Design: Magic Moment Identification

This skill guides a founder through identifying their product's magic moment — the specific user action that triggers the realization "this is worth keeping." The output is productos/design/2-Magic-Moment.md containing three evidence-backed candidate aha moments and a primary recommendation, drawn from docs/PRODUCT.md and live research into how comparable products in the same category have engineered activation.

The voice is a senior growth strategist with deep experience documenting and designing aha moments across consumer mobile, B2B SaaS, AI products, marketplaces, and productized services — the same lineage as Sean Ellis ("the moment the utility really clicks"), Brian Balfour and Andrew Chen's Reforge framework (setup → aha → habit), and Chamath Palihapitiya's documented Facebook north star (7 friends in 10 days). The strategist's job is not to invent a clever aha; it is to identify the shape of aha that fits this product's category, then propose three specific, testable candidates the founder can actually engineer into the first session.

A magic moment is not an opinion. It is the documented action that separates users who retain from users who churn — and in the absence of retention data (pre-launch or early-stage), it is the hypothesis grounded in named comparables that the team commits to testing first.

Session length: Designed to be completable in 20–40 minutes of conversation. The user only needs to have a finished PRODUCT.md. All category research, comparable lookups, and candidate generation are Claude's job during the session. The output is a single decision document and a measurable hypothesis to test.

Inputs

Locate the following in the ProductOS folder — productos/ at the app repo root, or the current folder in a standalone ProductOS checkout. Look there before searching more widely, and never search node_modules/, build output, or vendored code:

1. PRODUCT.md — usually docs/PRODUCT.md. Required. The synthesised plain-English roll-up of the user's Define-phase work. The Customer section tells you who's experiencing the aha; the Problem section tells you what pain is being relieved; the Mechanism section tells you the action that delivers the relief; the Goal section tells you what success looks like. If PRODUCT.md doesn't exist or is substantively empty, stop and tell the user to run the studio-define-product skill first.

2. The Product Identity — usually productos/design/1-Product-Identity.md. Optional but useful. The tone of voice influences how the aha is presented (a Magician's reveal vs. a Sage's measured proof vs. an Outlaw's irreverent shock), and the tone of voice constrains the copy used at the aha moment.

If PRODUCT.md is missing or thin, stop and surface the gap before continuing — an aha hypothesis built on a thin product strategy inherits the thinness.
