GitHub – nicobailon/visual-explainer: Agent skill that generates rich HTML pages or slide decks for diagrams, diff reviews, plan audits, data tables, and project recaps

Visual Explainer Turns Messy Terminal Output into Beautiful, Readable Pages

If you’ve ever asked a coding agent to draw a system diagram in your terminal, you know the feeling. You expect clarity. Instead, you get a maze of box drawing characters, arrows made of dashes, and tables that wrap awkwardly across your screen.

It works… technically. But it’s hard to actually think with.

That’s exactly the problem Visual Explainer is solving. You can check it out here:

At its core, this GitHub project is an agent skill that transforms complex terminal output into rich, styled HTML pages. Instead of dumping ASCII diagrams or pipe-filled tables into your console, it generates a clean, self-contained HTML file and opens it in your browser. Real typography. Proper spacing. Dark and light themes. Even interactive Mermaid diagrams with zoom and pan.

And honestly, that changes the experience more than you’d think.

Imagine reviewing a large diff. Or comparing 15 requirements against a project plan. In the terminal, that usually becomes a wall of text you scroll through half-blind. With Visual Explainer, it becomes a structured page you can actually scan. Tables render like real tables. Architecture diagrams use CSS Grid. Dashboards can use Chart.js. It feels less like debugging in 1998 and more like working with modern tools.

It even detects when output is getting unwieldy, for example large tables, and automatically switches to HTML rendering. And if you prefer presenting instead of just reviewing, you can generate slide decks with a simple flag.

No heavy setup. No complex dependencies. Just a browser.

We’ve come a long way from squinting at monospaced diagrams. Tools like this hint at a future where AI doesn’t just generate answers, it presents them in ways that actually support how we think and collaborate. And that’s a shift worth paying attention to.
