We need a standardized Terraform module to install, configure and run Aider agent in Coder workspaces. The module should follow the implementation pattern of the Claude Code module, providing variables for agent configuration (version, install toggle, workspace folder), terminal multiplexer support (tmux/screen), and proper app integration via coder_app resource. Implementation should include installation scripts with pre/post hooks, environment configuration, and session persistence. The module will enable consistent Aider integration across different Coder environments with minimal configuration overhead.
