NO.111 You are building a customer support resolution agent using the Claude Agent SDK. The agent handles high- ambiguity requests like returns, billing disputes, and account issues. It has access to your backend systems through custom Model Context Protocol (MCP) tools ( get_customer , lookup_order , process_refund , escalate_to_human ). Your target is 80%+ first-contact resolution while knowing when to escalate.
The agent verifies customer identity through a multi-step process before resetting passwords. During testing, you notice that after the customer answers the third verification question, the agent asks them to provide their name again, as if the earlier exchange never happened.
What’s the most likely cause of this behavior?

The prompt lacks instructions telling Claude to remember information across multiple exchanges.

The conversation history isn’t being passed in subsequent API requests.

The verification tool is clearing the agent’s internal state after each successful validation step.

Claude’s memory retention is limited to two conversational turns by default, requiring explicit configuration to extend it.

NO.112 After deploying automated code review, developers report that approximately 35% of flagged findings are false positives falling into consistent patterns: style suggestions contradicting team conventions, security warnings for patterns that are safe in your deployment context, and performance suggestions that would degrade your specific use case. You want to reduce false positives while maintaining the ability to catch genuine issues. Which approach best enables the model to generalize its judgment to novel code patterns it has not seen before?

Implement post-processing that uses keyword matching to filter out findings containing terms such as
“convention,” “context-dependent,” or “trade-off.”

Include few-shot examples in your prompt showing annotated code snippets that distinguish acceptable patterns from genuine issues in each category.

Create a comprehensive written specification of all patterns that should not be flagged, and then include the full documentation in the system prompt.

Add instructions to your system prompt to “be conservative,” “only flag definite issues,” and “consider that some patterns may be intentional.”

NO.113 The document analysis agent has a single analyze_documnet tool that takes a document and a free-text instruction parameter. During evaluation, requests like “extract the key financial metrics” often return narrative summaries, while “summarize the methodology” sometimes returns raw data tables. The synthesis agent reports that 35% of analysis results require re-requests with clarified instructions. What’s the most effective way to improve reliability?

Have the coordinator pre-classify each analysis request before passing instructions to the document analysis agent

Keep the single tool but add an analyze_type enum parameter requiring explicit selection between extraction, summarization, and verification modes

Enhance the tool description with detailed examples showing how different instruction phrasings should map to different output formats

Split the generic tool into purpose-specific tools – extract_data_points, summarize_content, verify_claim_against_source – each with defined input/output contracts

NO.114 You are building a customer support resolution agent using the Claude Agent SDK. The agent handles high- ambiguity requests like returns, billing disputes, and account issues. It has access to your backend systems through custom Model Context Protocol (MCP) tools ( get_customer , lookup_order , process_refund , escalate_to_human ). Your target is 80%+ first-contact resolution while knowing when to escalate.
When the agent calls lookup_order and receives order details showing the item was purchased 45 days ago, how does the agentic loop determine whether to call process_refund or escalate_to_human next?

The order details are added to the conversation and the model reasons about which action to take.

The orchestration layer automatically routes to the next tool based on the order’s status field.

The agent follows a pre-configured decision tree mapping order attributes to specific tool calls.

The agent executes the remaining steps in a tool sequence planned at the start of the request.

NO.115 You are building a structured data extraction system using Claude. The system extracts information from unstructured documents, validates the output using JSON schemas, and maintains high accuracy. It must handle edge cases gracefully and integrate with downstream systems.
Your extraction pipeline occasionally receives responses that cannot be parsed as valid JSON, causing downstream processing failures. The current implementation prompts Claude to return JSON in the response text and then parses it.
What is the most reliable approach to ensure Claude returns valid, schema-compliant structured data?

Add explicit formatting instructions to the prompt with JSON examples, emphasizing that Claude must return only valid JSON with no surrounding text.

Use regular expressions to locate and extract JSON from the response text, handling cases where Claude includes explanatory text around the JSON block.

Define a tool with a JSON schema specifying the expected structure, using tool use to constrain Claude’ s output to schema-compliant JSON.

Implement a retry loop that catches JSON parsing errors and re-prompts Claude with the error details, asking it to correct the malformed output.

NO.116 Your automated review generates many findings per pull request, but developer feedback shows that roughly half are dismissed as “not worth addressing.” Analysis reveals that dismissed findings are often technically accurate but involve minor style preferences or patterns that are acceptable in your codebase. Before adding infrastructure complexity, what prompt-design change could most effectively reduce dismissals while maintaining the detection of genuine issues?

Add explicit criteria defining which issues to report, such as bugs and security defects, and which issues to skip, such as minor style preferences and accepted local patterns.

Implement a secondary classification model that filters Claude’s findings according to predicted developer acceptance.

Ask Claude to rate every finding’s confidence from 1 to 10 and include only findings rated 8 or higher.

Append instructions telling Claude to “only report findings you are highly confident are genuine problems.”

NO.117 A legal department requires Claude to answer only when sufficient evidence exists in retrieved documents. What should Claude do if evidence is insufficient?

Invent a likely answer.

Clearly indicate insufficient information.

Search social media automatically.

Increase creativity.

NO.118 Your control_device tool manages smart home devices through external APIs. When a device doesn’t respond within the timeout period, the tool returns an error. Production logs show that the agent simply tells users “the device is not responding” without offering helpful next steps. Which error response structure would best enable the agent to provide useful follow-up?

Set is_error: true with a structured technical error containing the device ID, timeout duration, and raw API response code for debugging purposes.

Set is_error: true with a brief “Device offline” message and provide a separate tool the agent can call to retrieve context-specific troubleshooting suggestions.

Set is_error: false with an optimistic message indicating the command was dispatched successfully but device acknowledgment is still pending.

Set is_error: true with a message explaining the likely cause and suggesting troubleshooting steps the agent can offer the user.

NO.119 A prompt asks Claude to produce Markdown tables. Which addition MOST increases consistency?

Specify exact column names.

Increase randomness.

Remove formatting instructions.

Omit examples.

NO.120 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.
A security audit requires updating your authentication library from v2 to v3. The migration guide documents breaking changes: authenticate() now returns a Promise instead of accepting a callback, the User type has restructured fields, and three deprecated methods were removed.
Grep shows the library is imported in 45 files across several modules.
What’s the most effective approach?

Create a custom slash command encapsulating the migration transformations, then execute it against each file without prior codebase exploration.

Update the dependency version, run the test suite, and use Claude Code to fix each failure as it appears.

Enter plan mode to explore library usage across modules, map affected code paths, then create a migration strategy before implementing.

Paste the migration guide’s breaking changes into your prompt and use direct execution to update all usages across the 45 files.

NO.121 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.
Your system has been running for 3 weeks and human reviewers have corrected 847 extractions.
Analysis reveals a recurring pattern: when recipes use informal measurements like “a handful” or
“a splash,” the model either invents specific amounts or leaves fields empty–accounting for 23% of all corrections.
How should you use this feedback to improve extraction accuracy?

Fine-tune the model on the 847 corrected extractions.

Add few-shot examples to your prompt demonstrating correct handling of informal measurements–extracting them verbatim rather than converting or omitting them.

Implement a post-processing layer that uses pattern matching to detect informal measurement phrases in source text and automatically populate values when the extraction is empty.

Update your JSON schema to add a “measurement_type” enum field (precise/informal).

NO.122 You are building a multi-agent research system using the Claude Agent SDK. A coordinator agent delegates to specialized subagents: one searches the web, one analyzes documents, one synthesizes findings, and one generates reports. The system researches topics and produces comprehensive, cited reports.
The document-analysis agent has a single analyze_document tool that takes a document and a free-text instruction parameter. During evaluation, requests such as “extract the key financial metrics” often return narrative summaries, while “summarize the methodology” sometimes returns raw data tables. The synthesis agent reports that 35% of analysis results require new requests with clarified instructions.
What is the most effective way to improve reliability?

Enhance the tool description with detailed examples showing how different instruction phrasings should map to different output formats.

Split the generic tool into purpose-specific tools-extract_data_points, summarize_content, and verify_claim_against_source-each with defined input and output contracts.

Keep the single tool but add an analysis_type enum parameter requiring explicit selection between extraction, summarization, and verification modes.

Have the coordinator pre-classify each analysis request before passing instructions to the document- analysis agent.

NO.123 You are building a customer support resolution agent using the Claude Agent SDK. The agent handles high- ambiguity requests like returns, billing disputes, and account issues. It has access to your backend systems through custom Model Context Protocol (MCP) tools ( get_customer , lookup_order , process_refund , escalate_to_human ). Your target is 80%+ first-contact resolution while knowing when to escalate.
Your agent is handling a billing dispute. After calling get_customer and lookup_order , it identifies that the dispute involves a promotional pricing error requiring manager approval-beyond the agent’s authorization level.
How should the workflow handle this mid-process escalation?

Call escalate_to_human , passing only the customer’s original message.

Compile a structured handoff with customer details, order info, and the identified issue before calling escalate_to_human .

Attempt the refund with process_refund anyway, escalating only if the system rejects the transaction.

Persist the complete conversation and tool response history to a database, then call escalate_to_human with a reference ID.

NO.124 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.
Your system must extract event details from calendar invitations and output JSON that strictly conforms to a schema with fields for title, date, time, location, and attendees. Downstream systems reject any malformed or non-conformant JSON.
What approach provides the most reliable schema compliance?

Pre-fill Claude’s response with an opening brace to force JSON output, then complete and parse the response.

Append instructions like “Output only valid JSON matching the schema exactly” and implement retry logic to re-prompt when JSON parsing fails.

Define a tool with your target schema as input parameters and have Claude call it with the extracted data.

Include detailed JSON formatting instructions and the target schema in your prompt, then parse Claude’s text response as JSON.

NO.125 You are building a customer support resolution agent using the Claude Agent SDK. The agent handles high- ambiguity requests like returns, billing disputes, and account issues. It has access to your backend systems through custom Model Context Protocol (MCP) tools ( get_customer , lookup_order , process_refund , escalate_to_human ). Your target is 80%+ first-contact resolution while knowing when to escalate.
A customer contacts the agent about a warranty claim on a power drill. Resolving this requires multiple sequential tool calls: get_customer to look up their account, lookup_order to find the purchase details, and then either process_refund or escalate_to_human depending on warranty eligibility. You’re implementing the agentic loop that orchestrates these steps using the Claude API.
What is the primary mechanism your application uses to determine whether to continue the loop or stop?

You manually set the tool_choice parameter to “none” after the final expected tool call to force Claude to stop requesting tools.

You check the stop_reason field in each API response-the loop continues while it equals “tool_use” and exits when it changes to “end_turn” or another terminal value.

You check whether Claude’s response contains a text content block-if text is present, the agent has produced its final answer and the loop should exit.

You track the number of tool calls made and exit the loop once a preconfigured maximum is reached.

NO.126 You are building a multi-agent research system using the Claude Agent SDK. A coordinator agent delegates to specialized subagents: one searches the web, one analyzes documents, one synthesizes findings, and one generates reports. The system researches topics and produces comprehensive, cited reports.
When analyzing complex legal cases that cite multiple precedents, the document analysis subagent processes each sequentially. A landmark case citing 12 precedents takes over 3 minutes to analyze completely. What’s the most effective way to reduce this latency while preserving the coordinator’s ability to monitor and debug the system?

Create a recursive agent hierarchy where analysis agents subdivide work among child agents until reaching single-precedent granularity

Have the coordinator spawn parallel document analysis subagents, each handling a subset of precedents, then aggregate results before synthesis

Enable the document analysis subagent to spawn its own specialized subagents dynamically when it encounters cases with many citations

Implement a message queue where precedent analysis tasks are processed asynchronously by a pool of worker agents
