Graded by PlugVetRubric v2

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

Rescanned at commit b739a8af570e.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    skills/brainstorming/scripts/server.cjs, line 604 if (fs.existsSync(eventsFile)) fs.unlinkSync(eventsFile);

  • NETWORK_NO_FIXED_HOST Low

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

    skills/brainstorming/scripts/helper.js, line 80 ws = new WebSocket(websocketUrl());

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    docs/superpowers/plans/2026-05-06-lift-drill-into-evals.md, line 106 --exclude=.env \

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    skills/brainstorming/scripts/server.cjs, line 123 const TOKEN_FILE = process.env.BRAINSTORM_TOKEN_FILE || null;

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.
