D06 P01 Self Improve

Agent-neutral self-improvement loop: log correction moments, auto-apply rules on recurrence, grow skills and guarded scripts, mine session transcripts.

Compatibility: Not stated.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

PERMISSION_DELETE_FILES SECRETS_PATH_DOTENV

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    server/lib/skills.js, line 15 fs.rmSync(dst, { recursive: true, force: true });

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 5 .env

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.
