Agents are increasingly capable, but often don't have the context they need to do real work reliably. Skills solve this by giving agents access to procedural knowledge and company-, team-, and user-specific context they can load on demand. Agents with access to a set of skills can extend their capabilities based on the task they're working on. **For skill authors**: Build capabilities once and deploy them across multiple agent products. **For compatible agents**: Support for skills lets end users give agents new capabilities out of the box. **For teams and enterprises**: Capture organizational knowledge in portable, version-controlled packages. ## What can Agent Skills enable? * **Domain expertise**: Package specialized knowledge into reusable instructions, from legal review processes to data analysis pipelines. * **New capabilities**: Give agents new capabilities (e.g. creating presentations, building MCP servers, analyzing datasets). * **Repeatable workflows**: Turn multi-step tasks into consistent and auditable workflows. * **Interoperability**: Reuse the same skill across different skills-compatible agent products. ## Adoption Claude Skills are supported by leading AI development tools.

## Open development The Claude Skills format was originally developed by [Anthropic](https://www.anthropic.com/), released as an open standard, and has been adopted by a growing number of agent products. The standard is open to contributions from the broader ecosystem.
