📘 ExplainedVistaar se

You describe tools with names and JSON schemas; the model replies with a tool call and arguments; your code validates them, runs the tool and returns the result; the model continues. The model never runs code itself. Keep tools small and clear, check permissions and require confirmation for risky actions.Tools ko naam aur JSON schemas se describe karte ho; model tool call aur arguments ke saath jawaab deta hai; aapka code unhe validate karta, tool chalata aur result lautata hai; model aage badhta hai. Model khud kabhi code nahi chalata. Tools chhote aur saaf rakho, permissions check karo aur risky actions pe confirmation maango.

💡 Real exampleAsli example

The user asks 'where is order 4512?' and the model calls get_order_status(4512).User poochhta hai 'order 4512 kahan hai?' aur model get_order_status(4512) call karta hai.
