## About Humans to Know

Humans to Know is a web directory of reusable AI agent skills. A skill packages instructions, sometimes with scripts, references or templates, for a repeatable task such as reviewing code, planning research or writing a product brief. You can browse published skills, read their instructions and follow links to the original source.

Each skill is listed with the people and teams who publish it, and their profiles show how many skills they have shared. The site ranks humans by published skill count, which is a catalog measure rather than a measure of quality. Makers can publish a skill by sharing their instructions and source.

Rights stay with the original authors, and each source license sets how a skill can be used. Agents can read public skill pages through llms.txt or connect through MCP. Finding a skill does not install or run it, so users should test it on a small task first.
