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/<skill-name>/
└── SKILL.md # Required
Step 2: Generate SKILL.md with Frontmatter
Every skill requires YAML frontmatter with name and description:
---
name: <skill-name>
description: '<What it does>. Use when <specific triggers, scenarios, keywords users might say>.'
---
Frontmatter Field Requirements
| Field | Required | Constraints |
|---|
name | Yes | 1-64 chars, lowercase letters/numbers/hyphens only, must match folder name |
description | Yes | 1-1024 chars, must describe WHAT it does AND WHEN to use it |
license | No | License name or reference to bundled LICENSE.txt |
compatibility | No | 1-500 chars, environment requirements if needed |
metadata | No | Key-value pairs for additional properties |
allowed-tools | No | Space-delimited list of pre-approved tools (experimental) |
Description Best Practices
CRITICAL: The description is the PRIMARY mechanism for automatic skill discovery. Include:
- WHAT the skill does (capabilities)
- WHEN to use it (triggers, scenarios, file types)
- 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:
| Section | Purpose |
|---|
# Title | Brief overview |
## When to Use This Skill | Reinforces description triggers |
## Prerequisites | Required tools, dependencies |
## Step-by-Step Workflows | Numbered steps for tasks |
## Troubleshooting | Common issues and solutions |
## References | Links to bundled docs |
Step 4: Add Optional Directories (If Needed)
| Folder | Purpose | When to Use |
|---|
scripts/ | Executable code (Python, Bash, JS) | Automation that performs operations |
references/ | Documentation agent reads | API references, schemas, guides |
assets/ | Static files used AS-IS | Images, fonts, templates |
templates/ | Starter code agent modifies | Scaffolds to extend |
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
- Copy the
make-skill-template/ folder
- Rename to your skill name (lowercase, hyphens)
- Update
SKILL.md:
- Change
name: to match folder name
- Write a keyword-rich
description:
- Replace body content with your instructions
- Add bundled resources as needed
- Validate with workspace diagnostics (
get_errors) on the new SKILL.md
Validation Checklist
Troubleshooting
| Issue | Solution |
|---|
| Skill not discovered | Improve description with more keywords and triggers |
| Validation fails on name | Ensure lowercase, no consecutive hyphens, matches folder |
| Description too short | Add capabilities, triggers, and keywords |
| Assets not found | Use relative paths from skill root |
Create a Skill with AI
Type /create-skill in Agent mode chat and describe the skill you want. The agent asks clarifying questions and generates a SKILL.md file with frontmatter, steps, and optional scripts. This is the fastest path to a new, well-formed skill.
