[Data contracts](https://ask.atlan.com/hc/en-us/articles/9281528742799) are agreements between data producers and consumers, that specify requirements for generating and using high-quality, reliable data.

- You can [manage data contracts](https://docs.atlan.com/llms/governance/contracts/manage-via-cli/llms.txt) using Atlan's [command-line interface (CLI)](https://docs.atlan.com/llms/platform/python/set-up-sdk/llms.txt).
- You may also want to refer to the [data contracts specification](https://docs.atlan.com/llms/platform/python/data-contract-spec/llms.txt), to understand how data contracts are defined.
