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

MUST be used whenever fixing test coverage for a Flows app to meet the 80% line coverage hard gate. This skill finds AND fixes coverage gaps — it configures tooling, writes missing tests, covers untested paths, and refactors code for testability. It does not just report. Triggers: test coverage, fix tests, write tests, add tests, coverage fix, 80% coverage, coverage gate, missing tests, testability, vitest coverage, jest coverage.

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.
