Description

This introduces a Claude sub-agent for assisting users in setting up their local development environment in accordance with our Tilt configuration. It will walk users through each step of installing the necessary tools if they're missing, making any necessary configuration changes for their OS, and running the Tilt server. It could be a useful tool for new contributors or for seasoned contributors who run into issues with their local development environment.

By committing this sub-agent configuration to the repository, any local user's Claude installation should automatically suggest using this sub-agent if the user asks about running the project locally.
