# 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

## Skill Directory Structure

```
.github/skills/[skill-name]/
├── SKILL.md                       # Main skill definition
├── scripts/                       # (Optional) Automation scripts
│   └── validate-skill.ps1
├── references/                    # (Optional) Supporting docs
│   ├── pattern-guide.md
│   ├── checklist.md
│   └── examples.md
└── assets/                        # (Optional) Templates/samples
    ├── template.cs
    └── config.yml
```

## Creating a New OnoCoro Skill

### Step 1: Define the Skill Purpose

```
Skill 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

```powershell
# 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:

```markdown
---
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"]
---

# [Skill Name]

### Step 4: Add Supporting Files (Optional)

**scripts/validate-skill.ps1:**
```powershell
# PowerShell script for validation or automation
# Example: Check for missing configurations

param(
    [string]$ProjectPath = "g:\unity\OnoCoro2026"
)

Write-Host "Validating skill requirements..."

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

Write-Host "Validation passed!"
```

**references/pattern-guide.md:**
```markdown
# [Skill Name] Patterns

## Pattern 1

[Description]

```csharp
// Code pattern
```

## Checklist

- [ ] Item 1
- [ ] Item 2
```

**assets/template.cs:**
```csharp
// Template for common code patterns in this skill
```

### Step 5: Document in Skills README

Add entry to [.github/skills/README.md](.github/skills/README.md):

```markdown
| [Skill Name] | [Description] | scripts/ references/ |
|--------------|---------------|---------------------|
```
