25 AI Agent Prompts (Task Briefs) That Actually Work

An AI agent does what its brief says, including the parts you forgot to say. Owners who complain that agents are unreliable usually wrote three-word instructions — "handle my inbox," "research competitors" — and received exactly the behavior that brief deserved. The fix is a complete task brief: goal, context, constraints, output, and approvals. Below is the five-part template plus twenty-five ready-to-adapt briefs across sales, operations, and admin, each written so a non-technical owner can fill in the brackets in minutes.

If you have not chosen which tasks to delegate yet, start with your first AI agent to-do list, then return here to brief each one. When a brief becomes a recurring responsibility, promote it into a full one-page AI agent SOP.

Key takeaways

• A task brief has five parts — goal, context, constraints, output, approvals — and takes about five minutes to write.
• Be strict about boundaries (which systems, what needs approval) and loose about method (let the agent pick its working order).
• Every brief below needs approval-tier language before it touches customers, money, or records of account.
• Add one worked example of good output to any brief the agent gets wrong twice.
• Review briefs monthly: stale permissions and outdated examples cause more errors than the model does.

The five-part brief template

Copy this skeleton for every task. Fill the brackets, delete nothing.

1. Goal. One sentence stating the finished state. Not "work on," but "produce": a triaged inbox, a booked appointment, a reconciled list.

2. Context. Where the agent works and what it may read: the named inbox, the folder path, the CRM view, the date range. Include background the agent cannot guess, such as current priorities and excluded accounts.

3. Constraints. Time boxes, budgets, off-limits systems, tone rules, and compliance lines. This section carries the weight: "never contact anyone who asked to be removed," "quotes above $500 need approval," "do not open the payroll folder."

4. Output. The exact deliverable and its format: a summary under 150 words with links, a table with named columns, a draft saved but never sent. Specify where the output goes.

5. Approvals. Which tier each action sits in: automatic, notify, or requires approval, with the named approver and the response window. Both ChatGPT Dots and Claude Cowork provide per-task approval controls, so write the brief to match the mechanism: "save the draft automatically, send only after approval from [name] within four business hours."

Sales and follow-up briefs

These seven briefs cover pipeline work. All of them touch prospects, so every send step below sits in the approval tier until the brief has run cleanly for at least two weeks.

1. Morning lead triage. "Each weekday at 7:30 am, review new leads in [CRM view] from the last 24 hours. Score each 1 to 5 using [your qualification questions], flag matches against our ideal-customer notes in [file], and produce a table with name, source, score, and recommended first action. Do not contact anyone."

2. Pre-call research. "Before each sales call listed in [calendar] today, compile a half-page brief: company background, likely needs, our relevant past work, and three discovery questions. Cite every factual claim with its source link."

3. Quote follow-up drafter. "Find quotes older than [N] days in [system] with no reply. Draft one follow-up per quote referencing the scope and offering two call windows. Queue for approval. Never send, discount, or invent availability."

4. No-show recovery. "Each morning, list yesterday's no-shows from [calendar]. Draft a rescheduling message for each, personalized with the missed service. Queue for approval. Mark contacts with two consecutive no-shows as do-not-chase."

5. Review request routing. "Each Friday, list this week's completed jobs in [system] with technician and customer contact. Draft a review request naming the technician, with a direct review link. Queue for approval. Exclude jobs with open complaints."

6. Competitor watch. "Weekly, check [named competitor sources] for pricing, service, or hiring changes. Summarize only what changed since last week with dates and links. If nothing changed, say so in one sentence."

7. Pipeline hygiene. "Every Monday, scan [pipeline stage] for deals untouched [N] days. For each, note last activity, deal value, and whether it should advance, get a task, or close as lost with a reason. Apply nothing; the owner decides."

Operations briefs

Operations tasks suit agents well because they are high-volume and rules-bound — the standard workload for an AI internal assistant. Intuit's 2026 data shows 78 percent of US AI users report improved productivity, and operations is where those hours usually come from.

8. Inbox triage. "Twice daily, sort [inbox]: urgent customer issues to the top with a one-line summary each, vendor and internal mail into folders per [rules], promotions out. Draft replies only for routine confirmations; queue everything customer-facing for approval."

9. Schedule assembly. "Each evening, build tomorrow's schedule from [calendar plus job system]: confirm crew assignments, flag gaps and double-bookings, and list customers still needing confirmation. Alert [name] about conflicts; the rest goes in the morning summary."

10. Document collection chase. "For onboarding files in [checklist], identify customers missing items over [N] days. Draft one reminder each listing exactly what is missing and how to send it. Queue for approval."

11. Meeting notes to tasks. "After each meeting in [calendar], read the notes or transcript in [location], extract decisions and action items with owners and dates, and post them as drafts. Flag any item with no owner for the manager to assign."

12. Inventory or supply check. "Weekly, compare stock in [system] against minimums in [file]. List items below minimum with usual supplier and last price. Draft the reorder message for approval. Never place orders."

13. Subcontractor confirmation. "Two days before each scheduled subcontractor visit in [calendar], draft a confirmation restating date, time, site address, and scope reference. Queue for approval. Report any subcontractor late twice this month."

14. End-of-week operations summary. "Fridays at 4 pm, produce a one-page summary: jobs completed, jobs carried over, callbacks and complaints, crew hours from [system]. Under 300 words with a table. Send to [name] automatically."

15. SOP lookup assistant. "Answer staff questions using only [named SOP documents]. Quote the relevant section with document name and version date, and say plainly when no SOP covers the question. Log unanswered questions weekly."

Admin, finance, and hiring briefs

Money and people decisions need the tightest approval tiers in this article: the agent prepares, humans decide.

16. Invoice triage. "Weekly, list unpaid invoices in [accounting system] over [N] days old with amounts and contacts. Draft one reminder per invoice in our standard wording. Queue for approval. Never add fees or contact anyone in active dispute — list those separately."

17. Expense sorting. "Monthly, categorize card transactions in [export] against our chart of accounts in [file]. Mark anything ambiguous with your best guess noted beside it. Produce the table for the bookkeeper."

18. Timesheet chase. "Each Monday, list staff with missing hours for last week in [system]. Draft one reminder per person, batched for the manager to send. Report repeated patterns monthly."

19. Applicant first sort. "For open role [title], read applications in [location] against the must-haves in [file]. Sort into yes, maybe, and no with one quoted reason each. Do not contact candidates. Flag accommodation requests for human handling immediately."

20. Interview scheduling. "For candidates marked yes in [location], offer three windows from [calendar] by drafted message, queued for approval. On confirmation, create the event with the interview template attached."

21. Reference and credential checklist. "For each hire marked proceeding in [tracker], list outstanding credentials, references, and documents with due dates. Draft chase messages for approval. Never judge a reference's content — report facts only."

22. Monthly numbers pack. "On the [N]th of each month, assemble revenue, pipeline value, close rate, average job value, and review count from [named systems] into one table beside last month's figures. Flag any move over [N] percent. Draft only."

23. Vendor bill comparison. "Quarterly, compare vendor bills in [folder] against contract rates in [file]. List discrepancies with amounts and invoice numbers, plus a drafted query per vendor for approval."

24. Content draft from job notes. "From this week's completed-job notes in [location], draft two short social posts and one review-response template in our voice per [style notes]. Queue for approval. Never invent customer quotes or results."

25. Weekly personal digest. "Fridays, summarize my week from [calendar and task system]: completed, slipped with new dates, and the three most important Monday items with reasoning. Under 250 words."

Making the briefs stick

Three habits separate owners whose agents improve from owners whose agents decay. First, version your briefs: save each as a dated document noting what changed and why. Second, log corrections for two weeks whenever a task starts or changes. Third, review access quarterly, since leavers, role changes, and new tools silently change permissions.

FAQ

What makes a good AI agent brief different from a chatbot prompt?

A chatbot prompt asks for text, while an agent brief authorizes action: it names the goal, the systems and files the agent may touch, the constraints and approval tiers, and the exact output format. The five-part template in this article — goal, context, constraints, output, approvals — takes about five minutes to fill in and prevents most overreach. Vague briefs are the leading cause of agent mistakes owners complain about.

How specific should my instructions be?

Specific about boundaries, loose about method. Name the exact accounts, folders, and record types allowed, state what needs approval, and describe the finished product precisely. Let the agent choose its own working order within those rails. Over-scripting each step wastes the agent's ability to adapt, while under-specifying access is how drafts get sent as final messages.

Should I let the agent act without approval?

Allow unsupervised action only for reversible, low-consequence work such as drafting, researching, and organizing. Anything customer-facing, financial, or destructive — sending messages, issuing refunds, deleting records — should require approval or a notification window. Products like ChatGPT Dots and Claude Cowork both ship per-task approval controls for exactly this reason.

How do I fix an agent that keeps getting a task wrong?

Rewrite the brief before blaming the tool: add one worked example of correct output, narrow the allowed sources, and move the failing step into the approval tier. Keep a log of corrections for two weeks and look for patterns rather than patching single errors. Persistent failure on a well-briefed task usually means the task needs restructuring, not better wording.
