Skill tags must be an array of strings

Error

Rule Details ​

The tags frontmatter field helps categorize and discover skills. When present, it must be a YAML array of strings. This rule delegates to the skill frontmatter Zod schema for validation, reporting the first schema violation found. Invalid tag formats prevent proper skill indexing and search functionality.

Incorrect ​

Tags as a single string instead of an array

yaml
---
name: deploy-app
tags: deployment
---

Tags array containing non-string values

yaml
---
name: deploy-app
tags:
  - deployment
  - 123
---

Correct ​

Valid tags array

yaml
---
name: deploy-app
tags:
  - deployment
  - ci-cd
  - production
---

No tags field (tags are optional)

yaml
---
name: deploy-app
description: Deploys the application
---

How To Fix ​

Ensure the tags field is a YAML array of strings. Each tag should be on its own line prefixed with -. Remove any non-string values from the array.

Options ​
