name: bad-allowed-tools description: Use when you need to test a skill with allowed-tools as a YAML list. allowed-tools: - Read - Write - Bash
The allowed-tools field must be a space-delimited string, not a YAML list.
Correct format: allowed-tools: "Read Write Bash"
Wrong format: the YAML list above
Expected failure: frontmatter.allowed-tools-format [moderate]
