Skillry sells Agent Skills: folders of instructions, templates and scripts that an AI agent loads when a task needs them. Anthropic introduced the format for Claude on 16 October 2025 and published it as an open standard on 18 December 2025. Skillry's Skills are for coding agents, AI programs such as Claude Code, Codex and Cursor that read and write files on the user's own computer. Each Skill makes one kind of visual work in one designed style: a landing page, a testimonial section, a slide deck, a set of article illustrations or a short launch video. Each Skill page shows that output before the buyer installs it. On 15 October 2026 the site's sitemap listed 404 Skills.

The founder is shown on TrustMRR as Yihui, from China, with a team of one and a linked X account of 62,545 followers. The founding date there is 8 August 2026, and the site's first blog post is dated 30 August. Almost nothing sold until 28 September 2026. TrustMRR, a site that reads a startup's revenue directly from its payment provider, shows US$7,715 from 28 September to 15 October. On 15 October it showed US$7,747 in the last 30 days, US$7,855 in total, 264 active subscriptions and MRR (monthly recurring revenue: what the active subscriptions bring in each month) of US$2,600.

The revenue numbers are grade A, read by TrustMRR from Skillry's own Stripe account. They cover only 18 days of real sales. Daily revenue stayed near US$430 a day, with no single large spike, but it did not grow. Only about one third of the 30-day revenue is MRR; the rest came from payments that do not repeat each month or from subscriptions that ended. The page also shows what the AI companies give away for free, and what happened to earlier companies that sold a curated layer on top of someone else's platform.

Skillry: US$7.7K revenue in the last 30 days, October 2026. Paid library of Agent Skills for AI coding agents, China, solo founder, evidence grade A.

03

Why it worked

Four causes, in the order they mattered. Each one is a reusable lesson.

01

Previews of real output

Each Skill page opens with a gallery of what the Skill makes, so a buyer chooses a style the way one chooses a template. The founder's TrustMRR text names this as the value: preview the real output before installing. The company describes the method: each Skill "starts as a finished piece of work we design ourselves", and then it writes "the instructions, templates and scripts that let your agent make it again".

02

One plan for a catalog that grows every day

Premium covers every paid Skill and every new one, and on average about six Skills a day were added since the founding date (calculated). The US$169 Founding Lifetime price "increases as the library grows", which gives a reason to buy early.

03

A page for each Skill, task, role and agent

The sitemap has 1,312 English pages, among them the 404 Skill pages and install guides for 32 agents, and the same pages in eight more languages, 11,808 addresses in total. Free Skills need only an account. The founder lists X, Threads, YouTube, search and content marketing as channels; no source shows which of them brought the buyers.

04

No model costs for the seller

Most Skills run on the buyer's own agent and its model ("Generates with Host Agent LLM"). Image and video Skills call outside models such as FAL "with your own API key, and that provider bills you per use". Skillry sells files, so a sale adds no model cost for it.

How it was built

These details come from the founder's TrustMRR profile and the company's own pages. They are grade C. [1, 4, 3, 8, 9, 5, 7]

  • Frontend in React, TypeScript and Tailwind CSS; backend on Cloudflare with SQLite and Node.js; payments through Stripe. This is the founder's tech-stack list on TrustMRR.
  • A Skill is a folder: a SKILL.md file with the instructions, plus scripts, references, installation instructions, previews and other supporting files. The terms say the downloaded package is the product.
  • Installation by a copied install prompt, a ZIP download, or the Skillry command-line tool, which authorizes through the browser and "keeps a revocable credential in your system keychain".
  • The Article Illustration Set, a paid image Skill, needs a FAL account and Node.js 20 or newer, and generates with GPT Image from OpenAI.
  • Web Skills ship as source code: a component file and a runnable usage example, with colors, type and corner radius as tokens to edit in one place, and images stored locally.
  • Parts of the catalog include or derive from MIT-licensed open-source work: libraries such as React, Tailwind CSS, Ant Design, Shadcnblocks and ReUI, and work by individual developers and small studios, all named on the Third-Party Notices page.
  • Pages in nine languages: English, Simplified and Traditional Chinese, Japanese, Korean, Spanish, Brazilian Portuguese, German and French.

The dead that came before

Four companies in the Loot Drop database sold a curated or better-designed layer on top of a platform, and lost when the platform or free tools did the same job. The values below are from that database and are not independently verified.

Died 2011 to 2014Burned US$3M

Iddiction

The promise

A curated app store to help people find good apps among millions.

Why it died

Apple and Google improved discovery inside their own stores, and a separate curated store lost its reason to exist.

Died 2009 to 2015Burned US$5M

Readability

The promise

Clutter-free reading of any web article.

Why it died

Browsers added free reader modes and free extensions did the same. Few readers paid.

Died 2006 to 2014Burned US$9M

Xmarks

The promise

Sync your bookmarks and tabs across browsers.

Why it died

Chrome, Firefox and Safari built the same sync into the browser, for free.

Died 2009 to 2012Burned US$20K

Jobspice

The promise

Good-looking resumes for job seekers who cannot design.

Why it died

One narrow product. LinkedIn and free tools gave job seekers the same result without paying.

What changed

Each of the four sold something that a larger platform, or a free tool, later gave away: a better way to find apps, to read articles, to sync bookmarks or to make a document look designed. Skillry has the same exposure. Anthropic, which created the Skill format, ships its own Skills for documents and slides, runs a directory of partner-built Skills, and lets anyone host a plugin marketplace. Free Skills such as Anthropic's frontend-design are easy to install, and Skillry's own guide lists them.

Two things differ. First, Skillry does not sell access to a platform but finished visual styles, hundreds of them, each shown with real output, and the platform makers do not make styles in that number. Second, the format is an open standard, and Skillry has install guides for 32 agents, so a change at one AI company does not close the store. What 18 days of sales cannot show is whether buyers keep paying after the first month.

05

Can one person copy it now?

The method, yes. The speed and the audience, not easily.

A Skill costs little to make: a SKILL.md file, templates and scripts. What is hard to copy is a catalog of 404 styled Skills built in 68 days, real previews for each, and a founder with 62,545 followers on X, although no source shows that the followers brought the buyers.

Where it is still open: Skills for work where design taste matters and the model makers do not compete: brand-specific styles, industry document formats, video templates, and Skills for the newer agents that appear after Claude Code and Codex.

  1. 1Pick one kind of output that agents make badly, for example slides or landing pages, and design finished examples first.
  2. 2Turn each example into a Skill: instructions, templates and scripts that let the agent make it again.
  3. 3Show the real output on each Skill page, and give some Skills away to anyone with an account.
  4. 4Sell one plan for the whole catalog, and add Skills often so that the plan keeps growing.

What to watch

The risks are the mirror image of the causes above.

Only 18 days of sales

Almost all revenue came between 28 September and 15 October 2026. Daily revenue held at about US$430 but did not rise: the second week was 12.3% below the first. The first monthly subscriptions renew from late October, and only then will churn, the share of buyers who stop paying, be visible.

Most of the money is not monthly recurring

MRR is US$2,600, about a third of the 30-day revenue. The rest came from yearly plans paid in advance, US$169 lifetime licenses, US$4.99 single Skills, or subscriptions that ended; none of it comes back next month, and TrustMRR does not show the split. A lifetime buyer pays once and keeps access to every future Skill.

The AI makers run their own directories

Anthropic introduced Agent Skills on 16 October 2025, with its own Skills for Excel, PowerPoint, Word and PDF files. On 18 December 2025 it added "a directory featuring partner-built skills" and published the format as an open standard. Since 9 October 2025 anyone can host a Claude Code plugin marketplace, "curated collections where other developers can discover and install plugins". A paid catalog competes with free directories, one of them run by the platform owner.

Free Skills exist for the same jobs

Skillry's own guide describes Anthropic's frontend-design Skill as "Official" and "Free", "a single SKILL.md published in Anthropic's public skills repository", and reviews UI UX Pro Max, Impeccable and Taste skill next to it. Skillry's answer is finished templates instead of design rules, but a buyer can compare them at no cost.

Parts of the catalog derive from open-source work

The Third-Party Notices say that "portions of the catalog include or are derived from" MIT-licensed software by 21 named copyright holders, from large libraries to individual developers. The MIT license allows this with credit. The home page says "Every Skill is designed, written and tested in-house", and the three Skill pages read for this story credit no outside author, so a buyer cannot see how much of a Skill is derived.

Dependence on the agents' formats

The terms say it directly: "AI agents, models, and third-party tools can change independently of us." Skills depend on how Claude Code, Codex, Cursor and the others load SKILL.md files, and image and video Skills depend on outside models billed to the buyer. Install guides for 32 agents spread this risk, and they also multiply the testing work for a team of one.

A very young business with no named company

The founder appears on TrustMRR only as Yihui, and the terms and privacy policy name no company, only "Skillry and its operators" and a support address. Payments are non-refundable, and the terms say a lifetime license "is not a promise that the Services will operate forever". The business was 68 days old at the headline figure.
