Installing Skills on Claude

Claude supports Agent Skills natively across all three products. Skills uploaded to claude.ai → Customize → Skills appear in both Claude Chat and Cowork — they share the same personal skill library. Skills bundled in a Cowork plugin (like handsonai) are Cowork-only — Claude Chat has no plugin install surface, so plugin-installed skills don’t cross over.

Claude.ai (web)

Upload a skill .zip under Settings > Capabilities > Upload skill. Requires Claude Pro, Max, Team, or Enterprise and Code execution turned on.

→ Use Skills in Claude (official Anthropic docs)

Claude Cowork

Open the Cowork tab in the Claude Desktop app, then go to Customize → Browse plugins → Personal and add a marketplace. Skills bundled in the plugin (including the framework-agent orchestrator) run in Cowork only — they’re not available in Claude Chat. If you also want the seven framework skills in Claude Chat, upload them via claude.ai → Customize → Skills (covered above) — skills uploaded that way appear in both Chat and Cowork.
