Graduation rationale

Checks AI-native frontmatter for exact `Glob(*)` grants that expose unconstrained file discovery as shared default policy.

SEC523 / MD-GLOB-WILDCARD ​

SEC523 flags AI-native markdown frontmatter when allowed-tools or allowed_tools contains the exact wildcard token Glob(*).

Why It Matters ​

Glob(*) grants broad file-discovery authority. In shared AI-native frontmatter, reviewed repo-local discovery patterns are a much safer default than global wildcard discovery.

Trigger Shape ​

  • AI-native markdown surface with parsed frontmatter
  • path is not fixture-like
  • allowed-tools or allowed_tools contains the exact token Glob(*)
