How prompt work the new Claude
Step 1: Replace “review” with the actual scope.
Before (4.6): Claude would try to understand what you meant, with freedom.
After (4.7): Does exactly what you typed.
Old:
Review this contract.
New:
Review this contract. Flag risks per clause. Rate severity 1-5.
Suggest one rewrite per risky clause. Return as a table.
The fix: Name every output. Name the order. Name the boundaries.
Step 2: Define length.
Before (4.6): Roughly the same length each time, regardless of input size.
After (4.7): Sizes the answer to what it thinks the task is. Long input + “summarize” = long summary. If you want a short summary, be explicit.
Old:
Summarize this report.
New:
Summarize this report in exactly 5 bullet points.
Each bullet under 15 words. First word of each bullet: an action verb.
The fix: Name the format and the cap.
Step 3: Use positive instructions only.
Negative instructions stick to the literal sentence on Claude 4.7.
They don’t work. (it’s kinda funny to say “don’t be negative” which is negative).
Old:
Don't use jargon. Don't use buzzwords. Don't sound like a marketer.
New:
Write in plain English a 16-year-old could read aloud.
Use short, concrete words: simple, specific, real.
Replace "leverage" with "use." Replace "scalable" with "works at any size."
Step 4: Use action verbs only.
Each action verb tells Claude 4.7 to ship something specific. And 4.7 loves that.
Old:
Can you help me with the email?
New:
Go to my Gm ail. Find [contact] and read our last conversation.
Write the answer email. Final draft. Send-ready.
Goal: book a meeting with the CRO of Snowflake by Friday.
Length: under 90 words.
Tone: confident, casual, specific.
Step 5: Calling “tools”.
A “tool” is, for example, when Claude goes to the web to find information.
Before (4.6): Called tools frequently.
After (4.7): Calls fewer tools. Reasons more between calls.
The fix:
If quality is good, trust the new default.
If you want more tool use, prompt explicitly. For example:
Use web search aggressively. Verify every claim with at least 2 sources.
Step 6: The new tone.
Before (4.6): Warmer. Validation-forward. “Great question!” energy. More emojis.
After (4.7): More direct. Less validation. Almost zero emojis.
The fix (if you want a warmer tone back):
Use a warm, conversational tone. Acknowledge the user's framing before answering.
Even better: paste 2-3 sentences in the voice you want, and tell Claude to match the rhythm of those examples.
Step 7: Add “go beyond the basics” on creative tasks.
This phrase is from Anthropic’s own Claude 4.7 doc. It pushes 4.7 past the literal minimum on creative or open-ended work. Feels great when you finally try it!
