The last piece of the operating layer is the one most people skip: accessibility. That means building so a person who cannot see well, or cannot use a mouse, can still use what you made. It is not charity and it is not red tape. It is reaching more customers. Today you learn how to let an agent find the barriers in your site that you walked right past.

Step one. Use an automated accessibility checker. The agent can run a tool like axe against your live page through a headless browser and get back a plain list of problems: this image has no description, this text is too faint to read, this form field has no label. You stop guessing what might be wrong. The tool hands you the actual list, ranked by how much it hurts.

Step two. Every image needs alt text, a short written description a screen reader speaks aloud for someone who cannot see it. Writing it for a hundred images is a dull afternoon. Hand the images to the agent and let it write the descriptions, then you read and fix the few it got wrong. The big T-M does this on every asset, because an image with no words is just a blank to a blind visitor.

Step three. Faint gray text on a white page looks clean to a designer and is invisible to a lot of real eyes. There is a measured rule for this called contrast ratio. Tell the agent to check every text color against its background and flag any pair that fails the rule. It does the math on every combination at once, which no one is going to do by hand.

Step four. Many people never touch a mouse. Have the agent drive your site using only the keyboard, tabbing through every button and link, and report anything it cannot reach or any place the focus disappears. If the agent gets stuck, a real person would too. This catches the trap doors, the menus and pop-ups that quietly lock out anyone who navigates by key.

Step five. Tell the agent to read your page in the order a screen reader would, top to bottom, by the underlying structure. If the order is a jumble, the page makes no sense out loud even when it looks fine on screen. Fixing the structure so it reads in a sensible order is the move that turns a page from technically allowed into actually usable.

Our honest proof: we run these same checks on our own pages, the audit, the alt text, the contrast math, the keyboard pass, the read-aloud order. No claim about how many people it reached, just the plain practice of testing the way real visitors actually arrive, including the ones most sites quietly leave out.

So accessibility is a set of checks, not a debate. Run an audit. Let the model write your alt text. Check the contrast. Drive the site by keyboard. Read it aloud in order. Pick one page and run all five today. The fewer people you lock out, the more you get to serve. See how we check ours at office dot temerarii dot xyz.
