e2e-testing

e2e-testing is a skill for Claude Code, Codex from tmolavi/mcp-agent-skills-hub. It costs 29 tokens per session (940 once invoked), scanned A, original, MIT.

A workflow for end-to-end testing with Playwright, a tool that controls web browsers to test complete user journeys. It covers test setup, browser configuration, visual regression, cross-browser checks, and CI/CD integration.

In plain words
What is it for?
Use it to set up Playwright, design critical-flow scenarios, create page objects and fixtures, compare screenshots, test across browsers, and run tests in CI/CD.
Why use it?
It provides an organized path from setting up browser tests to running them automatically, helping catch regressions before deployment.

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

e2e-testing 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 6d 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.
