26.5 Interview Mode

Overview of Interview Mode

Interview Mode is an interactive feature in Claude Code that improves requirement understanding and solution quality by proactively asking users questions to clarify requirements and optimize solutions. This interactive approach transforms one-way requirement transmission into a collaborative dialogue, ensuring that AI outputs accurately reflect user intentions.

The interview pattern recognizes that requirements are often incomplete, ambiguous, or tacit when first expressed. Rather than proceeding with incomplete information and producing suboptimal results, Interview Mode engages users in structured conversation to extract and clarify requirements before work begins.

Interview Mode Workflow

1. Requirement Clarification

The system proactively asks questions covering various requirement dimensions.

Functional requirements questions explore what the system should do, what features users need, and what outputs or behaviors are expected. These questions help identify both stated and unstated requirements.

Technical requirements questions address technology preferences, framework choices, language requirements, and integration needs. Technical clarification ensures solutions align with existing systems and team capabilities.

Integration requirements questions examine how the solution should interact with other systems, data sources, or processes. Understanding integration needs prevents solutions that work in isolation but fail when connected to broader systems.

Performance requirement questions establish expectations for response time, throughput, resource usage, and scalability. Clear performance requirements prevent solutions that functionally work but perform poorly under load.

2. Solution Optimization

Based on user responses, the system optimizes its approach across multiple dimensions.

Architecture design optimization selects appropriate architectural patterns, component relationships, and data flows based on clarified requirements. The optimization considers scalability, maintainability, and performance requirements.

Technology selection optimization chooses appropriate languages, frameworks, libraries, and tools based on user preferences and project requirements. Selection balances user preferences with technical considerations.

Implementation strategy optimization determines how to structure code, which patterns to apply, and how to organize work based on requirements and constraints. Strategy optimization creates implementable plans.

Testing plan optimization determines what tests are needed, how to structure test coverage, and what validation criteria to apply. Testing plans are tailored to project risk profiles and quality requirements.

3. Implementation Execution

After optimization, work proceeds according to the refined plan.

Code generation produces implementation code following architectural decisions and technical requirements. Code generation is informed by the clarified requirements and optimization decisions.

Test generation creates appropriate test suites based on requirements and risk assessment. Tests validate that implementations meet stated requirements.

Documentation generation produces documentation reflecting the final implementation and user decisions. Documentation serves both current users and future maintainers.

Deployment configuration creates deployment configurations aligned with requirements and environment constraints. Configurations support smooth transition from development to production.

The AskUserQuestion Tool

1. Question Mechanism

The AskUserQuestion tool enables structured interaction with users during requirement gathering.

Clear question presentation ensures questions are unambiguous and focused, helping users provide relevant answers efficiently. Questions are worded to elicit specific, actionable information.

Multiple option support enables questions with predefined options, making it easy for users to provide responses. Options can include defaults, reducing the burden on users who are satisfied with standard choices.

Default value setting provides sensible defaults when users don't specify preferences, enabling progress even when users don't engage deeply with every question. Defaults are chosen based on common patterns and best practices.

Validation mechanism checks user responses for completeness and consistency, prompting for additional information when needed. Validation prevents incomplete requirement sets from proceeding to implementation.

2. Response Processing

Processing user responses transforms raw input into actionable requirement specifications.

Response parsing extracts structured information from user answers, converting natural language responses into formats suitable for downstream processing.

Validation checking verifies that responses satisfy question requirements, identifying missing or inconsistent information that needs follow-up.

Context updating maintains the current state of requirements, adding new information while ensuring consistency with previously gathered requirements.

Subsequent decision-making determines what questions to ask next based on responses received, creating a dynamic, adaptive interview flow.

Specification-Based Development

1. Defining Development Specifications

Development specifications establish standards and patterns that guide implementation.

Code specification defines coding standards including naming conventions, formatting rules, architectural patterns, and style guidelines. Code specifications ensure consistency and quality across implementations.

Architecture specification establishes architectural patterns, component relationships, data flows, and integration approaches. Architecture specifications provide structural guidance for implementations.

Testing specification defines testing requirements including coverage targets, testing approaches, and quality gates. Testing specifications ensure adequate validation of implementations.

Deployment specification establishes deployment patterns, configuration requirements, and operational procedures. Deployment specifications ensure smooth transition to production environments.

2. Applying Specifications

Specifications are applied consistently throughout the development process.

Code generation follows specifications, producing code that meets defined standards and patterns. Generated code is consistent with project conventions and quality requirements.

Testing covers specification requirements, ensuring implementations are validated against stated requirements. Tests are structured to verify specification compliance.

Documentation conforms to specifications, producing documents that meet project documentation standards. Documentation is consistent in format and content.

Deployment executes according to specifications, following established procedures and configurations. Deployment processes are reliable and repeatable.

Use Cases

1. Complex Requirement Analysis

Interview Mode is particularly valuable when requirements are unclear or complex.

When requirements are initially vague or incomplete, Interview Mode's structured questioning helps surface and clarify requirements systematically.

When multiple solution approaches exist and trade-offs need to be evaluated, Interview Mode can present alternatives and gather user preferences.

When important decisions require user input, Interview Mode ensures users are engaged at critical decision points rather than having AI make assumptions.

When multiple stakeholders with different perspectives need to be considered, Interview Mode can probe for diverse viewpoints and reconcile conflicts.

2. Architecture Design

For system architecture decisions, Interview Mode gathers the information needed for sound design.

During system architecture design, Interview Mode helps establish requirements that shape architectural decisions.

When technology stack selection requires evaluation of alternatives, Interview Mode gathers preferences and constraints that inform selection.

During integration方案 design, Interview Mode clarifies integration requirements and constraints.

When performance optimization strategies need evaluation, Interview Mode establishes performance targets and priorities.

3. Project Planning

For project planning activities, Interview Mode supports structured requirement gathering.

During project plan development, Interview Mode helps establish scope, timeline, and resource requirements.

When resource allocation decisions need to be made, Interview Mode gathers information about priorities and constraints.

During risk assessment, Interview Mode helps identify potential risks and mitigation strategies.

When timeline decisions require balancing scope and resources, Interview Mode gathers information to inform these trade-offs.

Summary

Interview Mode improves requirement understanding accuracy and solution quality through interactive questioning. The capabilities covered in this chapter, including requirement clarification, solution optimization, the AskUserQuestion tool, and specification-based development, provide a comprehensive approach to collaborative requirement gathering that ensures AI outputs align with user intentions.

By engaging users in structured dialogue, Interview Mode transforms the relationship between developers (including AI developers) and users, creating solutions that truly meet needs rather than assumed requirements.
