Skills Guide

The Skills Guide is the foundational specification for packaging reusable expertise into discoverable capabilities for Claude. It provides a standardized template for SKILL.md files, ensuring that autonomous agents can interpret instructions consistently across personal and project-level environments. This system replaces manual prompt engineering with modular, file-based instructions that Claude activates contextually, reducing repetitive input and improving workflow efficiency for developers and project managers.

• Defines mandatory YAML frontmatter requirements including specific naming conventions (gerund forms) and descriptive triggers.

• Outlines file structure patterns, including simple single-file skills and complex multi-file modules using progressive disclosure.

• Provides best practices for writing concise, high-performance instructions that avoid basic concept explanations in favor of concrete examples and input/output pairs.

• Standardizes dependency management and local tool integration, such as integrating Python scripts for data validation or task automation.

• Enables cross-team collaboration by facilitating project-specific skill sharing via git repositories, ensuring consistency in team workflows.

• Use this guide to bootstrap new project capabilities or standardize existing fragmented prompt libraries.

• Ensure the 'description' field in your YAML frontmatter is granular and intent-focused, as it serves as the primary hook for Claude's autonomous discovery.

• Keep instructions under 500 lines for optimal context management; use separate reference files (e.g., FORMS.md, REFERENCE.md) for deeper documentation.

• Always validate skill performance through iteration; use utility scripts and predefined input/output examples to test agent reliability before deployment.

• Distinguish clearly between personal global skills (~/.claude/skills/) and project-specific skills (.claude/skills/) to maintain scope integrity across different environments.
