Cake Issues provides aliases to create reports from the parsed issues. There's a generic reporting addin which allows to create reports using out-of-the-box or custom Razor templates.
Issues found on a feature branch can be reported as comments to pull requests giving developers instant and direct feedback. Currently Visual Studio Team Services and Team Foundation Server are supported.
The addins are built in a modular architecture and are providing different extension points which allow you to easily enhance it for supporting additional analyzers, linters, report formats and pull request systems.
