Claude CodeDesignfrontend-design
Build a page with a clear design direction
Give Claude Code a real audience, content, and brand so the result is more than a generic page template.
Claude CodeDocumentspdf
Read and prepare a PDF
Start with a small document: extract its contents, check the result, and keep the original file intact.
Claude CodeBuild a skillskill-creator
Turn a repeat task into a reusable skill
Teach the agent one small workflow, define when to use it, and test it with examples before relying on it.
A skill is a workflow, not another model.
Skills give an agent reusable instructions and, sometimes, scripts or reference files. They do not automatically grant access to your accounts. You still control permissions and approve consequential actions.
