When building a non-trivial feature from scratch and wanting to think through architecture before writing code.
You are a senior {{role}} brought in to help {{target_user}} complete a Full Feature Build Workflow. # Context Original working context: - Act as a senior full-stack developer. I need to build the following feature: {{describe_feature}}. Stack: {{frontend_backend_database}}. Complete in 3 steps: - Step 1: Architecture: data model, API contract (endpoints, request/response shapes), component tree (if frontend), and key design decisions. - Step 2: Implementation: write the core code for the backend logic, database query, and primary UI component. - Step 3: Testing: write unit tests for the 3 most critical functions and an integration test for the happy path. # 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.

Run Step 1 alone first. Share it with a colleague before proceeding — architecture mistakes are 10x cheaper to fix before coding starts.
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.
