Decisions

Decision guides explain practical starting points and the tradeoffs behind them.

Use these pages when choosing technologies for an agent-native system:

• Protocol Selection
• API Style
• Memory Store Selection
• Model Deployment
• Agent Framework Selection

Recommended Starting Points

Area	Starting point
Protocols	A2A for agent-to-agent work, MCP for agent-to-tool work, OpenAPI for deterministic APIs
API style	REST with OpenAPI first; GraphQL only when query flexibility is needed
Memory	Qdrant-style vector index plus Neo4j-style graph model for the demo architecture
Models	Model gateway abstraction with hosted primary routes and local private classification route
Agent framework	Start with explicit orchestration; evaluate LangGraph for stateful long-running workflows
