# prismantis

A Claude Code mod that redraws replies in color with tables, headings, lists, quoted text, highlighted code, numbers, paths, links, mermaid diagrams, charts and tool rows, offering 17 themes and copy buttons.

## Description

Prismantis is a Claude Code plugin that renders Claude's replies in color. It styles tables, headings, lists, quotes, highlighted code, numbers, paths, links, mermaid diagrams, charts, and tool rows across 17 themes, with copy buttons. The `/prismantis setup` command selects a look, and `/prismantis demo` previews everything. The plugin makes no network calls; it uses local clipboard helpers (`osascript`, `powershell.exe`, or `copyq`), reads local PNG images and ratex-render output, and saves only its own options via `/config`. It hooks `ui.render`, `command.run`, `prompt.submit`, and `engine.create`, and exposes `prismantis.markdown` to other mods. Licensed MIT by Nahum Litvin.

## Install

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

## Original README

# prismantis

A Claude Code mod that redraws Claude's replies in color: tables, headings, lists, quotes, highlighted code, numbers, paths and links, mermaid diagrams and charts, and tool rows, in 17 themes, with copy buttons. Run `/prismantis setup` to pick a look, or `/prismantis demo` to see everything it draws.

Screenshots, every option and the changelog are in the [full README](https://github.com/NahumLitvin/prismantis#readme).

## What it runs, reads and changes

Prismantis makes no network calls. Everything below stays on your machine.

- **Programs.** Clicking `⧉ html` or `▣ png` runs the clipboard helper with the copied table, diagram or figure on stdin: `osascript` on macOS, `powershell.exe` on Windows (it reads `SystemRoot` to find it), or `copyq` on Linux. With `latex` on, it runs `ratex-render` from your `PATH` with the reply's formulas on stdin. It runs nothing else.
- **Files.** It reads a local PNG that a reply links as a Markdown image, up to 2 MB, to draw it in kitty or Ghostty. It reads back the PNGs `ratex-render` writes to `$TMPDIR/prismantis-latex-<session>-<id>`. It writes no files itself.
- **Settings.** `/prismantis setup` and `/prismantis theme` save your pick through `/config`, only into prismantis's own options (`prismantis.theme`, `prismantis.tableStyle` and the other setup steps). Nothing else in your settings changes.
- **Hooks.** It draws through `ui.render`, answers the `/prismantis` command through `command.run`, adds the model-only [diagram hints](https://github.com/NahumLitvin/prismantis#diagram-hints) note in `prompt.submit`, and adds `$.prismantis.markdown` for [other mods](https://github.com/NahumLitvin/prismantis#other-mods) in `engine.create`. `prismantis.markdown` is that call's own event.
