Question 130

A research subagent has already retried a rate-limited endpoint twice and exhausted its local budget. It must report to the coordinator. What should it include?

  1. Provide failure category, query, retry count, last status, completed partial findings and next permitted action.
  2. Report only 'done' to keep the parent context small.
  3. Silently restart retries from zero in another subagent.
  4. Omit partial findings so the coordinator always starts fresh.

Explanation

Correct Answer

A:

The coordinator can decide a targeted fallback without discarding successes.

Incorrect Answers

B:

A success-sounding status hides missing evidence.

C:

This evades the budget and duplicates unsuccessful calls.

D:

Already verified data should not be thrown away without reason.

Question 131

One research database is offline, but two other sources returned valid evidence. The agent currently reports 'no data exists'. What is the correct error semantics?

  1. Substitute a cached database summary without recording the outage or checking whether it covers the requested period.
  2. Report the database as unavailable and preserve qualified partial findings from the working sources.
  3. Turn the outage into a successful empty result.
  4. Discard all successful source findings to maintain uniformity.

Explanation

Correct Answer

B:

Missing access to one source is not proof the topic lacks evidence.

Incorrect Answers

A:

Past evidence can be reused only with clear version, scope and limitations. Silent substitution would misrepresent inaccessible current data as verified.

C:

That conflates execution failure with factual absence.

D:

Valid evidence remains useful with transparent coverage limits.

Question 132

A token for a private document service expired. The requester receives an authorization error, which the agent interprets as a server outage. How should the error be handled?

  1. Assume every 401 or 403 means the file was deleted.
  2. Retry identical unauthenticated requests until the network changes.
  3. Replace the failure with a successful document summary.
  4. Classify authentication or permission failure correctly and route through approved token refresh or access review.

Explanation

Correct Answer

D:

Credentials must be repaired or renewed before a prohibited fetch can succeed.

Incorrect Answers

A:

Access status does not prove object absence.

B:

Permission checks will continue to reject the same expired token.

C:

The file was not read, so a verified summary is impossible.

Question 133

An MCP tool emits only 'Operation failed' after a query, leading the agent to retry unsafe actions. What response shape would help?

  1. Keep the generic error and rely on the model's intuition.
  2. Return the full backend stack trace as the only tool-result text without identifying whether the requested state change committed.
  3. Replace the message with 'success' regardless of the backend result.
  4. Provide a stable machine-readable error category, human-readable cause, retryability and relevant operation ID.

Explanation

Correct Answer

D:

Structured categories enable appropriate recovery and audit.

Incorrect Answers

A:

The model cannot infer authorization or side-effect status from an untyped failure.

B:

A stack trace can expose implementation detail while leaving safe retry semantics unresolved. A recoverable tool error needs a stable code, outcome status and next action.

C:

False status hides failed work.

Question 134

A payment tool refuses a refund because the account's available balance is insufficient. What should the assistant's tool layer report?

  1. Return a successful receipt with amount zero.
  2. Increase requested credit until the call stops failing.
  3. Treat the event as a network timeout and repeat immediately.
  4. A nonretryable business-condition failure with accurate balance/limit semantics and authorized alternatives.

Explanation

Correct Answer

D:

The account rule must be addressed before executing another payment.

Incorrect Answers

A:

That can falsely indicate a completed refund.

B:

A larger debit cannot fix insufficient balance.

C:

Insufficient funds are not transient connectivity problems.

Question 135

Three parallel source fetches complete, but one returns an error and the other two provide useful documents. Which aggregation payload is correct?

  1. Drop all results to make the outcome uniformly failed.
  2. Include both successful source results and the failed source identifier, error and unresolved coverage.
  3. Include only the fastest source and ignore the remaining responses.
  4. Pretend the failed source was empty and mark coverage complete.

Explanation

Correct Answer

B:

Partial success is usable only when incompleteness stays explicit.

Incorrect Answers

A:

The two successful fetches need not be wasted.

C:

Arrival order does not determine relevance.

D:

Execution failure is not a valid no-match finding.

Question 136

A tool wrapper forwards a provider exception as a normal success-shaped message without isError. What failure mode does this create?

  1. Claude may treat execution failure as valid task data; the wrapper must mark and describe the error explicitly.
  2. The model will automatically infer error status from any empty content.
  3. No problem exists because result formatting cannot influence decisions.
  4. Forward the error flag but omit the cause and action context to reduce token use.

Explanation

Correct Answer

A:

The error flag and context distinguish unavailable service from an empty successful answer.

Incorrect Answers

B:

Empty content also occurs in legitimate queries.

C:

Downstream tool handling depends on accurate success/failure semantics.

D:

A bare error indicator hides whether input, permission or availability caused failure. The agent needs a concise actionable category and context.

Question 137

An MCP request uses 2026/31/10 where the schema requires ISO 8601; the agent keeps repeating it. Which tool response should be returned?

  1. A nonretryable validation error identifying the date field and accepted ISO 8601 format.
  2. A success response with an arbitrarily corrected date.
  3. A silent empty result interpreted as no relevant records.
  4. A transient timeout to encourage longer backoff.

Explanation

Correct Answer

A:

Specific correction feedback prevents identical malformed retries.

Incorrect Answers

B:

Unannounced interpretation can change the query range.

C:

The requested query was not validly executed.

D:

Formatting errors are deterministic until inputs change.

Question 138

An outbound refund call times out after submission; the client cannot tell whether the transaction committed. Select TWO independent safeguards before an uncertain payment retry.

  1. Declare permanent failure because no response was received.
  2. Query transaction status using the original idempotency key before attempting a controlled retry.
  3. Treat the timeout as proof the customer's account is empty.
  4. Issue a second refund using a new transaction key immediately.
  5. Block any new charge with a different idempotency key until the original write status is resolved.

Explanation

Correct Answers

B:

The first write may have succeeded despite the lost response.

E:

Looking up the first attempt establishes whether it committed. Preventing a fresh request key closes a separate path to charging twice while the original outcome is unknown.

Incorrect Answers

A:

Unknown completion is not evidence of rejection.

C:

Network failure provides no account balance evidence.

D:

A new key can create a duplicate charge or refund.

Question 139

A report synthesis specialist can call eighteen tools but uses only read_claims and check_citations. What configuration is best?

  1. Leave all tools permitted but shorten their descriptions in the specialist's prompt to reduce context cost.
  2. Grant the specialist payment and delete rights for future convenience.
  3. Expose only those necessary read and verification tools to the synthesis role, with other work delegated through the coordinator.
  4. Keep every tool available because more choices always improve accuracy.

Explanation

Correct Answer

C:

Narrow allowlists reduce tool confusion and the impact of malicious instructions.

Incorrect Answers

A:

Reducing prompt text does not remove execution authority. A narrow allowlist is the effective permission boundary for a synthesis worker.

B:

Mutating business authority is unrelated to summarizing evidence.

D:

Unneeded capabilities increase selection ambiguity and risk.

Question 140

A code-search subagent can delete repository branches although it is only asked to inspect call sites. What should the architect do?

  1. Remove destructive capabilities from the subagent's allowed tools and its underlying credentials.
  2. Add a system prompt saying deletion is discouraged, but keep admin access.
  3. Give all search tools shared administrator tokens to ease setup.
  4. Permit destructive repository operations during search-only analysis, relying on backups if an accidental mutation occurs.

Explanation

Correct Answer

A:

A read task should not be able to mutate repository state.

Incorrect Answers

B:

Prompt warnings cannot enforce permission boundaries.

C:

Broad credentials expand the damage from a single mistaken call.

D:

Restoration is not a replacement for least privilege. A search-only role should not have the ability to delete branches at all.
