 ## Optimization Approaches
 
+### 0. Strip Redundant `action` Property (~2 KB savings)
+
+The `action` property in each event action object duplicates information already present as the object's key:
+
+```json
+{
+  "issues": {
+    "opened": {                    // <-- action name is already the key
+      "action": "opened",          // <-- redundant, can be stripped
+      "bodyParameters": [...]
+    }
+  }
+}
+```
+
+| Property | Occurrences | Bytes per occurrence | Savings |
+|----------|-------------|---------------------|---------|
+| `action` | 141 | ~15 bytes | ~2 KB |
+
+**Complexity:** Very low - add `action` to `EVENT_ACTION_FIELDS` strip list
+
+---
+
 ### 1. Short Property Names (~80 KB savings, ~17% reduction)
 
 Replace verbose property names with single-character keys in the minified output.
