I made Claude Code draw mermaid diagrams, formulas and video inline in the terminal

A reply in Claude Code is plain text, so a mermaid block stays code and a formula stays raw LaTeX. I wanted them drawn, so I wrote a few mods: reply-media draws mermaid fences, math formulas and local images as real pictures in the terminal. A local video shows its first frame with a play button and plays in place. reply-markdown draws headings, lists, callouts and tables in color, and puts each code fence in a card with a copy button. a status line with context used, cost, tokens per second, cache hit rate, git state, usage windows, and what my other sessions are doing. Demo GIF and screenshots are in the README: https://github.com/NateCC0902/NeonCoat Before you try it: It uses Claude Code's mod API (function-hook plugins). That API is early access, so it can break. macOS only, and the pictures need a terminal with kitty graphics (Ghostty or kitty). Claude writes the forms the mods draw only if you add a few lines to your CLAUDE.md. The README has them. MIT licensed, and built with Claude Code itself. Tell me what breaks. submitted by /u/No-Creme2531 [link] [comments]
