# Context Hub

> Manage the instructions and tools your agents use with version control and environment promotion in the LangSmith Context Hub.

The Context Hub gives your team version-controlled, environment-aware management of the instructions and tools your agents use in production. A *context* is a versioned bundle of agent instructions and tools, either a skill or a full agent, that you manage in LangSmith and promote to an environment so your agents can pull it.
