Sync Session to Permanent Graph
Bridge session cache entries into the permanent knowledge graph.
Instructions
The sync happens automatically at session end via the shutdown hook. To trigger a manual sync, use a bash command to POST the session's cached Q&A and trace data to the Cognee server's remember endpoint:
curl -s -X POST "${COGNEE_BASE_URL:-http://localhost:8011}/api/v1/remember" \
-H "X-Api-Key: ${COGNEE_API_KEY:-}" \
-F "datasetName=${COGNEE_PLUGIN_DATASET:-agent_sessions}" \
-F "node_set=user_sessions_from_cache" \
-F "run_in_background=false" \
-F "data=<session QA and trace content>"
What this does
- Persist session Q&A — cognifies session text into the permanent graph
- Sync graph to session — copies new graph relationships back into the session cache as a knowledge snapshot, so subsequent completions have instant access to the enriched graph context
- Dedup by content hash — already-synced content is skipped
After this, session entries become searchable via the cognee-search skill or cognee_recall tool, and the graph knowledge is automatically included in session completion prompts.
When to use
- Before searching for session content that hasn't been synced yet
- When you want to force an early sync without waiting for session end
- This runs automatically at session end via the
shutdown hook
