What the check found

Every finding on this listing, and what each one means for whether it loads.
Finding	What it means
Missing files	It points at files that are not in the repository, so those steps will fail.
No license	The repository ships no license file, so the reuse terms are unclear.

Files it references that are not in the repository

report.md
trace.js
trace.js

What it says it does

Summarize a large Chrome DevTools performance trace into a compact markdown report so it can be reasoned about without loading the whole file. Use when given a Chrome/DevTools/Performance-panel trace (a multi-MB `Trace-*.json` or `*.json` with `traceEvents`) and asked to find what is slow, what runs too often, long tasks, jank, or hot JS functions.

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 2026-08-13.

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/tldraw/tldraw.svg)](https://skillworks.kynth.studio/?q=tldraw%2Ftldraw)

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.
