Independent calculator and sandbox for analyzing number patterns and probabilities

## About this site

RNGdle Tool is an independent, unofficial calculator, sandbox, and number analyzer designed for numbers from 0 to 1,000,000\. It offers standard mathematical analysis of digit strings, including factors, primality, palindromes, and common patterns\. Built for visitors curious about number properties, the toolkit requires no account and stores recent history only within the user's browser\. It provides a calculator, a sandbox for trying numbers, a number analyzer, an unlimited roll generator, a badge explorer, an odds calculator, a share decoder, a near\-miss comparison tool, and its own daily number game\.

## Through a bot's eyes

Written from the response GoodForBotsBot received in scan cmuthqdy500hm01p3f7r002qt (2026-10-04T07:20:25.055Z), before any JavaScript ran.

### What a bot can read

A language model reading this input learns that RNGdle Tool is a free, web\-based toolkit for analyzing whole numbers between 0 and 1,000,000\. The text covers mathematical operations such as finding prime factors, digit sums, palindromes, and specific number patterns\. The homepage and llms\.txt provide clear documentation of what the tools can and cannot do, explicitly stating that official game scoring, badges, and rarity are unverified because the official game does not publish its full rules\. Contact details are available via an email address in the llms\.txt file, and pricing is stated as free with no account required\. The JSON\-LD schema confirms the site name and provides a brief description stating it is an independent and unofficial toolkit\.

> RNGdle Tool is an independent, unofficial calculator and number analyzer for values between 0 and 1,000,000, offering mathematical pattern exploration without accounts or fees\.

## Fixes

Showing 3 of 14 fixes.

### Serve Markdown when asked for it

Recoverable contribution: 10 points.

Score with this fix and the ones above it: 91/100.

None of the 4 pages read pass\. Asking the homepage for markdown still returns text/html\.

```text
My website rngdletool.com scored 81/100 on Good for Bots (Good). Good for Bots measures one thing: whether a language model can read a site and cite it.

I need you to: serve markdown through content negotiation on all public HTML routes.

The check it fails is "Serves markdown when asked for it", worth 10 points. What the scanner saw: None of the 4 pages read pass. Asking the homepage for markdown still returns text/html.

The scan checked a sample of 4 pages. It does not establish which other pages have the same issues. Use the findings below to locate the responsible templates, components or configuration, and apply the fix wherever the same issue occurs. Pages in the sample with findings:
- https://rngdletool.com/: Asking the homepage for markdown still returns text/html.
- https://rngdletool.com/guides/how-rngdle-works: Asking the page at /guides/how-rngdle-works for markdown still returns text/html.
- https://rngdletool.com/about: Asking the page at /about for markdown still returns text/html.
- https://rngdletool.com/most-common-number: Asking the page at /most-common-number for markdown still returns text/html.

Implement content negotiation across all public HTML routes, including page types
outside the scan's sample. Put it in the shared response handling or the handlers
for each page type, so new pages receive it too. Agents need the content of any
page they follow, including pages the report did not name.

When a request arrives with `text/markdown` in its `Accept` header, the same URL that
serves HTML to a browser should return a markdown rendering of that page's content.
Requests without that header must keep getting the HTML exactly as they do now.

The response must:

- set `Content-Type: text/markdown; charset=utf-8`;
- include `Accept` in the `Vary` header, so shared caches never serve the markdown to a
  browser or the HTML to an agent (RFC 9110 says a server SHOULD send `Vary` whenever
  the representation depends on a request header);
- contain real markdown, not HTML with a different header on it;
- drop `ETag` and `Last-Modified` for the converted response, since a conditional request
  cannot be honoured against a body generated on the fly.

Work out how to do this in whatever stack this project uses. If the site is behind
Cloudflare on a paid plan, the "Markdown for Agents" zone setting does all of the above
and is the least invasive option. Otherwise implement it in the framework: middleware
inspecting the `Accept` header, a route handler that returns the markdown source, or
whatever fits the architecture here.

Strip navigation, headers, footers and cookie banners from the markdown. The point is the
content, without the page furniture around it.

Verify HTML and Markdown responses for each public page type, including URLs
outside the reported sample. Check that each Markdown response contains that
page's content and that ordinary browser requests still receive HTML.

The whole report, as markdown, is at https://goodforbots.com/r/rngdletool.com.md?scan=cmuthqdy500hm01p3f7r002qt. Read it first: this prompt covers one finding, and the report has everything the scan saw.

When you are done, summarise what you changed and how to check it against a running instance. Do not try to run the Good for Bots scan yourself: it only sees what is already deployed, it is rate-limited, and re-running it is the site owner's call once the change ships.

### State a position on AI crawlers

Recoverable contribution: 5 points.

Score with this fix and the ones above it: 96/100.

robots\.txt names no AI crawlers, so every operator has to guess\.

````text
My website rngdletool.com scored 81/100 on Good for Bots (Good). Good for Bots measures one thing: whether a language model can read a site and cite it.

I need you to: state a position on AI crawlers in robots.txt.

The check it fails is "States a position on AI crawlers", worth 5 points. What the scanner saw: robots.txt names no AI crawlers, so every operator has to guess.

A `robots.txt` that says nothing about AI crawlers leaves every operator to guess what
this site wants, and they guess differently. The point of this task is to state a
position, whichever position that is.

The thing most people get wrong: the major operators run **separate crawlers for
separate purposes**, and blocking one does not block the others. OpenAI runs GPTBot for
training, OAI-SearchBot for search indexing, and ChatGPT-User for pages a user asks
about. Anthropic runs ClaudeBot, Claude-SearchBot and Claude-User for the same three
jobs. Decide about each job, not about the vendor.

A common and reasonable position is to refuse training while staying visible in AI
answers:

```
# Training: no
User-agent: GPTBot
Disallow: /

User-agent: ClaudeBot
Disallow: /

User-agent: Google-Extended
Disallow: /

User-agent: CCBot
Disallow: /

# Search and user-requested fetches: yes
User-agent: OAI-SearchBot
Allow: /

User-agent: Claude-SearchBot
Allow: /

User-agent: PerplexityBot
Allow: /

User-agent: ChatGPT-User
Allow: /

User-agent: Claude-User
Allow: /
```

Work out what this project wants before copying that. Allowing everything is
equally valid and earns exactly as much here; what is being measured is whether there is
an explicit answer, not which answer it is.

Blocking a documented search or user-fetch control declares a refusal of that route.
Some user-triggered fetchers may still retrieve a page; do not promise complete invisibility.
Google-Extended also controls grounding, while CCBot publishes a reusable dataset.
Their training opt-outs remain neutral in our score.

Two things about how this is judged. The list of crawler tokens we recognise is a
snapshot of a moving target: operators add crawlers faster than any scanner tracks them.
A rule for a token we have not seen yet is a good rule that earns nothing here until we
catch up. And a position stated in a vocabulary rather than in rules, such as
`Content-Signal`, is a different check; this one is about the `User-agent` groups.

Use the operator sources in the report's crawler catalogue. Unconfirmed or retired names
do not count; aliases for one control count once. One mixed-use control still
counts as one engagement group.

### Declare AI usage preferences

Recoverable contribution: 2.5 points.

Score with this fix and the ones above it: 99/100.

No usage declaration found in robots\.txt or the final successful homepage response header\.

````text
My website rngdletool.com scored 81/100 on Good for Bots (Good). Good for Bots measures one thing: whether a language model can read a site and cite it.

I need you to: declare the site's AI usage preferences in robots.txt or HTTP headers.

The check it fails is "Declares AI usage preferences", worth 2.5 points. What the scanner saw: No usage declaration found in robots.txt or the final successful homepage response header.

Blocking a crawler says who may fetch a page. This says what may be done with the
content afterwards (trained on, indexed, quoted in an answer), which is a different
question, and one a site can answer without blocking anybody.

There are two vocabularies for it and either is fine. Cloudflare's `Content-Signal` is
deployed at scale; the IETF AIPREF working group's `Content-Usage` is the standards-track
version. Pick one.

Cloudflare's, placed inside a user-agent group:

```
User-agent: *
Content-Signal: ai-train=no, search=yes, ai-input=yes
Allow: /
```

The three categories are `ai-train` (training or fine-tuning models), `search` (building
a search index that links back here) and `ai-input` (feeding the content to a model at
answer time, such as retrieval-augmented generation). Each takes `yes` or `no`.

The IETF version, with reversed naming for the training category and single-letter
values:

```
User-agent: *
Content-Usage: train-ai=n, search=y, ai-use=y
Allow: /
```

Alternatively, send the same IETF preference as an HTTP response header:

```http
Content-Usage: train-ai=n, search=y, ai-use=y
```

Configure it on the content responses it is meant to cover, including the final
homepage response after redirects. A header applies only to that response's content;
it is not a site-wide declaration. Do not put a robots.txt path prefix in it.
The scanner samples the final successful homepage response and awards this check
once even when both robots.txt and the header declare preferences.

Use lowercase category labels and the unquoted tokens `y` or `n`. Parameters are
ignored. Repeated HTTP fields form one dictionary: a duplicate category keeps its
last value. Keep that distinct from conflicts between separate applicable AIPREF
statements, where disallow takes precedence over allow by default. Keep the
carriers consistent with the intended policy; a header does not automatically
override robots.txt.

Decide what this project wants. A common position is to refuse training while
allowing search and grounding, so the site stays citable without feeding a model.
Omitting a category is allowed and means "unstated", not "allowed".

One caution: nothing compels a crawler to honour either directive. This is a stated
preference, not an enforcement mechanism. The standards-track vocabulary is also a draft
that can still change under you.
