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

Rescanned at commit ec783a069ea2, unchanged since the check below.

SECRETS_PATH_UNCONFIRMED OBFUSCATION_ENCODED_BLOB PERMISSION_SHELL_DECLARED

Why this grade

  • SECRETS_PATH_UNCONFIRMED Low

    The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.

    .gitignore, line 27 # env file

  • OBFUSCATION_ENCODED_BLOB Low

    Contains a long base64 shaped string in a file that should be readable.

    testdata/invalid-compatibility-too-long/SKILL.md, line 4 compatibility: ccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccc

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    cmd/sklint/main_test.go, line 17 cmd := exec.Command(os.Args[0], "-test.run=TestExitWithError")

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.
