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

Rescanned at commit e5fdc319bfae, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    code-mode-cli/src/oauth.ts, line 121 const res = await fetch(url, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    code-mode-cli/SKILL.md, line 37 { "variable_loader_type": "dotenv", "env_file_path": ".env" }

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.
