browser_visible

browser_visible is a skill for Claude Code, Codex from agentscope-ai/QwenPaw. It costs 75 tokens per session (464 once invoked), scanned A, original, Apache-2.0.

Browser launch controls for choosing whether the browser window is visible and how older private-mode settings are handled.

In plain words
What is it for?
Use it to start a visible browser window or keep the default hidden window while maintaining compatibility with older calls.
Why use it?
It makes browser startup predictable when debugging or working with older configurations. Private mode no longer changes the startup method.

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

browser_visible 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 12d 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

Deprecated: This reference supports the stable browser implementation. hatch. Prefer the unified browser tool when experimental mode is enabled.

Browser Launch Modes

browser.start launch modes:

  • Default: Playwright-managed, no debugging port
  • cdp_port=N: managed CDP, opens a local debugging port so other local tools can attach (see the browser_cdp skill)
  • private_mode=true: same as the default, kept for backward compatibility

Parameter meanings:

  • headed: whether to display the browser window
  • private_mode: kept for backward compatibility; it no longer changes the launch mode

The two parameters are independent and can be freely combined.

Common Usage

Default launch:

{"action": "start"}

Open a visible window:

{"action": "start", "headed": true}

private_mode

Already the default behavior — do not set it. The parameter is kept only so that older calls keep working, and passing it together with cdp_port is rejected.

Notes

  • The default is Playwright-managed with no debugging port
  • The launch mode is entirely determined by the call parameters
  • Managed CDP requires Chrome / Chromium / Edge to be installed locally
  • When the user manually operates the visible browser, the idle timer may not be refreshed
  • private_mode is an explicit parameter for each start call and is not persisted
  • If a browser is already running, you must stop it and then start again to switch launch modes or window visibility
  • Visible mode occupies the desktop and requires a graphical environment; it may not work on servers or headless environments
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.
