Graded by PlugVetRubric v2

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

Rescanned at commit 9a0e3c6e3b8f, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    bin/cold-shower.js, line 91 try { fs.rmSync(SKILLS_DIR, { recursive: true }) } catch {}

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    skills/cold-shower/references/audits.md, line 223 gzip=$(curl -s "https://bundlephobia.com/api/size?package=${pkgver}" \

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    benchmarks/bench.js, line 99 if (!gitignore.includes('.env')) issues.push('.env not in .gitignore')

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    README.md, line 61 curl -fsSL https://raw.githubusercontent.com/PradiptaPutra/cold-shower/main/install.sh | bash

  • SECRETS_ENV_READ Note

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

    skills/cold-shower/references/sprints.md, line 86 token: process.env.UPSTASH_VECTOR_REST_TOKEN!,

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.
