What is agent-browser?

A command-line browser automation guide for navigating websites, interacting with pages, extracting information, taking screenshots, and debugging browser actions.

Use it to open pages, fill forms, click controls, scrape content, manage tabs and frames, control network or storage state, and save screenshots or traces.

It makes browser tasks repeatable and helps avoid unreliable page interactions by using snapshots, selectors, waiting, and validation.

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	$0.00056	$0.01088
Opus 5	$0.00028	$0.00544
Sonnet 5	$0.00011	$0.00218
Haiku 4.5	$0.00006	$0.00109

Security

Grade A, and why

agent-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 4d 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.

Agent Browser

Overview

Use agent-browser to automate web UI tasks from CodeConductor. Prefer /browser <args> to execute commands through the built-in integration.

Quick start

Navigate: /browser open https://example.com
Snapshot: /browser snapshot
Act using refs or selectors (click, fill, type).
Validate with get or is commands.
Capture screenshot or trace if needed.
close when done.

Workflow

Define the target URL, required outputs, and authentication needs.
Set viewport/device/headers/credentials when required.
Use snapshot or find commands to locate elements deterministically.
Use wait to stabilize before actions.
Execute actions in small steps and validate with get or is.
Save artifacts (screenshot, state, trace) only when needed.
Close the browser.

Selector and waiting guidance

Prefer refs from snapshot output for deterministic targeting.
Use semantic locators: find role, find label, find text, find placeholder, find testid.
Use wait for elements, text, URL patterns, or network idle before actions.

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.
