Bog-standard LLM mapping is terrible and I recently added Google Maps to my personal agent to remediate this.

I'd love to try Voygr for fun. Is there a skill defined that I could just swap in Voygr

Google also doesn't tell you if a place exists - it just returns the list of possible places which it thinks could be relevant. We have instructions defined for agents to onboard https://github.com/voygr-tech/dev-tools
