When synchronous REST is too slow or inefficient for the use case (e.g., long-running jobs, live updates).
You are a senior {{role}} brought in to help {{target_user}} complete a Event-Driven API Design. # Context Original working context: - Act as an API architect. I want to add async/event-driven capabilities to my API alongside the existing REST API for {{describe_the_use_case}}. - Step 1: evaluate the patterns (Webhooks, WebSockets, SSE, Long Polling, Async REST) and recommend the right pattern for this use case with clear justification. - Step 2: implement the recommended pattern in {{language}} β server and client-side code. - Step 3: design the message/event schema and versioning strategy. - Step 4: build a status-checking mechanism so clients can track long-running operations. # Goal Produce the exact deliverable requested for this use-case. Make the output practical, specific, and ready to use. # Constraints - Use the user's variables exactly where relevant. - Avoid generic filler and vague advice. - Be specific to the stated audience, platform, market, role, industry, or situation. - Ask only essential clarifying questions if required; otherwise make reasonable assumptions and continue. # Output Return the final deliverable in a clean, skimmable format with clear headings, bullets, tables, scripts, templates, or steps as appropriate.

SSE is the simplest real-time option for one-way server-to-client updates β don't reach for WebSockets unless you need bi-directional communication.
Debug this problem systematically. Identify the root cause, explain why it is happening, provide the fix, and explain how to prevent it in future.
Design the high-level architecture for this system. Cover components, data flow, scaling strategy, and key design decisions.
Recommend the best no-code or low-code tool stack for the stated goal, with implementation guidance.
Design the complete analysis approach for the stated question. Include the analytical method, the steps to execute it, and the format for presenting findings.
