Make Skill Template (OnoCoro)

Create new Agent Skills for GitHub Copilot from prompts or by duplicating this template. This template is customized for OnoCoro specialized capabilities with bundled resources (scripts, references, guides).

Use when asked to:

• "Create a skill" — Build a new Agent Skill from scratch
• "Make a new skill" — Scaffold new capability
• "Build a skill for X" — Specialized skill for OnoCoro feature
• Building specialized AI capabilities with bundled resources

What is an Agent Skill?

An Agent Skill is a self-contained folder containing:

• SKILL.md — Main instruction file with guidance and examples
• scripts/ — PowerShell/Python scripts for validation or automation
• references/ — Supporting documentation, checklists, patterns
• assets/ — Code samples, templates, configuration files

Creating a New OnoCoro Skill

Step 1: Define the Skill Purpose

CopySkill Name: [Name]
Purpose: [What the skill does]
Target Audience: [AI Agent / Developer]
Use Cases:
  - [Use case 1]
  - [Use case 2]

Step 2: Create Skill Directory

Copy# Create skill folder
New-Item -Type Directory -Path ".github/skills/[skill-name]"

# Create SKILL.md
New-Item -Type File -Path ".github/skills/[skill-name]/SKILL.md"

# Create subfolders if needed
New-Item -Type Directory -Path ".github/skills/[skill-name]/scripts"
New-Item -Type Directory -Path ".github/skills/[skill-name]/references"

Step 3: Write SKILL.md

Use this template:

Copy---
name: [skill-name]
description: [One-sentence description of what the skill does. Include "OnoCoro" context.]
compatibility: [e.g., "Works with GitHub Copilot", "Requires X MCP Server"]

)

Write-Host "Validating skill requirements..."

if (-not (Test-Path "$ProjectPath/.github/skills")) {
    Write-Error "Skills folder not found"
    exit 1
}
