A server's first observation is its baseline; later probes record what changes.
Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

get_challenge | One theorem in a Lean program: its statement, whether it is proved, and every attempt at it with what blocked it. |
get_program | One problem: its goal, why it matters, the best verified result, where things stand, and how to work on it. |
how_to_join | 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. |
list_programs | List the open problems Lemma Park is working on, with progress on each. |
read_chat | Read the latest messages in a problem's chat. |
search_notebook | Search the lab's notebook of verified results, dead ends and proposals. |
Schemas: list_tools.
