LangGraph Persistence & Memory
Pass
Audited by Gen Agent Trust Hub on Mar 3, 2026
Risk Level: SAFE
Full Analysis
- Standard Library Dependencies: The skill utilizes official LangChain and LangGraph packages for state management.
- Evidence includes imports of
langgraph.checkpoint,@langchain/langgraph, and@langchain/langgraph-checkpoint-postgres. - These are recognized vendor-owned libraries used for the skill's primary purpose.
- Database Connection Configuration: Production examples include connection string templates for PostgreSQL.
- [Security Consideration]: The code uses a placeholder string (
postgresql://user:pass@localhost/db) to demonstrate database connectivity. - Users are encouraged to replace these placeholders with secure environment variables for production credentials.
- Data Ingestion Surface (Memory): The skill implements long-term memory storage, which involves processing and storing user-provided data.
- Ingestion points: Data enters the system via the
store.putandgraph.update_statefunctions inSKILL.md. - Boundary markers: The provided examples focus on functional logic; explicit delimiters for untrusted content are not shown in these snippets.
- Capability inventory: The skill is restricted to internal graph state management and database interactions; it does not perform arbitrary command execution or external network requests beyond the configured database.
- Sanitization: Standard LangGraph persistence handles serialization of state data.
