Write alt text that conveys an image's purpose, marks decorative images empty, and handles functional and complex images. Use when adding images to content or auditing alt text.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Alt text writing
Alt text is what a screen reader speaks in place of an image, and what
shows when an image fails to load. Good alt text conveys the image's
*purpose in context*, not a literal description; the most common
mistakes are missing alt, useless alt ("image"), and describing
decorative images that should be silent.
## Method
1. **Convey purpose in context, not literal description.**
The same image needs different alt text depending on why
it is there: a photo of a person might be "Dr. Jane Smith"
in a bio, "Team member smiling" in a culture page, or
nothing if purely decorative. Ask "what does this image
communicate here, and what would a sighted user take from
it?": that meaning is the alt text, not an inventory of
pixels.
2. **Mark decorative images empty.** Images that add no
information (backgrounds, dividers, decorative flourishes,
an icon next to text that already says the same thing)
get `alt=""` (empty, not missing): so the screen reader
skips them entirely. Decorative images with descriptive
alt, or with no alt attribute at all (screen readers then
read the filename: "IMG_4021.jpg"), are noise that

How to install
mdr add amey-thakur/ai-skills/alt-text-writing@sha256:0b0c20e38f9edf06The line at the top of this page pins the label git:20260728.fac4544, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
