visual-explainer-extension GEMINI.md

visual-explainer-extension GEMINI.md is an instructions file for Gemini CLI from Jakedismo/visual-explainer-extension. It costs 806 tokens per session, scanned A, original, MIT.

Project instructions for Visual Explainer, an agent skill that turns terminal output into self-contained, styled HTML pages with diagrams, tables, and charts.

In plain words
What is it for?
Use them when changing the Gemini CLI extension, its HTML visualizations, Mermaid diagrams, charts, commands, or image-generation tools.
Why use it?
They explain the extension's structure, technologies, and commands so agents can work on it consistently.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

visual-explainer-extension GEMINI.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

visual-explainer

An agent skill that turns complex terminal output into styled HTML pages you actually want to read.

ABOUTME: This project is an agent skill for Gemini CLI that generates beautiful, self-contained HTML pages for diagrams, diff reviews, plan reviews, and data tables. It also includes native AI image generation tools.

Project Overview

visual-explainer replaces ASCII art and box-drawing tables with interactive HTML pages featuring real typography, dark/light themes, and Mermaid diagrams. It also provides built-in tools for generating images, icons, and patterns via the Gemini API.

Main Technologies

  • HTML/CSS: Vanilla implementation for self-contained portability.
  • Mermaid.js: For flowcharts, sequence diagrams, and topology.
  • Chart.js: For dashboards and metrics.
  • Node.js / MCP: Native image generation tools using the Gemini API.

Extension Structure

  • gemini-extension.json: Manifest defining extension metadata and MCP server.
  • package.json: Project metadata and Node.js dependencies.
  • commands/: Custom slash commands (TOML format) available in Gemini CLI.
  • skills/: Agent-activatable workflows (e.g., visual-explainer/SKILL.md).
  • references/: Reference material the model reads before generating output.
  • templates/: Reference HTML structures for different visualization types.

Available Commands

Visualization Commands

Command Description
/diff-review Visual diff review with architecture comparison.
/fact-check Verify accuracy of a document against code.
/generate-slides Generate a magazine-quality slide deck.
/generate-visual-plan Generate a visual implementation plan.
/generate-web-diagram Generate an HTML diagram for any topic.
/plan-review Compare a plan against the codebase.
/project-recap Mental model snapshot for context-switching.
/visual-code-explain Explain the logic of a generated code file, mapping user intent to implementation.
/code-archetype Generate a technical icon and structural card for a module or subsystem.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
