## Your task
Write a campaign brief for [PRODUCT OR SERVICE] at a mid-sized law firm. Audience: clients, partners and associates. Include objective, single-minded message, insight, channels, deliverables, budget of [BUDGET], timeline, mandatory elements and how success is measured through matter turnaround and billable utilisation. Respect client confidentiality, professional-conduct rules and jurisdiction (the output is a draft for a qualified lawyer to review, not legal advice).
## What matters in Legal
- How customers decide: clients choose on expertise, trust, responsiveness and fees; companies want predictable costs and plain-language advice.
- Rules and standards that usually apply: client confidentiality and privilege; bar council and professional-conduct rules; the law of the relevant jurisdiction; limitation periods and court deadlines; conflict checks; every output is a draft for a qualified lawyer, not legal advice.
- Timing and seasons: hearing dates and court calendars; limitation deadlines; clients' financial year-end.
- Words people in this field use: matter; brief; pleading; affidavit; clause; indemnity; jurisdiction; precedent; retainer.
- Rules differ by country. If I have not said where I work, ask me, and do not present one country's law as if it applied everywhere.
## How to work through it
1. Define the objective and how it will be measured.
2. Find the customer insight and write one single-minded message.
3. Choose channels and deliverables.
4. Set budget, timeline and mandatory elements.
5. Check the brief against the rules we must respect.
## What to deliver
- Campaign brief
- Deliverables list
- Success measures
## Rules
- Make every point specific to my situation and my industry; replace generic advice with detail that fits.
- Use plain language, short sentences, and tables where they make the answer easier to scan.
- Use only the facts I give you. Do not invent figures, laws, sources or quotes. Mark anything you had to assume with "Assumption:".
- If something important is missing, ask me up to 3 short questions before you start.
## Before you answer
Check your draft against this list and fix anything that fails:
- Every claim can be backed up, and the copy speaks to clients, partners and associates in words they use.
- It is written for a mid-sized law firm; nothing in it would read the same for any other business.
- Nothing in it breaks client confidentiality, professional-conduct rules and jurisdiction (the output is a draft for a qualified lawyer to review, not legal advice).
- Every item under "What to deliver" is included.

Why this prompt works
The “Campaign brief” prompt tells the assistant exactly what to hand back: campaign brief; deliverables list; and success measures. It makes the assistant work through 5 steps in order, starting with "define the objective and how it will be measured", instead of jumping straight to an answer. Before replying, the assistant checks its draft against 4 tests and fixes anything that fails.
This version is written for a mid-sized law firm, so the assistant keeps client confidentiality, professional-conduct rules and jurisdiction (the output is a draft for a qualified lawyer to review, not legal advice) in mind and judges the result by matter turnaround and billable utilisation. If an important detail is missing, it asks you up to 3 short questions before it starts.
How to get the best answer
- Fill every bracket with real detail: [PRODUCT OR SERVICE], [BUDGET] should hold real names, numbers and dates, not placeholders.
- Paste real material: where the prompt asks for notes, data or text, paste the actual content rather than a summary.
- Refine in the same chat: ask "make it shorter", "turn it into a table" or "add more detail on step 2".
- Check the result: review it against what you know about matter turnaround and billable utilisation before you share it.
