training on your data, no silent sharing, plain-language policies.
no training · no resale
