What the check found

Every finding on this listing, and what each one means for whether it loads.
FindingWhat it means
Unknown toolsIt allow-lists tool names Claude Code does not ship, which usually means a typo.

What it says it does

Certification coach for Flows apps. Captures the app name, value case, persona, problem, and design intent through a structured conversation and writes App-Brief.md at the repo root. This is the FIRST step of the Flows app certification flow — run it immediately after `npx @cognite/cli apps create`, before building. Use when the user asks to start an app brief, run the certification coach, fill out the app brief, or run flows-app-brief.

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 2026-08-14.

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 badge

[![SkillWorks](https://toolproof.kynth.studio/badge/skillworks/cognitedata/builder-skills.svg)](https://skillworks.kynth.studio/?q=cognitedata%2Fbuilder-skills)

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.
