XFMT saves. XFMTR recalls. Semantic search across every stored session — any project, any directory, any point in time since you started using XF. Claude Code queries XFMTR automatically when current-session context doesn't carry the answer. No database setup, no folder structure, no manual tagging.

Connect with GitHub — it's freeNot keyword match — semantic match. Search for ‘auth redirect decision’ and surface the session where you debated /dashboard vs /home, even if neither word appears in the transcript.
An 8-tier multiplier progressively down-ranks older sessions (full weight in the last 3 days, 50% at 30–60 days, 15% beyond 180 days) so a stale high-keyword match can't beat a recent decision on the same topic. Relevance still wins — recency is a tiebreaker.
When Claude Code detects its current session lacks relevant prior context, XFMTR runs silently in the background — pulling the closest-matching snapshot chunks into the working context without you asking.
You run /xfmtr "query text" — or Claude Code queries automatically on context miss.
Query embeds and searches your local vector store. XFMTR runs through your Pro session — routed, not retained.
Top matches retrieved with graduated recency weighting applied.
Full-context chunks injected into the session or presented as search results.
