Show HN: Hi-shell – type commands in English, get ghost text in zsh (github.com)

A new tool called hi-shell has been introduced, streamlining the process of generating shell commands from natural language input directly within the zsh terminal. This AI-powered enhancement allows users to type out commands in English, which are then translated into shell commands displayed as ghost text in the command line. Users can review, edit, and approve these suggestions before executing them, thus maintaining control and incorporating a safety net with risk scoring for command suggestions. This tool is significant for the AI/ML community as it bridges the gap between human language and machine commands, improving accessibility for those less familiar with shell syntax. It operates as a seamless extension of the terminal workflow without creating a separate interface, prioritizing user interaction and command verification. Built-in safety features include the blocking of risky commands, like "rm -rf /," and support for configurations through OpenAI and DeepSeek APIs. The implementation process is straightforward, with a focus on maintaining environment security by storing sensitive API keys in environment variables rather than in configuration files.
