version: "1.0.0" name: current-sheet description: Use this skill to find out which workbook, sheet, and cell the user is currently looking at in the open-sheet viewer, so an instruction like "make this bold" or "why is this wrong?" resolves to the right place without asking. Use it whenever the user refers to "this cell", "this sheet", "the one I'm looking at", or gives an instruction with no explicit workbook id.

Resolve "this one"

The dev server publishes the reader's position to node_modules/.open-sheet/current.json as they navigate:

{ "id": "fy26-budget", "sheet": "P&L", "cell": "B7", "updatedAt": "2026-08-18T…" }

Read that file, or GET http://localhost:5373/__open-sheet/api/current.

Using it

1. Read the file. If it is missing or updatedAt is old, the dev server is

probably not running — ask which workbook rather than guessing.

1. id gives you sheets/<id>/index.tsx.
2. cell is an A1 address for reading only. It tells you where the user is

pointing; it is not something to write into the source.

Turning a cell into a source location

The user points at a cell; you have to edit the block that produced it. Open the workbook and work out which block covers that address — usually obvious from the sheet's structure — then change the authoring construct:

Never respond by writing an address into the file. If you find yourself wanting to, re-read sheet-authoring.
