Claude Code skills for web agencies, for Codex, Cursor & Gemini CLI too

Supercharge your agency.

Battle-tested AI skills for Claude Code, Codex, Cursor and Gemini CLI. Your agents work to the same rules, check their own work, and stop telling you it’s done when it isn’t.

Find your pack

Built from 25+ client projects: traditional WordPress, headless WordPress, and web apps with no WordPress at all.

The problem

Fast agents. Slow checking.

Everyone has the same models now. The agencies that pull ahead won’t have a smarter one. They’ll have agents that know what done looks like, so the time they save isn’t spent checking the work by hand.

  1. “Done” that isn’t done

    The agent says the layout is fixed, the email looks right, the site is live. You find out it wasn’t from a client, or a customer.

  2. Every tool, its own rules

    Claude Code, Codex, Cursor and Gemini CLI each read their own instructions, so what you teach one never reaches the others.

  3. Sessions that collide

    Two agents on one project commit over each other’s work, and a key pasted into the chat stays in the transcript.

How it works

What’s a skill pack?

A skill pack is a set of Claude Code skills for one kind of job. Install it once, and from then on your agent runs the check before it answers, prints what it measured, and tells you pass or fail. You read a result instead of redoing the work.

  1. Instructions your agent follows

    A skill is written guidance an AI coding agent follows for one kind of job: how to check it, and what counts as done.

  2. Checks it runs

    Most skills come with small scripts the agent runs on your computer, so each check prints what it measured and passes or fails.

  3. One pack, one job

    Each pack groups the skills for one kind of work: web pages, several agents, email, WordPress, a web app, campaign tracking or site speed. You install it once.

Every pack

Every pack at a glance.

Each pack sells on its own, once, with every future version included. The bundle holds all seven, plus every pack added after them.

  • For you if
    You build websites or web apps with an AI coding agent and check its work by hand.
    Needs
    Node.js 18 or newer, plus Playwright and sharp in your project. Your agent can install them.
  • For you if
    You use more than one AI coding tool, like Claude Code and Codex, on the same projects.
    Needs
    A project in git and a terminal with bash. Some scripts also use jq or python3.
  • For you if
    An AI agent builds the emails your product or your clients send.
    Needs
    Node.js 18 or newer, and Playwright for the checks that render in a browser.
  • For you if
    Your WordPress site is built with Bricks Builder, with Automatic.css or SureCart if you use them.
    Needs
    Bricks 2.4 or later, and a way for the agent to reach WordPress: WP-CLI or an MCP server.
  • For you if
    You’re building a web app with sign-in or payments on Supabase, Stripe or Cloudflare Pages.
    Needs
    Node.js 18 or newer. Nothing else to install: no packages, no browser.
  • For you if
    You run Meta ads for your own sites or your clients’, and want each lead and sale tied to the ad that brought it.
    Needs
    Each site on Cloudflare with its DNS proxied, and Node.js 18 or newer. Nothing else to install.
  • For you if
    A WordPress or code-built site scores badly on a phone or feels slow to open, and you want it faster.
    Needs
    Node.js 18 or newer, and Playwright and sharp in the project you run the scripts from. Lighthouse 13 needs Node 22.19 or newer.
  • For you if
    Your work crosses the packs: a site and the email it sends, or an app and its CRM.
    Needs
    Node.js 18 or newer, and Playwright for the page checks. Your agent can install it.

New to coding agents?

Start with the agent.

  • Claude Code
  • Codex
  • Cursor
  • Gemini CLI

When I started, I wasn’t very comfortable in a terminal. By working with an AI coding agent, I got to where I am now, and learned along the way.

Jon Phillips Matchless Web Studio LLC, the company behind Heavy Artillery

A coding agent is an AI that works on a project’s files on your own computer: it reads the code, changes it and runs commands. Claude Code, Codex, Cursor and Gemini CLI are the common ones.

Hosted builders such as Lovable, Bolt and v0 run their own AI inside their site. The packs can’t plug into that. They need the project in files that a coding agent can open.

Four steps from here

  1. Get your project onto your computer

    Lovable and v0 can sync a project to GitHub, where you can copy it to your computer. Bolt can download it as a zip file.

  2. Install a coding agent

    Claude Code has a step-by-step guide for people who have never used a terminal. Once it runs, your agent can type the install commands for you.

  3. Start with the free field guide

    Six questions to ask any AI that says the work is done. It works whatever built your site.

  4. Come back when “done” isn’t done

    When your agent says it’s finished and you still find problems, answer the two questions and pick the pack for that job.

Coming from WordPress?

Keep it, mix it or leave it.

Every project I built used to run on WordPress. Then I started using it in new ways, and building websites, landing pages and even web apps without it. These packs cover each step of that path, because I’ve taken every one.

  • Keep WordPress

    Your site stays on WordPress, built with Bricks. Claude Code, or whichever agent you use, changes the live site with a backup before every write, and checks the real page after.

    The packs for it

  • Mix it with code

    WordPress keeps what it does well, like a store, while the pages people land on are built in code. This site works that way: React pages on Cloudflare Pages, and a store on WordPress.

    The packs for it

  • Build without it

    Websites, landing pages and web apps with no WordPress at all: code your agent writes, on a host like Cloudflare Pages, with sign-in and payments from services like Supabase and Stripe.

    The packs for it

Who’s behind it

Jon Phillips, laughing over a cup of coffee

Built on real client work.

Every rule in these packs started as something an agent told me was done that wasn’t. Across 25+ client projects, from traditional WordPress to headless WordPress to web apps with no WordPress at all, I wrote down what went wrong and the check that would have caught it. The packs are those checks, written so your agent runs them before you have to.

Questions

Questions before you buy.

Which AI coding agents does it work with?

Claude Code, Codex, Cursor and Gemini CLI. The skills are plain text files and the checks are plain Node and shell scripts, so any agent can run them. Claude Code loads the skills from its skills folder; Codex, Cursor and the rest take a skill pasted into your repository’s AGENTS.md, and Gemini CLI reads that file once its settings name it.

Do these work as Codex skills?

Yes. Each skill is a SKILL.md file of plain instructions, and its checks are Node and shell scripts that Codex runs like any other command. Paste a skill into your repository’s AGENTS.md and Codex follows it; Claude Code loads the same files from its skills folder.

Is a skill the same as an MCP server?

No. An MCP server gives your agent new tools to call, like a connection to a database or a WordPress site. A skill tells the agent how to do a job and how to check it. They work together: the WordPress Pack can reach your site through an MCP server or WP-CLI, and still checks the real page afterward.

Do I need to know how to code?

No, but you need a coding agent that works on files on your own computer, and you’ll read what it prints. The agent types the commands; the skill tells it what to check and what counts as done. Starting from nothing? The “New to coding agents?” section above has four steps from here.

I build with Elementor or Divi. Is there anything for me?

Yes. The WordPress Pack is written for Bricks 2.4 or later, except its sign-in screens skill and two SureCart fixes, which work on any theme. The other packs don’t care how a site was built: Spotter Round checks the pages themselves in a browser, and the App Stack Pack covers SureContact and OttoKit behind any site, WordPress included.

One pack or the bundle?

One pack, if your work fits one job: the two questions above name it. The bundle holds all seven packs and every pack added later. Already own a pack? Each one you own counts toward the bundle on the upgrade page.

What do updates look like?

Numbered downloads with a list of what changed, one changelog per pack. Every future version is included at no charge, and you’re never forced to update.

Can I use it for client work?

Yes, that’s what it’s for. One company covers every project that company delivers.

Refunds?

Fourteen days, no questions. A product about checking things that argued with you over a refund would be a poor advertisement for itself.
