Extension Options

Skills (skills/)

Skills are the preferred format for both model-invoked capabilities and user-invoked slash commands. Create a SKILL.md in a subdirectory:

Model-invoked skill (activated by task context):

---
name: skill-name
description: Trigger conditions for this skill
version: 1.0.0
---

User-invoked skill (slash command — /skill-name):

---
name: skill-name
description: Short description for /help
argument-hint: <arg1> [optional-arg]
allowed-tools: [Read, Glob, Grep]
---

Commands (commands/) — legacy

> Note: The commands/*.md layout is a legacy format. It is loaded identically to skills/ /SKILL.md — the only difference is file layout. For new plugins, prefer the skills/ directory format. This plugin keeps commands/example-command.md as a reference for the legacy layout.

MCP Servers (.mcp.json)

Configure external tool integration via Model Context Protocol:

{
  "server-name": {
    "type": "http",
    "url": "https://mcp.example.com/api"
  }
}

Usage

• /example-command [args] - Run the example slash command
• The example skill activates based on task context
• The example MCP activates based on task context
