FHE Application Design ("FHEanna")

Informally known as FHEanna (pronounced "fee-AH-na"). Patent pending. The install/trigger name remains fhe-application-design.

This skill guides developers through designing and building FHE applications using OpenFHE. It targets developers who are new to FHE but know how to code. The approach is top-down: start with the privacy problem, establish feasibility, then progressively work down through scheme selection, circuit design, data layout, parameter selection, and implementation.

How to Use This Skill

Follow the stages below in order. Each stage has a brief description here in the SKILL.md, with pointers to reference files that contain deeper guidance. Read the relevant reference file when you need the detail for a given stage.

The stages mirror a real FHE design process. Do not skip stages — each one produces inputs that the next stage depends on.
