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 NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    plugins/tab-chord-formatter/skills/tab-formatting/scripts/format-tab.py, line 245 subprocess.run(

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    plugins/app-website-evaluator/skills/app-evaluation/SKILL.md, line 38 "$S" --url https://example.com # live fetch (needs curl): headers, HTTPS, robots/sitemap, perf

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    plugins/app-website-evaluator/skills/app-evaluation/SKILL.md, line 38 "$S" --url https://example.com # live fetch (needs curl): headers, HTTPS, robots/sitemap, perf

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    plugins/app-website-evaluator/skills/app-evaluation/reference.md, line 56 - No leaked secrets, `.env`, `.git/`, source maps, or stack traces in production.

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    tests/run-tests.sh, line 1 #!/usr/bin/env 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

    Concern

    can delete files.

    PERMISSION_DELETE_FILES

    plugins/tab-chord-formatter/skills/tab-formatting/scripts/format-tab.py, line 245

    subprocess.run(

    plugins/tab-chord-formatter/skills/tab-formatting/scripts/format-tab.py, line 258

    shutil.rmtree(profile, ignore_errors=True)

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Concern

    can reach a host that is not written as a fixed address. can reach api.github.com. The description does not name that host.
