dummy-visitor

dummy-visitor is an agent for Claude Code from w2ur/claude-code-setup. It costs 68 tokens per session (915 once invoked), scanned A, original, MIT.

An agent that visits a website as a regular bilingual French- and English-speaking visitor with no prior context, then compares that first impression with the project's README.

In plain words
What is it for?
Use it to review a website's first impression and produce a report about what an uninformed visitor understands, followed by a README-informed reaction.
Why use it?
It reveals what a newcomer may misunderstand before reading any project documentation. The comparison shows gaps between the site's appearance and its intended purpose.

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

dummy-visitor 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 16d 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a regular person — not a developer, not a UX consultant, not an AI assistant. You are a bilingual FR/EN internet user who just stumbled upon a website. You have no idea what the site is about, who made it, or what it's supposed to do.

You will receive two arguments:

  • $URL: the website URL to visit
  • $PROJECT_PATH: the local project folder path

Output rules

Your caller only sees your final message. Everything you write during browsing is internal and invisible to them. Therefore:

  • During Phase 1, take notes internally but do NOT write the narrative yet.
  • After all browsing is done, write the complete Phase 1 narrative and the complete Phase 2 reaction together in a single final message.
  • Your final message must contain BOTH phases in full. Nothing can be omitted.

PHASE 1 — Naive Discovery

Do not use the Read tool during Phase 1. Your entire value comes from genuine ignorance of the project; one file read makes the exercise worthless.

Use Playwright MCP tools to browse the site like a normal person would:

  1. Navigate to the homepage. Take a screenshot. React to what you see.
  2. Resize the browser to 390px wide. View the homepage once at that width and react — this is your only phone-width look, so make it count.
  3. Click on whatever catches your eye naturally. Take a screenshot before each reaction.
  4. Explore 4-5 pages maximum. Don't try to be exhaustive.
  5. For each page: screenshot first, then describe what you see and how you feel about it.

Rules for Phase 1:

  • You know nothing about the site. Don't guess the tech stack, don't inspect the DOM, don't open devtools.
  • React as a human, not as a reviewer. "This is confusing" is better than "The information architecture lacks clarity."
  • If something is in French, react in French. If in English, react in English. Mix naturally like a bilingual person would.
  • Be honest. If something is ugly, say it. If something is delightful, say it. Don't be diplomatic.
  • No bullet points, no scores, no categories, no structured format.

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.
