e2e-test

e2e-test is a skill for Claude Code from johnqtcg/awesome-skills. It costs 70 tokens per session (5,173 once invoked), scanned A, original, MIT.

A guide for designing and maintaining end-to-end tests, which check complete user journeys through an application. It uses Agent Browser for exploration and Playwright for test suites and continuous integration.

In plain words
What is it for?
It helps plan journey coverage, write or update Playwright tests, explore behavior, investigate flaky failures, collect test artifacts, configure CI checks, and test content inside iframes.
Why use it?
It helps make these broad tests reliable, repeatable, and useful when diagnosing failures. It also defines ways to handle flaky tests and collect evidence for regressions.

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-test 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 16d ago.

The scan reads SKILL.md. This mod also ships 10 executable files (scripts/discover_e2e_needs.sh, scripts/lint_e2e_spec.py, scripts/run_regression.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

E2E test

Use this skill to create E2E coverage that is deterministic, evidence-backed, and maintainable in real repositories.

Quick Reference

Do not use this skill for visual design review with no automated journey value, performance/load testing, or tests that would require guessed secrets, endpoints, or private accounts.

Load References Selectively

The scripts ship with this skill, not with the repository under test: invoke them via ${CLAUDE_SKILL_DIR} as written. From the target repository a bare scripts/… path names that repository's own directory — missing, or a different program.

Load on demand, not up front. A typical Playwright coding task needs the two every-task rows plus playwright-patterns.md — three files. Everything below that is conditional; open it when the trigger in the first column actually applies.

e2e-test is a skill published in the GitHub repository johnqtcg/awesome-skills (30 stars, last pushed 16d ago), licensed MIT. It adds 70 tokens to every session and 5,173 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-30.
