Make Skill Template

A meta-skill for creating new Agent Skills. Use this skill when you need to scaffold a new skill folder, generate a SKILL.md file, or help users understand the Agent Skills specification.

When to Use This Skill

• User asks to "create a skill", "make a new skill", or "scaffold a skill"
• User wants to add a specialized capability to their GitHub Copilot setup
• User needs help structuring a skill with bundled resources
• User wants to duplicate this template as a starting point

Prerequisites

• Understanding of what the skill should accomplish
• A clear, keyword-rich description of capabilities and triggers
• Knowledge of any bundled resources needed (scripts, references, assets, templates)

Creating a New Skill

Step 1: Create the Skill Directory

Create a new folder with a lowercase, hyphenated name:

skills/\x3Cskill-name>/
└── SKILL.md          # Required

Step 2: Generate SKILL.md with Frontmatter

Every skill requires YAML frontmatter with name and description:

---
name: \x3Cskill-name>
description: '\x3CWhat it does>. Use when \x3Cspecific triggers, scenarios, keywords users might say>.'
---

Frontmatter Field Requirements

Description Best Practices

CRITICAL: The description is the PRIMARY mechanism for automatic skill discovery. Include:

1. WHAT the skill does (capabilities)
2. WHEN to use it (triggers, scenarios, file types)
3. Keywords users might mention in prompts

Good example:

description: 'Toolkit for testing local web applications using Playwright. Use when asked to verify frontend functionality, debug UI behavior, capture browser screenshots, or view browser console logs. Supports Chrome, Firefox, and WebKit.'

Poor example:

description: 'Web testing helpers'

Step 3: Write the Skill Body

After the frontmatter, add markdown instructions. Recommended sections:

Step 4: Add Optional Directories (If Needed)

Example: Complete Skill Structure

my-awesome-skill/
├── SKILL.md                    # Required instructions
├── LICENSE.txt                 # Optional license file
├── scripts/
│   └── helper.py               # Executable automation
├── references/
│   ├── api-reference.md        # Detailed docs
│   └── examples.md             # Usage examples
├── assets/
│   └── diagram.png             # Static resources
└── templates/
    └── starter.ts              # Code scaffold

Quick Start: Duplicate This Template
