• Domain knowledge: package specialized knowledge into reusable instructions — from legal due diligence processes to data analysis pipelines.
• New capabilities: give agents new capabilities (for example, creating presentations, creating MCP servers, analyzing datasets).
• Repeatable workflows: turn multi-step tasks into sequential and verifiable workflows.
• Interoperability: use the same skill across different skill-compatible agent products.

Already supported in: OpenCode, Cursor, Amp, Letta, Goose, GitHub, VS Code, Claude Code, Claude
