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

SECRETS_PATH_CREDENTIAL

Why this grade

  • SECRETS_PATH_CREDENTIAL Medium

    Mentions a credential store path (~/.ssh, id_rsa, .npmrc, .aws/credentials, credentials.json, .netrc).

    src/finops/ambient.py, line 4 which resolves the whole default chain: env vars, ~/.aws/credentials, named

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.

  • Install and update

    Note

    README documents an installer that pipes a download into a shell.

    Requires Python 3.11+. Need `uv`? `curl -LsSf https://astral.sh/uv/install.sh | sh` (or `brew install uv`).

  • Network

    Concern

    can reach a host that is not written as a fixed address. can reach api.github.com. The description does not name that host. can reach evil. The description does not name that host.
