Graded by PlugVetRubric v2

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

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST OBFUSCATION_ENCODED_BLOB PERMISSION_SHELL_DECLARED SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    skills/backtest/scripts/trader.py, line 80 with urllib.request.urlopen(req, timeout=60) as r:

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    skills/backtest/scripts/trader.py, line 80 with urllib.request.urlopen(req, timeout=60) as r:

  • OBFUSCATION_ENCODED_BLOB Low

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

    assets/readme/hero-dark.svg, line 1 <svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="800" height="360" viewBox="0 0 800 360">

  • PERMISSION_SHELL_DECLARED Note

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

    skills/backtest/engine/crates/py/python/oxarchive_backtest/cli.py, line 224 subprocess.Popen([*base, "--shard", f"{i}/{workers}"], stdout=subprocess.PIPE, text=True)

  • SECRETS_ENV_READ Note

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

    skills/backtest/engine/crates/py/python/oxarchive_backtest/cli.py, line 402 if not (os.environ.get("OXARCHIVE_API_KEY") or os.environ.get("OXA_API_KEY")):

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

    Note

    requests shell access. The manifest names this permission.

    PERMISSION_SHELL_DECLARED

    skills/backtest/engine/crates/py/python/oxarchive_backtest/cli.py, line 224

    subprocess.Popen([*base, "--shard", f"{i}/{workers}"], stdout=subprocess.PIPE, text=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.0xarchive.io. The description does not name that host.

    NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST
