visual-explainer

visual-explainer is a skill for Claude Code, Codex from jircik/Visual-Explainer. It costs 71 tokens per session (1,827 once invoked), scanned A, original, MIT.

A tool that creates an interactive HTML dashboard explaining a codebase’s files, architecture, data flows, and important functions.

In plain words
What is it for?
It helps with codebase onboarding, architecture diagrams, project documentation, file-structure overviews, and tracing how data moves through a project.
Why use it?
It gives developers a visual overview of an unfamiliar project, reducing the time needed to work out how its parts fit together.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is → Run full analysis → generate ./visual-explainer/index.html.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Visual Explainer

Generate an interactive HTML dashboard that visually explains a codebase — its architecture, file structure, data flows, and the purpose behind every meaningful file and function.

When to Use

  • User asks to explain, visualize, or document a codebase
  • User wants to understand how a project works
  • User needs onboarding documentation for a repo
  • User asks for architecture diagrams or code maps

When NOT to Use

  • Single-file explanations (just explain inline)
  • Non-code projects (pure docs, assets)
  • The user only wants a README

Output

A self-contained ./visual-explainer/index.html file in the project root. No external dependencies except CDN links (Mermaid.js, Tailwind CSS, Inter font).

Process

Phase 1: Analyze

  1. Detect the project root. Use the current working directory.
  2. Read the file tree. Run find . -type f excluding: node_modules, .git, dist, build, .next, __pycache__, .venv, target, vendor, .cache, coverage dirs, and lockfiles.
  3. Detect the stack. Identify languages, frameworks, and tools from config files (package.json, pom.xml, Cargo.toml, pyproject.toml, go.mod, docker-compose.yml, etc.).
  4. Classify files. Sort every file into one of these categories:
    • Core — main application logic, entry points, route handlers, services, controllers, models, schemas
    • Config — environment, build, lint, CI/CD configs
    • Infrastructure — Docker, deployment, IaC
    • Test — test files, fixtures, mocks
    • Skip — lockfiles, generated code, binary assets, .gitignore, LICENSE, package-lock.json, etc.
  5. Read all Core files. Understand:
    • What each file does (purpose, not line-by-line)
    • Key exports, classes, functions, and why they exist
    • How files depend on each other (imports/requires)
    • The data flow: entry point → processing → output/response
  6. Read Config and Infrastructure files. Summarize what they configure and why.
  7. Skim Test files. Note what they cover, don't explain each test.

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.
