Writing Your First Skill / Project Rulebook

Lesson preview

A saved workflow — a Skill or Project rulebook — beats re-prompting from scratch because it captures your actual standard once and applies it every time. The anatomy that makes this work is purpose, inputs, step-by-step process, output format, quality checklist, and examples, with every rule specific and testable rather than vibes. Every time you re-explain a task from scratch in a fresh chat, you're paying a tax — re-establishing context, re-stating your standards, re-correcting the same mistakes you corrected last time. A saved workflow (a Skill, or a Project's standing instructions) pays that tax once and then applies the result every time the task comes up again. This is the shift from prompting to capability-building: instead of having a conversation about how to do something, you write down how it should be done, save it, and invoke it. The AI stops being a tool you have to re-teach and starts being a colleague who already knows your standards. Not every task deserves this treatment. The right candidate is repeated at least twice a month, has a clear quality bar you could describe to someone else, and is fundamentally text-shaped — something involving reading, writing, structuring, or summarizing information rather than physical action. A weekly client report, a proposal intake structure, an email triage routine, a content brief format — these are classic candidates. A one-off strategic decision or a task with no consistent shape is a poor fit; the effort of writing a rulebook only pays off through repetition.

Key terms in this module

Agent skill (SKILL.md)

An agent skill is a folder of instructions, built around a SKILL.md file, that teaches an AI agent how to do one specific task. The agent sees only the skill's name and description until a task matches, then loads the full instructions.
