+Immediately persist the current session context to memory.
+
+## Process
+
+1. **Read current index.md** — Load existing context
+
+2. **Update with current session:**
+   - What we're working on
+   - Current state/progress
+   - Any new preferences or patterns discovered
+   - Next steps to continue
+
+3. **Write updated index.md** — Replace content with condensed, current version
+
+4. **Checkpoint other files if needed:**
+   - `patterns.md` — Add new patterns discovered
+   - `chronology.md` — Add session summary if significant
+
+## Output
+
+Confirm save with brief summary: "Memory saved. {brief-summary-of-what-was-updated}"
