Your agent needs to handle a request that requires balancing thoroughness against the user's evident impatience.
How would you design the system to balance thoroughness against user impatience?
General Medium

Answer:

  1. Read impatience signals: Detect when the user wants speed, so you can adapt.

  2. Lead with the answer: Give the essential result first, so impatient users are satisfied fast.

  3. Offer depth optionally: Make thoroughness available without forcing it, so both needs are served.

  4. Match effort to urgency: Scale thoroughness to how much time the user has, so it fits.

  5. Let users choose: Allow explicit fast-versus-thorough selection, so impatience is respected.

Your agent works, but its behavior subtly depends on the order tools are defined, and reordering them changes outputs unexpectedly.
How would you design the system to make behavior independent of incidental ordering?
General Medium

Answer:

  1. Identify order sensitivity: Detect where ordering incidentally affects behavior, so it's addressed.

  2. Make selection order-independent: Choose tools by relevance, not position, so order doesn't matter.

  3. Test with reordering: Vary orderings in tests, so hidden dependencies surface.

  4. Normalize presentation: Present tools and context consistently, so incidental order is removed.

  5. Ground behavior in content: Base decisions on what things are, not where they appear, so ordering is irrelevant.

Your agent needs to serve a request where the answer's usefulness depends on how it's framed for the specific audience.
How would you design the system to frame answers for the target audience?
General Medium

Answer:

  1. Identify the audience: Determine who the answer is for, so framing can suit them.

  2. Adapt framing: Adjust emphasis, detail, and language to the audience, so the answer lands.

  3. Match the purpose: Frame for how the answer will be used, so it's actionable in context.

  4. Adjust technical level: Fit terminology to audience expertise, so it's neither over nor under their heads.

  5. Confirm audience when unclear: Ask who the answer is for if ambiguous, so framing isn't a guess.

Your agent works, but it can't tell the difference between a user testing it and a user with a real need, and treats tests as real.
How would you design the system to handle test versus genuine requests appropriately?
General Medium

Answer:

  1. Detect test signals: Recognize when a request seems exploratory or testing, so handling can adjust.

  2. Handle both correctly: Serve genuine needs fully while not over-committing to tests, so neither is mishandled.

  3. Avoid harmful actions on tests: Don't take real consequential actions for apparent tests, so testing is safe.

  4. Provide a test mode: Offer an explicit way to test safely, so users don't have to trigger real behavior.

  5. Don't dismiss real needs: Avoid wrongly treating genuine requests as tests, so real users are served.

Your agent needs to handle a request that would benefit from information it could proactively fetch, but it only uses what's explicitly provided.
How would you design the system to proactively gather helpful information?
General Medium

Answer:

  1. Identify useful information: Recognize what additional data would help, so proactive fetching is targeted.

  2. Fetch relevant context: Retrieve or look up helpful information automatically, so answers are richer.

  3. Balance proactivity against cost: Fetch only when the value justifies it, so you don't over-gather.

  4. Avoid unnecessary fetching: Skip proactive gathering when provided info suffices, so you stay efficient.

  5. Be transparent: Note when you've pulled in extra information, so users understand the basis.

Your agent works, but users game it — crafting inputs to extract behavior or benefits it wasn't meant to provide.
How would you design the system to resist gaming and abuse?
General Medium

Answer:

  1. Detect gaming patterns: Recognize inputs designed to exploit the agent, so abuse is caught.

  2. Enforce intent, not just rules: Judge the purpose behind requests, so users can't game the letter of the rules.

  3. Rate-limit exploitation attempts: Throttle suspicious behavior, so gaming is slowed.

  4. Constrain exploitable behavior: Bound what the agent will do, so there's less to game.

  5. Monitor and adapt: Track new gaming tactics and close them, so resistance keeps pace.

Your agent needs to make a decision quickly, but gathering the ideal context takes too long for the latency budget.
How would you design the system to make good decisions within a tight context budget?
General Medium

Answer:

  1. Prioritize high-value context: Gather the most decision-relevant context first, so limited time is well spent.

  2. Set a context budget: Cap how much context-gathering time is allowed, so latency is respected.

  3. Decide on sufficient context: Act once you have enough, so you don't over-gather.

  4. Cache to accelerate: Reuse context from prior requests, so gathering is faster.

  5. Degrade gracefully: Make a reasonable decision with partial context, so tight budgets don't block answers.

Your agent works, but its answers depend on a knowledge base where some content is authoritative and some is aspirational or draft.
How would you design the system to distinguish authoritative from draft content?
General Medium

Answer:

  1. Tag content status: Mark documents as authoritative, draft, or deprecated, so status is known.

  2. Prefer authoritative sources: Ground answers in approved content, so drafts don't drive answers.

  3. Exclude or flag drafts: Keep unfinished content out of retrieval or clearly marked, so it isn't treated as fact.

  4. Filter by status at query time: Retrieve only appropriate-status content, so answers rest on the right basis.

  5. Surface content status: Tell users when an answer draws on non-authoritative content, so they judge accordingly.

Your agent needs to handle a request where following the user's explicit instruction would produce a worse outcome than a slight deviation.
How would you design the system to balance instruction-following against outcome quality?
General Medium

Answer:

  1. Follow instructions by default: Honor explicit requests, so users stay in control.

  2. Flag likely-suboptimal instructions: Point out when an instruction may hurt the outcome, so users can reconsider.

  3. Suggest the better alternative: Offer the improved approach, so users see the option.

  4. Defer to the user's choice: Let them decide after being informed, so you don't override them silently.

  5. Deviate only with consent: Change course only when the user agrees, so trust is preserved.

Your agent is mature, but each incident is handled ad hoc, and you learn nothing systematic from failures.
How would you design the process to systematically learn from incidents?
General Medium

Answer:

  1. Conduct postmortems: Analyze each incident's root cause, so lessons are extracted.

  2. Add regression coverage: Encode each incident as a test, so it can't recur silently.

  3. Fix root causes: Address underlying causes, not just symptoms, so classes of failure are prevented.

  4. Track incident patterns: Look across incidents for recurring themes, so systemic issues surface.

  5. Feed learnings back: Turn lessons into design and process improvements, so the system gets more resilient over time.

Your agent needs to handle a request that spans your system's boundary into a partner's system with different reliability guarantees.
How would you design the system to handle differing reliability across a partner boundary?
General Medium

Answer:

  1. Don't assume partner reliability: Treat the partner side as potentially unreliable, so you're defensive.

  2. Add boundary resilience: Use timeouts, retries, and fallbacks at the boundary, so partner issues are contained.

  3. Validate across the boundary: Check partner responses, so their errors don't corrupt your side.

  4. Degrade when the partner fails: Function partially without them, so you're not fully dependent.

  5. Monitor the boundary: Track partner-side health, so their problems surface as yours.

Your agent works, but its quality depends on retrieval parameters that were set once and never revisited as the corpus grew tenfold.
How would you design the process to keep retrieval parameters tuned as the corpus evolves?
General Medium

Answer:

  1. Re-evaluate periodically: Revisit parameters as the corpus changes, so they stay optimal.

  2. Monitor retrieval quality: Track metrics over time, so parameter drift surfaces.

  3. Re-tune on degradation: Adjust parameters when quality drops, so growth doesn't erode retrieval.

  4. Scale parameters with size: Adapt top-k and thresholds to corpus growth, so they fit the new scale.

  5. Automate tuning where possible: Continuously optimize parameters, so they don't go stale.

Your agent needs to handle a task that requires strict ordering, but the underlying async system doesn't guarantee it.
How would you design the system to enforce ordering over an unordered async substrate?
General Medium

Answer:

  1. Add sequence numbers: Tag items with order, so sequence is recoverable despite async delivery.

  2. Buffer and reorder: Hold items until they can be processed in order, so ordering is enforced.

  3. Wait for prerequisites: Block a step until its predecessor completes, so dependencies are respected.

  4. Detect out-of-order arrival: Recognize when order breaks, so it's corrected, not processed wrongly.

  5. Make ordering-independent where possible: Design steps that don't need strict order, so the problem shrinks.

Your agent works, but its answers assume the user has more (or less) background than they actually do.
How would you design the system to match answers to the user's actual background?
General Medium

Answer:

  1. Gauge background: Infer the user's knowledge level, so answers can match it.

  2. Calibrate assumed knowledge: Neither over-explain nor under-explain, so the answer fits.

  3. Adjust terminology: Match jargon to their level, so answers are accessible without being condescending.

  4. Offer to adjust: Let users signal if it's too basic or advanced, so calibration corrects.

  5. Adapt over the conversation: Refine based on their responses, so matching improves.

Your agent needs to serve a request where the user's real question is embedded in a long, rambling message.
How would you design the system to extract the actual request from verbose input?
General Medium

Answer:

  1. Identify the core request: Extract what the user actually wants, so you answer the real question.

  2. Filter the noise: Set aside tangential content, so it doesn't distract from the ask.

  3. Handle multiple requests: Detect if the rambling contains several asks, so none is missed.

  4. Confirm on ambiguity: Verify the extracted request when unclear, so you don't answer the wrong part.

  5. Address relevant context: Use pertinent detail from the message, so extraction doesn't lose useful information.

Your agent works, but its performance depends on a preprocessing step that silently fails on certain inputs, corrupting everything downstream.
How would you design the system to catch preprocessing failures early?
General Medium

Answer:

  1. Validate preprocessing output: Check the result of each preprocessing step, so silent failures are caught.

  2. Fail loudly: Surface preprocessing errors rather than passing bad data on, so they don't corrupt downstream.

  3. Handle problem inputs: Manage inputs that break preprocessing, so they're handled, not silently mangled.

  4. Test on diverse inputs: Exercise preprocessing with varied data, so failure cases surface.

  5. Monitor preprocessing health: Track failure rates, so silent problems become visible.

Your agent needs to handle a request where the same word means different things in different parts of your domain.
How would you design the system to handle domain-specific term ambiguity?
General Medium

Answer:

  1. Use context to disambiguate: Interpret terms by their surrounding context, so meaning is resolved.

  2. Maintain a domain glossary: Define term meanings per context, so ambiguity is documented.

  3. Detect ambiguous terms: Recognize when a term could mean multiple things, so it's not resolved blindly.

  4. Confirm on genuine ambiguity: Clarify when context doesn't resolve it, so you don't guess wrong.

  5. Ground in the right context: Retrieve context matching the intended meaning, so answers use the correct sense.

Your agent works, but you can't safely give it more autonomy because you have no way to constrain what it does with that autonomy.
How would you design the system to grant autonomy within safe bounds?
General Medium

Answer:

  1. Define autonomy limits: Specify what the agent may do independently, so bounds are explicit.

  2. Gate high-impact actions: Require approval for consequential steps, so autonomy excludes the risky.

  3. Constrain the action space: Limit available actions to safe ones, so autonomy can't cause harm.

  4. Monitor autonomous behavior: Watch what the agent does independently, so overreach is caught.

  5. Expand autonomy incrementally: Grant more as trust is earned, so autonomy grows safely.

Your agent needs to handle a request that requires it to admit a previous answer it gave was wrong, but it doubles down instead.
How would you design the system to correct its own prior errors gracefully?
General Medium

Answer:

  1. Detect prior errors: Recognize when new information contradicts a past answer, so errors are caught.

  2. Acknowledge the correction: Admit the earlier answer was wrong, so trust is maintained.

  3. Provide the correct answer: Replace the error with the right information, so the user is served.

  4. Avoid doubling down: Don't defend a wrong answer, so errors aren't compounded.

  5. Explain what changed: Clarify why the answer is now different, so the correction reads as reasoning.

Your agent is mature, but your monitoring only tells you when things break, not when they're slowly getting worse.
How would you design the system to detect gradual degradation before it becomes failure?
General Medium

Answer:

  1. Track trends, not just thresholds: Watch metrics over time, so slow decline is visible before it breaks.

  2. Baseline normal behavior: Know what healthy looks like, so drift stands out.

  3. Alert on sustained movement: Flag gradual negative trends, so degradation is caught early.

  4. Monitor leading indicators: Watch signals that precede failure, so you get advance warning.

  5. Investigate slow drifts: Diagnose gradual changes before they compound, so failure is prevented.
