od-plugin-authoring (scenario)

Use this scenario when the user wants to create their own OpenDesign plugin.

Required outcome

Produce a folder named generated-plugin/ in the active project workspace. At minimum, the folder must contain:

• SKILL.md with frontmatter and clear agent instructions.
• open-design.json with valid plugin metadata, od.kind, mode, task kind, capabilities, and inputs when needed.

Add examples/, assets/, or other supporting files only when they help the plugin be used or reviewed.

Authoring rules

• Follow docs/plugins-spec.md and the schema at docs/schemas/open-design.plugin.v1.json.
• Treat SKILL.md as the canonical behavior description. open-design.json should describe how OpenDesign installs, applies, and presents that behavior.
• Keep the generated plugin local-user friendly: it should not require marketplace publishing, enterprise trust setup, or private team catalog configuration.
• Choose a stable plugin id from the user's requested workflow. Use lowercase letters, numbers, dashes, underscores, or dots.
• Include a short readiness summary when finished:
• Files created.
• Whether the folder is ready to add to My plugins.
• Any validation or follow-up needed before install.
• A direct next-action prompt that offers: Add to My plugins, Publish repo, or OpenDesign PR.

Suggested folder shape

generated-plugin/
  SKILL.md
  open-design.json
  examples/
  assets/

The examples/ and assets/ directories are optional. Do not create empty directories just to match the sketch.
