Add it in the Muse app as a custom connector. It exposes 1 action: calculate_tip.

Muse Code made 26 tool calls and 8 edits across 8 files (+437 −21).
npm run verify passed on the first try.
Screenshot judge: pass. Final screen shows tip and total for $38.75 at 18 percent as $6.98 and $45.73 with correct rounding.
Built in 6 min for about $0.02 in model calls (est.).
