About Claude.ai (web app)
Claude.ai is Anthropic's web app — the consumer and team-facing Claude — and it has supported SKILL.md natively since late 2025 across Pro, Max, Team and Enterprise tiers. Skills here run in a sandboxed cloud environment: they can read files you upload, write artifacts, and invoke certain tools, but they do not have local filesystem or shell access.
The install model is upload-based. From Settings → Features → Skills you upload a Skill folder as a ZIP. The Skill is then available across all your Claude.ai conversations. Team and Enterprise admins can publish Skills to their workspace so everyone gets them automatically. Most Anthropic document Skills (docx, pdf, pptx, xlsx) work identically on Claude.ai and Claude Code — the file in/file out workflow translates cleanly.
Claude.ai is the right Skill target for non-engineering users — marketing teams, ops, legal, finance — and for workflows where the agent works on uploaded artifacts rather than a live codebase. Skill compatibility is narrower than Claude Code by design; Skills here are ranked partly by how well they handle the upload/download flow.

FAQ
Frequently asked
How do I install a Skill on Claude.ai?
Settings → Features → Skills. Upload the Skill folder as a ZIP. The Skill becomes available in all your Claude.ai conversations.
Which tiers support Skills?
Pro, Max, Team and Enterprise. The Free tier does not. Team and Enterprise admins can publish workspace-wide Skills.
Can Claude.ai Skills run shell commands?
No — Claude.ai runs Skills in a sandboxed cloud environment. Skills that need shell or local filesystem access should target Claude Code instead.
Do document Skills work the same on Claude.ai and Claude Code?
Yes — the docx, pdf, pptx and xlsx Skills produce identical files because the underlying scripts run in the same sandboxed Python environment.
Can I share Skills with my team?
Team and Enterprise admins can publish Skills to the workspace; every member then has access without individual installs.
