US Patent 11461311 Bot extensibility infrastructure

The present disclosure relates generally to techniques for extending or customizing base skills (e.g., chatbots). According to certain embodiments, a bot extension infrastructure is provided to facilitate customization and/or extension of base skills, separately tracking different versions of the base skills and the extensions, applying an extension to different versions of a base skill, or applying different versions of extensions to a same base skill. The extensions to the base skills include JSON extensions indicating modifications to metadata of the base skills. A base skill (e.g., downloaded from a skills store) can be extended or customized by applying a JSON extension that describes the changes to be made to the metadata of the base skill.
