Useful depth, not content for content's sake.

Answer first. Provenance stays attached.
Use primary sources. Manufacturer/government evidence leads technical claims where available.
Keep price bases separate. Material-only and complete-project observations answer different questions.
Preserve uncertainty. A planning estimate is not a formal quote or site diagnosis.
Build tools when tools are better. Geometry and quantity questions should lead into calculation, not filler prose.
