Field note

Are you agent ready?

Every organisation can describe its human experience. Almost none can describe its agent experience: what software acting for a customer finds when it reads the site. We built a tool that shows you. Here is what it measures and how to read the result.

WHAT THE PERSON SEES WHAT THE AGENT SEES layout, a picture, colour, a button text, structure, an address it can write to
Fig. 30  /  The same page, read twiceOne source, two readers, nothing hidden

In August I argued in these pages that a second audience had arrived: software that reads, verifies and decides on a customer's behalf, and judges a business on terms its human customers never applied. The most common response was not disagreement. It was a question.

Fine. How do we know where we stand?

This note is the answer we built. It is a tool, it is free, and it takes about a minute.

IThe gap

The experience nobody designed

Don Norman has said he coined the term user experience at Apple in 1993 because the words then in use, human interface and usability, were too narrow for the work. The discipline that grew from it is now one of the best resourced functions in digital business: research teams, usability labs, design systems, experimentation platforms, and a head of experience on most leadership teams. Any serious organisation can tell you its conversion rate, where the journey leaks and what its customers said afterwards.

Ask the same leadership team what an agent experiences when it arrives at the site on a customer's behalf, and the room goes quiet. Not from complacency. Nobody has looked. There is no team, no metric and no dashboard, and the phrase agent experience is less than two years old.

The human experience has been designed on purpose for three decades. The agent experience is whatever is left over.

Left over is not nothing. It is the document the server sends, with the pictures, the scripts and the styling stripped away. Every website already has an agent experience. It has simply never been seen by the people who own the site, which makes it the one experience nobody designed.

You cannot design an experience you have never seen.

IIThe reader

How an agent reads a website

It helps to be literal about this, because most of the mystique around AI search and agentic commerce dissolves once you watch what the software actually does.

An agent working for a prospective customer does not open a browser. It fetches the page with a plain HTTP client. No JavaScript runs, no images load, no stylesheet applies. What arrives is the document the server sent, and if the words on the page are drawn later by a script, as far as this reader is concerned they were never there.

Before it reads anything it checks whether it is allowed in, and whether there is a map. Then it reads, and it pays for every token, so navigation, banners and boilerplate are a cost before they are a nuisance. It looks for structured data to work out who you are. Then it tries to answer the questions the person asked: what does this organisation do, who is it for, what does it cost, how do I buy or get in touch. And if the person wants to proceed, it looks for something it can act on: an address it can write to, a form it can submit, a link it can follow, an interface it can call.

robots.txtThe gate
A plain text file that says which visitors may read which paths. AI crawlers and agents identify themselves and honour it. Restricting the crawlers that gather training data is a considered choice. Blocking the agents that fetch on a customer's behalf is a closed door.
llms.txtThe index
A short markdown file at a fixed address: the site's name, a one-line summary and links to the pages that matter, each with a description. Proposed in September 2024, and the nearest thing agents have to a front door.
MarkdownThe cheap rendering
The same page without the chrome. Agents pay for every token they read, so a plain text version of a page is worth more to them than any layout. Served as a twin file beside the page, or negotiated by a request header that asks for text instead of HTML.
JSON-LDThe identity card
Structured data in the head of the page: who the organisation is, what it offers, how to reach it, in the shared vocabulary of schema.org. It is how an agent names and cites you correctly without reading everything.

A form drawn by a third-party script is, to this reader, a blank space. A price that lives only in a PDF is a price that does not exist. A beautiful page with the substance in an image is an empty page.

None of this is hidden. All of it is unfamiliar, because nobody on the human side of the screen has ever had to read a website this way.

So we built something that does, and writes down what it finds. agentready takes a web address and a kind of site. It fetches what an agent would fetch, in the order an agent would fetch it: the robots file, the sitemap, the index, the home page and a handful of linked pages, probing as it goes for markdown versions, structured data, forms and any documented interface. A model then reads the home page text alone and writes down what it takes the business to be, and what a prospective customer would still want to know. That paragraph sits at the top of the report. If it is wrong, every answer an agent gives about you is wrong in the same way, and that is worth knowing before anything else.

IIIThe rubric

Five things it measures

The rest of the report is twenty checks in five areas. Each check is a page of plain English that tells the assessor what to look for in the evidence and what a score from zero to four means. The model judges. The arithmetic is done in code. Choosing the kind of site changes the weights and switches off the checks that make no sense for it: a consulting firm is not marked down for lacking an API description, and a shop is not expected to publish its catalogue as a single text file.

  1. Discovery and accessWeight 20 Are agents allowed in, and can they find the pages that matter without guessing? The robots rules that apply to AI user agents, a sitemap, the llms.txt index and its full-text companion. If an agent cannot get in, nothing else on the site helps it.
  2. Content retrievabilityWeight 25 Does a plain fetch return the content? Words in the initial HTML, markdown alternates, the ratio of substance to chrome, and the headings and landmarks that let a reader find the point.
  3. Structured data and metadataWeight 15 Does the site say who it is in a form a machine can use? JSON-LD, Open Graph tags, page titles and descriptions, canonical addresses. This is how an agent cites you accurately.
  4. AnswerabilityWeight 25 Can an agent acting for a prospect answer the four questions from the content alone: what you do, who it is for, what it costs, how to buy or make contact? This is the area that matters most to a business, and for a services firm it carries the most weight. A site agents cannot answer from is a site agents will not recommend.
  5. Agent actionabilityWeight 15 Can an agent act, not just read? Public API documentation, an OpenAPI description, an MCP server, and machine-usable routes to the things people do through forms: enquire, book, buy.

Each area scores out of a hundred, and the areas combine by weight into one number. Seventy-five and above is strong, fifty is fair, twenty-five is weak, and below that is poor. The number is the least interesting thing on the page, for reasons I will come to.

IVThe example

We ran it on ourselves

It would be odd to publish a measuring stick without standing against it. On 20 October we scanned theoverstorygroup.com as a services site. The scan read the home page and three linked pages, made eighteen requests to the site and took twenty-four seconds.

Fig. 31  /  theoverstorygroup.com, 20 October 2026Overall 75 of 100. Strong, by one point

Seventy-five overall, which is strong by exactly one point. Four of the five areas sat between seventy-eight and eighty-five. We built this site with the second audience in mind, with a markdown twin for every page and an index for agents from the first day, so that much was expected.

The paragraph at the top of the report is the part worth reading twice.

What an agent takes us to be

Overstory Group is a professional advisory firm that works with boards, CEOs and executive teams on strategy, organisation design and capability relating to artificial intelligence. Based in Melbourne, Australia, the firm provides advisory services, coaching programs and thought leadership for sectors such as financial services, energy and utilities, telecommunications, government, professional services and private equity.

Not clear from the home page

The text does not state the pricing structure or the specific fees for advisory and coaching engagements.

Fig. 32  /  Read from the home pageThe assessor's own words, from the text of one page

It got us right, from the text of one page, with nothing else to go on. Where it marked us down is more useful than where it did not.

  1. What it costs. Pricing and terms scored one of four. The site says how to start a conversation and says nothing about how an engagement is priced. The assessor said the same thing in one line at the top of the report. For an advisory firm that is a choice, and a defensible one, but the tool turns a default into a decision. It is the fourth leadership question from the August essay: what are you willing to expose.
  2. Nothing an agent can act on. Agent actionability scored twenty-five. Our contact forms are drawn by a third-party script. A person sees a form. An agent sees the name of the script and a blank space. A plain email address and a booking link kept the score off the floor. We knew this. We had not weighed it.
  3. The things we built that nobody can find. Every page here has a markdown twin, and the scan found them, then marked us down because nothing advertises them: no link element in the head of the page, no content negotiation. The full-text file for agents exists and is not linked from the index that is supposed to point to it. Two lines of configuration, and I had not written them.

The gap between building for the second audience and being found by it is made of small things nobody owns.

Three items went on a list that afternoon. None of them needed a workshop. All of them needed someone to look.

VLeadership

What to do with the number

Treat the report the way you would treat a first usability test. It is not a verdict. It is the first time anyone has watched this customer try to use your site, and the useful output is a list, not a score.

  1. Read the paragraph first.

    If an agent reading your home page cannot say what you do and who it is for, nothing else on the report matters yet, and no amount of structured data will fix it. That is a writing problem, and the writing belongs to the leadership team.

  2. Sort the findings into two piles.

    Most are plumbing: dates in a sitemap, a link element, a schema type, a plain form behind the scripted one. A developer afternoon each, and they go to the web team this week. A few are decisions: whether to publish how you price, whether an agent may book a call on a customer's behalf, who owns the machine journey at all. Those do not go to the web team. They come to you.

  3. Run it again in a quarter.

    Then it is a trend, and a trend is something an executive team can own. The organisations that treat the second audience as a design constraint will have a number that moves. The ones that treat it as a channel will have a number.

Some honesty about the instrument. The assessor is a language model, and if you scan the same site twice a few checks will move by a point. It reads a handful of pages, not the estate. It measures whether you are legible to agents, not whether agents are in fact citing or choosing you, which needs measurement most organisations do not yet have. It is a reading, not an audit, and it is free because the conversation it starts is the point.

The human experience was designed on purpose, for thirty years.

The agent experience is happening anyway. The only question left is whether you have looked.

Enter your address, say what kind of site it is, and read what the agent reads.

You cannot design what you have not seen.
