AI Agent Maintenance Services: Keeping Production AI Agents Reliable

Launching an AI agent is the easy part. Keeping it accurate, safe and cost-efficient month after month is where most teams struggle. Nestack Agent Care offers AI agent maintenance services that run your production agents like production systems, across goals, workflows, tools, LLMs, evaluations, guardrails, human review and business outcomes.

What ongoing AI agent maintenance covers

• Continuous monitoring and alerting of LLM usage, latency and cost.
• Quality, safety and drift checks so performance changes are caught as conditions evolve.
• Evaluations of final outputs, individual steps and selected trajectories, with industry-specific coverage.
• Trace, tool-action and guardrail investigation when a session fails or is flagged as high risk.
• Human review of sampled and flagged sessions.
• Incident coordination, with targeted re-evaluation after material fixes and evidence-linked verification before an issue is closed.
• Cost-efficiency reviews across models, retries and tool usage.

Built on industry playbooks

Nestack Agent Care works from a catalogue of failure modes and 23 industry playbooks, covering sectors such as accounting, banking, healthcare and insurance, plus department playbooks for teams like customer support and finance. Each playbook lists the risks monitored, the evaluations run and the procedures followed.

Works above your existing stack

Agent Care is a managed operating process, not another platform to buy. It connects the traces, evaluations, guardrail events, human feedback and incidents you already have into one maintenance workflow, so platform subscriptions stay separate.

Care levels

Maintenance is priced per agent, per month, based on complexity and business impact: Care Essential for low-risk internal agents, Care Plus for production agents handling customer or business workflows, and Care Enterprise for regulated or mission-critical agents with a 30-minute critical-incident acknowledgement. See Agent Care pricing for current details.
