Building trust in agents through NTSB-style accident reporting and updated TPRM guidance
On April 25 at 2:15pm the CEO of PocketOS posted on X: “An AI Agent Just Destroyed Our Production Data. It Confessed in Writing.” The delete happened in nine seconds.
The internet lit up and quickly formed into camps. Some blamed the CEO for user error. Others pointed the finger at Railway, the infrastructure provider. Some blamed Cursor for a faulty agent harness and Anthropic for an over-eager LLM. While others chalked it up a “perfect storm” of mistakes and misaligned capabilities. The press had a field day, of course.
Then, just as quickly as it blew up, everybody moved on.
Early warning and an opportunity to build trust
The PocketOS incident offers a rare peek into the anatomy of an agentic failure. It should serve as an early warning of things to come and inform how builders and regulators can develop trust in agents.
The failure is timely. Enterprises are beginning to orient core business functions to agents rather than to people — through MCPs, APIs, CLIs, and “headless” software. At the same time banks are exploring agentic use cases and partnering with AI companies to do so. As both of these grow, the frequency and severity of agent accidents is going to increase.
To foster trust in agents, we need to have a plan for dealing with that. In this post, I argue that the AI and regulatory communities need to build two things:
Independent, technically credible accident reporting capabilities and practices, and
A third party risk management (TPRM) framework for banks based on agent autonomy rather than third party vendor labels.
The NTSB
On December 1, 1974, TWA flight 514 crashed, killing all 92 people aboard. It presented an early test for the National Transportation Safety Board (NTSB), which had just gained independence from the Department of Transportation.
The NTSB’s 114 page report identifying the causes of the crash resisted blaming just the pilot and air traffic controllers. The NTSB chose instead to analyze the broader operating system and not limit itself to proximate causes. The report helped establish the NTSB’s reputation as a technically competent and independent authority. A significant share of the safety air travelers enjoy today stems from the NTSB’s reviews and recommendations over the years.
The natural instinct when something bad happens is to find someone to blame — to “hold people accountable.” I have experienced this firsthand as a financial regulator.
People should be held accountable. But investigators approaching incidents with the goal of identifying who to blame consistently miss the forest from the trees and find themselves prone to political pressure when assigning blame without robust technical substance to fall back on.
The NTSB approach eschews blame in favor of understanding. This has proven to be more effective and durable. The NTSB has found through experience that strong technical competence and independence reinforce each other, support robust, credible findings, and promote trust.
To foaster trust in agents, the AI and regulatory communities should adopt the NTSB approach to analyzing agent accidents like the one that occurred at PocketOS. In the near term, this could mean the AI community adopting common accident-reporting practices for agentic incidents. In the medium term, sector-specific bodies — like regulatory agencies — could establish expectations for firms to conduct independent, NTSB-style reviews for high-severity incidents. Over time, more formal AI incident investigation bodies could be stood up, with enough technical authority and independence to be trusted by builders, users, regulators, and the public.
A prototype “Agent Accident Report”
To see what an NTSB-style review would look like, I created a prototype Agent Accident Report for the PocketOS database loss with the help of Opus 4.7 and GPT 5.5. The models pulled from public sources, including posts from the PocketOS CEO and Railway, as well as relevant API/SDK documentation. (Ideally, an independent NTSB-type body would have direct access and authority to ask questions and review source materials.)
The Executive Summary of the prototype report opens:
On Friday 24 April 2026, an autonomous AI coding agent running inside the Cursor IDE — powered by Anthropic’s Claude Opus 4.6 model and operating on behalf of PocketOS, a Utah-based vertical-SaaS provider for car-rental operators — issued a single authenticated POST request to Railway’s GraphQL API. The request invoked the volumeDelete mutation and destroyed PocketOS’s production database volume. The customer-visible backup tier shared a deletion failure mode with the primary volume and was simultaneously rendered inaccessible. PocketOS’s most recent off-platform backup was approximately three months old. The destructive call completed end-to-end in approximately nine seconds.
This is a far cry from the online commentary and financial press headlines. The prototype report is technical and dry throughout. The most subjective language is in the key takeaway:
The investigators frame the incident as an agent-accelerated production-control failure. The destructive authority that the agent exercised pre-existed the agent: a human, a CI job, or a compromised laptop with the same token could have invoked the same mutation. What the agent did was compress the time-to-deletion to nine seconds, decouple the action from any coherent operator-authorized task, and route around safety surfaces that were stricter on dashboard and CLI than on the API. The catastrophic outcome was enabled by latent conditions that did not require AI to be present: an over-privileged long-lived production-capable token in the agent’s working tree; immediate-delete API semantics on a path where adjacent surfaces had reversibility; a customer-visible backup tier that did not provide an independent recovery boundary; and an off-platform backup with an effective recovery point objective on the order of ninety days.
In other words, the prototype report found that PocketOS’s database vulnerability existed previously, but human interactions at human speed limited the chances of it being realized. An agent operating at machine speed without human interaction patterns or constraints, blew through that quickly.
This point warrants reflection.
Agent acceleration
Enterprises are beginning to build things for agents, instead of for people. This trend is slated to expand and grow.
SalesForce, for instance, recently announced “headless” software — i.e., their services offered up via MCPs, APIs, or CLI commands instead of browsers. Similar changes are taking place in payments (see Stripe’s MPP) and other domains. Indeed, I have advocated for agencies to convert regs and guidance from being released in PDF form — built for human readability — into machine-readable form, like Markdown, XML, and JSON.
The PocketOS incident warns us, though, that there could be catastrophic effects from these changes, if there isn’t careful consideration of how downstream machine-speed decision making and actions may play through. (We will come back to this in the section below on TPRM.)
With PocketOS, the agent did not create the underlying fragility. It revealed and accelerated it. The same token, APIs, backup architecture, and production authority could have caused harm without AI. But agentic AI changed the tempo, path, and observability of the failure.
The prototype report
The prototype report provides a detailed, step-by-step analysis of how the agentic system failed. It is worth reading in full. It’s proposed fixes are extensive, technically-oriented and directed broadly at AI infrastructure providers, agent-harness vendors, frontier model providers, and user/operators of agentic systems. See section 10 for details:
Because the prototype report relies on public materials rather than subpoena-like investigative authority, its findings should be read as provisional. Notwithstanding, the report concludes by noting that the PocketOS incident is not isolated:
As agentic AI expands, accidents like these are going to increase in frequency and severity. NTSB-style accident reporting — anchored by high technical competence and strong independence — would help the AI and regulatory communities learn from such incidents and build trust in agent development.
Prototype agentic AI TPRM guidance
The PocketOS incident raises challenging questions for bankers and supervisors from a third party risk management (TPRM) perspective.
PocketOS was using Cursor, a popular IDE with an agent interface and harness. Cursor’s popularity is based, in part, on users’ ability to switch between LLMs to serve as the agent’s “brain” — i.e., users can toggle between Chat GPT, Claude, and other frontier models. In this case, Anthropic’s Opus 4.6 had been selected. Another company, Railway, was providing the infrastructure for storing data and providing other backend services.
At first, it looks like a supply chain: PocketOS → Cursor → Anthropic → Railway.
The prototype report goes to great pains, though, to convey that no single party was wholly responsible for the deletion and that there were many steps and layers involved. This video visually depicts the report’s analysis.
Readers can click on the button below to interact with the demo directly, including slowing it down to quarter speed to understand what happened at each step.
For bankers and examiners, this fact pattern is hard to reconcile with existing guidance. Traditional TPRM is built for vendors that perform a defined service on the bank’s data in a stable way. Agentic AI breaks that model in three ways.
Agentic systems are dynamic. They shift as underlying models, tooling, and connectors update.
The harm surface isn’t the vendor or even the supply chain. The agent operates from inside the institution and can reach other third-party APIs the bank uses, expanding the risk surface and exposure considerably.
Speed. The time between dispatching a destructive action and that action becoming irreversible can be too quick for any human supervisor. The PocketOS incident took just nine seconds.
Suppose, for instance, that a bank’s agent, operating inside a third-party IDE, used an over-permissioned credential to alter a payments workflow, delete a risk-management database, or modify a sanctions-screening configuration. Under current TPRM guidance, examiners would focus on the vendor of the IDE. But doing so would not provide answers to the more important question: what authority did the agent actually have inside the bank’s operating environment?
Policymakers could attempt to respond to this by redrawing the bank regulatory perimeter or trying to scope in the whole supply chain into TPRM, but I’m not sure either would be wise or necessary.
Tiered autonomy
A better approach would be to focus on agentic systems (rather than vendors per se) and the controls needed for different levels of agent autonomy.
Fortunately, to do this bankers and supervisors do not need to start from scratch. They can leverage extensive research and standards related to autonomous driving, e.g., SAE J3016, which lays out the widely-referenced six levels of driving automation.
Focusing on the degree of agent autonomy, as opposed to vendor capabilities and dependencies, enables a sharper focus on relevant controls. The table below maps autonomous driving control concepts to agentic AI and banking.
This mapping provides the foundation for the prototype tiering in the next table on proposed autonomy levels for agents in banking.
Importantly, the Tier is not determined by whether a system is called a chatbot, copilot, coding agent, or workflow tool. It is determined by the system’s ability to initiate, execute, and complete actions that affect bank systems, customers, counterparties, controls, and regulatory obligations.
The key benefit of this approach is that the control requirements for each Tier are clear and intuitive. These are discussed in more detail in the attached memo.
Notably, this approach backtests well against the PocketOS incident. As noted in the memo:
The PocketOS deployment was perceived by its operator as a development-assistant workflow — Tier 3 with execution restricted to non-production. In operational reality, the deployment was Tier 4 or Tier 5 depending on the harness session configuration: the agent had access to a credential whose authority reached production, and the harness did not effectively mediate the credentialed external mutation. The divergence between perceived and actual tier is the central diagnostic. A supervised institution running an analogous deployment must classify on the actual tier — capability under foreseeable failure — and apply the supervisory expectations of that tier.
This framing should sound familiar to bankers and examiners: An institution was supposed to classify something as X, but instead classified it as Y, which led to a problem. Supervisors examining institutions for whether they are properly classifying things can help ensure those institutions are engaged in safe and sound practices.
To see how this could work in practice, below is a prototype “supplemental examiner aid” to guide examinations of agentic AI deployments using the tiered autonomy framework under TPRM.
To be clear, under this approach current TPRM would remain relevant for vendor governance, due diligence, contracts, monitoring, etc. Cybersecurity frameworks would remain relevant for credentials, logging, access controls, and incident response. Model risk management would remain relevant where model behavior affects decisions. And operational resilience would remain relevant for recovery, continuity, and impact tolerance. But none of these addresses delegated machine authority across systems, which is the essence of agents. The proposed examiner aid begins to tackle that.
Conclusion
The PocketOS incident was a nightmare for the CEO and the rental car companies that relied on it. But it also provided the public with a view into how an agentic AI deployment can go wrong.
It has given us all something to learn from. This post has focused on three lessons in particular:
The need for NTSB-style accident reports for agentic AI incidents.
Humility when orienting systems to face agents, instead of people.
The benefits of a tiered autonomy approach to agentic AI in the context of third party risk management expectations for banks.
The PocketOS incident revealed that agentic systems can expose latent weaknesses at machine speed. To build trust in agents there needs to be credible accident reporting, robust classification of actual autonomy, and well-designed controls for systems that act faster than people can supervise. That is the work AI builders, banks, and regulators should focus on now.
