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

Rescanned at commit 0cadb81e965d, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/check_openapi_drift.py, line 258 resp = httpx.get(spec_url, timeout=15.0)

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    AGENTS.md, line 37 config.py Settings (env/.env). Safety default: KALSHI_ENV=demo.

  • PERMISSION_SHELL_DECLARED Note

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

    scripts/smoke_test_uvx.py, line 42 def _send(proc: subprocess.Popen[str], message: dict[str, object]) -> None:

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    uv.lock, line 1 version = 1

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.
