nodetool: Skill for Claude Code

.claude/skills/yts806379-everything-claude-code-e2e-testing/SKILL.md

e2e-testing is a skill for Claude Code, Codex from nodetool-ai/nodetool. It costs 79 tokens per session (2,277 once invoked), scanned A, original, AGPL-3.0.

A guide to end-to-end browser testing with Playwright, a tool that drives a real browser to check complete user workflows. It also covers Electron application tests, reusable page objects, continuous integration, test artifacts, and flaky tests.

In plain words
What is it for?
Use it to create, repair, debug, stabilize, and run Playwright tests for web and Electron applications, including visual and CI test suites.
Why use it?
It helps developers write tests that reflect how users interact with the application and diagnose tests that fail inconsistently.

Skill for Claude CodeCodex

Written for Claude Code and Codex: installed under .claude/, but also agents/openai.yaml present.

This is nodetool-ai/nodetool's own configuration. It tells Claude Code and Codex how to work on nodetool itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything nodetool configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 9d 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 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.
