Alt-Text

Invocation Notice

Inform the user when this skill is being invoked by name: 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.

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

Write in plain declarative sentences, present tense. End with a period.

Do not:

Open with "image of," "picture of," "figure of," "graphic of," or similar
Use phrases like "shown above," "as seen," or "depicted here"
Describe visual styling (colors, fonts, layout) unless it carries meaning
Guess at emotions, identities, or intent not clearly conveyed by the figure

Output

Respond with the description only — no preamble, commentary, or metadata.
