Summarize
Give a complete, plain-English account of one thing so the reader can decide or act on it without opening the source. Detail means coverage, not length: every substantive point survives, the padding does not.
Pick the subject
"It" is the most recent deliverable, document, plan, diff, report or thread in the
conversation. /summarize <path or reference> names it directly. If two candidates are
equally recent, ask one line and stop.
Read the whole source before writing, never a preview, an excerpt or your memory of it. If the source is already fully in context, do not reread it. For a diff, read enough of the changed files to know what the change does. For a thread or session, reread the turns the summary covers.
