/hall:prune

Clean up older plans or stale cache from .hall-cache/.

Flag detection

Run this first, before any other logic:

RESET_INVOKER=false
for arg in "$@"; do
  [ "$arg" = "--invoker" ] && RESET_INVOKER=true
done

--invoker

Reset the invoker-status cache. Use this after joining automata-invokers or switching orgs.

If RESET_INVOKER=true:

[ -f .hall-cache/invoker.json ] && rm .hall-cache/invoker.json
echo "Invoker cache cleared. Run /hall:open to re-verify."

Exit immediately after. Do not proceed to --plans or --cache logic.

--plans

List plan directories older than N days. Show sizes. Ask for confirmation before removing.

find .hall-cache/plans -maxdepth 1 -type d -mtime +<N> | sort

Never prune the most recent plan regardless of age.

.hall-cache/invoker.json is not touched by this step.

--cache

Remove .hall-cache/personas/ (forces a fresh fetch on next /hall:open).

rm -rf .hall-cache/personas/
echo "Persona cache cleared. Next /hall:open will re-fetch."

.hall-cache/invoker.json is not touched by this step.
