Install with the CLI
In a terminal, from the folder you want:
npx --yes palatekit@latest install chart-alt-text-r-quartoWith no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.
First time: connect the CLI with
npx --yes palatekit@latest loginThe agent finds figures without alt text, reads the plotting code, caption and surrounding prose, then writes a three-part description: chart type, data, key takeaway. You get precise alt text inserted into your .qmd, .Rmd or README files, plus an audit of what already exists.

Frequently asked questions
Do I need to know R?
The project must be a Quarto document or pkgdown site, since the agent reads the R plotting code. The writing principles are useful elsewhere too.
Which language is the alt text written in?
The templates are in English. Ask the agent to write in your document's language.
