Grades are a hygiene check, not a security guarantee.

Security scanner and runtime protection for AI coding agents.

Compatibility: Not stated.

Grade D

Two or more Medium findings, or a High finding. Only try it in a sandbox.

Graded by PlugVetRubric v2

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

Rescanned at commit 06cbad1281e9.

AGENT_IGNORE_INSTRUCTIONS SECRETS_PATH_CREDENTIAL OBFUSCATION_ENCODED_BLOB

Why this grade

  • AGENT_IGNORE_INSTRUCTIONS High

    Text tells the agent to ignore earlier instructions.

    .claude/skills/qa-dashboard/SKILL.md, line 26 3. **Playground**: scan a harmless text and a text containing `IGNORE ALL PREVIOUS INSTRUCTIONS` (Playground scans do not use quota). Is the result understandable and localized?

  • SECRETS_PATH_CREDENTIAL Medium

    Mentions a credential store path (~/.ssh, id_rsa, .npmrc, .aws/credentials, credentials.json, .netrc).

    qa/hooks.mjs, line 252 if (!existsSync(join(qaData, 'auth/credentials.json'))) {

  • OBFUSCATION_ENCODED_BLOB Medium

    Contains a long base64 shaped string in a file that should be readable.

    plugins/automations/n8n/package-lock.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.

If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Note

    requests shell access. The manifest names this permission.

  • Install and update

    Note

    The docs document an installer that pipes a download into a shell.

    Concern

    can reach a host that is not written as a fixed address. can reach api.github.com. The description does not name that host.
