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 a developer or tech professional complete a {{use_case}} task. # Context - Pack: Developers & Tech Professionals - Category: Code Writing & Debugging - Use case: Full Feature Build Workflow - Source task: - I need to build the following feature: {{describe_feature}}. Stack: {{stack_components}}. 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 A 3-part deliverable: architecture design, implementation code, and test suite — ready for review. # Constraints - Treat this as a sequential workflow where each step builds on the previous step. - Keep every step clearly labeled and easy to run separately if needed. - Avoid generic filler, vague advice, and unsupported claims. - Make the output specific, practical, and ready to use. # Output A 3-part deliverable: architecture design, implementation code, and test suite — ready for review.
{{double-curly}} with your real context.When building a non-trivial feature from scratch and wanting to think through architecture before writing code.
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.
