What it does
In the author's own words, from each skill's SKILL.md.
-
case-study
Case Study. Turns the first customer into proof, with their permission. Once the product has shipped, it writes a short before-and-after from their real numbers and their real words, and keeps it marked as a draft until they have approved that exact text in writing. Change a word and it asks again. Use when the user says "case study", "testimonial", "customer story", "get a quote from them", "wri…

demo-builder
Demo Builder. Builds a demo showing how your product solves the problem, before the product exists. Turns a small spec into one self-contained HTML page that runs anywhere with no server: sample records, one button, every row moving through its statuses and a total counting up, with a banner that always says it is a demo with sample data. Claude can then make it look and behave more like the real…

follow-up
Follow-Up. Keeps the deal moving. Tells you who is due today after a pitch or an offer, drafts the next note (a bump, something useful, a last note), waits for your yes, logs it, and stops at the first "no", the moment a demo is booked, after 3 follow-ups or after 30 days. Logs their replies and knows when it's your turn. Use when the user says "follow up", "who do I need to follow up with", "the…

launch-planner
Launch Planner. Plans the launch once it is paid for. Works backwards from the earliest date you promised a paying customer: requirements confirmed, feature complete, customers testing, fixes, first ship, then the rest. The public launch comes last, behind a gate that stays closed until someone has the product, nobody is late, and everything they paid for is built. Use when the user says "launch…

market-researcher
Market Researcher. Finds problems businesses already pay thousands to solve. Looks for money that is already leaving their accounts: vendors, agencies, outsourced services and salaried jobs that exist only because of one painful problem. Builds a table of the problem, who pays and what they pay today, with a source for every number or a clearly marked estimate with its working, then helps you pic…

objection-handler
Objection Handler. Answers every objection, and knows a no when it hears one. Matches what they said ("it isn't built yet", "what if you never ship it", "why pay up front", "too expensive", "I need to ask my CFO") to an honest answer filled in from your own terms, and shows why it works. A real no gets no answer at all: it stops the deal for good. Every answer is a draft for your yes. Use when th…

offer-builder
Offer Builder. Writes the offer they can say yes to. One page: the problem in their own numbers, what they get, the price, the date it ships, and the way out, with the plain statement that it isn't finished yet. A lint refuses an offer that leaves any of that out or that leans on fake urgency, made-up proof and promises nobody can keep. Every offer waits for your yes. Use when the user says "writ…

pre-sale
Pre-Sale. Gets customers to pay up front, and uses what they ask for to build the exact product. Sets honest terms (it isn't finished, the date it ships, how they get their money back), checks them, prepares a Stripe Payment Link in your own account for one buyer, logs real payments, and tells you when enough companies have paid to call it validated. Then it holds you to the date: it flags every…

pricing
Pricing. Sets the price from what they pay today. Takes the money already leaving their account for this problem, works out the year, and gives three prices with what each one leaves them, or checks a price you already have in mind, with the working shown so it can be argued with. Then puts the chosen price on the deal. Use when the user says "what should I charge", "pricing", "how much is this w…

requirements
Requirements. Turns what paying customers asked for into the build list. Captures each ask in their own words with the feature it becomes, merges the same feature across customers, and ranks the list by how much paid money is behind each line, so you build exactly what was paid for and nothing else. Asks from people who haven't paid wait on a separate list. Logs each customer confirming the list,…

whale-hunter
Whale Hunter. Finds the decision makers and pitches them. Looks up who signs the check, who owns the budget and who feels the pain at a company you want as a customer, using public business sources only, then writes a short pitch to the right person: what they pay today, the demo, and one small ask. Every email waits for your yes and goes out from your own account, with the legal footer and a pla…

Review before you install
A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
