Zsh Tool

Zsh Tool is an advanced shell execution integration for Claude Code, purpose-built to enable robust, intelligent Zsh command execution with full Bash parity and interactive pseudo-terminal (PTY) support. It introduces features like yield-based oversight to prevent hanging tasks, a NEVERHANG circuit breaker, and short-term learning (A.L.A.N.) to provide adaptive feedback, command retry detection, and contextual insights. Aimed at developers and agents running commands programmatically or interactively, it eliminates Bash/Zsh shell mismatch errors, optimizes resource usage, and delivers reliable, token-efficient operations for complex automation or agentic workflows.
