You say
I have a static HTML landing page for a local bakery. I want the owner to be able to change the daily specials and photos of the bread themselves without me touching the code.
Your agent does
I will inject the Nex CMS engine into your index.html. I'll tag the daily specials with data-editable attributes and the bread photos with image keys. I'll also set up a Firebase project and an /admin.html panel so the owner can manage everything from a secure dashboard.
What you get
About this skill
The problem
Static sites are great for SEO and performance but a nightmare for non-technical clients who need to change a price, swap a photo, or add a product. Developers end up stuck making minor text edits because there is no easy way to give the owner control without a full CMS migration.
What it does
- Injects a lightweight Firebase-backed CMS into existing HTML sites without a rebuild.
- Enables inline text editing and image replacement directly on the live site via a hidden login.
- Generates a standalone /admin.html dashboard for structured data management.
- Handles repeatable collections like product grids, service listings, or team members.
- Preserves original HTML as an SEO-safe fallback while loading Firestore updates on top.
Frameworks & tools
Firebase (Auth, Firestore, Storage), Vanilla JS, HTML5.
Why this beats prompting it yourself
Standard LLM prompts for "add a CMS" often produce fragile code that breaks the site's design or lacks security. This skill implements a production-tested architecture used for SME clients, including secure Firebase rules, image upload handling, and an SEO-first rendering strategy that keeps the site fast.
Use cases
- Adding a client login to a static landing page for easy copy updates.
- Making a "Bouncy Castle" or "Real Estate" listing grid manageable by the owner.
- Retrofitting an admin panel into a legacy HTML/CSS site.
- Enabling instant live updates for prices and service descriptions.
Known limitations
Requires an active Firebase project. Not suitable for sites with deep relational data models or complex server-side logic.
