+description: "Save full session context on /new or /reset with slugged filenames in user timezone"
+metadata:

+# Session Memory Custom Hook
+
+Writes full user/assistant transcript context from the previous session into
+`<workspace>/memory/YYYY-MM-DD-slug.md` when `/new` or `/reset` runs.
+
+Differences from bundled session-memory:
+
+- Uses full session context in output file
+- Uses `agents.defaults.userTimezone` (fallback host timezone) for date/time
+- Uses reduced excerpt only for slug generation
