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

OBFUSCATION_ENCODED_BLOB PERMISSION_SHELL_DECLARED

Why this grade

  • OBFUSCATION_ENCODED_BLOB Low

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

    README.md, line 220 [![Oathe Security](https://img.shields.io/endpoint?url=https%3A%2F%2Faudit-engine.oathe.ai%2Fapi%2Fbadge%2Frebelytics%2Fone-skill-to-rule-them-all&style=for-the-badge&logo=data:ima

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    scripts/validate-skill-bundle.py, line 1191 r = subprocess.run(args, cwd=tmp, env=env, capture_output=True, text=True,

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.
