Common Pitfalls

Avoid these common prompt issues:

Too Many Steps

# ❌ Too complex for a single prompt
Create account, search products, compare 5 items, read reviews,
check shipping options, apply coupons, complete purchase,
write product review, check order status, and modify shipping address

Ambiguous Instructions

# ❌ Unclear
Find something interesting and do something with it

# ✅ Clear
Find the "Featured Products" section and click on the first item

Missing Context

# ❌ Assumes too much
Submit the form
(Which form? What data?)

# ✅ Provides context
Fill out the newsletter signup form with email test@example.com and submit it
