One-line AI Shell Helper

One-line AI Shell Helper is a zsh shell function designed to streamline the process of obtaining concise AI-generated answers or shell commands directly from the terminal. It addresses the inefficiency of switching to a separate chat interface for quick command-line queries or factual lookups by integrating AI assistance into the command-line workflow.

The function operates by dispatching user queries to an AI CLI backend, returning either a one-line factual answer or a shell command. If the AI's response is identified as a runnable command, the function uses the print -z feature to pre-type the command into the next zsh prompt, allowing the user to review and execute it manually. Otherwise, it prints the result to standard output. This approach ensures that factual answers, such as mathematical results or definitions, are displayed directly, while suggested commands are queued safely for user approval before execution.

The tool employs a heuristic to distinguish between commands and non-command answers by checking if the first word of the response is a valid executable in the system's PATH and starts with a letter or underscore. Defensive measures, such as using 'noglob' on the alias and setting shell options locally within the function, help prevent unintended shell expansions and maintain predictable behavior regardless of user configuration.

Delivery is through a zsh function, which can be integrated into a user's shell environment. The AI backend is flexible, allowing users to substitute their preferred AI CLI tool.
