Multi-Agent-AI-System

The Problem

Complex AI tasks required autonomous orchestration of multiple specialized agents with tool-based workflows and collaborative decision-making.

The Solution

Engineered a Multi-Agent AI System capable of autonomous task decomposition and execution using tool-based workflows and collaborative agent architectures. Implemented agent coordination patterns with TypeScript for reliable multi-step task completion.

Impact

Advanced agentic AI system for autonomous task execution with intelligent agent collaboration.

Architecture

Key Challenges

• Agent loops were the biggest reliability problem — agents would call tools repeatedly without making progress when they received ambiguous results. Fixed by implementing a step counter per agent with a hard ceiling and a fallback instruction that forces the agent to return its best partial result rather than looping indefinitely.
• Typed inter-agent communication was essential for reliability but LLMs don't naturally produce consistent JSON schemas. Used Zod schema validation on all agent outputs and built an auto-correction loop that re-prompts with the schema error when validation fails.
• Coordinating parallel subtasks without race conditions required careful state management. Implemented a task dependency graph so the coordinator only dispatches a subtask when all its dependencies are resolved, preventing agents from working with incomplete context.

Key Learnings

Multi-agent systems are only as reliable as their weakest agent's output schema. The most valuable engineering investment was the validation and retry layer, not the agents themselves. I also learned that giving agents too many tools degrades performance — fewer, well-scoped tools with clear descriptions outperform large toolsets with vague ones.
