Grade B

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

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP OBFUSCATION_FILE_CAP_REACHED

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    benchmarks/lib/kernel-adapter.js, line 444 try { fs.unlinkSync(this.dbPath); } catch {}

  • NETWORK_NO_FIXED_HOST Low

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

    benchmarks/e2e-qa.js, line 52 console.log(' curl -fsSL -o /tmp/longmemeval-data/longmemeval_s_cleaned.json \\');

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    benchmarks/e2e-qa.js, line 52 console.log(' curl -fsSL -o /tmp/longmemeval-data/longmemeval_s_cleaned.json \\');

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/core/topic-detector.ts, line 27 { name: 'config', patterns: /\b(config|setting|environment|env|variable|dotenv|yaml|toml|json config|.env)\b/i },

  • SECRETS_ENV_READ Note

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

    dashboard/server/queries.js, line 580 result.available = !!process.env.ANTHROPIC_API_KEY;

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    benchmarks/results/e2e-qa-real-500q-FINAL.json, line 1 {

  • OBFUSCATION_FILE_CAP_REACHED Note

    The 400 file cap was reached before every file was read.

    benchmarks/results/e2e-qa-real-500q-FINAL.json, line 1 {

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.
