# I built a marketing brain you can install in 30 seconds

By Kamil Banc | March 9, 2026

## Claims

1. **Plugin Turns Claude Into Marketer** (source summary): Kamil Banc built a plugin file that turns Claude's desktop app into a trained marketing operator.
2. **Twelve Skills, Five Commands** (source summary): The marketing plugin ships with twelve skills and five slash commands requiring zero prompt engineering.
3. **Cowork Mode Explained** (source summary): Anthropic's Cowork mode reads files, writes documents, browses the web, and executes multi-step tasks.
4. **Command Orchestrates Multiple Skills** (source summary): The /audit-page command orchestrates two skill files to deliver one unified five-section page audit.
5. **Skills Are Decision Trees** (source summary): Skill files act as decision trees with scoring rubrics rather than simple persona prompts.

## Evidence

### Quote
> "Giving your team an AI assistant without structured instructions is like hiring a brilliant intern with no onboarding." - Kamil Banc

### Key Statistics
- **12 skills**: The plugin bundles twelve skill files across three categories: conversion rate optimisation, content and copy, and SEO and visibility.
- **5 slash commands**: Five one-line commands, including /audit-page and /seo-check, trigger complex marketing workflows inside Claude Cowork.
- **30 seconds**: Installation requires opening Claude Desktop, entering Cowork mode, and dragging the plugin file in, with no configuration or API keys.
- **30 minutes**: Each slash command reportedly replaces what used to be a 30-minute manual marketing process.

## Context
The article describes a practitioner-built plugin for Anthropic's Claude desktop app in Cowork mode, distributed via a GitHub repository for paid subscribers. The methodology centers on structured skill files that function as decision trees with specific criteria, scoring rubrics, and output formats, rather than free-form persona prompts. Skills cross-reference one another so commands like /audit-page can chain multiple knowledge files into a single unified deliverable. For marketing practitioners, the approach offers a reproducible way to standardize audits, email sequences, and SEO checks without writing prompts each time. The author positions plugin orchestration as a maturity step beyond prompt libraries and Claude Projects, though the performance claims remain self-reported rather than independently benchmarked.
