Create Skill

Create Skill

Create a custom skill from scratch following Metapowers conventions.

Purpose

Create a brand-new skill for any topic. Researches best practices and generates a structured SKILL.md following Metapowers conventions.

Usage

/metapowers:create-skill <topic>

Example:

/metapowers:create-skill flutter widget testing with golden files

What It Does

Clarifies requirements with the user if needed
Researches current best practices via web search
Creates a SKILL.md with proper frontmatter, process steps, and output format
Validates against skill-validator rules (name matches the directory, verb-first description with a "Use when" clause, 120–400 characters)
Installs to .claude/skills/<skill-name>/SKILL.md — the skill is available as /<name> in the next Claude Code session

Skill Format

Created skills follow the standard Metapowers pattern:

YAML frontmatter: name (the directory name), a description shaped <Verb-first sentence>. Use when <the user's situation, at least six words>. with an optional Not for <adjacent thing>; see /<plugin>:<skill>. (120–400 characters), and argument-hint when the skill takes an argument
Prerequisites section
Numbered process steps
Output section with artifact path
