Use the open-source free `ReportGenerator` tool for turning .NET coverage outputs into HTML, Markdown, Cobertura, badges, and merged reports. USE FOR: the repo uses or wants ReportGenerator; CI needs human-readable coverage reports; multiple coverage files must be merged. DO NOT USE FOR: raw coverage collection with no reporting need. INVOKES: inspect the repository context, edit targeted files, and run relevant build, test, lint, or validation commands when changes are made.
