Build Your First AI Skill is a three-page Forum3 guide for turning a task you keep repeating into a playbook your AI can reuse. It explains that a skill saves the method, not the facts, and lists good skill candidates such as meeting prep, weekly updates, research briefs, action-item summaries and recurring reporting.

The guide has you give the AI five things: a trigger, an input, a method, an output and a human review step. It includes a build prompt for a Weekly Update skill that readers can adapt, a note on using project or custom instructions in ChatGPT, Claude or Copilot when a skills option is not available, and a checklist for testing the skill in a fresh conversation.

Readers finish with a small first skill they know how to judge.
