summarize_cluster
Collapse a group of notes into a single labelled summary note in the same place on the canvas. The originals gather to the centre and are replaced; edges to the outside world are rewired to the summary. Use this to reduce a solved area of the board to one idea.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
nodeIds |
array | yes | Ids of the notes to collapse. |
summary |
string | yes | The text of the resulting summary note. |
basedOn |
number | no | The `asOf` you were given by the get_scene this plan is based on. Cite it and the page will refuse this call outright rather than let it overwrite anything another participant changed while you were deciding. Omitting it is allowed and skips the check; you are then writing blind. |
