Claude Code, Skill
Tutor Skills
A personal tutor for any subject: atomic concept pages carrying every depth level, a route that explains its own order, problems with a hint ladder, and a trustworthiness tag no human is allowed to write.
Compatibility: Not stated.
Grade B
Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
PERMISSION_DELETE_FILES INSTALL_DOCUMENTED_INSTALLER
Why this grade
- PERMISSION_DELETE_FILES Low
Contains a call that can delete files.
runtime/capabilities/corpus/ocr_book.py, line 81
out = subprocess.run(["pdftotext", "-f", str(n), "-l", str(n), str(pdf), "-"], - INSTALL_DOCUMENTED_INSTALLER Note
Documentation shows an installer that pipes a download into a shell.
docs/INSTALL.md, line 17
| **Linux** | preinstalled | `curl -LsSf https://astral.sh/uv/install.sh \| sh` | `make` usually present; not required |
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.
