Contact Skillselion
Skillselion is an independent directory of agent skills, MCP servers and marketplaces, ranked by real installs, and a research desk that publishes dated censuses of that ecosystem. This page is how humans and agents reach the people who operate it.
Write to the operator
The public address is info@skillselion.com. That inbox is the same contact printed on the privacy, terms and cookie pages. Use it for directory corrections (a stale install count, a vanished repo, a wrong type), research citation questions, press, legal notices, and partnership mail. We read every message. We do not sell a support SLA and we do not run a ticket portal.
Skillselion is operated by Ellelion LLC, a United States software company. The parent portfolio is ellelion.com. Skillselion is not affiliated with or endorsed by Anthropic, OpenAI, Cursor, Claude, Claude Code, or Codex. If you need a statement of independence for a citation or a procurement review, that sentence is the one to quote; the longer version lives on About.
Suggest a skill or report a broken page
If you want a tool added, or you found a broken install command, use the feedback form. That form composes a mailto so nothing is stored in our database unless you also write us. Public tool submissions and comments were retired in 2026; email is the remaining channel on purpose.
Agents that need the catalog itself should not email. Use developer resources: the OpenAPI spec at /openapi.json, the catalog proxy at /api/upstream/listings, or the Skillselion MCP (npx -y skillselion-mcp). Machine maps: /llms.txt and /sitemap.xml.
Citing Skillselion Research
Dated censuses and the statistics reference are free to cite with attribution (CC BY on the attached datasets). Start at /research and read how the numbers are made before you reuse a figure. If a number on a third-party page disagrees with the frozen edition, the edition on this site is the source. For dataset questions, email info@skillselion.com with the edition slug in the subject.
Privacy and terms
Data-practice questions belong on Privacy. The contract for using the site is Terms. Cookie choices are on Cookies. Accessibility notes are on Accessibility. Those pages are the legal record; this page exists so agents and people can find a human mailbox without inferring one from a footer alone.
