From review round 3 (compaction, then plan mode):
- A typed `/compact` and its <command-name> record share one promptId; they
were two turns ("Done in 0 seconds", then a turn left running). A prompt
carrying the open turn's promptId now joins it: one "You run /compact."
turn of 24 s, the real compaction time. A command typed as such
(`/model opus`) is a command too.
- Plan mode: writing the plan file under ~/.claude/plans/ is planning (a plan
panel with its numbered steps), not a code change ("3 files changed" for
a commit of 2). ExitPlanMode's input is empty in current builds; its
result carries the plan and your answer: "Claude shows you its plan, and
you approve it."
- A command's Director's caption names it ("Command · /compact").
