What it does

When installed, this skill teaches the agent the conventions for making new agent skills: how to write a concise SKILL.md with a name and description, when to add optional scripts, references, or assets folders, and how to keep instructions focused. It also includes helper scripts that create a skill folder from a template, generate an agents/openai.yaml UI metadata file, and run a quick check that the SKILL.md frontmatter is valid.

Great for

  • Developers who want the agent to scaffold a new skill folder quickly
  • Teams maintaining a library of skills who want consistent structure and validation
  • People learning how skills are organized before writing their own

Skip it if

  • Ordinary coding or writing tasks, since it only adds value when the goal is building a skill (it may route poorly if loaded for unrelated work)
  • Users who do not want scripts run on their machine, because the helper scripts are Python files the agent can execute to create and validate files

Try asking

  • “Create a new skill called pdf-form-filler with a scripts folder for the form logic”
  • “Update the existing skill in my repo so its description is more specific”
  • “Validate the SKILL.md frontmatter in my skill folder before I publish it”
  • “Generate an agents/openai.yaml file for my skill with a display name and short description”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Review the generated folder and SKILL.md before relying on it, since the templates contain TODO placeholders that must be replaced.
  • Ask for only the resource folders you need (scripts, references, assets) to keep the skill lean.
  • Run the validation script after every change to catch frontmatter errors early.
