Why this grade

  • AGENT_HIDDEN_STEP High

    Text tells the agent to hide a step or not to tell the user.

    opt/hatch/skills/muse-feedback/SKILL.md, line 162 a background retry, and do not tell the user you will make sure it lands.

  • INSTALL_REMOTE_SCRIPT Medium

    Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).

    opt/hatch-image/bin/npm-package/README.md, line 24 curl -qL https://www.npmjs.com/install.sh | sh

  • SECRETS_PATH_CREDENTIAL Medium

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

    opt/hatch-image/bin/npm-package/docs/content/commands/npm-install.md, line 289 GIT_SSH_COMMAND='ssh -i ~/.ssh/custom_ident' npm install git+ssh://[email protected]:npm/cli.git

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.

If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.

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.
