|
| But it also gets to one of Claude's (Opus 4.5) current weaknesses

| Are you sure about that?
|
| Try "claude --chrome" with the CLI tool and watch what it does
| in the web browser.
|
| It takes screenshots all the time to feed back into the
| multimodal vision and help it navigate.
|
| It _can_ look at the HTML or the JavaScript but _Claude_ seems
| to find it "easier" to take a screenshot to find out what
| exactly is on the screen. Not parse the DOM.
|
