# Prompt to Claude Code

I would like to build a Streamlit app to optimize one of our internal business processes.

I have already compiled a comprehensive plan for the project, available at @plan.md. Please thoroughly review the plan and, while sticking to the original plan, come up with your own plan on how to implement it. Highlighting any gaps in the plan and proposing your own solutions for them.

The @plan.md file references a few external files. You can find them in the @./graphql-publishing and @publishing_files folders. Please make sure to read them while evaluating the plan from @plan.md
