Skill Creator

Skills are modular packages that extend Claude's capabilities by providing specialized knowledge, workflows, and tools.

Core Principles

Concise is Key

The context window is a shared resource. Only add context Claude doesn't already have. Challenge each piece: "Does Claude really need this?"

Skill Creation Process

Step 1: Understand with Examples

Gather concrete examples of how the skill will be used. Ask:

"What functionality should this skill support?"
"What would a user say that should trigger this skill?"

Step 2: Plan Reusable Contents

Analyze examples to identify:

Scripts: Code that gets rewritten repeatedly
References: Documentation Claude needs to reference
Assets: Templates, images for output

Step 3: Initialize

Create the skill directory structure with SKILL.md and resource folders.

Step 4: Implement

Start with reusable resources (scripts, references, assets)
Write clear SKILL.md with proper frontmatter
Test scripts by actually running them

Step 5: Iterate

Use the skill on real tasks, notice struggles, improve.
