website-study

website-study is a skill for Claude Code, Codex from Akakaui/visual-browser-agent. It costs 38 tokens per session (994 once invoked), scanned A, original, MIT.

A method for studying how a public website looks and behaves across screen sizes. It examines design, interactions, accessibility, page structure, and motion using structured inspections and selected screenshots or recordings.

In plain words
What is it for?
Use it for design inspiration, user-experience research, responsive-layout study, accessibility checks, and analysis of hover states, clicks, transitions, and animations.
Why use it?
It gives you a repeatable way to understand a site instead of relying on a quick visual impression. Comparing desktop, tablet, and mobile views reveals changes that may otherwise be missed.

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

website-study 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 3d 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.

Website Study Skill

When to Use

Use this skill when the user wants to analyze a public website's:

  • Visual design (typography, colors, spacing, layout)
  • Interactions (hover states, clicks, transitions)
  • Responsiveness (breakpoints, mobile/desktop)
  • Motion/animations
  • Information architecture
  • Accessibility

Instructions

Phase 1: Planning

  1. Clarify scope: Which pages? Which viewports? What aspects matter most?
  2. Create run context with createRunContext(goal, requirements)
  3. Define viewports (default: desktop 1280x720, tablet 768x1024, mobile 375x667)

Phase 2: Structured Inspection

For each page and viewport:

  1. navigate(url, waitUntil: "networkidle")
  2. inspect_page(includeA11y: true, includeDOM: false) - get accessibility tree
  3. capture_screenshot(action: "viewport-{name}", requirement: "{name} layout")
  4. Extract: colors, fonts, spacing, component inventory

Phase 3: Interaction Study

For key interactive elements:

  1. Identify interactive elements from accessibility tree
  2. For each: hover, click, focus states
  3. record_interaction for transitions/animations
  4. capture_screenshot for each state

Phase 4: Responsive Audit

Use responsive_audit workflow tool or manual:

  1. Test each viewport breakpoint
  2. Check: navigation, content reflow, touch targets, readability
  3. Document issues with screenshots

Phase 5: Animation Study

Use animation_study workflow tool or manual:

  1. Identify animated elements
  2. Trigger animations (hover, click, scroll, load)
  3. record_interaction with 8-second clips
  4. Analyze: easing, duration, purpose, performance

Phase 6: Vision Review

For each captured artifact:

  1. review_visual_evidence(artifacts, requirement, context)
  2. Document findings, confidence, pass/fail
  3. Build evidence manifest

Phase 7: Synthesis

  1. Compile findings into structured report
  2. Include: design system analysis, interaction patterns, responsive issues, animation quality
  3. Reference all evidence with event IDs
  4. Save as artifact (Markdown/HTML)

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.
