What is springsentinel-action?

springsentinel-action is a GitHub Action, meaning a piece of automation that plugs into GitHub's continuous integration system, that runs a static analysis tool called SpringSentinel on Java projects built with the Spring Boot framework. Static analysis means checking the source code for problems without actually running the program. It checks things like the design of REST APIs, how the code uses JPA and Hibernate for database access, whether it follows common security best practices, and whether the overall architecture of the project follows expected patterns. You add it to a project by including a short block in a GitHub Actions workflow file, listing this action as one of the steps that runs whenever code is pushed or a pull request is opened. Once wired in, it checks out the code and runs the analysis automatically as part of that workflow, without any extra setup steps needed inside the job itself. Each time it runs, it produces several outputs at once: an HTML report that gets uploaded as a downloadable file attached to the workflow run, a JSON report, and a SARIF report, which is a standard format that GitHub can read directly to show security and code quality alerts inside its own Code Scanning feature. When it runs on a pull request, it also automatically posts a short summary comment on that pull request listing how many issues were found and what categories they fall into, such as REST API design problems. Using it requires the target project to be a Java project built with Maven. Getting GitHub's Code Scanning alerts specifically requires either a public repository or GitHub Advanced Security enabled on a private one, though the HTML report and pull request comment are available either way. The project is related to a separate Maven plugin also called SpringSentinel. The README does not state a license.
