You are building a structured data extraction system using Claude. The system extracts information from unstructured documents, validates the output using JavaScript Object Notation (JSON) schemas, and maintains high accuracy. It must handle edge cases gracefully and integrate with downstream systems.
Monitoring shows 12% of extractions fail Pydantic validation with specific errors like "expected float for quantity, got `2 to 3'". Retrying these requests without modification produces identical failures.
What's the most effective approach to recover from these validation failures?

• A. Send a follow-up request including the validation error, asking the model to correct its output.
• B. Pre-process source documents to standardize problematic formats before sending them for extraction.
• C. Implement a secondary pipeline using a larger model tier to reprocess documents that fail validation.
• D. Set temperature to 0 to eliminate output variability and ensure consistent formatting.

Production monitoring shows that follow-up queries like "summarize what we learned about market trends" consistently take 40+ seconds. Investigation reveals the coordinator spawns the synthesis subagent for each summarization request, passing 80K+ tokens of accumulated findings. The coordinator already has these findings in its context from orchestrating the research.
What's the most effective way to improve response time for these follow-up summaries?

• A. Have the coordinator handle straightforward summarization requests directly using its existing context, reserving subagent spawning for complex analysis.
• B. Enable prompt caching on the synthesis subagent to reduce the overhead of repeatedly transferring the same research findings.
• C. Spawn the synthesis subagent with reduced context and have it request specific findings from the coordinator on-demand.
• D. Pre-generate and cache summaries at multiple granularities whenever new findings accumulate.

After the web search and document analysis subagents complete their tasks, the coordinator needs to spawn the synthesis subagent to synthesize the findings. What is the correct approach for providing the synthesis subagent with the information it needs?

• A. Pass reference identifiers and configure the subagent with read access to a shared memory store where other subagents deposited their results
• B. Provide the subagent with tool definitions that allow it to request outputs from other subagents via callbacks
• C. Include the complete findings from both subagents directly in the synthesis subagent's prompt
• D. Spawn the subagent with only a brief task description, relying on automatic context inheritance from the coordinator

You are integrating Claude Code into your Continuous Integration/Continuous Deployment (CI/CD) pipeline. The system runs automated code reviews, generates test cases, and provides feedback on pull requests. You need to design prompts that provide actionable feedback and minimize false positives.
A developer uses Claude Code to refactor a function during a development session. Before committing, the developer asks the same Claude session to review the code for issues. Later, a separate automated CI review catches several bugs that the same-session review missed.
What best explains this discrepancy?

• A. The session's context window necessarily became full, leaving insufficient capacity for meaningful review.
• B. The CI review must have used a more specific prompt, while the developer's review request was too general.
• C. Claude retains the implementation context and prior decisions in the session, making it less likely to challenge assumptions underlying its own changes.
• D. The CI environment can access the full repository, while a local Claude Code session can access only the current file.

You are using Claude Code to accelerate software development. Your team uses it for code generation, refactoring, debugging, and documentation. You need to integrate it into your development workflow with custom slash commands, CLAUDE.md configurations, and understand when to use plan mode vs direct execution.
You're implementing a new payment processing module that must follow your project's established patterns for database transactions, error handling, and audit logging. You've identified three existing modules that exemplify these patterns: db_utils.py, error_handlers.py, and audit_logger.py. This is a one-off integration task - these patterns are well-documented in your team wiki and don't need additional project-level documentation. What's the most effective approach?

• A. Add documentation of each pattern to your CLAUDE.md file, establishing them as project conventions that Claude will apply automatically.
• B. Describe the patterns from the three modules in natural language in your prompt, explaining the transaction handling approach, error format, and logging conventions Claude should follow.
• C. Ask Claude to explore your codebase to find and understand the transaction, error handling, and logging patterns before generating the new module.
• D. Use @ references to include the three modules directly in your prompt, giving Claude concrete code examples of the patterns to follow.
