What problem does it solve?

Creating well-structured Claude Code skills and slash commands requires understanding official specifications, best practices, and structural patterns. Without proper guidance, developers produce inconsistent, hard-to-maintain, or poorly performing skills that waste context window space and fail to auto-discover correctly.

Core Features & Use Cases

  • Skill Creation: Build new skills from scratch with proper YAML frontmatter, XML structure, and progressive disclosure patterns.
  • Command Migration: Convert existing slash commands to skills or upgrade simple skills to router patterns with workflows and references.
  • Audit & Verification: Audit existing skills against best practice checklists and verify content accuracy against current API documentation.
  • Use Case: A developer building a team skill library can use this to create a new data-processing skill, audit an outdated integration skill, and verify that documented API endpoints remain current.

Quick Start
