About this mod

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.

Original text / 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.

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 note in prompt.submit, and adds $.prismantis.markdown for other mods in engine.create. prismantis.markdown is that call's own event.
