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.
Rescanned at commit 2572d3557fc6, unchanged since the check below.
NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST PERMISSION_SHELL_DECLARED
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
codex/skills/adding-observability/examples.md, line 96
const response = await fetch(url, { headers }); - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
codex/skills/adding-observability/examples.md, line 96
const response = await fetch(url, { headers }); - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.
codex/skills/securing-llm-features/examples.md, line 63
result = subprocess.run(command, shell=True, 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.

- **Processes.** Call `subprocess.run([program, *args], check=True, timeout=...)`. The argument list never passes through a shell, while `shell=True` with input is shell injection.
