Run yield math in the CLI

You don't need a browser to run your numbers. `calculate_cd_yield` computes your growth directly in the terminal, which is perfect for your scripts or CI/CD pipelines. It keeps your workflow fast and headless. Just feed it the terms and grab the output.

Fetch benchmarks for your scripts

Need to check current rates on the fly? `fetch_market_benchmarks` pulls the latest numbers so you can integrate them into your own financial tools. It’s a clean way to keep your data current. No manual lookups required.

Your terminal can handle the heavy comparison work. The `generate_investment_comparison` tool outputs a structured breakdown of your CD versus the market. It’s built for automation. Use the result to trigger your next move.
