Claude prompts I keep reusing
Personal pack. Not authoritative, just what's working for me as of 2026-05.
Re-read mode
"Read this URL as context. Summarise the key claims in 3 bullets. Then ask me one question that exposes the weakest claim in the summary."
Why it works: the summary forces compression; the one question forces critical engagement. The combination prevents the "Claude says yes to everything" failure mode.
Decision mode
"You're an opinionated engineering manager. The context is at
. I'm trying to decide whether to . Recommend an action, then explain the single biggest tradeoff. No hedging."
Why it works: "opinionated EM" anchors the voice. "Single biggest tradeoff" forces ranking. "No hedging" closes the escape hatch.
Audit mode
"List every assumption in this doc that isn't backed by evidence elsewhere in the hub. For each, suggest what evidence would make the assumption checkable."
Why it works: the second clause keeps it from being a list of nitpicks. Each item ends with a concrete way to validate.
Reading list mode
"From
, what's the ideal reading order if I have only 15 minutes? Order them by 'most value gained from reading first'."
Why it works: bundles have reading orders built in (the analyser produces one) but they optimise for "complete understanding," not "best 15-min." Asking for the time-boxed order is different.
Counterpart mode
"You're the smartest person who disagrees with this thesis:
. The context is at . Write the strongest version of their argument."
Why it works: forcing the opposite framing reveals which parts of my thesis are durable and which parts only hold because I haven't seen the counter-argument.
Pre-write mode
"I'm about to write a doc with the working title
. The audience is . The context is at . Before I write, what are three questions you'd want me to answer in the doc, in priority order?"
Why it works: writing-question-driven docs land harder than writing-topic-driven docs. The pre-write prompt produces the questions.
What I'm not using
- "Be concise." Useless — Claude is already calibrated for length to context. Better to say "Answer in
sentences" with a specific number. - "Be honest." Implies otherwise. The model is mostly honest; ask better questions instead.
- Roleplay prompts that anchor to a famous person. They make the answer feel persona-shaped instead of evidence-shaped.
