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

Rescanned at commit 55d41b9936dc, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    skill/SKILL.md, line 36 curl -s -X POST https://www.pentagonal.ai/api/fetch-contract \

  • SECRETS_ENV_READ Note

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

    test-mcp.mjs, line 213 if (process.env.ANTHROPIC_API_KEY) {

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.
