Use when the user shares an image, chart, diagram, screenshot, or figure and needs it described — for alt-text, accessibility, documentation, or to understand what it depicts.
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 ## When to Use - User attaches an image and asks for a description or alt-text - User shares a chart, diagram, schematic, or screenshot and wants it explained - User needs an accessible description for documentation or publishing If the image is not attached, ask the user to attach it before proceeding. ## Invocation Notice - Tell the user when this skill is running: `alt-text`. Skip the notice when the user asked for the skill by name or slash command; spelling and spacing need not match. A phrase from this skill's own trigger list is not a name — naming the work is not naming the skill. ## Instructions Describe the figure so a reader who cannot see it understands both what it depicts and what it communicates. The description should be detailed enough that someone could reproduce or redraw the figure from the text alone. Cover, as applicable: - Figure type and overall structure (e.g., bar chart, flowchart, photograph, schematic) - Key elements: labels, axes, data values, components, or steps - Relationships, trends, comparisons, sequences, or hierarchies shown - Outcomes, conclusions, or emphasis the figure conveys …

How to install
mdr add ahgraber/skills/alt-text@sha256:d8309d6495cb9a38The line at the top of this page pins the label git:20260819.209d97b, 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.
