Score: 6.7/10 (Innovation: 7, Technical: 6, Documentation: 4, Utility: 7)

Handler is an AI IDE that integrates with Codex and OpenCode, requiring every agent edit to include an explanation and allowing developers to question changes in a side chat without derailing the main agent. It also enables the agent to read the terminal, switch models without losing context, and supports isolated worktrees for concurrent agents. This project is interesting because it addresses the 'black box' problem in AI-assisted coding by enforcing reviewability and context isolation.

Target audience: backend devs, frontend devs, devops
