Years of Oh My Zsh for just 3-4 features, and a slow shell to show for it. Claude Code rebuilt those features into a single .zshrc, and the shell got much faster. Their other configs moved in minutes.
Result Moved to Lazy.nvim and Ghostty in minutes too
“In the end I ended up removing Oh My ZSH entirely, now I have a single .zshrc file that contains everything, and it became much faster.”

Had used Oh My Zsh for years but relied on only 3-4 features: autocompletion, the git plugin, history search and one theme. Asked Claude Code to make the slow shell faster, and ended up removing Oh My Zsh entirely for a single .zshrc with everything they need. They also moved from Packer to Lazy.nvim and from iTerm to Ghostty the same way.
The shell became much faster, and Claude Code converted their configs in a matter of minutes.
My shell takes too long to start. Here's my .zshrc and the plugins I use: [paste]. Measure what's slow, then write a single self-contained .zshrc that keeps only these features: [list], without a framework. Show me the startup time before and after, and keep a backup of my old config.
