trinity vs harness-sdk

trinity: Trinity is an open-source, sovereign AI agents platform designed for building and running autonomous systems with robust governance, auditability, and full infrastructure control. It enables deployment of multi-agent fleets in isolated Docker containers, providing real-time observability, scheduling, and agent-to-agent delegation capabilities.; harness-sdk: This monorepo holds the Strands Agents SDKs for Python and TypeScript plus Strands harness, a fully assembled agent created with one create_harness() call. It runs in your own process and covers the agent loop, tools, MCP, multi-agent patterns, memory, sessions, guardrails, tracing and evals across Bedrock, Anthropic, OpenAI, Gemini and other providers.
