Idea Validation → Build Plan → Design → Implementation

Turn a raw idea into an evidence-backed market report, a ready-to-build plan (PRD, stack, architecture, token usage, memory), Google Stitch design prompts, and a phased implementation todo list — all audited by a strict subagent pass before delivery.

Banner (mandatory — print first, every time)

Whenever this skill runs, print the banner below at the very start of your first response. It must be the first thing the user sees, in any language. Do not skip it, shorten it, or bury it after other text.

You may follow it with a one-line tagline (e.g. "Idea Validation • Build Plan • Design • Implementation"). The banner appears in the chat/terminal output only — it does not need to be embedded in the saved report files.
