A self-contained agentic development harness for Claude Code.

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 77532682f27f, unchanged since the check below.

OBFUSCATION_ENCODED_BLOB OBFUSCATION_MINIFIED_PAYLOAD

Why this grade

  • OBFUSCATION_ENCODED_BLOB Medium

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

    skills/explainme/assets/template.html, line 1 <!DOCTYPE html>

  • OBFUSCATION_MINIFIED_PAYLOAD Medium

    Contains a very long line with almost no spaces in a script or style file.

    skills/explainme/assets/template.html, line 1 <!DOCTYPE html>

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.
