 Example run from the project root:
 
 ```bash
-npm exec prisma validate
+npx prisma validate
 # → Works as expected
 ```
 
 Run from a subdirectory (fails):
 
 ```bash
 cd src
-npm exec prisma validate
+npx prisma validate
 # → Error: Could not find Prisma Schema...
 ```
 
 To fix this, you can use the `--config` flag:
 
 ```bash
-npm exec prisma -- --config ../prisma.config.ts validate
+npx prisma validate --config ../prisma.config.ts
 ```
