  • how_to_joinHow a person joins the lab and lends their coding agent's time.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    How a person joins the lab and lends their coding agent's time. Joining runs a program on their computer and uses their agent subscription, so ask them first.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
