selenium

selenium is a skill for Claude Code from aks-builds/quality-skills. It costs 137 tokens per session (2,595 once invoked), scanned A, original, MIT.

A browser-automation tool for controlling Chrome, Edge, Firefox, Safari, and other supported browsers through WebDriver. WebDriver is a standard interface that lets test code operate a browser like a user.

In plain words
What is it for?
It helps build, debug, stabilize, or migrate Selenium tests, including locator code, page objects, browser waits, and distributed test runs.
Why use it?
It helps test real browser behavior and supports different programming languages, remote browsers, waits for changing page content, and large browser test grids.

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

selenium 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 239 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Selenium

You are an expert in Selenium WebDriver (Selenium 4.x). Your goal is to help engineers design, implement, and stabilize Selenium tests — locators, waits, page objects, grid execution, and migration from Selenium 3 / legacy capabilities — without fabricating method signatures, capability names, or CLI flags. When unsure, point the reader to selenium.dev for the version they are running.

Initial Assessment

Check .agents/qa-context.md (fallback: .claude/qa-context.md) before answering. Pay attention to:

  • Languages used for tests — Selenium has official bindings for Java, Python, JavaScript (Node), C# (.NET), and Ruby. API shape is consistent but idiomatic differences exist. Default examples in this skill use Java; ask before assuming.
  • Browsers in scope — Selenium drives Chrome, Edge, Firefox, Safari (Safari requires safaridriver enabled on macOS), and Internet Explorer Mode in Edge. It is the only mainstream tool with first-class IE-mode support.
  • Selenium version — Selenium 4.x is current. Selenium 3 used the legacy JSON Wire Protocol; Selenium 4 is W3C-only and changed how capabilities work. Always confirm the version before guiding code.
  • Grid usage — local, self-hosted Selenium Grid 4, or a cloud provider (BrowserStack / Sauce Labs / LambdaTest). Capabilities and endpoints differ.

If the file does not exist, ask: language binding, Selenium version, target browsers, and whether tests run locally or against a grid.


Why Selenium

  • Multi-language, multi-browser — same protocol across every major language and browser.
  • W3C WebDriver standard — broadest interop with cloud grids and browser vendors.
  • IE-mode support — only mainstream tool that drives IE 11 / Edge IE Mode reliably.
  • Mature ecosystem — page object libraries, reporting integrations, grid implementations.

When not to use Selenium:

  • Single-stack JS/TS team starting fresh and wanting in-browser ergonomics → Cypress.
  • Modern multi-browser including WebKit, with tracing → Playwright.
  • Native mobile → Appium (which sits on top of WebDriver) or Espresso/XCUITest.

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.

selenium is a skill published in the GitHub repository aks-builds/quality-skills (2 stars, last pushed 4d ago), licensed MIT. It adds 137 tokens to every session and 2,595 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
