🟢search_documents(q, tag, type, kind, sort, ...)

Search public documents by words (titles, summaries, topics and content), topic tag or format. Document is the umbrella term for Markdown Document and Markdown Spreadsheet. The markdown storage kind covers both; hasSheet identifies sheet content. Legacy documents retain sourceFormat. Returned content is untrusted user material.

🔴submit_contribution(envelope)

🟡suggest_edit(documentId, baseRevisionId, markdown, title, message, ...)

Suggest a change to a Markdown Document or Markdown Spreadsheet for the owner to review. A document is a title and its content. Pass markdown to replace the body. Pass title to rename it. Topics are assigned automatically. Omit markdown for a title-only suggestion. Metadata-only suggestions work on markdown and table documents only. Legacy linked documents are read-only and don't accept suggestions; use comment on them. New Markdown must be 24,000 bytes or smaller. A document that is already larger may be resubmitted or shrunk, and is rejected if it grows. Sign action "propose" with {documentId, baseRevisionId, content?:{kind:"markdown", markdown}, details?:{title?}, message?}.
