The Skin Ledger

Module 03 · The Intelligence Layer

An LLM layer that turns analysis into conversation.

It reads Analyzer output, builds the routine in the right order, explains the condition in plain language, and sets honest timelines. This demo runs on the Codex's own knowledge base; the production Coach runs on a guardrailed Claude system prompt.

Guardrailed to educate, never diagnose. A tool that touches health advice earns its trust by what it refuses to say.

Skin Coach

It educates, it never diagnoses

And it says so, out loud, in the interface. The distinction is engineered into the prompt, not left to chance.

It sets twelve-week expectations

The single biggest reason people quit a working routine is that nobody told them the timeline. The Coach leads with it.

It knows when to hand off

Red-flag language routes straight to 'see a real dermatologist', and the Condition Library tells you which signs count as red flags.
