Direct answer
AI agents can be reliable for critical read-and-draft workflows when external writes require approval, material changes are tested against evaluations, and STOP states reach a human owner with context—not when autonomy is maximized.
Key points
- Target draft reliability, not unsupervised execution.
- Rerun representative evaluations after material changes to a model, prompt, or connector.
- Keep source references beside generated claims; if evidence is missing, ask or stop.
- Give every STOP state an accountable owner and a safe next step.
Reliability stack
- Scoped connectors and least-privilege access.
- Confidence thresholds and source checks.
- Human approval for writes and irreversible actions.
- A human runbook for STOP states, with an explicit owner.
- Regression evaluations after material workflow changes.
A failure drill: missing source data
Example scenario—not a report of a Pattern customer deployment: an agent prepares a draft from a business record, but a connector returns an empty required field or an unexpected response shape.
- Validate input: Check the record identity and required fields before proceeding.
- Stop unsafe work: If validation fails, prevent external writes and preserve the response, validation error, and last safe state.
- Bound retries and hand off: Retry only errors expected to be temporary, with a small attempt cap. If the data remains incomplete, give a named human owner the source record, missing fields, checks already performed, and a safe next action.
- Measure recovery: Track incomplete or invalid results, retries, human handoffs, and successful recoveries. Set thresholds and investigate recurring patterns.
NIST's AI RMF Playbook recommends selecting metrics for significant AI risks and documenting what cannot be measured, as described in NIST AI RMF Playbook — Measure.[1] This drill is a proposed operating check, not a claim about measured Pattern production results.
