## 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.

## About xfiles

xfiles is a collection of file tools that run in the browser. The site lists 174 tools across PDF, image, file and audio categories, and states that files are processed on the user's device rather than uploaded. Examples include merging PDFs, splitting PDFs, compressing and resizing images, converting text to speech, and creating a ZIP archive from several files.

The PDF tools cover a wide range of tasks, from rotating, reordering and removing pages to adding page numbers, watermarks and passwords, redacting content, and inspecting a file's structure and metadata. The image tools include compression, resizing, cropping, format conversion, background removal, filters, favicon generation and GIF creation. The file tools include a ZIP extractor, hashing and checksum calculation, file encryption and a hex viewer.

The site is aimed at people who need quick file tasks without installing software or creating an account. Its stated benefits are that no account is needed and that no watermarks are added to output. Documents, photos and audio recordings can be handled in one place.
