Execution Context Logger

A utility that demonstrates the difference between local and remote execution in Modal by logging execution context information.

Capabilities

Context Detection

Write a program that uses Modal execution context functions to detect and log whether code is running in a local or remote environment. The program should run a simple function both locally and remotely, logging execution details.

• When run locally using the local entrypoint, it prints "Running in local context" @test
• When the Modal function executes remotely, it logs the function call ID and input ID @test
• The local entrypoint invokes the remote function and displays its return value @test
