VSTS External WorkItem is a Chrome extension developed by Clément Mesureux. It falls under the category of Browsers and belongs to the subcategory of Add-ons & Tools. This extension allows users to handle external work items within the Visual Studio Team Services (VSTS) platform.

Upon installation, users can input their Visual Studio Team Services URL and their work item system base URL. The extension then injects a JavaScript file into VSTS and removes the official work item module. This enables users to utilize an external work item system.

One of the main features of VSTS External WorkItem is its ability to complete pull requests based on the matching of patterns with the description field. If a pattern is found, users can easily complete their pull request. If no pattern matches, the button for completing the pull request is removed.

With VSTS External WorkItem, Chrome users can seamlessly integrate external work item systems into their VSTS workflow, enhancing their productivity and efficiency.
