+# claude-reap — close Claude sessions that have gone quiet, and say so on their tty.
+#
+# neo is an 8 GB box. A finished session costs as much resident RAM as a working
+# one, and the sessions that killed it twice were mostly *done* — last words
+# "great", "yes", "compush now" — just sitting there. So: reap the quiet ones.
+#
+# Idleness is the mtime of the session's own transcript. Claude rewrites that
+# file on every turn, so a session that is thinking, tool-calling, or streaming
+# keeps touching it; only one waiting on a human goes stale. That makes mtime a
+# truthful "nobody is here" signal, and means we never reap live work.
+#
+# Nothing is lost: the transcript IS the session. We print the `--resume` line
+# onto the terminal we just cleared, so the way back is sitting where the
+# session used to be.
+#
+# Usage:
+#   claude-reap            # reap sessions idle >= IDLE_MINUTES (default 30)
+#   claude-reap 45         # ...with an explicit threshold
+#   claude-reap 30 dry     # report only, kill nothing
