  • BETTER: “Show me how the login form manages loading states and error messages during authentication.”
  • GOOD: “Find the responsive navigation component.”

  • GOOD: “Find components that handle form validation.”
  • BETTER: “Show me how we handle form‑validation errors in the user‑registration flow, including error‑messaging and accessibility features.”
  • GOOD: “How does the dashboard component work?”
  • BETTER: “Walk me through the dashboard component’s state management, API calls, and how it handles loading and error states.”

​
Backend Engineer

  • System Architecture Intelligence: Understand service dependencies, API contracts, and data flow across microservices and databases.
  • Database and Query Insights: Find database schemas, query patterns, and optimization opportunities across your data layer.
  • API Discovery and Tracing: Locate endpoints, understand request/response flows, and trace business logic through multiple services.
  • Production Issue Correlation: Connect error logs, user sessions, and performance traces to identify root causes in distributed systems.
  • GOOD: “Find the user authentication service.”
  • BETTER: “Show me the complete user‑authentication flow from API request through JWT validation, database lookup, and response generation.”
  • GOOD: “Find the payment processing code.”
  • BETTER: “Show me the payment‑processing implementation related to errors or performance issues users have experienced during checkout.”
  • GOOD: “Find database queries for orders.”
  • BETTER: “Trace how order data flows from creation through payment processing, inventory updates, and fulfillment, including all database interactions.”
  • GOOD: “Show me the notification service.”
  • BETTER: “How does the notification service integrate with the user service and email provider? Show me the API contracts, error handling, and retry logic.”

​
Support

  • Instant Issue Diagnosis: Quickly correlate user descriptions with real system behavior.
  • Cross‑System Problem Solving: Connect user reports to code implementations, recent changes, and related historical issues.
  • Accurate Technical Translation: Bridge the gap between user language (“the button doesn’t work”) and technical reality (API errors, validation failures).
  • Intelligent Escalation: Provide engineering with precise context, relevant code sections, and reproduction steps.
  • GOOD: “Find issues with login problems.”
  • BETTER: “A user says they can’t log in and keep getting an error message. Show me what might be causing login failures and similar recent reports.”
  • GOOD: “Show me payment processing code.”
  • BETTER: “Multiple users report their credit‑card payments are being declined. What could cause this and how do we fix it?”
  • GOOD: “Why is the checkout page slow?”
  • BETTER: “Users complain about slow checkout. Show me causes of delay and any temporary work‑arounds I can offer.”
  • GOOD: “Find email‑delivery issues.”
  • BETTER: “Since yesterday, users haven’t received password‑reset emails. Show me the email system, recent changes, and similar past issues.”

​
Data Analyst

  • Data Schema Discovery: Understand database structures, relationships, and data models across your entire system.
  • Business Logic Analysis: Trace how business rules are implemented in code and how they affect data quality and meaning.
  • Data Pipeline Understanding: Map data flows from collection through transformation to storage and reporting.
  • Data Quality Insights: Identify validation rules, constraints, and data processing logic that impact data integrity.
  • GOOD: “Show me the user table schema.”
  • BETTER: “Trace how user data flows from registration through profile updates to account deletion, including all transformations and validations.”
  • GOOD: “Find revenue calculation code.”
  • BETTER: “Show me how revenue metrics are calculated in the code, including any business rules, discounts, refunds, and how this data is stored and aggregated.”
  • GOOD: “Show me data validation.”
  • BETTER: “What validation rules and data‑quality checks are implemented for customer data, and how do they ensure data consistency across the system?”
  • GOOD: “Find database connections.”
  • BETTER: “Show me all the places where user‑behavior data is collected, how it’s processed, and where it’s ultimately stored or exported.”

​
QA Engineer

  • Comprehensive Test‑Coverage Analysis: Identify critical code paths, branches, and integration points that demand testing.
  • Edge‑Case Discovery: Surface boundary conditions, unusual workflows, and error‑handling scenarios often missed by manual reviews.
  • Integration‑Testing Insights: Map service dependencies, API contracts, and data flows to craft effective integration tests.
  • Business‑Logic Understanding: Reveal complex validation rules so you can create meaningful, real‑world test cases.
  • GOOD: “Show me the login function.”
  • BETTER: “Show me the complete user‑authentication workflow—including login, session management, password reset, and account‑lockout scenarios.”
  • GOOD: “Find form‑validation code.”
  • BETTER: “Show me user‑registration validation covering all rules, error conditions, and edge cases I should test.”
  • GOOD: “Show me API endpoints.”
  • BETTER: “Map the payment‑processing flow, including all service interactions, external API calls, and failure scenarios to test.”
  • GOOD: “Find calculation functions.”
  • BETTER: “Show me how shipping costs are calculated, including discounts and international‑shipping edge cases.”

Business Analyst

  • Access Living Documentation & Architecture Maps: Generate current-state maps of services, data models, APIs, and dependencies from the code and runtime behavior.
  • Connect Business Rules to Code: Trace policies, pricing rules, SLAs, and workflows directly to the functions, services, and jobs that implement them.
