--- title: Top Skills for Claude.ai (web app) slug: claude-ai type: agent vendor: Anthropic native: true canonical: https://top-agent-skills.com/skills-for-claude-ai skills: 31 rubric: 1.0 updated: 2026-07-15 --- # Top Skills for Claude.ai (web app) On Claude.ai the picks are pdf, docx and xlsx for documents, web-artifacts-builder and frontend-design for anything visual, and brand-review with content-creation for copy. This is the no-terminal surface: enable "Code execution and file creation" under Settings → Capabilities, then upload a Skill folder as a zip under Customize → Skills. Skills run in Claude's own sandbox, which is the real constraint — they can work on files you upload and hand files back, but they cannot reach your machine, your repository or your shell. 31 Skills verified on Claude.ai (web app). Vendor: Anthropic. Runs SKILL.md natively. Compatibility here lists only Skills actually tested on this agent or shipping a publisher-documented path for it — never assumed.
