SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Designing and maintaining portable agent skills across multiple agents is error-prone and fragmented. This Skill provides a standardized workflow to create, update, and document skills that work across Claude Code, Gemini CLI, Cursor, and other platforms.

Core Features & Use Cases

  • Guided design: Walks through naming, description, and scope to produce a clean SKILL.md.
  • Cross-platform portability: Ensures skills conform to the Agent Skills spec for use across Claude Code, Gemini CLI, Cursor, etc.
  • Scaffolding: Generates SKILL.md and optional references, scripts, and assets to accelerate skill creation.

Quick Start

Describe the skill you want, and I will scaffold a portable skill with frontmatter and starter files.

FAQPage Schema
How do I create portable agent skills that work across multiple platforms?

To create portable agent skills, you need to design them per the Agent Skills spec to ensure cross-agent compatibility. This involves generating a standardized SKILL.md scaffold with proper frontmatter and documentation for use across platforms like Claude Code, Gemini CLI, and Cursor.

What is a SKILL.md scaffold and why is it needed for agent development?

A SKILL.md scaffold is a standardized starter file structure that defines agent skill metadata, scope, and documentation. It is needed to ensure consistent discovery and portability, allowing a single skill to function seamlessly across different AI agents.

Can I use the same agent skill across Claude Code, Gemini CLI, and Cursor?

Yes, you can use the same agent skill across Claude Code, Gemini CLI, and Cursor. The Skill ensures cross-platform portability by conforming to the Agent Skills spec, validating that your documentation and starter files meet project conventions for each environment.

What is the best way to document agent skills for consistent discovery?

The best way to document agent skills for consistent discovery is through a guided design process that walks through naming, description, and scope. This produces a clean SKILL.md file with proper frontmatter, ensuring the skill is easily found and reused across agents.

Does scaffolding an agent skill include generating optional references and scripts?

Yes, scaffolding an agent skill includes generating optional references, scripts, and assets alongside the core SKILL.md file. This accelerates skill creation by providing all necessary starter files to meet project conventions and ensure cross-platform portability.

Why does my agent skill fail to port correctly between different AI platforms?

Agent skills fail to port correctly between platforms due to non-compliance with the Agent Skills spec. Inconsistent frontmatter, missing documentation, or fragmented scope definitions prevent cross-agent usage, requiring a standardized scaffold to ensure portability.
