name	cairo-oracles
description	Explain Cairo oracles for offloading computation in executables, oracle::invoke, and constraints for soundness; use when a request involves experimental oracles or external computation in Cairo.

Cairo Oracles

Overview

Explain how to offload computations to external oracles in Cairo executables and constrain results.

Quick Use

• Read references/oracles.md before answering.
• Emphasize oracles are experimental and not available in Starknet contracts.
• Always show constraints that validate oracle outputs.

Response Checklist

• Use oracle::invoke(connection, selector, inputs) returning oracle::Result<T>.
• Connection strings typically use stdio: to spawn a process.
• Assert constraints immediately after oracle calls.
• Run executables with scarb execute --experimental-oracles.

Example Requests

• "How do I call an oracle from Cairo?"
• "Why must I validate oracle outputs?"
• "Can oracles be used in Starknet contracts?"
