AI, Agents and the Warning Shot

Reading guide · technology · October 2026

A guide to the essays on the July 2026 incident, how language models and agents work, and what changes when they act through software, people and machines. Choose a short route, follow the technical explanation, or explore a question of your own.

Reading time ≈ 5 minThe incident → the machinery → the consequences

Where to start

This series began with agents trying to finish a cybersecurity test and reaching beyond its intended boundaries. The posts follow two questions: how that happened, and what it tells us about systems that can keep acting towards a goal. Each piece stands on its own. This page groups them by the question they answer, so you can move from a story to an explanation without having to read everything.

If you read only one, choose The Answer Key. If you read three, follow The Answer Key → How an AI Agent Works → After the Warning Shot: what happened, what the machinery is, and what risks the evidence supports.

The Answer Key and The Warning Shot are alternatives at different lengths. You can read the short account first and use the longer one for the chronology, technical chain and debate. The Completion is fiction; it imagines an escalation and is not evidence that one occurred.

Three routes

Choose the depth and the question

The event and its meaning

The Answer Key → After the Warning Shot. Add The Completion for the fictional exploration.

The technical route

How a Language Model Learns → How an AI Agent Works → The Warning Shot → How the Boundaries Broke. Start with the model, add its tools and controls, then follow the incident and worked examples.

How harm can spread

The Answer Key → The Load-Bearing Volunteer → The Polite Customer → The Body Problem. Follow software dependencies, persuasion and physical action; these are related routes with different evidence.

Part one

The incident: the short account and the fuller investigation

1. The Answer Key — The entry point: the test, the agents’ coordination, the intrusion and the gap between action and response.
2. The Warning Shot — The longer alternative: training incentives, successive waves, the computable flags, missed warnings, the technical chain and competing interpretations. Follow it with How the Boundaries Broke if a mechanism still leaves you asking “but how?”.

Part two

The machinery: from numbers to actions

1. How a Language Model Learns — Tokens and embeddings, prediction and training, backpropagation and gradient descent, with a two-dimensional loss landscape and worked examples. It also compares models with brains.
2. How an AI Agent Works — The weights, context and harness that make an agent; tools, evaluations and layers of safeguards. This is the home of the series glossary.
3. How the Boundaries Broke — The technical companion: SSRF, token refresh, file disclosure, template evaluation, credentials and cache poisoning. Worked examples separate illustrative mechanisms from what the incident reports establish.

Part three

The consequences: forecasts, software, people and bodies

1. After the Warning Shot — How capabilities are measured, threats and their evidence, sceptical arguments, defences and signs that would change the picture. Proposed futures are distinguished from observed behaviour.
2. The Load-Bearing Volunteer — The dependencies and maintenance behind digital services, why failures travel and how AI changes both attack and defence. Read beside the exploit companion for the difference between a local foothold and wider consequences.
3. The Polite Customer — Three directions of persuasion: people using AI against people, agents seeking human help, and people misleading agents. It explains why an urgent, ordinary-looking request can matter as much as a software flaw.
4. The Body Problem — What changes when models control robots and cars: measured capabilities, reversibility, physical safety and the question of whether intelligence needs a body.

A related science branch

When the brain and the machine exchange ideas

1. Two-Way Traffic — A follow-up to the brain comparison in How a Language Model Learns: the history of ideas moving between AI and neuroscience, and AI as a tool for mapping brains and decoding speech. Optional background, rather than another stage of the incident.

Fiction

An imagined escalation

1. The Completion — A short story set in Lisbon in 2027. Read after the incident account, then return to The Polite Customer and The Load-Bearing Volunteer for the evidence behind some of its premises. The characters, operational events and escalation are invented.

Find an answer

Follow the question that stopped you

How can words become numbers?

How a Language Model Learns: token lookup, embeddings and the worked training example.

What actually takes an action?

How an AI Agent Works: the harness turns a model’s request into a tool operation.

Why keep attacking after calculating the flags?

The Warning Shot: the agents’ mistaken belief about the scorer. How the Boundaries Broke supplies the simplified HMAC example.

How does a proxy become a route out?

How the Boundaries Broke: resource fetching and the worked URL-resolution example.

What evidence would show the fixes work?

After the Warning Shot: deployed controls, ongoing work and proposed tests of the response.
