A headless browser tool that controls a web browser without displaying it on screen. It can open pages, inspect their accessible elements, click, type, scroll, take screenshots, run JavaScript, and read console errors.

Navigating websites, filling forms, checking page behavior, capturing full-page screenshots, running page scripts, and investigating browser console problems.

It lets an agent test or inspect websites through real browser interactions instead of relying only on source code or HTTP requests. Separate sessions can keep browser tasks isolated.

browser — Skill for Claude Code and Codex by fisker086/AIOps

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 fisker086/AIOps --skill browser

Clone the repo

git clone --depth 1 https://github.com/fisker086/AIOps

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	$0.00030	$0.00515
Opus 5.5	$0.00012	$0.00206
Sonnet 5.5	$0.00006	$0.00103
Haiku 4.5	$0.00003	$0.00052

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.

What it actually says

Browser Skill

Provides server-side headless browser automation using agent-browser CLI (Playwright/Chromium backend):

Navigate to URLs (with auto-snapshot and bot detection)
Snapshot accessibility tree with element references (e.g., @e5)
Click elements by reference
Type text into input fields
Scroll up/down
Navigate back in history
Press keyboard keys
Take full-page screenshots (base64 PNG)
Execute JavaScript in page context
Read console messages and JS errors
Session isolation per task_id

Use builtin_browser tool with fields:

operation: one of "navigate", "snapshot", "click", "type", "scroll", "back", "press", "screenshot", "eval", "console", "close"
url: URL to navigate to (required for navigate)
ref: Element reference from snapshot (e.g., @e5) for click/type
text: Text to type (for type) or key to press (for press)
js: JavaScript expression to evaluate (required for eval)
task_id: Session identifier (default: "default"); each task_id gets its own browser session
direction: Scroll direction "up" or "down" (default: "down")
full: Full page screenshot "true"/"false" (default: "false")
clear: Clear console/errors after reading "true"/"false"

Response format:

Always return the result in a single message. When taking a screenshot, embed the base64 PNG inline in your reply via ![alt](data:image/png;base64,...) — do not split into multiple messages.

Notes:

Requires agent-browser CLI installed: npx agent-browser install --with-deps
Each task_id maintains an isolated browser session with persistent state
Sessions auto-clean after 5 minutes of inactivity
Element references from snapshot (e.g., @e5) are used for click/type — not CSS selectors
For simple HTTP fetches, prefer builtin_http_client (faster, lighter)

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.
