Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming — see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps — measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Driving Apple Numbers with background computer use
Use these rules in addition to the main computer-use skill:
- Always call
get_app_state app="Numbers"before interacting. - A single
clickselects a cell; double-click orpress_key key="Return"
enters edit mode. Triple-click selects the cell's existing value.
- Use
Tab/shift+Tab/Return/shift+Returnto move between cells —
never embed those as literal characters in type_text.
- Prefer
set_valueon Format-inspector numeric inputs (settable=true). - For multi-cell selection, use
dragfrom the top-left cell to the
bottom-right cell.
- Always re-call
get_app_stateafter switching sheets — the entire tree
changes.
Detailed behavior lives in server/app-hints/Numbers.md, which is injected into ` on every getappstate` call for Numbers.
