The ecosystem by tool type
Agent skills and MCP servers make up the overwhelming majority of the catalog - skills are the largest single category, with MCP servers close behind as the connective tissue that gives agents real-world tools. Marketplaces, which bundle and distribute the rest, are a smaller but structurally important slice.
Tools by build-journey phase
Mapped onto the seven phases of shipping a product, the catalog is heavily weighted toward the Build phase - the hands-on-keyboard work of writing the product - followed by Ship and Idea. The thinner phases (Validate, Launch, Grow) mark where the agent-tooling ecosystem is still maturing - and where a new tool faces the least competition.
The biggest categories
By subject, developer- and AI-tooling categories dominate - unsurprising for tools built to help engineers build with agents. The long tail (finance, data, infrastructure) shows the ecosystem spreading well beyond pure coding.

How this report is compiled
Every figure is a live count over the Skillselion catalog - agent skills, MCP servers and marketplaces ingested from the skills.sh registry and GitHub, each screened against one quality bar. Install counts come from the registry; star counts from GitHub. The numbers regenerate daily, so this page always reflects the current state of the ecosystem rather than a frozen snapshot.
