Skill Creator

Skills are the unit of capability in Claude Code. A well-built skill is the difference between an agent that handles a task reliably and one that improvises badly every time.

This skill teaches you how to build skills correctly — from scratch, following the official Claude Code specification.

What you get:

• Complete SKILL.md specification: required fields, optional fields, frontmatter schema
• Tool allowlists: how to restrict which tools a skill can use
• Trigger design: when should a skill activate vs. stay dormant
• Slash commands: /command-name patterns and how to invoke them
• Validation: how to test and validate skills before shipping
• Anti-patterns: why vague triggers fail, how to avoid skill bleed

Skill types covered:

• Instructional skills (guidance and protocol injection)
• Tool-restricted skills (sandboxed capabilities)
• Slash command skills (user-invocable workflows)
• Compound skills (multi-step workflows with dependencies)

Includes: SKILL.md template, frontmatter reference, trigger phrase examples, a validation checklist, and worked examples of simple, intermediate, and advanced skills.

Use when creating new skills for your agents, improving existing skills, or understanding why a skill isn't triggering correctly.
