Skill Development

What it does

This skill provides guidance for creating effective skills for Claude Code plugins. It acts as an onboarding guide to transform Claude into a specialized agent by equipping it with procedural knowledge. Skills consist of modular packages that extend Claude's capabilities, including specialized workflows, tool integrations, domain expertise, and bundled resources like scripts and references. The core of the skill is the SKILL.md file, which contains metadata and instructions.

When to use it

• When developing skills for Claude Code plugins.
• To create specialized agents with procedural knowledge for specific domains or tasks.
• For incorporating reusable code snippets (scripts) that require deterministic reliability.

Key capabilities

• Specialized workflows: Provides multi-step procedures for specific domains.
• Tool integrations: Offers instructions for working with specific file formats and APIs.
• Domain expertise: Incorporates company-specific knowledge, schemas, and business logic.
• Bundled resources: Includes scripts (Python/Bash), references (documentation), and assets (templates, icons).
• Script execution: Allows for deterministic code execution without constant context loading.
• Reference material: Provides documentation that Claude can load into context as needed.

Example prompts

• "How do I create a skill for Claude Code plugins?"
• "What are the best practices for structuring a SKILL.md file?"
• "Can you show me an example of how to include scripts in a skill?"

Tips & gotchas

• The SKILL.md file's name and description (in YAML frontmatter) are crucial; be specific about the skill’s purpose and usage.
• For large reference files (>10k words), include grep search patterns within the SKILL.md to optimize context loading.
• Avoid duplicating information between the SKILL.md file and reference files—choose one location for each piece of information.
