SEC518 / MD-GH-VARIABLE-DELETE-ALLOWED-TOOLS ​

SEC518 flags AI-native markdown frontmatter when allowed-tools grants blanket gh variable delete authority.

Why It Matters ​

gh variable delete can remove GitHub variables. In shared AI-native markdown guidance that is broader than most teams want to advertise as default agent authority.

Trigger Shape ​

  • the file is an AI-native markdown surface
  • the path is not fixture-like
  • frontmatter allowed-tools or allowed_tools contains the exact token Bash(gh variable delete:*)

Clean Cases ​

  • narrower read-only grants such as Bash(gh variable list:*)
  • markdown surfaces without blanket variable deletion grants
  • fixture-like examples under test or fixture paths

Example Trigger ​

yaml
---
allowed-tools:
  - Bash(gh variable delete:*)
---

Safer Example ​

yaml
---
allowed-tools:
  - Bash(gh variable list:*)
---

How To Fix ​

Remove shared gh variable delete tool grants or replace them with narrower reviewed commands that keep variable deletion under explicit user control.
