SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The Create Skill workflow standardizes the process of scaffolding reusable skill packages by authoring SKILL.md, generating starter evaluation templates, and wiring basic validation, so agents can discover and apply skills across runtimes without manual setup.

Core Features & Use Cases

  • Scaffolds a minimal SKILL.md surface plus starter evaluation templates to bootstrap a reusable skill.
  • Generates a portable directory structure including references/, scripts/, assets/, and evals/ for cross-runtime compatibility.
  • Validates frontmatter, links, and evaluation scaffolds to ensure portability and discoverability across runtimes.

Quick Start

Run the scaffold script with a skill name to generate a new skill folder containing SKILL.md and starter evaluation templates.

FAQPage Schema
How do I scaffold a reusable skill package for cross-runtime use?

Scaffolding a reusable skill package requires authoring a SKILL.md file and generating starter eval resources. This creates a minimal, portable directory structure with references, scripts, assets, and evals to enable cross-runtime discovery.

What is SKILL.md authoring and why do I need frontmatter validation?

SKILL.md authoring defines the skill interface for agents to discover and apply. Frontmatter validation ensures portability and discoverability across runtimes by verifying metadata, links, and evaluation scaffolds meet structural requirements.

Can I use skill templates to generate starter evaluation resources automatically?

Yes, skill templates can generate starter evaluation resources automatically. The scaffold script creates a new skill folder containing SKILL.md and starter evaluation templates to bootstrap a reusable skill package quickly.

Does the skill scaffold include an agent manifest for deployment?

No, the skill scaffold omits agent manifest creation. It focuses on producing a minimal, portable structure with SKILL.md, frontmatter validation, optional references, scripts, assets, and starter evals for quick cross-runtime deployment.

What's the best way to structure references, scripts, and assets for cross-runtime compatibility?

The best way to structure resources for cross-runtime compatibility is using a portable directory layout. Organize files into references, scripts, and assets folders alongside SKILL.md and evals to ensure agents can discover and apply skills across runtimes.

When do I need to create a skill scaffold instead of manually setting up a skill package?

You need a skill scaffold when standardizing reusable skill packages across multiple runtimes. It automates SKILL.md authoring, directory generation, and validation to eliminate manual setup errors and ensure consistent portability and discoverability.
