The Problem

Developers constantly copy commands from LLMs, Stack Overflow, or history but forget what the options mean. Reading man pages breaks flow, and existing tools are shell-specific or require leaving the terminal. This creates friction and risk when running unfamiliar commands.

Potential Solution

A lightweight daemon with cross-shell plugins that detects command tokens and displays contextual tooltips using man pages, community docs, and AI. Provides inline explanations in any terminal, plus team documentation sync for internal CLI tools.

Why Now?

LLMs are generating more CLI commands than ever, increasing the need for instant documentation. The developer tools market has proven willingness to pay for productivity gains (e.g., GitHub Copilot).

Improving Zsh vi-mode ergonomics with inline man-page lookups (zsh-vi-man)

r/programmingNov 28, 2025

I wrote a small extension called `zsh-vi-man` that hooks into Zsh’s line editor. When your cursor is on a command-line option, pressing Shift+K opens the relevant part of the man page. It’s similar to how Vim’s `K` works, but adapted for shell usage by identifying the token under the cursor and jumping to the matching section in the manual.
