📊 Full opportunity report: The Skills Marketplace Nobody Is Building Yet on ThorstenMeyerAI.com — validation score, market gap, and execution plan.
TL;DR
While an open standard and reference implementations for AI skills exist, there is no dedicated marketplace akin to an app store. This gap hampers discovery, monetization, and security, leaving a key infrastructure layer unbuilt.
Despite the existence of an open standard, reference implementations, and community directories for AI skills, no dedicated marketplace or app store has been built to host, monetize, or vet these skills, leaving a critical infrastructure gap in the evolving AI ecosystem.
As of May 2026, over 140 free AI agent skills are available on community platforms, with official skills published by companies like Anthropic, Microsoft, Google, and Vercel. The open standard for skills, defined at agentskills.io in December 2025, has been adopted by major players and integrated into tools like OpenAI’s Codex CLI and Anthropic’s Claude. However, there is no centralized marketplace akin to an app store where these skills can be discovered, verified, or monetized.
The current ecosystem features directories such as SkillsMP, ClaudeWorld, and GitHub repositories, but these lack formal vetting, security audits, or revenue sharing mechanisms. Skills are free, and the discovery process relies on community reputation, GitHub stars, and word of mouth. There is no system for paid skills or verified author contributions, and cross-surface portability remains limited, with skills not transferable across different AI platforms.
This gap is significant because it leaves a key layer of AI infrastructure unbuilt—one that could enable organizations to package, share, and monetize procedural knowledge and organizational expertise effectively. Without a dedicated marketplace, the ecosystem remains fragmented, and the full potential of portable, durable AI artifacts is unrealized.
The skills marketplace.
The directory exists. The marketplace doesn’t. Here’s the gap — and who closes it.
There are 140+ free Agent Skills on community marketplaces today. 17 official Anthropic skills under Apache 2.0. A published open standard at agentskills.io that OpenAI’s Codex CLI adopted. Microsoft, Google, Vercel publishing skill collections. And no skills equivalent of the App Store. No revenue share. No vetted-author verification. No security audit pipeline. No paid skills at all.
Folder. Frontmatter. Instructions.
A skill is a directory containing a SKILL.md file with YAML frontmatter and Markdown instructions, plus optional scripts and templates. Progressive disclosure: the agent loads only metadata into context until the skill becomes relevant. The format is simple. The implication is significant.

Five layers, in roughly the order they emerged. The first five are real and growing. The last five are the capture gaps — each is a real product, each is uncaptured, and any company that solves four of five wins the layer.

The platform owner’s incentives do not align with the developer’s.
Same structural problem that produced the App Store / Play Store / Steam separation in mobile and gaming. The platform owner extracts rent at the marketplace layer; the developer wants to publish once and distribute everywhere. The two only align if a third party owns the marketplace.
Skills as a platform retention feature.
- Cross-surface friction is a soft retention mechanism, not a bug
- Partner directory is curated to drive distribution into their stack
- Revenue share competes with the lab’s own enterprise sales motion
- Verified-publisher status is awkward when the auditor is also the model vendor
- Skills tied to one model = same problem the standard was built to solve
Three fronts the labs cannot credibly compete on.
- Cross-surface neutrality — “publish once, run on any model”
- Verified-publisher status as a paid security service
- 70/30 revenue share creates incentives for vertical specialists
- Trust calculation is cleaner: auditor ≠ model vendor
- Wins by being the only neutral broker between labs and enterprise

Write the skills now. Capture when the marketplace ships.
The capture mechanism does not yet exist. Skills you write today have no way to charge for themselves. This is a feature, not a bug, for the next 12 months. Write skills, accumulate authorship reputation, build a portfolio that becomes legible the moment a marketplace with revenue share goes live.
The directory exists. The marketplace doesn’t. Whoever builds it captures the most defensible position in the post-model AI stack.
Four assignments. By role.
Start writing skills now.
The marketplace doesn’t exist yet but the reputation system runs on what you publish in 2026. The early-mover advantage when the marketplace ships is real. GitHub stars compound into discoverable authorship.
The window is open. Funding is favorable through Q3.
The standard is set, the demand is forming, the labs won’t build it themselves, and the second-mover penalty in marketplaces is severe. The “App Store of agents” thesis is investable today.
Demand a skill governance roadmap.
If your AI vendor’s answer is “we trust Anthropic to vet skills,” the answer is incomplete. Demand SIEM integration, audit logging, enterprise approval workflows. Current admin controls are a starting line.
The position is winnable in 2026 H2.
Natural fits: GitHub, Cursor, Replit. If you build developer tooling but aren’t one of those, you have 12 months to figure out whether your product becomes a skills publishing channel — or watches the value flow past it.
Why a Skills Marketplace Is Critical for AI Ecosystem Growth
The absence of a dedicated skills marketplace limits discovery, security, and monetization opportunities for AI developers and organizations. Building such a platform would enable better vetting, standardized distribution, and potential revenue streams, accelerating innovation and adoption of AI skills as a core infrastructure layer. This gap also represents a strategic vulnerability for larger companies that may fall behind in establishing a defensible position in the post-model-commoditization era, where skills become the primary unit of value.
The Evolution and Current State of AI Skills Infrastructure
The concept of AI skills emerged rapidly in late 2025, with the open standard at agentskills.io setting the foundation. Major companies like Anthropic, OpenAI, Microsoft, and Google have developed reference implementations and integrated skills into their products. Community directories and GitHub repositories host a wide array of free skills, but these are discovery-only and lack monetization, vetting, or security mechanisms. The ecosystem is in a nascent stage, with the standard established but the marketplace missing, creating a critical gap that could determine future industry leadership.
“The marketplace layer does not exist yet, despite the standard and reference implementations. This is the biggest missing piece in the AI skills ecosystem.”
— Thorsten Meyer
Unclear Timeline and Industry Adoption of a Skills Marketplace
It is not yet clear when a dedicated skills marketplace will be built or adopted at scale. Major companies may develop their own solutions, but a universal, open marketplace has yet to emerge, and industry consensus is still forming. The timeline for such a platform’s development and its potential features remains uncertain.
Next Steps Toward Building a Standardized Skills Marketplace
Industry stakeholders are likely to focus on establishing a marketplace platform that supports discovery, vetting, security, and monetization. Companies may collaborate or compete to develop the first scalable, open marketplace, with the window for early leadership estimated at 9 to 18 months. Regulatory, security, and standardization challenges will influence this process.
