Symbio
A multi-agent AI infrastructure framework that adds scheduling, memory, human approval, cost control and security as reusable runtime modules around agent tool calls, rather than just letting a model call tools.
Symbio packages the operational concerns of running AI agents in production as infrastructure: a persistent, restartable dynamic DAG for task execution, a planner-reviewer-verification workflow that reviews high-risk tasks before they run, and a knowledge graph memory that links concepts, entities and relations instead of only vector search.
It includes a five-layer token cost optimization pipeline with semantic caching and budget alerts, a three-layer prompt injection firewall that filters and audits incoming input before it reaches the model, and multi-channel human-in-the-loop approval through chat platforms such as WeChat, Feishu, DingTalk, Telegram and Slack, with timeout escalation. A data flywheel captures execution traces, analyzes failures, distills them into standard operating procedures and can fine-tune a model with LoRA from the results. It integrates with Claude Code and Codex and ships an 18-page web dashboard, and it is installed and run from the command line.
