What it says it does

JavaScript and TypeScript patterns, anti-patterns, and quality rules — with deterministic regex-based anti-pattern detection for var usage, loose equality (==), leftover console.log, async without await, and common JS pitfalls. Covers Node.js, npm, ESLint, promise patterns, and async code. Use proactively when reviewing JS or TS source files for anti-patterns, running a pre-review scan before ESLint, catching known JS pitfalls, or auditing Node.js or browser codebases. Run the checker for deterministic scanning.

Every number above came out of reading the file and its repository. Nothing is a judgement call, nothing is a model’s opinion, and nothing can be paid for. The full method is published. Source last committed 2026-08-17.

Put this measurement in your README

A badge carrying how many listings this index holds from the repository and how many pass every static structural check. It reads from this index every time somebody loads your page, so it changes when the measurement changes and there is nothing to keep up to date. Free, no account, and the value is not something you or we can set by hand.

[![SkillWorks](https://toolproof.kynth.studio/badge/skillworks/Everyone-Needs-A-Copilot/claude-copilot.svg)](https://skillworks.kynth.studio/?q=Everyone-Needs-A-Copilot%2Fclaude-copilot)

Would rather not hotlink us? Every badge is also served in shields.io’s endpoint schema, so shields renders the image and your readers never talk to our domain:

Published by Toolproof, the masthead over this index and eight others. The method behind the number is at toolproof.kynth.studio/methodology, and the whole thing is readable as JSON with no key at /api.
