Claude Agent SDK: Production Patterns

Demo agents fail fast. Production agents fail slowly, expensively, and in ways that evade testing.

Five Non-Negotiable Production Patterns

PATTERNWHY
Durable State Outside ProcessStore in Postgres/Redis, not in-memory. Treat SDK session as ephemeral.
Hard Cost CapsPer-task, per-user, per-tenant. In the agent harness, not a billing alert.
Circuit BreakersStop runaway loops before they drain budget. Max iterations + token budget.
Tool PermissioningPer-tool human approval: auto/ask/deny. Write actions always require approval.
Observability from Day 1Traces, spend ledger, audit log flowing before production.
