Orchestration:
Choose prompt template and model, assemble context, call tools, validate output, retry and fall back.
In → out:
request → validated, schema-checked response
Common failures:
invalid output, retry storms, runaway tool loops
Metrics:
step latency, retries, validation failures
Security:
separate trusted instructions from untrusted text; tool allowlists
Scaling:
stateless workers, queues
