Build a Tool-Backed Market Brief Copilot (Not a Chat Demo)

In a fintech or wealthtech product, people constantly need quick market context. Turn a stock question into a short, repeatable market brief. In Part 1, we’ll build the engine in copilot.py. A small set of EODHD-backed tools, an agent with strict rules, and a few demo runs. In part 2, we'll wrap it in a Streamlit MVP so you can type a query, get the brief, and see the tool-backed metrics.
