Your agent needs to handle requests that could be interpreted as either a question or a command, and it guesses wrong half the time.
How would you design the system to disambiguate questions from commands?
General Medium

Answer:

  1. Classify intent type: Determine whether input is a query or an action request, so handling matches.

  2. Use context: Draw on conversation flow to disambiguate, so ambiguous phrasing resolves.

  3. Confirm before acting: Verify intent for consequential commands, so wrong guesses don't cause actions.

  4. Ask when truly unclear: Clarify genuinely ambiguous input, so you don't guess.

  5. Learn from patterns: Improve classification from past cases, so accuracy grows.

Your agent's quality is inconsistent because it depends on retrieved context whose quality you never actually measure.
How would you design the system to measure and act on context quality?
General Medium

Answer:

  1. Score retrieved context: Assess relevance and sufficiency, so context quality is known.

  2. Gate generation on quality: Proceed only with adequate context, so weak context doesn't produce weak answers.

  3. Improve retrieval on low quality: Re-retrieve or expand when context is poor, so quality improves before generating.

  4. Flag low-context answers: Signal when context was weak, so users judge reliability.

  5. Track context quality over time: Monitor it as a metric, so degradation surfaces.

Your agent needs to operate where regulations require certain decisions be made by humans, but it currently automates everything.
How would you design the system to enforce mandatory human decision points?
General Medium

Answer:

  1. Identify mandated decisions: Map which decisions legally require humans, so they're never automated.

  2. Gate them explicitly: Block automation on those decisions, so a human must act.

  3. Present clearly for decision: Give the human what they need to decide, so the gate is functional, not a rubber stamp.

  4. Record human involvement: Log that a human decided, so compliance is provable.

  5. Fail closed: Never proceed without the required human step, so the mandate holds.

Your agent needs to handle a scenario where the correct answer changes depending on when it's asked, but it answers as if facts are static.
How would you design the system to handle time-dependent answers?
General Medium

Answer:

  1. Anchor to current time: Establish when "now" is, so time-dependent answers are correct.

  2. Fetch time-sensitive data live: Pull current values at query time, so answers reflect the present.

  3. Qualify with timeframe: State what time the answer applies to, so it's not mistaken for permanent.

  4. Avoid stale assumptions: Don't treat time-varying facts as static, so answers stay accurate.

  5. Handle future and past: Interpret temporal references correctly, so "next week" resolves properly.

Your agent produces good individual answers, but users doing a series of related tasks have to re-establish context every time.
How would you design the system to carry context across related tasks?
General Medium

Answer:

  1. Persist task context: Store context beyond a single task, so related work reuses it.

  2. Link related tasks: Connect tasks in a series, so context flows between them.

  3. Retrieve relevant history: Pull prior task context when starting a related one, so users don't re-explain.

  4. Detect task relationships: Recognize when tasks connect, so context is carried automatically.

  5. Let users reference prior work: Support references to earlier tasks, so continuity is natural.

Your agent needs to work with an unreliable network where requests are sometimes duplicated or arrive out of order.
How would you design the system to handle unreliable network delivery?
General Medium

Answer:

  1. Deduplicate requests: Use request IDs to catch duplicates, so repeated delivery doesn't double-process.

  2. Handle out-of-order arrival: Sequence requests explicitly, so order doesn't corrupt state.

  3. Make processing idempotent: Ensure repeats are safe, so duplicate delivery causes no harm.

  4. Acknowledge reliably: Confirm receipt clearly, so senders know not to resend unnecessarily.

  5. Timeout and retry sensibly: Handle lost requests without amplifying duplicates, so recovery is clean.

Your agent's answers are correct but it presents every one at maximum length, exhausting users who wanted a quick check.
How would you design the system to match response length to actual need?
General Medium

Answer:

  1. Infer needed depth: Judge from the question how much answer is wanted, so length fits.

  2. Default to concise: Start short and expand on request, so users aren't overwhelmed.

  3. Match length to complexity: Give simple questions short answers, so effort matches need.

  4. Let users control length: Offer to elaborate, so depth is available on demand.

  5. Lead with the essential: Front-load the core answer, so length doesn't bury the point.

Your agent needs to process a request that spans multiple user permissions, and it's unclear whether it should act with the union or intersection of those permissions.
How would you design the system to handle permission boundaries in multi-context requests?
General Medium

Answer:

  1. Default to least privilege: Use the intersection of permissions, so access never exceeds any single boundary.

  2. Evaluate per resource: Check permissions for each accessed resource, so access is precise.

  3. Fail closed on ambiguity: Deny when permissions are unclear, so you don't over-grant.

  4. Make boundaries explicit: Define how permissions combine, so behavior is predictable.

  5. Audit access decisions: Log what was permitted and why, so boundaries are verifiable.

Your agent needs to combine deterministic rules with LLM judgment, but the two sometimes disagree and it's unclear which should win.
How would you design the system to arbitrate between rules and model judgment?
General Medium

Answer:

  1. Define precedence: Decide when rules override the model and vice versa, so conflicts have a clear resolution.

  2. Let rules handle the certain: Use deterministic logic where correctness is known, so the model doesn't second-guess facts.

  3. Let the model handle nuance: Defer to judgment on ambiguous cases, so rigid rules don't misfire.

  4. Flag disagreements: Surface when rules and model conflict, so hard cases get attention.

  5. Escalate the unresolvable: Route genuine conflicts to a human, so neither is forced wrongly.

Your agent works, but its success depends on assumptions about the environment that occasionally change without warning, silently breaking it.
How would you design the system to detect when environmental assumptions break?
General Medium

Answer:

  1. Make assumptions explicit: Document what the agent depends on, so they can be checked.

  2. Validate assumptions at runtime: Verify environmental conditions hold, so breaks are detected.

  3. Monitor for drift: Watch for changes in the environment, so silent shifts surface.

  4. Alert on violations: Flag when an assumption breaks, so you react before failures cascade.

  5. Fail safely on broken assumptions: Degrade gracefully when conditions don't hold, so breaks don't cause silent wrong behavior.

Your agent needs to handle requests that arrive faster than it can process, but dropping them loses work and queuing them adds unbounded delay.
How would you design the system to handle request arrival rate exceeding processing rate?
General Medium

Answer:

  1. Apply backpressure: Signal upstream to slow down, so intake matches capacity.

  2. Bound the queue: Cap queue size, so delay stays bounded.

  3. Shed low-priority load: Drop or defer less important requests, so critical ones are served.

  4. Scale processing: Add capacity when sustained, so the rate gap closes.

  5. Communicate delays: Tell users about wait times, so expectations are managed.

Your agent's answers depend on assumptions about the user that are sometimes wrong, leading to confidently misdirected responses.
How would you design the system to handle uncertain assumptions about the user?
General Medium

Answer:

  1. Make assumptions explicit: State what you're assuming, so wrong ones are visible.

  2. Verify when it matters: Confirm key assumptions, so critical answers aren't misdirected.

  3. Avoid over-assuming: Ask rather than guess on important factors, so you don't build on shaky ground.

  4. Adapt when corrected: Update quickly when an assumption proves wrong, so you recover.

  5. Ground in known data: Base assumptions on actual user information, so they're better founded.

Your agent needs to work continuously, but memory usage grows over long-running sessions until it eventually crashes.
How would you design the system to manage memory in long-running processes?
General Medium

Answer:

  1. Bound context growth: Cap how much state accumulates, so memory doesn't grow unbounded.

  2. Release stale state: Free data no longer needed, so memory is reclaimed.

  3. Externalize large state: Store bulk data outside process memory, so the process stays lean.

  4. Detect leaks: Monitor memory over time, so growth is caught before crashes.

  5. Recycle processes: Restart workers periodically, so accumulated state is cleared safely.

Your agent needs to reason over a decision that involves competing objectives, but it optimizes one and ignores the others.
How would you design the system to balance competing objectives in decisions?
General Medium

Answer:

  1. Make objectives explicit: Define all the goals in tension, so none is silently ignored.

  2. Weight them: Assign relative importance, so the balance reflects priorities.

  3. Reason over trade-offs: Have the agent consider objectives jointly, so it optimizes the whole, not one part.

  4. Surface the trade-off: Show what was balanced, so users can adjust.

  5. Evaluate on all objectives: Measure outcomes across every goal, so single-objective optimization is caught.

Your agent works well but you're getting reports that it behaves differently for different users in ways that seem unfair.
How would you design the system to detect and address inconsistent treatment across users?
General Medium

Answer:

  1. Measure across user groups: Compare behavior for different users, so disparities surface.

  2. Identify unjustified differences: Distinguish fair personalization from unfair inconsistency, so real problems are found.

  3. Ground shared behavior: Anchor core behavior to consistent logic, so it doesn't vary unfairly.

  4. Audit for bias: Check whether differences correlate with sensitive attributes, so unfairness is caught.

  5. Monitor fairness continuously: Track cross-user consistency, so drift toward unfair treatment surfaces.

Your agent needs to hand a task to a human and get it back, but the human's changes and the agent's assumptions conflict on return.
How would you design the system to handle bidirectional human-agent handoffs cleanly?
General Medium

Answer:

  1. Preserve context both ways: Pass full state to the human and back, so nothing is lost in either direction.

  2. Reconcile changes: Merge human edits with agent state, so conflicts are resolved deliberately.

  3. Detect divergence: Recognize when human changes conflict with assumptions, so they're caught.

  4. Re-validate on return: Check the task state when it comes back, so the agent adapts to changes.

  5. Track the handoff: Log who did what, so the exchange is auditable.

Your agent's cost is dominated by a small number of very expensive requests, but you don't know upfront which requests will be expensive.
How would you design the system to predict and manage expensive requests early?
General Medium

Answer:

  1. Estimate cost upfront: Predict a request's likely cost before running, so expensive ones are flagged.

  2. Use early signals: Detect complexity from the request itself, so prediction is possible before execution.

  3. Gate high-cost requests: Add checks or approval for predicted-expensive ones, so they're controlled.

  4. Set per-request caps: Bound cost regardless of prediction, so surprises are contained.

  5. Learn from history: Refine predictions using past cost data, so estimation improves.

Your agent needs to handle inputs in formats you didn't anticipate, and unexpected formats cause it to crash or misinterpret data.
How would you design the system to handle unexpected input formats robustly?
General Medium

Answer:

  1. Detect format: Identify the input's actual format, so handling matches it.

  2. Parse defensively: Handle unexpected structures gracefully, so surprises don't crash.

  3. Normalize to a standard: Convert varied formats into a common form, so downstream logic is consistent.

  4. Fail gracefully on unknowns: Return a clear message for unparseable input, so failures are clean.

  5. Learn from surprises: Add newly seen formats to handling, so coverage grows.

Your agent occasionally produces a response that would be perfect in isolation but is redundant because it repeats what it already told the user earlier.
How would you design the system to avoid redundant repetition across a conversation?
General Medium

Answer:

  1. Track what's been said: Maintain a record of prior content, so you know what's already covered.

  2. Check before repeating: Compare new content against history, so redundancy is caught.

  3. Reference instead of repeat: Point back to earlier answers, so you don't restate them fully.

  4. Add incremental value: Ensure each response advances the conversation, so nothing is pure repetition.

  5. Summarize when recapping: If recap is needed, condense it, so it's not a verbatim repeat.

Your agent needs to work with users who each have different tolerance for wait time, but it applies one latency-quality trade-off to everyone.
How would you design the system to adapt the latency-quality trade-off per user?
General Medium

Answer:

  1. Learn user tolerance: Gauge how much each user values speed versus quality, so the trade-off fits them.

  2. Let users choose: Offer a fast-versus-thorough option, so users control the balance.

  3. Adapt by context: Favor speed for quick tasks and quality for deep ones, so the trade-off suits the moment.

  4. Route accordingly: Send requests to fast or thorough paths per preference, so the balance is applied.

  5. Monitor satisfaction: Track whether the trade-off matches user expectations, so it can be tuned.
