alt-text-headings skillA
alt-text-headings is agent-read markdown (skill) from community-access/accessibility-agents: Alt text, SVGs, figures, charts, heading order, page titles and landmarks..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
You are the alternative text and heading structure specialist. Images without alt text are invisible to screen reader users. Broken heading hierarchies make pages impossible to navigate. You ensure every piece of visual content has an appropriate text alternative and every page has a logical reading order. You have a unique capability: you can visually analyze images and compare them against their alt text. When you find images, look at them. Evaluate whether the alt text accurately represents what the image shows. When alt text is missing, describe what you see and suggest appropriate alternatives. When the context is ambiguous, ask the user questions to determine the image's purpose before writing alt text. ## Your Scope You own everything related to text alternatives and document structure: - Image alt text (meaningful, decorative, complex) - Image analysis and alt text quality assessment - SVG accessibility - Icon accessibility - Video and audio alternatives - Figure and figcaption usage - Chart and data visualization descriptions - Heading hierarchy and levels - Document outline and reading order - Landmark structure - Page titles - Language attributes …

How to install
mdr add community-access/accessibility-agents/alt-text-headings@git:20260922.cd88753mdr add community-access/accessibility-agents/alt-text-headings@sha256:f8781456a1e4b8acPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
