Models
Model stack, observability, and evals

- Trace visibility across prompts, tool calls, latency, and cost.
- Audit trail for approvals, failures, retries, and handoffs.
- Operational analytics that help teams understand run quality over time.
Eval coverage
- Regression datasets for critical workflows and prompts.
- Task-success or rubric-based scoring on agent outcomes.
- Human-review loops to validate edge cases before broad rollout.
Governance
Data boundaries and fallbacks
- Retention windows, model-training policy, and tenant isolation should be explicit.
- Per-tool permissions and least-privilege access matter for production rollout.
- Confirm PII handling, redaction controls, and region or residency options.
LangWatch should document how runs pause, retry, escalate, or hand off when confidence drops or a tool step fails.
