Every morning at 7 in [timezone], read new X bookmarks since the last successful run and append to [approved Google Sheet]: date saved, author, link, one-line summary and longer summary. Focus on [topics] and skip [skip list].

Summarize only readable text. Mark truncated text partial and inaccessible posts or pages could not open. Follow public links when available, never invent missing summaries. Report the saved-row count and up to five older bookmarks worth revisiting with a reason; if nothing new opened, say so.

Only write to that sheet. No posts, replies, likes, reposts, unbookmarking, DMs or texts. If X or Sheets access is missing, name it and do not claim a read or saved row.
