brainstorming
You MUST use this before any creative work - creating features, building components, adding functionality, modifying behavior, or planning anything new, in software or out of it (a talk, a business, a renovation).
marketing-mindsetUse when a user asks how to win first customers, whether doing X will produce Y, how to write an ad or judge a marketing test — a marketer's decision framework, not a tactic library.

Most agents answer a marketing question by reaching for a tactic: a hook template, a funnel diagram, a list of channels. That produces plausible text and no decision. This skill supplies the layer underneath — how an experienced marketer decides what to do, what volume a test needs before its result means anything, and when to kill a channel instead of optimizing it.
It is a pure reasoning skill. It reads the user's own context (product, offer, audience, budget, channel data) and returns a verdict with the reasoning attached, including the verdict "this is not worth doing". The full version lives at the source repository; this entry is adapted for this catalog.
Marketing is an exchange. Every action must trade for something — money, clear prospects, a realistic chance of revenue, or something applicable immediately. If the exchange is zero, say so and name the missing half. This is the filter that kills most requests before any tactic is chosen.
Ask for the two numbers that decide everything else: how many paying clients exist today, and what channel produced them. With zero clients, the only honest advice is hand-won outreach plus the founder using their own product. Money is a scaling instrument, not a starting instrument — spend at zero clients buys noise.
Benchmark against companies working the same audience right now and making money from it, not against well-known companies with no current motion. Recently founded, growing competitors produce the most copyable hypotheses because their moves are short and recent. Treat ranking lists, launch sites, and influencer endorsements as advertising, not as truth, and treat any report older than six months as history.
Below a floor you are measuring randomness, not the market. State the floor before the test starts, and refuse to draw a conclusion below it.
| Channel | Minimum volume before a verdict |
|---|---|
| Cold email, deliverability smoke test | 50–100 sends |
| Cold email, reply-rate comparison | ~1,500–2,000 sends per variant |
| Subject-line test | 100–500 sends per version |
| Landing page smoke test | 100–200 targeted visitors |
| Paid ad | 1–3x target CPA over 48–72 hours |
| Strict A/B test | ~10,000 visitors and 300+ conversions per variation |
Decide in advance what result means keep, what means re-hook, and what means stop — and hold the decision at the pre-declared volume. Killing a channel that cannot pay back within the stated budget is a result, not a failure, and it frees the capacity that a weak channel quietly consumes.
Attention splits in two: a rational part that can be reached with numbers and a part that responds only to feeling. Both need to be addressed. In visuals, the eye sees sharply only in a small focal area, so a creative needs a background, a scene, one hero subject, and implied movement. In copy, the reader is thinking about themselves — content that lets them keep doing that outperforms content about the product.
End with a decision: run it, change one variable and rerun at the stated volume, or stop and do something else. Attach the reasoning and the number that settles the question. When nothing has worked after the obvious options are exhausted, say that plainly rather than producing another reasonable variant — reasonable variants are the ones everyone already tried.
The response does not start with subject lines. It asks how many emails were sent. At 300 sends, 0.4% is one reply; the correct answer is to keep sending to the pre-declared floor before changing anything. At 4,000 sends across two variants, the reply rate is a real signal, and the useful move is offer and targeting, not wording.
The skill checks the spend against the target CPA and the pre-declared window. If $2,000 is below 1x target CPA and the campaign has run under 72 hours, the honest answer is that the data cannot support a decision yet. If spend has exceeded 3x target CPA with no conversion path, the answer is to stop and name what the campaign proved — that this channel, at this offer, does not pay back.
The skill asks for the client count and the offer. With zero clients, it redirects to hand outreach first and treats the page as supporting evidence rather than the acquisition engine. With paying clients, it writes the page around the offer that is already converting, in the customer's own language pulled from their replies.
