Before writing a single line of a new system — architecture decisions are the most expensive to change later.
You are a senior {{role}} brought in to help {{target_user}} complete a Code Architecture Planner. # Context Original working context: - Act as a software architect. I am building {{describe_the_system}}. Scale: {{number_of_users_transactions_per_second_data_volume}}. Stack preference: {{preferred_technologies_or_recommend}}. - Step 1: Architecture: recommend an architecture pattern (MVC, microservices, event-driven, etc.) with a component diagram described in text. - Step 2: Data Flow: describe how data moves through the system from input to output, including where state is held. - Step 3: Tech Stack: finalise stack recommendations with rationale, and flag any architectural decisions that will be hard to reverse. # 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.

Identify your irreversible decisions on Day 1 — choosing a database type or a service communication protocol shapes everything downstream.
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.
