Diagnostics and navigation

Diagnostics run against the current in-memory editor buffer and publish stable VB..., VBA..., and UserForm codes with source xlflow. This means they can warn you before you save a file or open Excel. Use the Problems panel to jump to a line, hover for the explanation, and apply a Quick Fix where one is offered.

Registered VB... and VBA... diagnostics link from the Problems panel to the matching entry in the generated diagnostic catalog. The extension reads rule metadata from xlflow rules --json and offers an inline-suppression Quick Fix only when that installed xlflow version marks the rule as suppressible. If metadata cannot be loaded, its schema is unsupported, or the ID is unknown, the extension does not guess and omits the action.

Project-wide checks still run from xlflow lint and xlflow analyze; they include filesystem and preflight rules that cannot be inferred safely from one unsaved document. Treat a clean editor as a good first signal, then run the project checks before push. Use Go to Definition, Find References, symbols, and rename for project navigation.
