description	Explain Starknet library calls that execute code from another class using class hash; use when a request involves library dispatchers, class hashes, or library_call_syscall.

Cairo Library Calls

Overview

Explain how to execute code from another class in the caller context using library calls.

Quick Use

• Read references/library-calls.md before answering.
• Distinguish contract calls from library calls (context and storage).
• Use a LibraryDispatcher with a class hash when possible.

Response Checklist

• Use library calls when you need to reuse logic without deploying another instance.
• Mention that library calls run in the caller's storage context.
• Use Serde for calldata and return data when using low-level syscalls.

Example Requests

• "How do I call a class by hash from a contract?"
• "What is the difference between library_call and contract_call?"
• "How do I use library_call_syscall directly?"
