Universal Example Skill

This Skill demonstrates how to write platform-agnostic content using the template engine.

Platform Information

Platform: Claude Code

This is the optimized version for Codex with concise documentation. Codex has a 500-character description limit, so this version is streamlined.

Common Features

These features work on both platforms:

Feature 1: Code Generation

function generateCode() {
  return 'Generated code works everywhere!'
}

Feature 2: Template Support

Both platforms support the same template structure.

Feature 3: Resource Management

Assets and references work consistently across platforms.

    const transformed = this.transform(validated)
    return this.output(transformed)
  }
