Design Harness documentation / Phase 1

How the Harness works, while I build it.

A public set of articles, emails, and build notes about working with AI agents through context, standards, critique, validation, and real product judgment.

03 starting notes Open Planark proof

Three starting notes for the Harness.

Each note explains one part of the system and connects it to a reusable artifact. Start with the shift, map the process, then see what a real product makes visible.

01

Documentation / The shift

The New Era Of AI Design

AI makes output cheaper, but taste, craft, judgment, context, and responsibility become more important.

02

Documentation / The process

The New Design Process

Move beyond prompt, output, ship: intent, context, agent task, prototype, critique, test, validation, and saved learning.

03

Documentation / The proof

A Side Project Is The Fastest Way To Learn AI Design

Planark shows why prompts are not enough: source trust, product judgment, design memory, logs, QA, and saved learning all matter.

Learn from a product that has to work.

Planark is an iOS app in production with real users, live APIs, real data, and real constraints. It is where the Harness meets the decisions that demos can hide.
