Kit Builder

Create custom skills, agents, and workflows to extend ClaudeKit Marketing for your specific needs.

What This Skill Does

Challenge: Every marketing team has unique processes and tools. The built-in skills in ClaudeKit Marketing are great for common use cases but may not cover the specifics of each business.

Solution: The kit-builder skill provides a framework to create custom skills, agents, and workflows — from simple slash commands to complex multi-agent pipelines — and integrate them into ClaudeKit Marketing.

Activation

Implicit: Activates automatically when a new skill needs to be built or extended.

Explicit: Activate via prompt:

Activate kit-builder skill to create [skill/agent/workflow] for [purpose]
