Method and system for exposing virtual assistant services across multiple platforms

A system comprising;

• one or more hardware processors;
• one or more non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, causes performance of operations comprising:
• executing a query system comprising an execution engine and a plurality of wrapper services, the plurality of wrapper services includes (a) a first wrapper service for converting messages between a first protocol of a first virtual assistant platform and a target protocol and (b) a second wrapper service for converting messages between a second protocol of a second virtual assistant platform and the target protocol;
• receiving, by the query system, a specification for a skill, wherein the specification for the skill defines a state diagram including a set of nodes representing different states in a natural language interaction and edges for transitioning between nodes based on intents determined from natural language inputs;
• converting, by the first wrapper service, a request from the first virtual assistant platform to the target protocol, wherein the request invokes the skill;
• generating, by the execution engine based on the specification for the skill and the request converted to the target protocol, a response;
• converting, by the first wrapper service, the response to the first protocol of the first virtual assistant platform;
• and
• sending the response converted to the first protocol to the first virtual assistant platform.
