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?"
