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

Rescanned at commit 8ea68cc946eb, unchanged since the check below.

PERMISSION_DELETE_FILES INSTALL_UNPINNED SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    scripts/probe_acp_agents.py, line 533 shutil.rmtree(tmpdir, ignore_errors=True)

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    README.md, line 133 curl -LsSf https://astral.sh/uv/install.sh | sh

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/probes/probe_hermes.py, line 6 Auth: inherits from ~/.hermes/config.yaml / ~/.hermes/.env (no ACP auth methods)

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    README.md, line 133 curl -LsSf https://astral.sh/uv/install.sh | sh

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.

What was checked
