Executive Summary
Agentic key risk indicators are the metrics organisations use to monitor the behaviour, risk profile, and operational performance of autonomous AI agents.
Agentic systems do not operate in a steady state. As they learn and adapt, small behavioural changes can accumulate and alter their risk profile.
Effective governance therefore requires organisations to monitor the direction and speed of this AI behavioural drift before it moves beyond risk appetite.
Agentic key risk indicators, sometimes described more generally as AI key risk indicators, provide the operational evidence needed to monitor AI agent risk and ensure regulatory compliance.
This article sets out 12 practical principles for designing effective agentic KRIs and illustrates them through 20 worked examples across 5 common agentic risks. It is preparation for our next article when we will use these metrics to show how to operationalise KRIs on a major AI agent platform.
Agentic Monitoring Cannot Assume a Steady State
As an AI agent learns and adapts, its risk profile can change as its behaviour drifts, often emerging as small incremental changes.
Because of this, you should not assume a steady state, but instead monitor its behaviour to ensure it does not drift beyond your risk appetite or AI risk tolerance.
Without a focus on the direction and speed of drift, you will lack effective operational governance and may end up allowing your agents to spend money on unnecessary tool use, need to dedicate time to remediation, and reduce the likelihood of securing the benefits of agentic AI.
Build your regulatory defence
Not only are indicators of developing agentic risks operationally essential and commercially prudent, without them, regulatory compliance would also be either challenging or impossible. Under the EU AI Act, without recorded evidence that you are monitoring and measuring your AI agent’s risks over time, you could not prove to a regulator that your system is safe to operate.
Meanwhile, Article 6 of the EU Digital Operational Resilience Act (DORA) explicitly requires firms to track key risk metrics for technology and AI systems, so without agentic key risk indicators, a firm would be in breach the regulation.
Similarly, the NIST AI Risk Management Framework’s ‘Measure’ function requires continuous monitoring of AI behaviour and auditors certifying you for ISO 42001 will require documented evidence that your AI risks are being tracked and acted upon.
12 Principles for Effective Agentic Key Risk Indicators
With risk metrics being essential from operational and regulatory perspectives, designing effective agentic key risk indicators is a core part of our Pre-Deployment Agentic Risk Assessment. This article provides detailed guidance on the topic.
Agentic key risk indicators represent a specialised form of operational risk metric designed for autonomous AI systems. Similar to traditional key risk indicators used in enterprise risk management, they track measurable signals that indicate whether an AI agent’s behaviour is drifting beyond acceptable limits.
To begin, we outline 12 principles for setting effective agentic key risk indicators, before applying them across a batch of worked examples for five common agentic risks.
- Operationalise Your Risk Appetite Statement – the purpose of a KRI is to implement the organisation’s risk appetite statement at the operational level, so make sure your KRIs align with and support it.
- Complete Coverage – map each risk control from your risk assessment to a KRI to ensure your ongoing monitoring will give you complete coverage.
- Give each KRI Two Thresholds – a ‘tolerance threshold’, which acts as an early warning that your limit is being approached and an ‘appetite limit’, which is your hard boundary and the point when you implement your breach procedure.
- Regular Agentic KRI Reviews – setting your KRIs and their thresholds is not a one-time activity because your risk appetite and agentic capability will evolve at the same time as your agent learns and adapts, so commit to reviewing your agentic KRIs regular.
- Set Initial Thresholds Conservatively – as we learned from studying how we delegate autonomy to other non-humans, we grant it slowly and only when earned, so be prudent and adjust later if appropriate.
- Asymmetric Treatment– apply stricter thresholds for higher risk workflows.
- Be Sensitive to Context – consider factors like transaction volumes, materiality, and downstream impact when setting limits.
- Track Your Agentic Capability Too – your KRIs should cover not only agent behaviour, but also the ongoing effectiveness of the organisation’s ability to respond.
- Accuracy and Reliability – expect AI outputs to be at least as reliable as existing processes and remain within monitored accuracy thresholds. Where confidence cannot be established, outputs must be withheld and escalated.
- Prohibited as well as Permitted Behaviours – enable a zero tolerance by prohibited behaviours for looking out for them as well as monitoring the performance of permitted behaviours.
- Errors, Exceptions, and Rework – demonstrate a low tolerance for errors and a zero tolerance for errors that are not detected within defined monitoring windows. Expect all errors to trigger a review and trace rework to a specific cause (data, logic, configuration, or prompt).
- Explainability and Traceability – every output should be traceable to source data, KPI logic version, time of execution, and a responsible human reviewer. Outputs that cannot be explained in plain English should be considered outside risk appetite.
Worked Examples Across 5 Agentic Risks
The aim of this section is to illustrate how agentic key risk indicators represent an evolution in AI risk monitoring (not a revolution) from many current in-use metrics. To achieve this, we have selected 5 common risks – hallucination, behavioural drift, security breach, compliance violation, and operational resilience – and provided a batch of KRIs for each of them.
There are 20 in total. Some may be novel, like KRI 7 (Processing Pattern Anomalies), while you may already be familiar with others, such as KRIs 2 and 9 (False Positive Rate and Unauthorised Access Attempts).
To ensure quality and consistency, each metric comprises standard fields: #, title, definition, calculation methodology, data source(s), frequency, and the two thresholds. In practice, we include additional fields to cover actions for breaching a threshold, required response times, the metric owner, and the escalation path.

Selecting And Setting The Right KRIs
To recap, designing agentic key risk indicators is a vital part of AI risk monitoring and your Pre-Deployment Agentic Risk Assessment, which you could summarise as identifying risks, designing controls, and setting KRIs.
In this article, we illustrated worked examples for five common agentic risks. However, there are, of course, more agentic risks we would include for real:
- Some would be general, e.g. rising tool use and costs, or shrinking human intervention rates.
- While others would be specific to the use case, e.g. boundary-testing behaviours, deviations from expected decision paths, unusually confident actions.
Identifying the most valuable agentic key risk indicators for your strategy is an important skill for ensuring you do not overload yourself with data. In our next article, we use these 20 KRIs to show how to operationalise metrics on a major AI agent platform.
So, if you would like some help with selecting and setting specific KRIs or ensuring the data is properly collected, collated and interrogated to guarantee your regulatory defensibility, book a free consultation with us.
Frequently Asked Questions About Agentic Key Risk Indicators
Agentic key risk indicators are metrics used to monitor the behaviour and risk profile of autonomous AI agents. They track signals such as accuracy, behavioural drift, security events, and compliance controls so organisations can detect emerging risks before an AI system moves beyond defined risk appetite.
Organisations need agentic key risk indicators because AI agents learn and adapt over time, which means their behaviour can gradually drift from expected outcomes. Without measurable indicators of this drift, risk managers cannot detect emerging problems or demonstrate effective oversight of autonomous AI systems.
Agentic key risk indicators monitor AI risk by measuring patterns in system behaviour such as output accuracy, anomaly rates, access attempts, and response times. By tracking these metrics over time, organisations can identify behavioural drift, security threats, or compliance issues before they escalate into operational failures.
Several frameworks require organisations to monitor AI risks, including the EU AI Act, the Digital Operational Resilience Act (DORA), the NIST AI Risk Management Framework, and ISO/IEC 42001. These frameworks expect organisations to measure and track AI system behaviour to demonstrate safe and controlled operation.
Common agentic key risk indicators measure output quality, behavioural consistency, security events, compliance traceability, and operational resilience. Examples include recommendation accuracy rates, anomaly detection metrics, unauthorised access attempts, audit trail completeness, and system availability indicators. Other areas to consider include boundary-testing behaviours, deviations from expected decision paths, unusually confident actions, rising tool use and costs, and shrinking human intervention rates.
