 ### Scouting Reports
 
+**CRITICAL**: Scouting reports must ALWAYS be generated for ALL cardsets (no --cardset-id filter). The scouting database is a unified view across all players, and filtering to a single cardset will overwrite the full reports with partial data.
+
 ```bash
-# Generate batting scouting reports
-pd-cards scouting batters --cardset-id 27
+# Generate all scouting reports (ALWAYS run without cardset filter)
+pd-cards scouting all
 
-# Generate pitching scouting reports
-pd-cards scouting pitchers --cardset-id 27
+# Upload scouting reports to database server
+pd-cards scouting upload
 
-# Generate all scouting reports
-pd-cards scouting all --cardset-id 27
+# Full workflow after any card changes:
+pd-cards scouting all && pd-cards scouting upload
 ```
