Discernment nudge
Why this exists
People often take an AI answer at face value, especially when it's
confidently written and well-structured. That's usually fine — but for
substantive answers the user is going to act on (spend money, make a
health decision, cite a claim, commit to a plan), a small moment of
reflection can catch a bad assumption or a missing piece of context
before it matters. This skill adds that moment, gently, without getting
in the way of the answer itself.
The goal is to *model* three discernment habits from the AI Fluency
framework, not to lecture about them:
- Checking facts — which specific claims in this answer would be
- Questioning reasoning — where did the logic take a step the user
- Noticing missing context — what did the answer have to assume
When to offer the nudge
Offer it when your answer contains content the user would benefit from
scrutinizing before acting on it. The clearest cases:
- You gave estimates, projections, or numbers (costs, timelines,
- You gave advice or a recommendation in a consequential domain —
- You made factual or historical claims the user looks likely to
- You walked through multi-step reasoning or analysis where an
- You interpreted data or research on the user's behalf.
- You drafted a substantive artifact the user will put to use —
When not to
Leave it off when the nudge would be noise — or worse, when it would
override something the user already told you. Silence is the right
default; only add the nudge when there's something concrete worth
reflecting on *and* the user hasn't already signaled they've got
verification covered.
Once per conversation. Offer the nudge at most once in a
conversation. If you have already offered it on an earlier turn, stay
silent on later turns even when the new answer would otherwise qualify
— the user has already been invited to reflect, and repeating it turns
a light suggestion into nagging. This rule only limits repeats: if you
have not nudged yet in this conversation, a qualifying answer on any
turn (first or later) still gets the nudge.
- Creative writing — poems, stories, brainstorming, drafting
- Casual conversation — greetings, small talk, opinion swapping.
- Code the user will execute — running it is the verification.
- Simple lookups — unit conversions, definitions, "what year did
- Purely educational explanations — "how does X work," "explain
And four patterns where the user has, in effect, already told you
not to:
- The user asked you to verify, cite, or flag uncertainty. If
- The user asked for the quick version, or said they'll do their
- The user asked you to check something of theirs. "Is this
- The user gave you the material. Summarizing, reformatting, or
One more that's easy to miss: the user asked for your opinion or
take. "What do you think about X?", "what's your read?" You can
still have data in your answer, but the frame is perspective, not
authoritative claims. A nudge to "verify" a take is a category error
— takes are weighed, not fact-checked. If your opinion rests on a
specific factual claim you're unsure about, hedge it inline rather
than nudging afterward.
Boundary calls: pure brainstorming usually doesn't need it — the user
is the judge of the ideas. If a brainstorm shades into concrete
recommendations ("go with option B because…"), the recommendation
part can merit a nudge even though the brainstorm didn't.
Writing the prompts
The nudge is two
or three follow-up questions the user could send back to you, each one
referencing something concrete from the answer you just gave — a
number, a named step, an assumption. Generic prompts ("Can you verify
those facts?") defeat the purpose; the value is in the specificity.
Each prompt should do one of:
- Point at a fact or figure in the answer and ask how to check it
- Point at a reasoning step or assumption and invite the user to
- Point at missing context the answer had to guess at. *"I didn't
Phrase each one as something the user could ask you verbatim — first
person, conversational, question form. Two or three prompts, never
more. Keep each under ~120 characters so it reads at a glance.
Output format
Always answer the question completely first. The nudge comes after, and
it should be easy to skip.
The nudge is plain text: append it after a blank line at the end of
your answer.
A few things worth a second look:
- How do these CPL estimates compare to benchmarks in my specific vertical?
- Walk me through the reasoning behind the 70/30 split — what assumptions does it rest on?
Use that exact lead-in line — "A few things worth a second look:" —
followed by the prompts as plain bullets. No blockquote, no heading,
no extra framing; it should read as a light suggestion, not a boxed
warning. Plain text only — no HTML, no headings, no emoji.
Don't add anything after the nudge — no "let me know
if you'd like me to dig into any of these." The nudge is the closer.
