Purpose: This tool is a terminal user interface that acts as a sidebar for managing, monitoring, and quickly switching between tmux sessions.

Security Assessment: The application inherently executes shell commands to manage your tmux sessions and reads file statuses (like git branch information) to display in the UI. A significant security concern is found in the installation script, which contains a `rm -rf` recursive force deletion command. While common in uninstall or update steps, blind execution of remote scripts with force deletion capabilities requires caution. No hardcoded secrets or dangerous system permissions were detected, but users should inspect the script before running it. Overall risk: Medium.

Quality Assessment: The project is written in Rust and was updated very recently, indicating active maintenance. However, there are red flags regarding maturity and legal safety. It lacks a license file, meaning there are no explicit permissions for use, modification, or distribution. Additionally, with only 5 GitHub stars, it has very low community adoption and visibility.

Verdict: Use with caution — it is a helpful utility for tmux power users, but the missing license and risky install script mean you should review the code or build from source rather than piping the install script directly to your shell.
