Just ask the agent naturally — it selects the right tool automatically.
Direct ticker lookup (agent skips stock_resolve, calls stock_profile directly):
What is Apple's current stock price?
Company name → symbol → profile (two-tool chain):
What sector is Nvidia in?
Agent calls stock_resolve("nvidia") → finds NVDA → calls stock_profile("NVDA").
Ambiguous name:
Look up Amazon stock
Get the SEC EDGAR filing link:
Give me the SEC EDGAR filing link for Microsoft
Agent calls stock_resolve("Microsoft") and surfaces the direct link to EDGAR filings.
Find multiple companies by name:
Find all companies with "apple" in the name
Returns up to 10 matches with ticker, CIK, and EDGAR link for each.
User: "What is Nvidia's current stock price?"
Agent:
1. stock_resolve("nvidia") → finds NVDA
2. stock_profile("NVDA") → returns live price + profile
