SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Creating reusable skills for Stella agents often requires guessing the correct folder structure, frontmatter format, and resource organization, leading to broken or undiscoverable skills that fail to work as intended. This skill eliminates that friction by providing a clear, step-by-step workflow to create and update skills that fully comply with Stella's structural and discovery requirements.

Core Features & Use Cases

  • Standardized Skill Creation: Guides users through Stella's required skill structure, including mandatory SKILL.md frontmatter with name and description fields, and optional resource directories for scripts, references, and assets.
  • Built-in Validation: Includes a lightweight validation script to check for frontmatter errors, naming rule violations, and structural issues before deploying a skill to Stella.
  • Use Case Example: If you want to build a skill that lets Stella generate weekly team status reports, use this skill to initialize the correct folder structure, template the SKILL.md content, and validate the skill is properly formatted for Stella's discovery system.

Quick Start

Use the skill-creator skill to build a new Stella skill for automating weekly team status report generation.

Why does my custom Stella skill fail to show up in the discovery system?
