SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill solves the problem of users lacking standardized, context-efficient guidance to create or update valid custom Skills that extend Agent capabilities with specialized cross-platform development knowledge, workflows, and tool integrations, ensuring compatibility with major Agent platforms including Codex, Claude Code, Cursor, and Trae.

Core Features & Use Cases

  • End-to-End Skill Creation Workflow: Provides a complete 6-step process for creating effective Skills, from understanding use cases to iterating based on real-world usage.
  • Context-Efficient Design Best Practices: Includes guidance on progressive disclosure, concise content writing, and appropriate freedom levels to minimize context window usage while maintaining task effectiveness.
  • Built-in Validation and Tooling: Comes with executable scripts to initialize new Skills, validate existing Skills against structural and content rules, and enforce repo-local categorization standards for cross-platform frameworks.
  • Use Case: For example, a cross-platform mobile developer can use this Skill to create a custom Skill that encapsulates React Native TurboModule implementation workflows, eliminating the need to reload detailed implementation steps into the Agent's context for every related request.

Quick Start

Use the create-skill Skill to build a new custom Skill for your cross-platform development project, following the provided initialization, editing, and validation guidelines.

FAQPage Schema
How do I create custom skills to extend Agent capabilities for cross-platform development?

To create custom skills, use a standardized 6-step workflow that encapsulates repeatable cross-platform development processes into modular, context-efficient units. This ensures specialized knowledge and tool integrations are compatible with major Agent platforms.

What is progressive disclosure in skill creation and why does it matter?

Progressive disclosure in skill creation is a design practice that minimizes context window usage while maintaining task effectiveness. It provides concise content and appropriate freedom levels, ensuring Agents receive only necessary information for each specific request.

Can I use created skills with Codex, Claude Code, Cursor, and Trae?

Yes, created skills are compatible with major Agent platforms including Codex, Claude Code, Cursor, and Trae. The skill creation process enforces standardized structure and cross-platform framework validation to ensure interoperability across these environments.

How do I validate custom skills against repo-local categorization rules?

You validate custom skills using built-in executable scripts that check structural and content standards against repo-local categorization rules. This validation ensures your modular skills meet cross-platform framework requirements before deployment.

What's the best way to encapsulate framework-specific guidelines into modular skills?

The best way to encapsulate framework-specific guidelines is using the provided initialization scripts to generate modular skill units. This approach packages deterministic helper scripts and workflows, eliminating the need to reload detailed implementation steps repeatedly.

When do I need to build a custom skill for my Agent workflows?

You need to build a custom skill when you require encapsulation of repeatable cross-platform development processes or framework-specific guidelines. This is essential when standard Agent capabilities lack specialized tool integrations or deterministic workflow guidance.
