Please install the Claude Code mod "Prismantis" (https://github.com/NahumLitvin/prismantis). Before installing, read the Security and Requirements sections of its README and tell me what it reads and writes, which commands it runs, whether it uses the network, and which Claude Code version, OS and terminal it needs. If everything looks fine, run claude plugin marketplace add NahumLitvin/prismantis and claude plugin install prismantis@prismantis, then remind me to run /reload-plugins in my session.Send this to Claude Code so it reads the author’s instructions before installing.
git clone https://github.com/NahumLitvin/prismantis

Prismantis is a Claude Code mod that redraws Claude's replies in one of 15 themes, including Catppuccin, Dracula, Nord and Tokyo Night, switched on the spot with /prismantis theme <name>.
- Tables get colored headers, alignment and terminal-width sizing; code gets a language header, a copy button and Prism highlighting in 24 languages
- Diagrams:
mermaidflowcharts, sequence, state, class and ER diagrams, plusxychart-betabar and line charts, drawn as colored text art - Tool rows: each tool call becomes one line with a verb, a target and a status dot; the turn footer duration is colored
- Copy buttons on code, tables, lists and quotes; your prompts drawn as bubbles so you can find them when scrolling back; right-to-left layout for Hebrew and Arabic
The author states it makes no network calls, reads no files and runs no commands; it only redraws text already on screen. With diagramHints on (the default) it attaches a short model-only note to each prompt, about 190 tokens, which can be turned off in /config. Requires Claude Code 2.1.287+. Hand-tested in the macOS terminal only; Linux and Windows run CI tests, and desktop, VS Code and mobile are not hand-checked. Not run-tested by this site; the preview is illustrative.
