Graduation rationale

Checks AI-native frontmatter for `Edit(...)` grants scoped to absolute, home-relative, drive-letter, or parent-traversing paths outside the repository boundary.

Deterministic signal basis

MarkdownSignals exact frontmatter token analysis for `Edit(...)` scopes with absolute, home-relative, drive-letter, or parent-traversing path markers.

SEC430 / MD-EDIT-UNSAFE-PATH ​

SEC430 flags AI-native markdown frontmatter when allowed-tools or allowed_tools grants Edit(...) over an absolute path, home-relative path, Windows drive path, or parent-traversing path.

Why It Matters ​

Shared instruction frontmatter should not silently authorize edits outside the repository scope. Repo-external or parent-traversing Edit(...) grants weaken reviewability and make workspace boundaries unclear.

Trigger Shape ​

  • AI-native markdown surface with parsed frontmatter
  • path is not fixture-like
  • allowed-tools or allowed_tools contains Edit(...)
  • the inner path starts with /, ~/, ~\\, a Windows drive prefix, or contains ../ or ..\\

Clean Cases ​

  • repo-local scopes such as Edit(./docs/**)
  • frontmatter without Edit(...)
  • fixture-like examples under test or fixture paths

Example Trigger ​

md
---
allowed-tools: Edit(~/workspace/**), Read(./docs/**)
---

Safer Example ​

md
---
allowed-tools: Edit(./docs/**), Read(./docs/**)
---

How To Fix ​

Replace repo-external Edit(...) grants with narrower repo-local scopes, or remove shared edit authority outside the project boundary.
