Skill Creator

Create a new skill by generating a SKILL.md file with YAML frontmatter.

Steps

Identify the task pattern the user wants to capture as a skill
Write clear, specific instructions that an AI agent can follow
Create a directory with this structure:

my-skill/
├── SKILL.md          # Instructions + frontmatter
├── template.md       # (optional) Template files
└── example.py        # (optional) Example scripts

The SKILL.md must have this format:

markdown
---
name: skill-name
description: "Brief description of what this skill does"
tags: [category1, category2]
version: "1.0.0"
---

# Skill Name

## Purpose
What this skill accomplishes.

## Instructions
Step-by-step instructions for the agent.

## Examples
Concrete examples of input/output.

Guidelines

Name: lowercase with hyphens (e.g., api-client-generator)
Description: one sentence, starts with a verb
Instructions: specific enough that another agent can execute without context
Include edge cases and error handling guidance
Add examples showing expected input and output
Place resources (templates, schemas) as separate files next to SKILL.md
