cruxible vs hippo-memory

cruxible: Cruxible is a governed state engine designed for AI agents, transforming YAML ontologies into typed knowledge graphs with enforced write rules. It provides a robust, auditable system for managing an agent's 'hard state', ensuring data integrity and consistency without relying on LLM internal reasoning.; hippo-memory: Hippo is an AI agent memory layer inspired by the human hippocampus, designed to manage agent memory with features like default decay, strengthening through use, and full provenance. It integrates with various AI agents and tools, using SQLite for storage and offering a CLI for memory management, ensuring relevant context is always available without overwhelming the agent.

Features

cruxible logocruxible
01Enforced Write Rules & Governance: Ensures data integrity and consistency for AI agents through configurable write policies, review groups, and attribute-based access control.
02Typed Knowledge Graph from YAML Ontology: Defines entity types, relationships, and queries using a versioned YAML ontology, which can be drafted by agents and refined by humans.
03Deterministic & Receipted Queries: Provides reliable, auditable query answers with receipts, ensuring every agent gets the same answer for the same state.
04Local & Portable State Management: Operates as a Python daemon with CLI/MCP server, storing state in a portable SQLite file, enabling isolated deployment and ownership.
05Integration with External Actions (Gates): Allows external actions (like git pushes) to be gated, meaning they are refused until the governed state agrees.
hippo-memory logohippo-memory
01Default memory decay with configurable half-life.
02Memories are strengthened through retrieval and use.
03Errors and important decisions are given longer persistence.
04Memory consolidation process ('sleep') merges and prunes memories.
05Context injection with token budgeting and flexible framing.
