A command-line browser that can open websites, inspect their interactive elements, take screenshots, and perform actions in Chrome. It can also be used from Python with matching functions.

Use it to navigate pages, discover buttons and fields, click visible controls, manage tabs, take screenshots, and turn browser workflows into Python scripts.

It helps an agent understand a page before acting on it, rather than relying only on its source code or a visual guess. It can run in a headless session or a visible Chrome window.

browser — Skill for Claude Code and Codex by sudoprivacy/sudocode

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 sudoprivacy/sudocode --skill browser

Clone the repo

git clone --depth 1 https://github.com/sudoprivacy/sudocode

Made for: Claude Code, Codex.

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	$0.00020	$0.00374
Opus 5.5	$0.00008	$0.00150
Sonnet 5.5	$0.00004	$0.00075
Haiku 4.5	$0.00002	$0.00037

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 21d 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

Browser

Use the installed ai-dev-browser package. Its CLI modules are generated from ai_dev_browser.core; use the same functions for Python automation. Install the package in your Python environment before invoking the tools.

Discover commands

python3 -m ai_dev_browser.tools.browser_start --help
python3 -m ai_dev_browser.tools.page_discover --help

Quick-start examples

python3 -m ai_dev_browser.tools.browser_start
python3 -m ai_dev_browser.tools.page_goto --session-id <returned-id> --url https://example.com
python3 -m ai_dev_browser.tools.page_discover --session-id <returned-id>
python3 -m ai_dev_browser.tools.click_by_text --session-id <returned-id> --text "Sign in"
python3 -m ai_dev_browser.tools.page_screenshot --session-id <returned-id> --path screenshot.png
python3 -m ai_dev_browser.tools.browser_stop --session-id <returned-id>

Choose headless/headful from the task and user preference; use browser_connect to attach to an existing browser. Connecting preserves its current mode. Use the session identity returned by start/connect for subsequent commands. browser_stop closes an owned browser; use browser_disconnect to release control of an attached browser while preserving its windows and tabs. Consult --help for the selected tool before configuring transport or profile settings. To inspect screenshot pixels, use scode's Read tool on the saved image.

The same operations are available from Python:

from ai_dev_browser.core import page_goto, click_by_text, page_discover

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.
