Hi @wjquigsAZ - Thank you for the contribution! I believe it would be better suited in the 02-samples/ directory rather than its current location in 01-tutorials/01-fundamentals/04-tools/. Since this is a use-case driven sample (data analyst assistant) rather than a Strands feature tutorial.

Could you please move this to 02-samples/14-data-analyst-pandas/ and position it as a "Data Analyst Assistant with Context Efficiency Pattern"?

This placement would help users discover it when searching for data analyst use cases and better reflect that this is a complete working application, not just a feature tutorial. Also, please make sure to follow the template when you are moving the tutorial - https://github.com/strands-agents/samples/tree/main/.github/templates/02-samples
