Test it before you build it

$600 · 4 weeks · 25 prospects

For $600 and 4 weeks, prove creators already selling prompt products will pay for skill testing and license keys before the harness is built.

Riskiest assumption · Creators already earning from paid prompt products lose enough money to model-update breakage and unpaid resharing that they will pay an independent tool $149 a year now, rather than wait for agentskills.io or a model vendor to bundle testing and paid distribution.

1Focus group: who and where

A solo creator or consultant with a live Gumroad or personal-site storefront selling prompt packs or Claude templates at $20-200, who this quarter fielded refund requests after a model update broke their product or watched it get reshared for free

where to find 25 · Gumroad marketplace search for Claude and ChatGPT prompt packs, which surfaces 30+ active sellers with linked socials in an afternoon; r/PromptEngineering and r/ClaudeAI, where these sellers post and promote; creators on X and YouTube who publish Claude and Copilot skill tutorials and sell to their audience

2Sell first, build later

Founding creator package: version control for one SKILL.md folder, regression runs against three saved tasks on every model update, and license-key checkout wired into the creator's own storefront, live within 30 days of the fifth reservation

the ask · $149 for the first year, reserved with a $49 refundable deposit; the standalone manual regression report is $79

a real yes · A real yes is a $49 reservation charged or a $79 report paid; retweets, 'this is exactly what the ecosystem needs', and offers to promote it in exchange for free access are noes

3Small experiments

The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.

  1. 1. Prompt seller pain calls

    $100 · 10 days

    Pull 40 active sellers of Claude and ChatGPT prompt products from Gumroad search and their linked X profiles, DM or email each, and book 15 twenty-minute calls. Ask what happened to sales and support the last time a model update changed behavior, whether their files get reshared, and close with the $49 founding reservation.

    keep going if · 9 of 15 report a model update breaking a paid product or unpaid resharing costing them sales, and 5 of 15 pay the $49 reservation

  2. 2. Founding reservation page

    $150 · 10 days

    A one-page site: your methodology as a versioned, regression-tested, license-keyed Agent Skill sold from your own site, founding year $149, reserved with $49 refundable. Share it in r/PromptEngineering and r/ClaudeAI where rules allow, send it after every call, and ask two interviewed sellers to repost it to their audiences.

    keep going if · 8 reservations from 40 contacted sellers plus 200 page visitors

  3. 3. Paid manual regression report

    $350 · 14 days

    Sell a $79 standalone report: the founder hand-runs one seller's existing skill or prompt pack against three of the seller's saved tasks on Claude and Copilot, and delivers a pass-fail diff showing exactly where it breaks. Offer it on calls to sellers who balk at the reservation; deliver each within 4 days.

    keep going if · 5 sellers pay $79, and 3 of the 5 upgrade to the $149 founding year after seeing their report

4Collect a deposit up front

Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.

$49

per prospect, refundable

how · A refundable $49 reservation through a card checkout on the landing page, sent as a link at the end of each DM thread and call; these are creators who themselves sell through instant checkout links, so paying that way is native to them, and the $79 regression report is a second, invoiced way for skeptics to move money first set up: Stripe Invoicing

what it reserves · A slot in the 10-creator founding cohort, the $149 first-year price locked, and their top skill onboarded first with license keys live within 30 days of the fifth reservation

refund · Refunded in full on request any time before onboarding, or automatically if licensing is not live within 30 days of the fifth reservation

target · 8 paid commitments (a $49 reservation or a $79 report) from 40 contacted sellers within 28 days

Go: build it if

8 of 40 contacted sellers move money in 4 weeks, including at least 3 full $149 founding-year purchases

Kill: stop if

Fewer than 3 sellers pay anything after 40 DMs and 15 calls, or interviewed sellers consistently say model-update breakage and resharing cost them nothing worth paying to fix

outreach message

You sell prompt packs on Gumroad, and Agent Skills are where that business is heading. I'm building Skillcask: it versions your SKILL.md folder like code, regression-tests it against your saved tasks on every model update, and issues license keys so buyers can't just repost your files. Before writing production code I'm talking to 15 sellers already earning from prompts. Got 20 minutes this week? Either way, I'll hand-test one of your products against three tasks and send you the results.

Sell your expertise as a versioned, tested, licensed Agent Skill $49 refundable reservation locks the founding year at $149 with license keys included Reserve your founding creator slot

deposit terms

Your $49 reserves one of 10 founding creator slots and locks your first year at $149. Your skill gets versioning, regression tests against your own saved tasks, and license-key checkout on your site within 30 days of the fifth reservation. Cancel before onboarding, or if we miss that deadline, and the full $49 comes back within 5 business days.

The concept in full

What
Authoring and licensing infrastructure for experts who package their methodology as Agent Skills. It versions SKILL.md folders like code, runs regression tests against sample tasks on each model update, and issues license keys so a creator can sell a skill from their own site with install-time verification. In the first hour a user imports an existing skill folder, runs the test harness against three saved tasks, and generates a paid license link.
Grounded in (2025-2026 signals)
Agent Skills launched October 16, 2025 and became an open standard on December 18, 2025 (agentskills.io); by June 2026 about 40 products supported it, including Claude, OpenAI Codex, GitHub Copilot, VS Code, Cursor, Gemini CLI and Goose. The collection's data shows only 4 companies in the last 2 years mention 'agent builder' and 2 mention 'prosumer', so the tooling layer around skills is nearly empty.
What it rides
Rides 'Agent Skills: launched October 16, 2025, an open standard since December 18': once about 40 products support the format, a skill is a durable artifact worth versioning, testing and charging for, and the tooling around that artifact is unbuilt.
Why now
The standard went open on December 18, 2025 and reached roughly 40 supporting products by June 2026, so a skill written once now addresses every major assistant; the window is before a platform vendor bundles versioning and licensing into its own store.
Wedge: first customer and entry point
Creators and consultants who already publish paid prompts and templates and want to ship a skill their buyers install into Claude or Copilot; entry point is the test harness alone, which is useful before any selling happens.
Closest real companies, as the generator saw them
The Prompting Company helps products get discovered by AI agents, which is distribution for companies, not tooling for individual skill authors. Confident AI evals whole LLM applications for engineering teams. No company in the brief versions or licenses skills; closest matches are adjacent, so effectively none tracked on the core function.
Main risk
agentskills.io or a model vendor ships first-party skill testing and paid distribution, absorbing the layer before an independent tool gets adoption.
