Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

PERMISSION_DELETE_FILES INSTALL_UNPINNED NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    recipe-tools.ts, line 258 try { fs.unlinkSync(pendingPath); } catch { /* ok */ }

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    package.json, line 50 @modelcontextprotocol/sdk

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    compound-tools.ts, line 976 const response = await fetch(`${baseUrl}/api/v1/approvals`, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    RECIPE-SPEC.md, line 142 Variables use `{{name}}` syntax in agent.md and workflow files. When importing a recipe, the CLI prompts for each variable. Values are saved to a local `.env.recipe` file (gitignor

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
