Anthropic released a 31-page PDF prompting guide.

I turned it into 9 tips you can read in 60 seconds:

_

Prompt tip 1. Name the Output, Not the Task.

☑ Replace "review" & "help" with the real task.

☑ Specify the format → table, bullets, JSON, doc.

☑ Vague verbs get vague drafts. Name the thing.

_

Prompt tip 2. Define the Length Up Front.

☑ Set the exact count → "5 bullets," "180 words."

☑ Name the first word of each line → verb, noun.

☑ Add "No preamble. No recap. No filler."

_

Prompt tip 3. Flip Every "Don't" Into a "Do."

☑ Find every "don't" & "avoid" in your prompt.

☑ Rewrite each as a positive instruction.

☑ 4.7 reads literally. Tell it what to write, not dodge.

_

Prompt tip 4. Lead With Action.

☑ Remove "Can you help me with..."

☑ Start every line with: Write. Find. Draft. Send.

☑ Politeness costs tokens. Action ships work.

_

Prompt tip 5. Force Maximum Reasoning.

☑ Select Opus 4.7 with Adaptive thinking on.

☑ End your prompt with "Think before answering."

☑ Opus 4.7 reasons on demand, not by default.

_

Prompt tip 6. Add "Go Beyond the Basics."

☑ Paste this exact phrase on every creative task.

☑ Set the bar: "Polish like a real client deliverable."

☑ Ban the lazy defaults → "no purple gradients."

_

Prompt tip 7. Upload Your Voice.

☑ 2-3 sentences written exactly how you sound.

☑ Tell Claude: "Match the style of these examples."

☑ Save them in 'about-me' file. Reuse them forever.

_

Prompt tip 8. Control Tools On Purpose.

☑ For research → "Use search. 2+ sources/claim."

☑ For speed → "Answer from training. No search."

☑ Claude Opus 4.7 calls fewer tools by default.

_

Prompt tip 9. State the Goal Before the Task.

☑ Open with "Goal: [what winning looks like]."

☑ Name audience → "for a CRO, not an engineer."

☑ A prompt without a goal is a wish. State the win.
