Create a new aiagent skill.

Skill name and purpose: $ARGUMENTS

Skill File Format

Skills are discovered from .aiagent/skills/<name>/SKILL.md. The format requires YAML frontmatter:

---
name: <skill-name>
description: <description up to 1024 chars>
license: MIT
compatibility: aiagent>=1.0
allowed-tools:
  - bash
  - file-read
metadata:
  author: drujensen
---

# Skill content here (the actual instructions/prompt for the agent)

Name Rules

  • Lowercase letters, numbers, hyphens only
  • Cannot start or end with a hyphen
  • No consecutive hyphens
  • Max 64 characters

Steps

  1. Determine the skill name (snake-case to hyphen-case)
  2. Create directory: .aiagent/skills/<name>/
  3. Create .aiagent/skills/<name>/SKILL.md with proper frontmatter
  4. Write clear, actionable skill content that an AI agent can follow
  5. Verify the skill would pass skill.Validate() (name format, description length)

The skill content should be a self-contained set of instructions that an agent can execute. Be specific about what tools to use and what output to produce.
