Pre-launch sub-skill: Validation & testing

Tests the built product against the original success definition and the approved scope, and reports anything that shipped outside it. Gates the other three sub-skills in this phase.

In one minute

A sub-skill of Pre-launch activities, invoked first of its four, right after Implementation reports a working, deployed build.
Checks the product against two different, earlier files: the success definition from idea.md, and the scope from definition.md, not just whether the code runs.
Its explicit job is to report scope drift, features that shipped but were not in the approved definition, not silently accept it.
The one sub-skill in this phase that gates the rest. SEO, Accessibility, and UI/UX polish all wait for this one to pass first.

name: validation-and-testing
description: Tests the built product against the success definition from understanding-of-idea and the scope from product-definition. Use after implementation, before seo and accessibility.
---
Read docs/product/idea.md for the success definition and docs/product/definition.md for the core features.

Write and run tests against both.

Report any feature that shipped outside the approved scope.

Where it fits

Invoked by Pre-launch activities, first of its four sub-skills, right after Implementation. Once it passes, SEO, Accessibility, and UI/UX polish can all run, in any order.
