How the composite score works
The overall score is a weighted average: Visual 18.75%, Accessibility 25%, Buttons and links 31.25%, Under the hood 12.5%, and Mobile 12.5%. Unassessed categories are excluded and the remaining weights are normalized.
Product categories start at 100. Each distinct verified finding deducts 30 points for a serious issue, including a reproduced flow defect or material pricing contradiction, or 18 for critical, 12 for high, 7 for medium, and 3 for low stored detector severity. Scores stop at zero and round to whole numbers. All verified findings count, including those beyond the displayed list. The formula is fixed and versioned, so the same saved evidence always receives the same score.
The agent prompt is cut off at the right edge on phones
On the home page's Get started section at phone width, the agent prompt code block does not wrap. Its second line stops at "the solar systen" with the last letter cut at the right edge. Phone visitors who want to know what the prompt asks their agent to build have to scroll inside the block to read the rest.
Try it: Open / at 390px wide and scroll to Get started. The second line of the agent prompt block runs past the right edge.
Keyboard users lose their place before they can act
On the home page at phone width, the secondary navigation links "Get started" and "From Python to MP4" can take keyboard focus while the badge images in the article paint on top of them at every point tested. A keyboard user tabbing through the page cannot see where focus is while it moves through these links.
Try it: Open / at 390px width, click into the page and press Tab until focus reaches the table-of-contents links. The focus ring does not appear because the badge images cover it.
Keyboard users lose their place before they can act
On /changelog/ at phone width, the secondary navigation links "Unreleased" and "Changed" can take keyboard focus, but at every sampled point inside them the article's list items paint on top. Nobody can see where focus is while tabbing through that part of the page.
Try it: Open /changelog/ at 390px width, press Tab until the contents links get focus, and check that no focus ring appears.
The home page has no Open Graph or Twitter card tags
The head of the home page at / has no og:title, og:description, og:image or twitter:card tags. It does have a title ("Welcome - ManimGX"), a meta description and a working favicon. Links to the project shared on social platforms or chat apps fall back to a generic preview with no image.
Try it: View the source of https://manimgx.academa.ai/ and search for "og:" and "twitter:card". Neither appears.
The home page HSTS max-age is short and CORP is missing
The response from https://manimgx.academa.ai/ is missing Cross-Origin-Resource-Policy. HSTS max-age is 15552000.
Try it: Run curl -sI https://manimgx.academa.ai/ and read the Strict-Transport-Security value. Then check that no Cross-Origin-Resource-Policy header is present.
Screen reader users have to guess before taking the next step
Two `<button class="r">` elements inside the 12th child block have no text, aria-label, aria-labelledby or title. A screen reader user meets these buttons with no clue what they do.
Try it: Open / in Chrome DevTools, search the Elements panel for `button.r`, and check that the buttons have no text and no aria-label.
A rough edge in the layout
The expand chevron on the source file disclosure row sits about 30px above the vertical center of the filename label it belongs to.
A rough edge in the layout
The Pythagoras card description wraps in the middle of its equation, so the last term sits alone on the second line apart from the rest of the formula.
