Technical debt is one of the major concepts SonarQube deals with. The technical debt of a file is the sum of the technical debt contributed by each issue detected on this file.

The expanded Technical Debt and Issues tab offers three different kinds of actions to understand and manage a file's technical debt:

To better understand how to review issues (comment, assign, link to an action plan, ... etc), please read Reviewing Issues.

For performance and usability reasons, only the first 100 relevant issues in a file will be displayed. If the selected filter is supposed to show more than 100 issues, only the first 100 will have the detail block available for review, the remaining ones will only be shown with the squiggle line. When this happens, a warning bar is displayed across the top of the file. 

Bulk actions will be applied to all issues matching the current filter, not just the first 100.
