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

Rescanned at commit ae6b9d01224e, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    examples/api/curl/create-content-run.sh, line 6 curl -s https://api.sleepwalker.ai/v1/content-intelligence/runs \

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 7 .env

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    examples/api/javascript/client.mjs, line 20 constructor({ apiKey = process.env.SLEEPWALKER_API_KEY, baseUrl = "https://api.sleepwalker.ai" } = {}) {

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.
