# List the rule namespace for a deal

Every name a rule condition may read, with what it resolves to on THIS deal - average monthly revenue, NSF count, positions, tax-year figures, credit score and tradeline counts, extraction fields, and the deal's own cells. Reach for it before writing a condition, to see the numbers a threshold would be compared against.

Access class: `def:read`.
