-### Coverage Tools
-- `coverage_analyze` - Run all tests with coverage collection
-- `coverage_report` - Module/class/method tree with line and block counts
-- `coverage_show` - Open the Code Coverage Results window
+Terminal output is not captured. The Visual Studio terminal is a raw PTY with no exit code or command boundaries, so `terminal_run` reports only whether the terminal opened. To read results, redirect output to a file and read it back with `document_read`.
 
-Running coverage is edition-gated (Enterprise through VS 2022, all editions from VS 2026);
-reading a .coverage file works everywhere.
