Score: 5.5/10 (Innovation: 5, Technical: 5, Documentation: 8, Utility: 4)

agenttab is a shell-based utility that displays AI agent status (busy, idle, waiting) as icons in terminal tab titles for Claude Code, Codex, and OpenCode. It integrates via hooks and a small plugin, polling session state files and process info to update the title. The project is well-documented but solves a narrow, environment-specific niche problem.

Target audience: developers using AI coding agents in terminal-based workflows
