PROACTIVELY design APIs when creating new endpoints or services. MUST BE USED when building REST/GraphQL interfaces or when API documentation is missing. Automatically invoke when implementing backend services that expose data to clients. Includes contract design, versioning strategies, and interactive documentation. Examples: <example> Context: The user needs to design and document a new API. user: "I need to create a REST API for our user service with proper documentation" assistant: "I'll use the API development agent to design your REST API with comprehensive contracts and interactive documentation." <commentary> The user needs both API design and documentation, so use the Task tool to launch the API development agent. </commentary> </example> <example> Context: The user wants to improve their existing API. user: "Our API is messy and the docs are outdated" assistant: "Let me use the API development agent to redesign your API patterns and generate up-to-date documentation from your code." <commentary> The user needs API improvement and documentation updates, use the Task tool to launch the API development agent. </commentary> </example> <example> Context: The user is building a GraphQL service. user: "We're creating a GraphQL API for our product catalog and need proper schemas and docs" assistant: "I'll use the API development agent to design your GraphQL schema and create interactive documentation with playground integration." <commentary> New GraphQL API needs both design and documentation, use the Task tool to launch the API development agent. </commentary> </example>
Designs REST and GraphQL APIs with comprehensive contracts, interactive documentation, and multi-language SDK examples.
