How to Build SLOs for AI Agents Before They Break Enterprise Workflows

The AI notepad for people in back-to-back meetings (Sponsor)

Most AI note-takers just transcribe what was said and send you a summary after the call.

Granola is an AI notepad. And that difference matters.

You start with a clean, simple notepad. You jot down what matters to youand, in the background, Granola transcribes the meeting.

When the meeting ends, Granola uses your notes to generate clearer summaries, action items, and next steps, all from your point of view.

Then comes the powerful part: you can chat with your notes. Use Recipes (pre-made prompts) to write follow-up emails, pull out decisions, prep for your next meeting, or turn conversations into real work in seconds.

Think of it as a super-smart notes app that actually understands your meetings.

Most enterprises are still measuring AI systems like traditional software.

• Is the API available?

• Is latency acceptable?

• Are requests returning errors?

• Is the infrastructure healthy?

Those questions still matter. But they are not enough for AI agents.

An AI agent can be online, fast, and technically successful while still breaking an enterprise workflow. It can return a 200 response and still escalate the wrong incident. It can complete a tool call and still update the wrong record. It can generate a polished answer and still expose sensitive data. It can appear helpful while quietly creating operational risk.

That is the uncomfortable truth for SREs and platform engineers deploying AI in enterprise environments: uptime is not the same as reliability.

When AI agents begin acting inside production workflows, teams need a new reliability model. They need service-level objectives, or SLOs, designed for systems that reason, retrieve context, call tools, and make decisions under uncertainty.

The goal is not to make AI agents perfect. The goal is to define what “reliable enough” means before the agent breaks something important.

Why AI Agents Need Their Own SLOs

SRE teams already understand the value of SLOs. In Google’s SRE framework, a service-level indicator, or SLI, is a quantitative measure of some aspect of a service. A service-level objective, or SLO, is the target value or target range for that measure.

That structure works because it forces teams to define reliability from the user’s point of view.

For a traditional web service, that might mean request latency, availability, error rate, or durability. For an internal API, it might mean successful response rate and p99 latency. For a payment service, it might mean completed transaction rate and fraud-control performance.

But AI agents are different because their failure modes are different.

A traditional service fails when it is unavailable, slow, or returning errors. An AI agent can fail when it misunderstands intent, retrieves the wrong context, calls the wrong tool, leaks sensitive information, hallucinates a policy, gets trapped in a loop, or performs an action that is technically allowed but operationally wrong.

That means agent reliability has to measure outcomes, not just infrastructure health.

For SREs, this is the first mindset shift: an AI agent is not reliable just because it responds. It is reliable when it completes the right task, within the right boundary, with the right level of confidence, at an acceptable cost, and with a recoverable failure path.

Defining the Workflow Before the Metric

The biggest mistake teams make is trying to define AI SLOs at the model level.

• They ask: What is the model’s accuracy?

• What is the hallucination rate?

• What is the latency of the LLM call?

Those are useful signals, but they are not enough. Enterprise AI agents do not operate as isolated models. They operate inside workflows.

A support triage agent has a different reliability profile from an incident response agent. A coding assistant has a different risk model from a finance automation agent. A document summarizer has different failure modes from an agent that can modify cloud infrastructure.

Before defining SLOs, platform teams should define the agent’s job.

• What workflow does the agent support?

• Who depends on its output?

• What systems can it access?

• What tools can it call?

• What actions can it perform?

• What is the cost of a wrong action?

• What should happen when confidence is low?

• When should a human take over?

Only after answering those questions should teams define SLIs.

For example, an incident response agent should not be measured only by response latency. It should be measured by whether it identifies the correct affected service, summarizes the incident accurately, recommends safe next steps, and escalates to the right team.

A customer support agent should not be measured only by resolution speed. It should be measured by whether the resolution is correct, compliant, safe, and accepted by the customer or human reviewer.

A platform automation agent should not be measured only by successful tool execution. It should be measured by whether the action was authorized, reversible, scoped, and aligned with the user’s intent.

In other words, AI agent SLOs should start with the workflow, not the model.
