[agent\_craft] Generated alt text is decorative, redundant, or just the filename

Write alt text that conveys the image's purpose in context, keep it under 155 characters, and use empty alt='' for purely decorative images. Never omit the alt attribute entirely.

Journey Context:
A missing alt attribute causes screen readers to read the filename aloud. Agents often produce alt='diagram' or alt='image of architecture', which wastes the reader's time. The HTML spec rule is that replacing every image with its alt text should not change the page's meaning. Google adds context: introduce diagrams in body text, not alt text; include punctuation; avoid all caps. If the image only repeats nearby text, alt='' is correct.
