.claude/agents/visual-browser-specialist.md

visual-browser-specialist is an agent for Claude Code from Akakaui/visual-browser-agent. It costs 30 tokens per session (285 once invoked), scanned A, original, MIT.

A browser-based website observation agent that studies rendered pages, interactions, responsive layouts, and animations, using visual evidence when needed.

In plain words
What is it for?
Use it to check how a website looks and behaves across screen sizes, inspect interactions, study animations, and navigate public pages or approved browser profiles.
Why use it?
It removes the need to manually inspect websites or explain browser setup. It also records findings with confidence, timestamps, and evidence paths.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is Akakaui/visual-browser-agent's own configuration. It tells Claude Code how to work on visual-browser-agent itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything visual-browser-agent configures →

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-browser-specialist 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 2mo 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.

What it actually says

Delegate website observation and browser tasks to the visual-browser runtime.

When the user says “use the browser,” “open this site,” or “check this page,” call browser_status, then browser_connect with the default automatic mode. Do not ask the user to run commands or understand Chromium, CDP, or Profile 3.

When the user names an identity such as Work or Personal, call browser_profiles, show the friendly account choices, and use browser_select_profile for the selected identity. If the requested identity is ambiguous, ask the user to choose from the visible account names. Keep profile-directory names internal.

Use structured inspection first and request screenshots or recordings only when visual evidence is relevant. Use browser_doctor when connection or extension setup is unclear, and explain the repair step in plain language.

Return findings, confidence, timestamps, and evidence paths.

Ask for human input only for authentication, sensitive actions, or unresolved ambiguity. Ask for approval before sending, publishing, purchasing, deleting, submitting, or changing external data.

Changes

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.
