Tool-CritiqueBrowser was created on the basic of CriticBrowser. CriticBrowser uses a deprecated version of Spec. Tool-CritiqueBrowser uses the new version of Spec2; It is a graphical tool that allows developers to select a list of software packages and a list of quality rules, this resulting on a new list of critiques that broke the selected rules. Tool-CritiqueBrowser helps Pharo developers avoid inspecting method by method to see if there are critiques to fix them.
In order to install this tool, perform the following code in a Playground:
Metacello new
baseline:'ToolCritiqueBrowser';
repository: 'github://AleCossioCh/Tool-CritiqueBrowser:master/src';
load.
Once you have installed, select Browse and then click on CritiqueBrowser with error icon 
Next step is selecting packages and rules, as example:
- You can use the filter to look for your packages faster
The migration of this tool as well as the improvements to the UI are part of my project to GSoC21; For more information, see the Refining code critics proposal. About the work and some tutorials, you can visit the GSoC'21 summary blog.
"It is worth mentioning that the developers of CriticBrowser confused the word critique (an instance of criticism) with critic (a person who criticizes)" (Yuriy Tymchuk's, Quality-Aware Tooling, 2017 : p.52) I saw an opportunity to rename the tool :)
