Learn how to build, secure, and register custom capabilities for AI coding agents.

1. What is an Agent Skill?

Unlike standard APIs, an Agent Skill is packaged procedure knowledge. It guides agents on how to complete multi-step tasks. It revolves around a SKILL.md specification file, coupled with script workflows.

2. Structuring your SKILL.md

A verified skill requires YAML frontmatter specifying compatibility, name, and allowed tools. Example structure:

SKILL.md

---
name: my-cool-tool
description: Explains how this tool is executed.
license: MIT
compatibility:
  - claude-code
  - cursor
allowedTools:
  - read
  - write
---

# My Cool Tool
When the user asks to debug the database, do the following:
1. Locate the db config in database.json
2. Check active connections
3. Alert about leaks

3. Connecting MCP Servers

Model Context Protocol (MCP) provides external resources. By attaching an MCP server, agents get standardized access to tools, browser controllers, and server logs. Combined with custom skills, MCP enables advanced autonomous capabilities.

4. Security Checklists

To receive a verified 'Verified Badge' and safety Grade A/B, verify your script does not perform remote curls, hardcode secrets, request root access, or write to sensitive directories.
