Built-in diagnostics and user rules

Revit Linter can check a model in two complementary ways.

	Built-in diagnostics	User rules
Best for	Common model-quality problems	Project and company requirements
Setup	None	YAML files in the configuration folder
Maintenance	Updated with Revit Linter	Owned and edited by your team
First step	Enable a diagnostic and run it	Copy an example and change one condition

Start with built-in diagnostics

Built-in diagnostics are ready immediately. Open the Diagnostics pane, select the checks that fit the current model, then run them from Diagnostic results. This is the quickest path to a useful report and does not require YAML knowledge.

Add a user rule when the requirement is yours

A user rule describes:

• code — a stable unique identifier;
• description — the name shown in the interface;
• severity — message, warning, or error;
• take — which Revit elements to inspect;
• check — what a valid element must satisfy.

The check expression describes the valid state. Every element selected by take for which check returns false becomes a finding.

Follow Create your first rule for a small editable example. Use User diagnostics when you need the complete field reference, formulas, visualizations, or fixes.
