SEC506 / MD-GH-ISSUE-CREATE-ALLOWED-TOOLS ​

SEC506 flags AI-native markdown frontmatter when allowed-tools grants the exact token Bash(gh issue create:*).

Why It Matters ​

gh issue create mutates remote issue trackers. Shared frontmatter should not quietly make issue creation a default capability for every agent that loads the file.

Trigger Shape ​

The rule triggers only when all of these are true:

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

Clean Cases ​

These stay clean:

  • more specific read-only issue commands such as Bash(gh issue view:*)
  • frontmatter without Bash(gh issue create:*)
  • fixture-like examples under test or fixture paths

Example Trigger ​

yaml
allowed-tools:
  - Bash(gh issue create:*)
  - Read

Safer Example ​

yaml
allowed-tools:
  - Bash(gh issue view:*)
  - Read

How To Fix ​

Replace Bash(gh issue create:*) with a narrower reviewed command, or remove shared issue-creation authority from the frontmatter entirely.
