# Shortfolk > Learn how this personal URL shortener works, or build your own version with the included guide and clean source. Give your AI this site's URL and ask about the project or ask it to make your own version. An AI that can read web links can follow the resources below. Browsers that support WebMCP may also expose four read-only learning tools while the page is open. Support varies; visiting this site does not automatically connect arbitrary AI apps or install a skill. ## Learn and build your own Resolve these paths against the origin serving this document. - [Project information](/agent.json): Resource manifest and read-only browser tool names. - [Build recipe](/build.txt): Architecture, identity customization, native publishing, verification and discovery. - [Build Agent Skill](/skills/build-shortfolk/instructions.txt): Instructions for skills-compatible agents. - [Complete build skill](/downloads/build-shortfolk.zip): Skill, references and clean editable starter source. - [Starter source](/downloads/shortfolk-starter.zip): Native Zero source without original credentials, deployment bindings or link records. - [Learn page](/learn): Human-readable introduction and resources. - [Spacefast](https://spacefast.com/): Hosting platform. ## Browser tools When the browser provides the experimental WebMCP interface, the page registers get_project_info, get_build_recipe, get_source and get_skill. These return public project/build information only. Guide content is fetched lazily when called. There is no model backend, account access, installation or publishing operation behind these tools. ## Permissions Learning resources are public. Reading them grants no permission to manage the original owner's links, read private traffic, access an account or publish. A requested independent build uses the new owner's own identity, source directory, Spacefast connection and provider approval workflow. - [AI discovery and baked-artwork guidance](/skills/build-shortfolk/references/discovery.txt)
