SEC435 / MD-GIT-CONFIG-ALLOWED-TOOLS ​

SEC435 flags AI-native markdown frontmatter when allowed-tools grants the exact token Bash(git config:*).

Why It Matters ​

Blanket git config authority lets an agent rewrite repository or user git configuration as part of default shared policy. In AI-native instruction frontmatter, that is harder to review than a narrow workflow-specific command.

Trigger Shape ​

The rule triggers only when all of these are true:

  • the file is an AI-native markdown instruction surface with parsed frontmatter
  • the path is not fixture-like
  • allowed-tools or allowed_tools contains the exact token Bash(git config:*)

Clean Cases ​

These stay clean:

  • more specific reviewed commands such as Bash(git config user.name belief)
  • frontmatter that does not grant git config
  • fixture-like examples under test or fixture paths

Example Trigger ​

md
---
allowed-tools:
  - Bash(git config:*)
  - Read
---

Safer Example ​

md
---
allowed-tools:
  - Bash(git config user.name belief)
  - Read
---

How To Fix ​

Replace Bash(git config:*) with a narrower reviewed command pattern, or remove broad git configuration authority from shared frontmatter entirely.
