AI & Technical question
Design a metrics framework for child-safety safeguards across Claude.ai, API customers, and cloud-hosted deployments. What north-star and guardrail metrics would you use to measure risk prevalence, detection precision/recall, blind spots, and user impact, and how would you distinguish true risk reduction from changes in reporting or traffic mix?

What this question tests
Tests designing a north-star and guardrail metrics framework for safety that can distinguish real risk reduction from artifacts of reporting or traffic mix.
How to approach it
- Define the north-star metric, such as prevalence of confirmed violations per active user, tracked consistently across Claude.ai, API, and cloud surfaces.
- Add detection metrics: precision and recall of the classifier and review system against a held-out labeled set.
- Add blind-spot metrics, such as a periodic audit sample designed to surface what current detection misses.
- Add user-impact guardrails, like false-positive rate on legitimate accounts and appeal overturn rate.
- Normalize metrics per active user or message volume, segmented by surface, so a shift traces to a real change versus a mix shift.
What a strong answer includes
- Separates prevalence, the real problem, from detection rate, what the system catches, since a rising detection rate can mean either.
- Uses a labeled audit sample as ground truth to calibrate precision and recall, not just internal flag counts.
- Normalizes every metric per active user or message to avoid traffic-mix artifacts, such as new API customers skewing raw counts.
- Names a concrete false-positive guardrail threshold, as an illustrative example, to protect legitimate users.
Common mistakes
- Reporting only detection volume, which conflates better detection with worse underlying prevalence.
- Failing to normalize for traffic mix across surfaces, making cross-surface comparisons meaningless.
Likely follow-up questions
- How would you build ground truth for a rare-event prevalence metric?
- What would you do if detection rate rose but you couldn't tell why?

- Offline evals show strong SWE-bench-style gains, but internal dogfooders say the model feels worse on real debugging workflows. Design a launch-gating framework for Claude Code that combines benchmark evals, agentic task suites, transcript review, and limited-rollout criteria. What would you measure, how would you weight conflicting signals, and what thresholds would block launch?Anthropic · AI & Technical · Hard
- Researchers deliver a model that is materially better at code generation in lab evals, but developer success rates inside Claude Code do not improve. How would you diagnose whether the gap comes from prompting, tool use, context management, latency or reliability, or the eval itself, and what changes would you make to convert model gains into user-visible outcomes?Anthropic · AI & Technical · Hard
- Across many agentic coding tasks, Claude Code shows a recurring failure mode like looping, weak planning, or bad tool selection. How would you isolate whether the issue is in the base model, prompting, tool interfaces, or task decomposition, and what reusable infrastructure would you build to catch and prevent this class of regressions?Anthropic · AI & Technical · Hard
- Researchers say Claude Science is useful for workflows like protein structure analysis and chemistry research, but not consistently trustworthy. How would you define target model behaviors, build workflow-grounded evals with research and engineering, surface the highest-risk failure modes, and set a clear launch-readiness bar for broader rollout?Anthropic · AI & Technical · Hard
