## Who

I run marketing assessments. Every client tab needs the same SEO stack against the live URL, without hunting bookmarklets.

## What

Public **michaelmonetized/Assessment-Toolbar**. Chrome MV3. Name **Marketing Assessments**. v**1.0**. HEAD `9652620`. **6** commits. Pink #ffc9dd top strip: SpyFu, SiteLiner, Rich Results, Schema, Mobile-Friendly, WAVE, Wayback, Whois, plus FB/NAP prompts, missing-alt highlighter, title clipboard, and Ctrl+Alt+M. GPL-3.0. No package.json.

Manifest + README promise **google lighthouse**. `content.js` has **zero** Lighthouse/PageSpeed link. `background.js` admits it never knew what the file is for and re-runs `content.js` while declarative content scripts already load it. Perms: activeTab + scripting only. Rich Results / Mobile-Friendly get `location.hostname`. Five tools are static. hustlelaunch.com/assessment-toolbar returns **404**.

## Where

github.com/michaelmonetized/Assessment-Toolbar (public). Unpacked root. No CWS. No demo host. hustlelaunch.com root is live; product paths are not.

## When

**2024-08-16.** init + pre-flight.

**2024-08-22.** ready.

**2026-01-31.** STRIPE.md sync.

**2026-06-22.** nightly metadata; empty nightly HEAD `9652620` same day.

## Why

Assessment strip that advertises Lighthouse without shipping it, and a service worker that dual-loads while admitting it does not know its job.

**Engagement Q:** Add PageSpeed/Lighthouse and drop the dual-load SW tonight, or leave v1.0 lying in its own description?
