What it does
prismantis replaces Claude Code’s grey output with colour. Mermaid is drawn as real diagrams and charts instead of source, tables get coloured headers and alignment, and code gets a language header, Prism highlighting and a copy button. Tool call rows turn quiet, and `figure` blocks draw text pictures in theme colours. There are 16 themes plus `mono`, and colours can be overridden across 36 slots. LaTeX formulas are typeset as images in kitty and Ghostty through RaTeX and stay text in other terminals. The `/prismantis setup` command picks a theme from drawn samples, while `/prismantis demo` starts a feature tour. The plugin also runs in Codex and OpenCode.
Who it is for. Claude Code terminal users tired of monochrome output and raw mermaid in replies.
Good fit when
- A reply with a mermaid diagram should show a chart instead of source text.
- Tables with numbers should be read in colour and aligned to the terminal.
- A code block has to be copied with one button.
- LaTeX formulas should render typeset in kitty or Ghostty.
Not a fit when
- Claude Code is older than 2.1.287, where mods do not load.
- Stock output without changes is required for scripts and logs.
- The terminal does not support colour.
Example request
Draw the deploy flow in mermaid and a comparison table of three options in the prismantis-dracula theme.Limitations
Claude Code 2.1.287 or newer is required. The plugin makes no network calls and runs a program only when you press the `⧉ html` and `▣ png` buttons (the clipboard helper) or turn LaTeX on (the RaTeX renderer). Formulas are typeset as images in kitty and Ghostty only. Updating takes two commands and `/reload` in every open session. Codex and OpenCode have separate READMEs listing what works.
How to disable. Run `claude plugin uninstall prismantis@prismantis` or switch the plugin off through `/plugin`. Claude Code’s own renderer comes back at once.
FAQ
How do I install prismantis?
With two commands in Claude Code: `/plugin marketplace add NahumLitvin/prismantis` and `/plugin install prismantis@prismantis`. Then `/prismantis setup` picks a theme.
Does the plugin use the network?
No, there are no network calls. A program runs only for the html and png copy buttons or when LaTeX is on.
How do I turn it off?
Through `/plugin`: Claude Code’s own renderer returns at once. Full removal is `claude plugin uninstall prismantis@prismantis`.
How do I enable LaTeX math?
Install the RaTeX renderer and set `latex` to `true`. Until then formulas draw as text, and as images only in kitty and Ghostty.
Does it work outside Claude Code?
Yes, there are versions for Codex and for OpenCode 2.2.5 and later. Install and limits are in `codex/README.md` and `opencode/README.md`.
