Capstone: Productionize Kintsu Agent

Mission

Take the fragile happy-path agent in Kintsu Agent through a production hardening review.

Required controls

• Deadlines, bounded retries, backoff, and fallback for dependency calls
• Idempotency for refunds and webhook processing
• Durable workflow checkpoints and restart recovery
• Structured logs, metrics, traces, correlation IDs, and actionable alerts
• Schema and tool-argument validation with human escalation
• A versioned regression eval suite
• Canary thresholds, feature flags, rollback, and an incident runbook

Failure demonstration

Inject slow CRM calls, lost refund responses, process crashes, malformed model output, and a bad V2 rollout. Capture evidence showing the original failure and the hardened behavior.

Interview artifact

Prepare a five-minute explanation: system boundary, highest-risk failure, reliability trade-off, evidence from one incident, and what you would build next at ten times the traffic.
