reorganize_board
Restructure the WHOLE board into named groups at once. This is the one destructive action: it moves every note you list, so the human is asked to approve it first and may decline. Give a short rationale — they will read it before deciding. Prefer arrange_region for anything smaller than a full restructure.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
rationale |
string | yes | One sentence on why this structure is better. Shown to the human. |
groups |
array | yes | The groups to build, laid out left to right. |
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. |
