Dualmark CLI
dualmark · App
Dualmark CLI is a conformance test runner for the AEO Specification. Given a page URL, it checks that a markdown twin of the page is reachable, served as markdown with the expected headers and advertised from the HTML page, then tests whether requests from the GPTBot user agent or with a markdown Accept header receive markdown. It prints a score and level, can emit JSON, and exits with a non-zero code when the page falls below the passing threshold, so it can run in CI.

Why it's useful
Shows whether a page serves a markdown version to the GPTBot user agent and to clients that ask for markdown.
What you could do with it
- Run it against a blog post URL to see which markdown and header checks the page passes.
- Skip the content negotiation checks for a static site that serves markdown only at fixed addresses.
- Add it to a CI pipeline so the build fails when a page scores below the passing level.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
- Data handling disclosed
- finding
- no statement of what it reads, writes or sends (README.md)
Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.
In its maker's words
Conformance test runner for the AEO spec. `dualmark verify <url>` scores any site against the AEO Specification.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.11.0, the file with digest sha512-fnF/7AJ4XBemweTD4kzDunmIzaZ2aW+LQwTAQnet10V8104MnR9War1OucUeQ4dLbO6OC2bK+ysXys+Ingkz0w==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
Run it with:
npx -y @dualmark/cli@0.11.0Pinned to 0.11.0, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.
