Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Deletes files or strips permissions src/build-error-decoder.js:180, [пакет] src/build-error-decoder.js:180

    fix: `rm -rf .next

Dev error explainers — questions

Answers built from our own checks of this server.

Why is there no uptime for Dev error explainers?

Dev error explainers runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package dev-error-explainers was installed 27 times last week.

How do I connect Dev error explainers?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls dev-error-explainers straight from npm; nothing to host, nothing to sign up for.

How many people use Dev error explainers?

The npm package dev-error-explainers was installed 27 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Dev error explainers open source?

Yes — it is published under the MIT licence, written in JavaScript, 0 stars on GitHub and 2 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
