Browser automation tools for controlling Chrome tabs, including taking screenshots, filling forms, checking network requests and console errors, and sending text-to-speech notifications.

Useful for testing web pages, checking responsive layouts on emulated devices, submitting forms, investigating failed web requests, and reviewing JavaScript errors.

It removes the need to perform browser checks manually or switch between separate debugging tools.

browser — Skill for Claude Code by GGPrompts/TabzChrome

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add GGPrompts/TabzChrome --skill browser

Clone the repo

git clone --depth 1 https://github.com/GGPrompts/TabzChrome

Made for: Claude Code.

Or install tabz, the plugin that ships this one along with the rest of its 3 skills.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00036	$0.00887
Opus 5.5	$0.00014	$0.00355
Sonnet 5.5	$0.00007	$0.00177
Haiku 4.5	$0.00004	$0.00089

Security

Grade A, and why

browser 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.

Origin

This is a copy

88% identical to tabz-browser — 16 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What ships with it

10 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
