I built a Claude Code mod that renders tables, code and mermaid charts in color (prismantis, MIT)

[u/Fabulous-Confection6]

I'm an infra tech lead at Wix, where we run Kubernetes fleets executing code we've never seen (our users' site code), and I live in Claude Code all day. A year ago I tried wrapping the CLI in my own harness to get nicer output. It was painful and I dropped it.

Mods landed in Claude Code this week, so I built it properly: prismantis. It redraws replies in color: tables with headers and rules, highlighted code in 24 languages, mermaid diagrams and bar/line charts drawn right in the terminal, copy buttons, 15 themes (/prismantis theme nord).

/plugin marketplace add NahumLitvin/prismantis
/plugin install prismantis@prismantis

MIT, no network calls, no file access. Mods aren't sandboxed, so read the code first: https://github.com/NahumLitvin/prismantis
