+# Response Format Principles
+
+> Consistency is key - choose a format and stick to it.
+
+## Common Patterns
+
+```
+Choose one:
+├── Envelope pattern ({ success, data, error })
+├── Direct data (just return the resource)
+└── HAL/JSON:API (hypermedia)
+```
+
+## Error Response
+
+```
+Include:
+├── Error code (for programmatic handling)
+├── User message (for display)
+├── Details (for debugging, field-level errors)
+├── Request ID (for support)
+└── NOT internal details (security!)
+```
+
+## Pagination Types
+
+| Type | Best For | Trade-offs |
+|------|----------|------------|
+| **Offset** | Simple, jumpable | Performance on large datasets |
+| **Cursor** | Large datasets | Can't jump to page |
+| **Keyset** | Performance critical | Requires sortable key |
+
+### Selection Questions
+
+1. How large is the dataset?
+2. Do users need to jump to specific pages?
+3. Is data frequently changing?
