Question 30

A coordinator's user-facing report must include exact citations. However, the delegated synthesis specialist is told to omit all sources and produce unsupported prose. The two role prompts now conflict. What should be changed?

  1. Keep the omit-sources instruction because specialist prompts always outrank the final report requirements.
  2. Delete all source metadata from the coordinator after retrieval to keep the writer's context small.
  3. Allow the synthesis agent to create reference URLs from memory when the final report is assembled.
  4. Align the delegated synthesis brief with the coordinator's evidence and citation requirements.

Explanation

Correct Answer

D:

The coordinator must propagate nonnegotiable output requirements into specialist instructions. A synthesis agent told to omit sources cannot reliably satisfy a final reporting contract that demands exact citations, even if the evidence workers collected suitable references. The coordinator should provide source metadata, require claim-level attribution, and define an acceptance check for the final report. That consistent contract prevents a local worker preference from silently overriding the user-facing research standard.

Incorrect Answers

A:

The delegated role is a means of fulfilling the coordinator's task, not a separate authority to change its acceptance criteria. Suppressing citations would produce a result that violates the report's explicit evidence requirement. The coordinator should correct the contradictory brief instead of treating the worker's local instruction as justification for an unsourced deliverable.

B:

Removing citations before synthesis makes precise attribution impossible even if the final prompt later asks for it. Context can be reduced by passing only relevant excerpts and reference identifiers, rather than entire raw documents. Discarding provenance would amplify the very conflict between the specialist's output and the final report contract.

C:

A URL that resembles a legitimate source is not proof that it supports the attached claim. Reconstructing references from memory breaks the chain from retrieved evidence to conclusions. The coordinator should carry actual document IDs and source locations through the handoff and reject any unsupported citations before publication.

Question 31

One researcher cites a revenue figure from a current website, while another cites a different figure from a two-year-old archived report. The report aggregator stores only the number and company name. How should it preserve the evidence?

  1. Keep each claim with its source identifier, observation period, and relevant document location before comparison.
  2. Overwrite the older figure with the newest value and erase the older source reference.
  3. Treat every source mentioning the same company as if it measured the same reporting interval.
  4. Combine the values into an average and cite only the current website.

Explanation

Correct Answer

A:

A numeric claim is meaningful only when its measurement period and provenance are known. The coordinator should carry the source URL or document ID, publication or observation date, units, and location alongside the reported figure. Those fields allow the synthesis step to determine whether the differences represent a real contradiction or simply different years. Combining naked numbers by company name would hide temporal context and risk an inaccurate trend or citation in the final report.

Incorrect Answers

B:

Using the current figure may be appropriate for a present-day snapshot, but deleting older provenance prevents the report from explaining change over time. The differing values could be correct for their respective periods. The aggregator should preserve both measurements and their dates before selecting any number for the requested analysis.

C:

A shared company label does not imply matching fiscal years, currencies, definitions, or publication dates. The archived report is explicitly older than the website figure, so direct equality is not a safe assumption. Source-specific metadata is necessary to avoid misleading comparisons or fabricated contradictions.

D:

Averaging across reporting periods can obscure temporal movement rather than describe either observed year. Citing one website for a calculation based on two sources would also misrepresent provenance. A valid synthesis states which values came from which periods and applies a justified comparison method when a combined metric is actually requested.

Question 32

A multi-agent research report now meets its requested geographic coverage, topic checklist, citation standard, and accuracy checks. The writer suggests another source-search round solely to adjust wording. What should the coordinator do?

  1. Remove all acceptance criteria so the agent can decide intuitively whether it feels finished.
  2. Close evidence collection using the explicit completion criteria and handle any optional prose edits without further source delegation.
  3. Always launch one additional research cycle after every successful synthesis, regardless of evidence gaps.
  4. Discard the approved report and ask all specialists to restart in case a better wording exists.

Explanation

Correct Answer

B:

The report already satisfies the substantive acceptance conditions, so another retrieval cycle has no identified information gap to close. The coordinator should distinguish editorial polish from evidence incompleteness, finish the supported answer, and avoid unnecessary specialist work. If a later edit introduces a new claim, it can be checked against the existing evidence or trigger a targeted lookup. Merely improving style does not justify repeating source gathering after the required coverage and citations are complete.

Incorrect Answers

A:

Without explicit coverage and evidence requirements, the coordinator cannot reliably distinguish a complete answer from a superficially polished one. The scenario already provides objective conditions that the report meets. Dropping them would make future stopping decisions less consistent and undermine quality assurance for more complex investigations.

C:

An unconditional extra pass creates avoidable cost and may introduce unneeded facts that complicate a finished report. The scenario states that geography, topic scope, and citation criteria are already met. Completion should follow those objective checks, not a fixed habit of re-delegating after success.

D:

A possible stylistic improvement does not invalidate supported research findings. Restarting source work wastes accepted evidence and might create new inconsistencies without changing the substantive answer. The coordinator can perform normal editorial refinement on the existing report while retaining its citations and verified claims.

Question 33

A Claude Agent SDK research coordinator defines a specialist agent but does not allow the delegation capability in its tool permissions. The team follows an older tutorial referring to `Task`, while current SDK releases show a renamed delegation tool. What is the correct fix?

  1. Enable every SDK tool, including unrestricted shell and file writes, to guarantee delegation works.
  2. Rewrite each prompt to mention `Task` repeatedly, without changing any permitted-tool configuration.
  3. Enable the authorized delegation tool in the parent configuration—`Agent` on current SDK versions, accounting for legacy `Task` naming where applicable.
  4. Keep the delegation tool forbidden and expect the specialist to execute automatically because its definition exists.

Explanation

Correct Answer

C:

A specialist definition alone does not make delegation possible when the parent agent lacks permission to invoke the delegation capability. Current Claude Agent SDK documentation uses `Agent` in emitted tool-use blocks and notes that older interfaces called it `Task`, with compatibility naming in some metadata. The team should configure permitted delegation according to its installed version and grant the specialist only the tools its role requires. This fixes the capability mismatch without broadening unrelated file or network permissions.

Incorrect Answers

A:

Delegation requires a specific authorized capability, not an indiscriminate expansion of the entire tool surface. Broad mutation access would introduce unnecessary risk for a read-only researcher. Configure the applicable `Agent` or legacy `Task` entry and give each specialist only the tools relevant to its actual tasks.

B:

Prompt wording cannot grant a tool that the runtime has not allowed. It also ignores the documented version difference between current `Agent` tool-use names and older `Task` references. The correct solution is to inspect the installed SDK behavior and configure the tool permissions accordingly, then test a genuine delegated call.

D:

A named agent configuration describes a possible role; it does not override the parent's allowed tool set. With delegation unavailable, the coordinator cannot call the specialist in the normal workflow. The application must reconcile the configured capability and permissions rather than relying on the presence of an unused agent definition.

Question 34

An Agent SDK web-research specialist needs search and read functions, but its inherited configuration also permits arbitrary file deletion. The team wants to reduce the blast radius of untrusted pages. What should be changed?

  1. Keep deletion permissions but add a polite instruction asking the researcher not to use them.
  2. Remove all search and read capabilities so the specialist cannot encounter malicious content.
  3. Let the web pages decide which filesystem permissions the specialist should receive.
  4. Define an explicitly scoped research subagent with read/search tools only and a task-specific description.

Explanation

Correct Answer

D:

The specialist's legitimate objective is evidence collection, not modification of application files. A role definition should state which sources it may inspect, what evidence to return, and which tools it can use. Removing unnecessary mutation permissions limits damage if retrieved web content contains misleading instructions or the agent misinterprets a request. The parent coordinator can separately authorize later changes through an appropriate implementation role rather than giving the researcher unrestricted filesystem access.

Incorrect Answers

A:

An instruction can guide behavior, but it is weaker than denying an unneeded tool at the capability boundary. The scenario's risk is an unnecessary destructive permission available to a specialist processing external content. Removing that capability ensures accidental or injected delete requests cannot be executed by the research role.

B:

Eliminating the very tools needed for research would prevent the specialist from carrying out its assigned evidence task. The safer design is least privilege, not a role with no useful functionality. Retain permitted retrieval and inspection tools while excluding unrelated write or delete operations.

C:

Retrieved pages are untrusted task data, not authorities for configuring local tool access. Allowing a webpage to request deletion privileges would create a prompt-injection path from external content to the host environment. The application owner should define specialist permissions independently of materials that the specialist later reads.

Question 35

A synthesis subagent is expected to produce a cited risk summary, but the coordinator hands it only a list of conclusions without the original document names, URLs, or extraction context. Which TWO items should be included in the handoff? Select TWO answers.

  1. Only a message saying that retrieval has finished successfully.
  2. The private source documents in full, even sections unrelated to the assigned report.
  3. The validated claim-level findings and excerpts needed to support the summary.
  4. The source identifiers and relevant page, section, or timestamp metadata for those findings.
  5. A request to create plausible-looking citation links when the final report is assembled.

Explanation

Correct Answers

C:

The synthesizer needs the substance of what the evidence specialists found, not merely a task-completed flag or a conclusion with no support. Selected excerpts and verified numeric findings give it a defensible basis for comparing risks. The coordinator can trim irrelevant raw documents to protect context limits while preserving passages that support each required claim. This makes synthesis evidence-driven rather than a reconstruction of missing research from plausibility.

D:

Attribution is part of the evidence, not a decorative addition at final formatting time. Recording URLs or document IDs together with relevant locations and dates lets the synthesis agent connect each claim to its underlying source. Those fields also help distinguish different versions of a report or statements made in separate periods. Passing provenance alongside content enables the final cited summary to remain traceable through the specialist boundary.

Incorrect Answers

A:

A completion flag says nothing about which claims were found or what sources support them. The synthesis specialist would still lack the content needed to evaluate risk or attach citations. A proper handoff transmits both findings and their supporting identifiers, rather than treating workflow status as substantive research evidence.

B:

Unbounded raw content may contain sensitive or irrelevant material and can consume the synthesis agent's context window. The coordinator should transfer the necessary validated excerpts and provenance while respecting access restrictions. Wholesale document sharing is not required to preserve citation quality and increases avoidable exposure across agent roles.

E:

Generated-looking links do not show that the cited documents contain the claimed facts. Because the coordinator already has real source metadata, asking the writer to invent citations would introduce an avoidable attribution failure. The report needs verifiable evidence references, not links guessed from topic or organizational naming patterns.

Question 36

An aggregation layer combines numerical claims from several analyst agents but retains only a metric label and value. Reviewers can no longer tell whether a figure came from a spreadsheet page or a government report. What evidence structure should it use?

  1. Sort all results by numeric value and combine adjacent rows as if they shared a source.
  2. Store each claim with its source URL or document ID, page or section, and observation period.
  3. Keep only the metric value and rely on the final writer to remember which source produced it.
  4. Assign the same generic citation URL to every figure from the research session.

Explanation

Correct Answer

B:

Claim-level provenance enables later reviewers and the synthesis agent to trace a number to the actual place where it was reported. The observation period matters because similarly named metrics can refer to different years, snapshots, or versions. Preserving a structured evidence record makes aggregation reversible and permits conflict checks before numerical comparisons. The system can still create a compact summary, but it should not collapse distinct sources into an anonymous value that no one can verify.

Incorrect Answers

A:

Numerical proximity does not prove two measurements refer to the same entity, period, or source. Such merging could collapse unrelated figures and remove contradictory evidence. Aggregation should operate on explicit claim identity and provenance fields rather than incidental ordering in a result table.

C:

Separate agents do not have dependable implicit access to one another's earlier retrieval context. Once identifiers and locations are dropped, the writer may guess attribution or attach an unrelated link. A structured handoff is essential when the report must defend numerical claims to a reviewer.

D:

A session-wide landing page does not establish which page, table, or document supports a particular figure. Different analysts may have consulted unrelated sources or reporting dates. Attaching one citation to every value would blur important distinctions and could falsely imply that the generic page verifies unsupported numbers.

Question 37

A research coordinator needs a regulatory analysis and an engineering-feasibility analysis for the same proposed product. The two evidence searches are independent, but the final recommendation depends on both. How should specialists be invoked?

  1. Let the regulatory specialist write and publish the entire product recommendation alone.
  2. Send both specialists an identical unbounded prompt without distinguishing their evidence requirements.
  3. Delegate the two clearly scoped analyses concurrently and reconcile their outputs after both return.
  4. Wait for the engineering analysis to finish before permitting the regulatory search to start.

Explanation

Correct Answer

C:

Regulatory research and engineering feasibility can proceed in parallel because neither needs the other's intermediate findings to begin. The coordinator should provide separate goals, source constraints, and expected evidence fields to the respective specialists. Once both results arrive, it can evaluate whether the implementation is technically viable and legally permissible, citing each source family accurately. This preserves the final integration dependency while reducing unnecessary waiting during independent evidence collection.

Incorrect Answers

A:

Legal evidence is only one part of the requested decision; a regulator-focused worker may not have validated engineering feasibility. Publishing before the technical results arrive would omit a required perspective. The coordinator should remain responsible for combining both analyses into the final product recommendation.

B:

Undifferentiated task briefs can make specialists duplicate work or neglect a needed source family. The workflow benefits from one policy-focused and one implementation-focused investigation. Explicit scopes and output requirements let the coordinator integrate complementary findings rather than reconcile two broad but inconsistent essays.

D:

There is no stated prerequisite linking those two retrieval tasks, so serial execution would increase latency without improving correctness. A regulator's rules can be researched independently of the technical architecture analysis. The coordinator should synchronize before the final recommendation, not before each separate investigation begins.

Question 38

Two specialists will inspect a database migration: one maps dependency risks, and the other assesses security consequences. The roles need different repository access and evidence. How should the coordinator prepare parallel delegation?

  1. Give both specialists the full parent context and every available write-capable tool by default.
  2. Send each specialist only its name and expect it to discover the correct migration and constraints.
  3. Run the analyses in parallel but allow one specialist to silently overwrite the other's evidence packet.
  4. Issue separate role-specific briefs containing only relevant references, constraints, and permitted tool scopes.

Explanation

Correct Answer

D:

Parallel specialists should receive enough shared background to analyze the same migration, but their duties and privileges differ. The dependency reviewer may need read access to migration files and call graphs, while the security reviewer needs schema, policy, and exposure evidence. Explicit instructions and tool restrictions prevent one role from inheriting unnecessary mutation capabilities. The coordinator later reconciles both analyses against the common migration goal without assuming their separate contexts were automatically synchronized.

Incorrect Answers

A:

Excess context can expose unrelated material, while unrestricted mutation privileges exceed the needs of an investigative analysis. The scenario specifies distinct roles and permissions, so identical broad grants erase useful boundaries. Role-specific least privilege allows both analyses without expanding the risk of accidental or injected changes.

B:

A role label is not an adequate task brief when several migrations, schemas, or authorization boundaries could exist. The coordinator has relevant references and constraints that should be passed explicitly. Omitting them increases the risk that the specialists inspect different artifacts or reach conclusions based on incompatible assumptions.

C:

Concurrency should reduce waiting, not eliminate provenance or role separation. If one worker mutates the other's findings, the coordinator cannot tell which source supports a given migration risk. Keep returned evidence and statuses distinct until the integration step, where conflicts can be adjudicated explicitly.

Question 39

A parent customer-support conversation contains personal messages and financial identifiers. The coordinator wants a data-analysis subagent to calculate a summary from sanitized extracted facts. What is the safest handoff?

  1. Provide only the required sanitized facts and restrict the subagent to approved analysis tools.
  2. Forward the entire conversation transcript because subagents automatically need all parent history.
  3. Give the data analyst refund-execution credentials in case it decides to correct the figures.
  4. Remove every fact from the handoff and ask the analyst to estimate the customer's financial history.

Explanation

Correct Answer

A:

A specialist should receive data and capabilities proportionate to its assigned task. Here the analyst can compute the needed summary from extracted facts without seeing the customer's full private conversation or identifiers. The coordinator should construct a minimal evidence packet, apply access restrictions, and keep sensitive records in the protected support context. This reduces inadvertent disclosure and limits the specialist's blast radius while preserving the information necessary for accurate analysis.

Incorrect Answers

B:

The analysis does not require personal chat messages or financial identifiers, so including them expands sensitive exposure without improving the calculation. Context boundaries are intended to support scoped delegation. A minimal fact packet is sufficient and more defensible than granting a specialist broad access simply because the parent possesses the data.

C:

A summary calculation is read-only analytic work, not authorization to move money. Granting financial action credentials introduces an unnecessary side-effect capability and could permit an erroneous or injected tool call. The coordinator should reserve refund operations for separately guarded support workflows with verified approval.

D:

Privacy protection does not require abandoning the legitimate analysis; the task can use sanitized, purpose-limited facts. Without data, a calculated summary would become speculation rather than an answer to the customer's actual records. The right boundary preserves necessary evidence while excluding unrelated sensitive content.

Question 40

A coordinator delegates 'research this product' to a specialist without defining deliverables. The worker returns a broad but shallow paragraph instead of the evidence and comparison the report needs. What should change?

  1. Publish the shallow paragraph because any returned specialist message counts as successful completion.
  2. Specify the goal, mandatory evidence fields, scope limits, and completeness tests in the delegated task.
  3. Ask the worker to 'research harder' while leaving its objective and expected output undefined.
  4. Increase the number of identical specialists, each receiving the same vague request.

Explanation

Correct Answer

B:

Subagents perform better when the coordinator describes an observable outcome rather than an open-ended topic. A targeted brief can require sources, dates, comparison criteria, unresolved questions, and a bounded summary format. The coordinator can then evaluate the returned work against those acceptance conditions and request follow-up only where coverage is missing. This addresses the vague assignment that produced shallow output without requiring every specialist to see the entire parent conversation.

Incorrect Answers

A:

A tool or agent returning text means it executed, not that the result satisfies the report's requirements. The missing evidence and comparison are substantive quality defects. The coordinator must validate returned findings against the delegated goal and request targeted completion rather than treating message receipt as proof of research success.

C:

More emphatic wording does not tell the specialist which claims need verification or how much coverage the report requires. The existing failure stems from missing task structure, not an insufficiently motivated agent. Concrete evidence fields and completion criteria provide a testable direction that generic encouragement does not.

D:

Parallel duplication could produce several shallow paragraphs without covering the required comparison. Nothing in the scenario indicates that worker count is the limiting factor. The coordinator should first clarify differentiated scope and acceptance criteria, then decide whether multiple independent subtasks are useful.
