Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢make_plot_link(document)
Check a Graph Paper plot document and return the link that opens it. The link opens the plot as an editable draft in Graph Paper (https://graph-paper.io); the reader needs no account. Give the document as a JSON object in the format of get_plot_format. If the document has errors, the result lists each one with the path of the field and what to change, and no link; fix them and call the tool again. Warnings name the keys that were ignored.

}🟢get_plot_format(section)
Return the reference of the Graph Paper plot document format, as Markdown: every field of a plot document, the series types, the limits, and complete examples. Give section to get one section only (a heading of the page, such as "Variables" or "2D Series Types"); an unknown section returns the list of headings. Read it before you write a document for make_plot_link.

}🟢list_examples
Return the example plot documents of the Graph Paper format page, each with its title and its JSON. Each one is a valid document that make_plot_link accepts; start from the one closest to what you want.
