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

INSTALL_REMOTE_SCRIPT AGENT_HIDDEN_STEP

Why this grade

  • INSTALL_REMOTE_SCRIPT High

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

    skills/flowleap/SKILL.md, line 68 curl -fsSL https://raw.githubusercontent.com/flowleap-ai/flowleap-cli/main/install.sh | sh

  • AGENT_HIDDEN_STEP High

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

    skills/flowleap-auth/SKILL.md, line 107 | `unverified` | 7 | The backend could not be reached, so validity is **unknown**. Retry later; do NOT tell the user their credential is invalid. |

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Pass

    Serious

  • Network

    Concern

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