📚 Usage Examples
Context Graph - Capture Your Agent Sessions
Turn your coding agents' sessions (Claude Code, Codex, Copilot CLI, Cursor, OpenCode, Antigravity CLI, Grok Build) into a queryable knowledge graph. Every session records the tools it called, the skills it used, and the memories it wrote — all joined on a shared (:Session) node in Memgraph.
One command finds or starts Memgraph, wires every agent it finds, sets your identity and checks the result (interactive on a terminal):
Query across every session — e.g. which skills a user has used:

unstructured2graph - Build Knowledge Graphs from Documents
Transform PDFs, URLs, and documents into queryable knowledge graphs:
extraction_backend is pluggable — LightRAGBackend (LLM-based, shown above) or GLiNER2Backend (local, LLM-free) — see unstructured2graph § choosing an extraction backend.
