---

Overview

Purpose: Add tools and capabilities to your agent (file operations, API calls, code execution) Connection: Right handle of main agent card Color: Red Icon: 🛠️ Required: Optional (0 to many)

What are Skills?

Skills are folder-based capabilities that define what your agent can do:

• Read and write files
• Execute Python/JavaScript code
• Call external APIs
• Process data
• Interact with systems

---

Skill Structure

Each skill is a folder containing:

my-skill/
├── SKILL.md              # Skill definition (required)
├── scripts/              # Executable scripts
│   ├── main.py
│   └── helper.sh
├── references/           # Documentation
│   └── api-docs.md
└── assets/               # Resources
    └── config.json

---

SKILL.md Format

The skill definition file uses YAML frontmatter + markdown:

---
name: GitHub API
description: Interact with GitHub repositories
version: 1.0.0
author: Your Name
---

# GitHub API Skill

This skill provides GitHub API integration.

## Usage

Call the skill with:
- Repository name
- Action (get, create, update, delete)
- Parameters (issue number, PR number, etc.)

## Examples

Get repository info:
Input: repo=owner/name, action=get

Create issue:
Input: repo=owner/name, action=create_issue, title="Bug", body="Description"

Best Practices

✅ Do:

• Keep skills focused (one responsibility)
• Document parameters clearly
• Include usage examples
• Handle errors gracefully
• Use scripts for complex logic

❌ Don’t:

• Create monolithic “do everything” skills
• Hardcode credentials (use config)
• Skip error handling
• Ignore security implications

Next Steps

• Memory Node - Add persistent knowledge
• Commands Node - Create slash commands
