SEC438 / MD-GIT-RESET-ALLOWED-TOOLS ​

SEC438 flags AI-native markdown frontmatter when allowed-tools grants the exact token Bash(git reset:*).

Why It Matters ​

Blanket git reset authority lets an agent rewrite staged or working-tree state as part of a default shared policy. In AI-native instruction frontmatter, that is much 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 reset:*)

Clean Cases ​

These stay clean:

  • more specific reviewed commands such as Bash(git reset --hard HEAD~1)
  • frontmatter that does not grant git reset
  • fixture-like examples under test or fixture paths

Example Trigger ​

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

Safer Example ​

md
---
allowed-tools:
  - Bash(git reset --hard HEAD~1)
  - Read
---

How To Fix ​

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