REFERENCE/TOOLKITS/TRELLO.MD

Trello

Boards, lists, and cards. Create and organize them, manage checklists, labels, members, and comments, and search a workspace.

Measured routing accuracy

73 golden cases replayed through the router over the whole index: measured over corpus ea4f12ad2948 (65 toolkits, 2283 tools indexed and 13 declared uncallable), 40 cases written by hand and 33 cases from the paraphrase pass. A case counts as top-1 when its gold tool ranked first and top-8 when it reached the slate at all.

MeasureCasesShare
top-125/7334.2%
top-855/7375.3%

The sweep is offline: the reranker is a deterministic identity fake that returns candidates in the order retrieval produced them, so top-1 measures retrieval order rather than a reranked slate. just eval-live measures the same cases through the live reranker.

Authentication

Connect an entity with ConnectionsService.InitiateConnection, naming this toolkit's slug. Credentials stay in the connections vault; callers hold connected-account ids only.

api_key

PropertyValue
Placementquery
Nametoken
Rendered as{key}

Submit the key with ConnectionsService rather than putting it in a request; it is sealed at rest and never returned.

Tools

40 action tools. The catalog-wide slug is trello.<tool>, which is what search_tools returns and call_tool takes.
