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.
