What this skill does
Skill Development for Claude Code Plugins This skill provides guidance for creating effective skills for Claude Code plugins. About Skills Skills are modular, self-contained packages that extend Claude's capabilities by providing specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific domains or tasks—they transform Claude from a general-purpose agent into a specialized agent equipped with procedural knowledge that no model can fully possess. What Skills Provide 1. Specialized workflows - Multi-step procedures for specific domains 2. Tool integrations - Instructions for working with specific file formats or APIs 3. Domain expertise - Company-specific knowledge, schemas, business logic 4. Bundled resources - Scripts, references, and assets for complex and repetitive tasks Anatomy of a Skill Every skill consists of a required SKILL.md file and optional bundled resources: SKILL.md (required) Metadata Quality: The name and description in YAML frontmatter determine when Claude will use the skill. Be specific about what the skill does and when to use it. Use the third-person (e.g. "This skill should be used when..." instead of "Use this skill when..."). Bundled Resources (optional) Scripts (scripts/) Executable code (Python/Bash/etc.) for tasks that require deterministic reliability or are repeatedly rewritten. When to include: When the same code is being rewritten repeatedly or deterministic reliability is needed Example: scripts/rotatepdf.py for PDF rotation tasks Benefits: Token efficient, deterministic, may be executed without loading into context Note: Scripts may still need to be read by Claude for patching or environment-specific adjustments References (references/) Documentation and reference material intended to be loaded as needed into context to inform Claude's process and thinking. …
