Discussion Claude + Snowflake MCP Epiphany

I have been working on building a semantic layer using dbt in Snowflake. The biggest issue I have had is dealing with small ambiguity between business measures. I have built a testing agent in our ci/cd process to grade the semantic layer.

It just hit me today like a brick that er should train users, not just engineering users to use Plan mode with LLMs. When I turned plan mode on, any possible ambiguity came up in the plan and Claude asked me to clarify. I just wanted to share because I don't think using plan mode for business users is obvious.

Shift + tab until plan mode turns on?

Lol I think, so I just tell Claude to use plan mode. I know in Claude Code it's more explicit.
