SEC526 / MD-WEBSEARCH-WILDCARD ​

SEC526 flags AI-native markdown frontmatter when allowed-tools or allowed_tools contains the exact wildcard token WebSearch(*).

Why It Matters ​

WebSearch(*) makes open-ended search authority part of shared default policy. Reviewed domain- or query-scoped search grants are easier to reason about and safer to ship.

Trigger Shape ​

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

Safer Example ​
