Tool execution
-
The AI sends tool calls as JavaScript blocks (cuckoo). Each one is intercepted, shown in the overlay and run in a Node sandbox. Failures are highlighted in red.

-
view_agenda
-
Inline tool blocks
-
Every cuckoo block turns into a collapsible card with an icon, the tool name and a file hint taken from the first argument.

Every AI reply gets a badge: ⏱ 5.2s · ~380 tok. Real stream time and an approximate token estimate.
