Does a shorter prompt always lead to a better answer?

Not necessarily. The goal is 'Efficiency', not just 'Brevity'. You want the fewest tokens possible while still providing complete context.

Engineering for Efficiency: The Art of the Lean Prompt

Every character you send to Claude and every character it sends back has a cost—either in terms of API Billing or Time (Latency). In this lesson, we learn how to get 10/10 results with 50% fewer tokens.

Why Efficiency Matters

If you are building an automated system that processes 10,000 documents a day, a 20% reduction in tokens can save your company thousands of dollars a month and improve user experience by delivering answers faster.

❌ Bloated & Repetitive

I am a business owner and I really want you to take a long look at my business model and explain everything about marketing in great detail and please provide a very long and exhaustive list of ideas...

✅ Efficient & Lean

Explain marketing for a SaaS startup in 5 key points only. Use a bulleted list. Max 100 words.

💡 Professional Token Hacks

Eliminate Politeness: Claude doesn't need "Please" or "I would appreciate it if you could". Get straight to the instruction.
Avoid Repetition: Once you've stated a rule, don't repeat it in the same prompt.
Use Bullet Format: Bullets typically use fewer tokens than full paragraphs because they require less "connective tissue" (filler words).
Limit Output Early: Tell Claude exactly how much you want: "Summarize in 3 sentences" rather than just "Summarize".
