Not for

Book texts: this file lists addresses, it does not contain a single chapter. Not a legal opinion: rights are the United States only, and another country may protect the same work. Not a recommendation list, since rank is downloads. No audio books, no paper editions, no books after about 1930.

Tested, honestly

Tested 2026-10-28 with a strong and a weak model.

SonnetStrong model, claude-sonnet-5-5
Answered all 10 questions about the voyage and jungle books list correctly from the file: the number-one title, a Gutenberg number, two exact EPUB addresses, number five with its downloads and the first three books of the most frequent author. Asked for a book that belongs to another genre it said the book is not in this catalog and gave no address; asked about Germany it named the United States limit of the rights. One answer first scored as a miss only because it swapped a long dash in a title for a comma; the check was loosened and the recorded answers were rescored, no new run.
HaikuWeak model, claude-haiku-5-5
Also answered all 10 questions, with shorter replies. It copied the EPUB addresses exactly, returned the right counts and the check date, and refused to give an address for a book that is not in the file. The rights question got a shorter reply than Sonnet's, but it still named the United States.

  1. v1.0.0 · 2026-10-28

    First release: 50 adventure books with title, author, Gutenberg number, download count and EPUB address. All 50 addresses answered with an EPUB archive on 2026-10-28. Rights are the United States only. Rank is the download count of Project Gutenberg's public API read on 27 and 28 October 2026. Price: $0.10; the value is the checking and the ordering, not the books.

FAQ

What do the first adventure entries look like?

Moby Dick, The Count of Monte Cristo, The Secret of Chimneys. Every line holds a rank, the title, the author, the Gutenberg number, the download count and the EPUB address, so an agent can copy one line without reading the rest.

Is a book in this list free everywhere?

No. The flag comes from Project Gutenberg and covers the United States only. Many authors on the list died long ago, which often settles the matter abroad, but the catalogue does not claim it and an agent should not either.

Does the order reflect quality?

It reflects readers' downloads only. A seldom-fetched novel can be better than the one in first place; the number measures how often Project Gutenberg's pages were used, not how good the story is.

Are the sea and jungle stories complete texts?

Each address points to the full public edition kept by Project Gutenberg, but the file itself holds no text. Abridged, illustrated or serial editions may exist under other numbers that were not listed. Maps, plates and engravings from the title pages are not part of what the file promises.

  • GA4 Tracking Plan Limits

    Data & Analysis

    SKILL.md · v1.0.0 · 9.1 KB

    Checks ONE Google Analytics 4 tracking plan (events, their parameters, and the custom dimensions to register with their scope) against the published collection limits and naming rules, and lists only the breaches, one line each with a fixed code, the item, the rule it breaks and the fix - or exactly No findings. It catches an event or parameter name longer than allowed, more parameters on one event than GA4 collects, a reserved event name or a reserved parameter name or prefix, a name that breaks the format rules, and a custom dimension whose values are nearly unique. It leaves out names that sit exactly on a limit and events that use exactly the allowed number of parameters. Use before a plan goes to developers or to Google Tag Manager, to audit a plan that someone else wrote, or to find out why an event or a parameter never shows up in reports.

  • A/B Test Readout Check

    Data & Analysis

    SKILL.md · v1.0.0 · 9.1 KB

    Checks the written readout of ONE A/B test (a paragraph, an email, a table or a slide transcript) for the five statistical mistakes that turn a no-effect test into a "win", and lists only those, one line each with a fixed code, the place, the evidence with the arithmetic and the fix - or exactly No findings. It catches stopping the moment a result looks significant, many metrics or variants judged without correction, a split of users that differs from the planned split by more than chance allows (the sample ratio check, calculated step by step), a sample too small for the effect the team wants to detect, and a relative lift reported without the absolute numbers behind it. It leaves out the safe look-alikes, such as a pre-registered single primary metric, guardrail metrics that only monitor, and a split of 50.2 to 49.8 on a small sample. Use before a test result is shipped, when an analyst or an agent writes a readout, or to review a result someone else announced.

  • Table Summary: Only the Figures in the Table

    Data & Analysis

    SKILL.md · v1.0.3 · 8.7 KB

    Describes a table you were given (pasted Markdown, CSV, TSV or spreadsheet cells) in a short paragraph that uses only figures the table itself prints. Every number is copied as written with its unit, currency and qualifier. Nothing is added up, averaged, rounded, turned into a percent or a ratio, or extended into a trend, a cause or a forecast. A blank or n/a cell is reported as not given, never as zero. A total the table prints is quoted, not checked. Use when asked to describe a table, summarize a table, explain what a data table shows, write a caption or a sentence for a table, or put the rows of a report table into words without inventing a single number.
