+# Simplify an interface
+
+Remove obstacles between the user and the main task without removing necessary capability.
+
+## Find the excess
+
+- Identify the primary goal and the information required to complete it.
+- Remove repeated copy, duplicate actions, decorative noise, and containers that do not clarify grouping.
+- Reduce unnecessary variation in colors, type sizes, button styles, spacing, and surface treatments.
+- Prefer one obvious primary action and a small number of clearly subordinate actions.
+- Use progressive disclosure for advanced or infrequent controls, but keep essential information visible.
+
+## Preserve clarity
+
+- Do not hide required actions behind mystery interactions.
+- Do not remove labels, focus states, accessibility semantics, error messages, or recovery paths.
+- Do not flatten genuinely complex information until it becomes harder to understand.
+- Prefer spacing and alignment over nested cards; prefer plain language over explanatory copy.
+
+Verify that the simplified result still supports the complete task, including its important states, at the relevant screen sizes.
