MemCube v2 and SMRS v1.0 — formal specifications for interoperable, provably safe agent memory governance.
A standardized JSON Schema for AI agent memory entries. Designed for interoperability across LangChain, CrewAI, AutoGen, LangGraph, mem0, and any agent framework.
| Field | Type | Description |
|---|---|---|
| id | string | Unique identifier |
| content | string | Memory content text |
| type | enum | One of 7 memory types |
| timestamp_age_days | float | Age in days since creation |
| source_trust | float 0-1 | Source reliability score |
| source_conflict | float 0-1 | Contradiction level with other sources |
| downstream_count | int | Number of dependent agents |
