Five synthetic readers of release candidate 2

Five invented readers, two from Generation Z, two from Generation X and one publisher, read release candidate 2 from the first page the way each would, said where they would put it down and whether they would buy it there, then finished it as beta readers and were interviewed. Nobody would buy it as it stands. Four of the five would buy it, or commission it, once the chapters that form the company are written; the fifth, the sceptic, would not buy it in any form he was offered, and still rated it 3 out of 5.

Everybody in this study is invented. The readers, their names and every word attributed to them were written by a language model (Claude Sonnet, one agent per reader) reading the candidate's text. It is not reader research, and no sentence in it is evidence about a real person or a real market. What is evidence is the candidate's own text: every quote a reader cites is checked by the build, word for word, against the unit it cites, in the frozen file whose hash is recorded here. Candidate v2.0.0-rc2, sha256 5ed445042a0b5499…, read on 2026-10-19.

The protocol · every finding · the interviews, question by question · the brief

Will they buy it?

Not this candidate. Where they put it down, Aisha said no, Ellie and Nadia said maybe, Martin said no, and Catherine, the publisher, said she would commission it with conditions. After reading the whole book: four maybes and one no. The ratings are 2, 3, 3, 3 and 3.

One reason, from all five. The book promises on its first pages that by the end you will have started a company, and the two chapters that say how, The company itself (22) and Form your company (37), are placeholders. Every reader who came for the company went looking for those chapters; Nadia put the book down at 37 and Aisha just after it, and Ellie, who came to build, put it down at the weekend chapter that follows. Aisha, Ellie and Nadia all went to Start the company or Hands on out of order, from the contents page; nobody but Nadia read the book in order past part 2. This gap is already known: it waits on Dinis's memos (the UK, Lithuania, Portugal, the EU). The study's contribution is to show that it is not one gap among six but the one that decides the sale.

Would they see the value? Yes, in specific chapters, and the same ones come up again and again: Everyone who can brief an agent is a developer (8), Explorer coding (9), Your first workspace (13), the miss-it test and the card-fee arithmetic in Ship it and Price it (18, 19), Fund it, or do not (21) and the reach, mandate and gap model in Controlling your agent (25). All five would send something on to somebody, and every one of them named chapters, not the book. That is the shape of the problem: a good book of about 50,000 words inside a 75,000-word manuscript.

What stands between them and the purchase, after the company chapters: the hands-on part repeats the argument chapters it follows (measured: 29% of chapter 13 is in chapter 30, 15% of chapter 19 in chapter 39); there is a long road to the first thing to do (8,751 words of part 1 after chapter 1, and the first afternoon of work about 26,000 words in); the worked examples are usually the author's own products; the technical chapters lose the non-coder the frame says is a developer; and the co-writing with Claude is said only in the last chapter.

The pacing, from the readers' own marks (the grid below): all five marked chapters 2 and 5 and the making-of (41) too slow, and four marked 39, the repeat of 19. The highest interest is in chapters 1 and 15 (4.0), then 8, 13, 17, 18 and 38 (3.8); the lowest in the two placeholders (22 at 1.4, 37 at 1.2), the storyboards chapter (34) and the long game (part 8, 2.3 on average). By part, Direction and judgement, Working with agents and The frame hold readers best (3.4 to 3.6); Before you start (2.8), Getting the job (2.6) and Hands on (2.7) least. The book is slowest exactly where a reader decides whether to keep going.

The publisher's verdict: commission, with conditions. The hook (two generations, start a company, Gen ZX) and the expert founder as the reader are worth it. The conditions: the company chapters written; one lead reader; 20 to 25% cut by merging duplicates and moving the process to an appendix; the dated tables on a web page; the products disclosed as case studies; a legal read of the funding and tax passages; and the free first edition and free online edition settled in the contract.

What we expected, and what happened

Reader Expected, before the run What happened
Aisha (Gen Z, on a phone) Puts it down in part 1 or 2; no Skimmed to chapter 2, then jumped from the contents to Start the company and put it down at 39, a repeat of 19, after finding 22 and 37 empty. No, then maybe. The jump was not expected, and it is the pattern of the study.
Ellie (Gen Z, never coded) Puts it down in the frame or the build part; maybe Read 8 and 13 (interest 5 each), then put it down at 40, the weekend chapter, on its jargon. Maybe. As expected on the jargon; she got further than expected because chapter 8 held her.
Nadia (Gen X, the expert founder) No put-down, or at 22; yes if the company chapters were filled Read in order to 22, skipped the job chapters, put it down at 37 after finding 22 empty too. Maybe, the paperback at £19.99 once written. As expected; not expected: her first question was money, how a person with a mortgage survives leaving a salary, which the book never mentions.
Martin (Gen X, the sceptic) Puts it down mid build part; no Hunted (1, 2, 17, 24, 25, 16, 21, 41); no. As expected on repetition and products; not expected: he rated it 3, credits the honesty, and names 21 and 25 as ideas he would use tomorrow.
Catherine (publisher) Commission with conditions Commission with conditions, as expected, and the conditions match. Not expected: the late co-writing disclosure, the image rights and named people to clear, and her title advice, to drop Generation Z Developers from the front.

What would make it better, by what it costs

Marked for Dinis: a decision only Dinis can take, or material only he can supply. The rest is the editor’s to propose to the board.

  1. loses the sale for Dinis Write chapters 22 and 37, at least for the UK: the registration, the bank account, what it costs, in steps, from Dinis's own experience; or, until they are written, take the promise of a registered company off the first pages.
    All five name it, and it is the reason the three readers who came for the company did not buy. It waits on Dinis's memos: the gap articles of the Gen ZX brief. From aisha-1, catherine-1, catherine-2, ellie-1, martin-1, nadia-1.
  2. loses the sale for Dinis Answer the person leaving a salary: how long to keep the job, what savings to put in, what the first three months cost, using the expert founders the book already names.
    The frame's primary reader asked this first, and the book never mentions runway, salary, savings or a mortgage. One reader, but the one the frame is written for. From nadia-2.
  3. loses the reader Merge the hands-on chapters into the argument chapters they repeat, or cut the repetition from one side: 13 and 30, 19 and 39, 7 with 32 and 33, 12 and 36, 16 and 35. Put the exercise beside the idea it practises.
    Five of five noticed, and two stopped trusting the length because of it. Measured: up to 29% of a chapter is restated word for word. From aisha-2, catherine-3, ellie-5, martin-2, nadia-6.
  4. loses the reader Get the reader doing something within fifty pages: open chapter 1 with the promise and the first step, shrink chapters 2 to 5 (8,751 words) to one or two, and bring the first workspace afternoon (13) forward, to just after 8.
    Aisha, Ellie and Nadia skimmed or skipped most of part 1; Aisha and Nadia name it as where the book was slowest. From aisha-3, aisha-6, aisha-7, ellie-7, nadia-3.
  5. loses the reader Give the non-coder a path through part 7 and the weekend chapter: define each term at first use (serverless, Worker, R2, Durable Object, repository, fork, vault), and a no-code route to a page a stranger can use in chapter 40.
    Chapter 8 tells the non-coder she is a developer, and she believed it (interest 5); chapter 40 is where she put the book down. From ellie-2, ellie-3, nadia-4.
  6. costs trust Use at least one worked example per founder chapter that is not the author's product (an insurance tool, a clinic, a dog groomer's diary), and label the product chapters (24, 25) as case studies of the author's own companies.
    Five of five raised it. The check says 'always' is too strong but 'usually' holds; the disclosure helps, and readers still could not tell advice from a pitch. From aisha-4, aisha-5, catherine-4, ellie-4, martin-3, nadia-5.
  7. costs trust for Dinis Say that the book is co-written with Claude at the front, not only in chapter 41, and move how it was made (the about note and chapter 41) to one short appendix, keeping the measure and the invitation to tell us about your company.
    The brief behind the book says to meet the suspicion of AI slop head on; four of five readers said it reads mostly as a person and named the same machine marks (the repeated openings, the near-copied chapters), and the publisher says the disclosure comes 40 chapters late. From catherine-5, martin-6.
  8. worth fixing Make a reader's edition of each candidate without the For Dinis notes, for the next study and for any reader outside the team, and replace the opening of chapter 2, which rests on an essay the author could not read.
    The notes are right in a candidate (decision 009), and every reader still read through 47 of them; the paywalled essay was the first claim two readers did not believe. From catherine-6, ellie-6, martin-7, nadia-7.
  9. costs trust In Fund it, or do not, add a section for the founder with no revenue yet, and let the worked example be one of several.
    The worked example is a £10 million company; the expert founder at the start has no use for it yet, and the sceptic found the close more confident than the evidence. From martin-4, nadia-8.
  10. worth fixing for Dinis Decide the length: the publisher and the sceptic would cut towards 50,000 to 60,000 words; decision 012 says 200 pages or more. Merging the duplicates (r3) alone removes several thousand words without losing an idea.
    The first edition was liked for being short and punchy, which the brief behind this edition says it must be again. From martin-2, catherine-3.
  11. worth fixing for Dinis Decide whether the book leads with one reader. The publisher would lead with the expert founder and move the job chapters (10 to 12) to a companion; Nadia skipped them; Aisha, the Gen Z reader, skipped them too and went to the company part.
    Decision 015 makes it a book for two generations; the readers suggest the two meet in the company part, not in the job part. From the interviews.
  12. worth fixing for Dinis Move the dated tables (programmes, credits, prices) to a web page refreshed each year, with the book pointing at it; keep the argument in print.
    The publisher's condition. Decision 013 already dates the hands-on part; this is about where the dated part lives. From catherine-7.

How it was run, and what went wrong

Run on 19 October 2026, five Claude Sonnet agents in parallel, each given its persona, the protocol and the candidate split into its 52 units with the contents page, and nothing else. The runs took three to five minutes each. All five records passed the build's checks first time or after correcting quotes, and every quote on these pages is word for word in the unit it cites.

What went wrong, kept rather than hidden. Ellie's agent said that in the asked phase it read only the opening and the headings of the chapters she had not opened, not the whole text, so her asked-phase steps are lighter than the protocol says; her natural phase, where her put-down point and decision come from, was read in full. Nadia's agent filled the read and thought fields of skipped steps with "Not opened", because the build asks for them on every step; the next version of the protocol should not ask for them on a skip. Ellie's agent wrote its record with a script, which is allowed; the record is what is checked.

What the method cannot tell. These are invented readers played by one model family, reading a manuscript with notes in it. They agree with each other more than five real people would. The numbers (put-down points, ratings) are the model's, not a market's. What is evidence is the text: the quotes, the measured repetition, the searched absences.

Next time. A reader's edition without the For Dinis notes (r8); the same five on rc3, so a finding that disappears is a fix that worked; one reader outside both generations (a millennial, the reader the book says is not its first) to test what decision 015 leaves out.
