Write sales AI prompts that produce reviewable work

Better prompts define the task and the boundary

"Act as a world-class salesperson" does not tell the assistant what evidence to use or what it must not invent. A useful prompt defines the task, sources, audience, output, uncertainty behavior and prohibited actions.

Tone matters after those pieces are clear. A polished output with unsupported buyer claims is still a failure.

The six-part structure

1. Task: prepare a follow-up draft, not send a message.
2. Sources: use only supplied permitted notes and approved scope.
3. Audience: the buyer, not an internal manager.
4. Format: recap, unresolved question and next action.
5. Uncertainty: mark missing timing or ownership for review.
6. Boundary: no invented promises, pricing or actions.

A complete example

Prepare a buyer-facing follow-up draft from the attached permitted notes and current approved service description. Use a short recap, one unresolved question and the agreed next action. Preserve the buyer's qualifiers. If no action was agreed, label your next step as a suggestion. Do not invent budget, dates, authority, discounts or product capabilities. Return a draft only and list factual items the rep must verify before sending.

Worked failure and correction

A vague prompt says "Write a persuasive follow-up that moves this deal forward." It may turn buyer interest into urgency. The bounded version says what the rep actually needs and how to handle missing facts. If the assistant still invents a date, reject the output and inspect whether the source or instruction was ambiguous.

Test before reusing

Keep a small set of complete notes, incomplete notes and contradictory notes. Run them after changing the prompt, source material or model configuration. Record whether the output preserves unknowns and respects the prohibited actions.

Do not tune only for the perfect example. The difficult examples show whether the prompt is useful when reps are busy and notes are imperfect.

Keep the prompt maintainable

Name the owner, version and intended task. Store current approved prompts where reps can find them. Retire obsolete versions and explain material changes. Prompts are not access controls; permissions and action boundaries require actual configuration and testing.

Pair this with follow-up review and tool evaluation.

Build a prompt test set from three synthetic cases

Case one contains a clear buyer problem and an agreed next action. Case two contains the same problem but no date or owner. Case three includes contradictory notes about whether the buyer requested a proposal. Write expected behavior for each case before running the prompt.

For the complete case, the draft should preserve the agreement. For the incomplete case, it should ask for confirmation. For the contradictory case, it should flag the conflict rather than select the version that sounds most sales-ready. Save the outputs and reviewer decisions so a future prompt change can be compared honestly.

A prompt change checklist

• The task and audience are still explicit.
• Approved source instructions have not been removed.
• Unknown and contradictory input behavior still works.
• Prohibited promises and actions remain excluded.
• The reviewer can inspect the facts behind the output.

Ask a rep who did not write the prompt to use it on a permitted example. If they must supply a long verbal explanation to get a useful result, improve the input instructions or workflow. A reusable prompt should make the task easier to perform consistently. It should not depend on the original author's memory of which assumptions the assistant is allowed to make.
