Claude Code, Skill
Agent Toolkit
Personal agent toolkit: individually installable skills for Claude Code and Codex.
Compatibility: Not stated.
Grade C
One Medium finding. Read the report before installing.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
INSTALL_REMOTE_SCRIPT
Why this grade
- INSTALL_REMOTE_SCRIPT Medium
Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).
.github/workflows/validate.yml, line 18
curl -fsSL https://claude.ai/install.sh | bash
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
Plain notes from the hygiene checks.
Permissions
Pass
No shell or command call was found in the code. This check does not read permissions an entry declares. A permission line to run shell commands, including GitHub CLI (gh) commands and write or edit files was found in this repository, and it may apply to this entry.
Install and update
Serious
install fetches a script from the network.
