Grades are a hygiene check, not a security guarantee.

Regression memory for coding agents. (There's a CLI and CI mode too — but the agent loop is the point.)

Compatibility: Not stated.

Grade B

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

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

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.

    bench/lib/mutate.mjs, line 111 fs.rmSync(filePath, { force: true });

  • NETWORK_NO_FIXED_HOST Low

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

    src/suggest/ai/triage.ts, line 133 /** Override fetch (forwarded to callProposeTool). */

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 16 .env

  • SECRETS_ENV_READ Note

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

    bench/baselines/cosign/baseline.mjs, line 98 if (keyless && process.env.PROOFKIT_BENCH_COSIGN_KEYLESS !== '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.
