Our Hong Kong multi-agent orchestration follows a methodology for complex agent systems: (1) Process decomposition (weeks 1-2): breaking down complex processes. Task analysis: decomposing target business processes into discrete tasks — each task becoming a potential agent responsibility. Agent roles: defining agent specialisations — researcher, analyst, writer, reviewer, executor, communicator, and monitor. Hong Kong specifics: identifying bilingual requirements (agents needing Chinese and English), regulatory requirements (SFC, HKMA compliance), and cross-border data handling. Orchestration pattern: designing how agents coordinate. Patterns: sequential (agent A → agent B → agent C), parallel (agents A and B simultaneously → agent C merges), hierarchical (supervisor agent directing specialist agents), and reactive (agents responding to events). Human-in-the-loop: defining approval gates — which agent outputs require human review before proceeding. (2) Agent development (weeks 2-4): building specialised agents. LLM backbone: selecting models for each agent role — GPT-4o for general reasoning, Claude for complex analysis, and specialised fine-tuned models for domain-specific tasks. Chinese: agents handling Chinese requiring strong bilingual LLM capability — understanding Traditional Chinese (Hong Kong), Simplified Chinese (mainland documents), and code-switching between Chinese and English. Tools: building agent tools — database query tools (agents accessing business databases), API tools (agents calling external services), document tools (agents reading and generating documents), and communication tools (agents sending notifications and messages). Memory: agent memory systems — short-term (current task context), long-term (learned patterns and preferences), and shared (knowledge accessible to all agents in the orchestration). (3) Orchestration layer (weeks 3-5): building coordination. Orchestrator: building the system that coordinates agent activities — task assignment, agent communication, state management, and error handling. Frameworks: LangGraph (graph-based orchestration), CrewAI (role-based agent teams), AutoGen (multi-agent conversation), or custom orchestration (maximum control). State: maintaining workflow state — tracking which agents have completed their tasks, what data has been produced, and what remains to be done. Error handling: when an agent fails — retry with different approach, escalate to more capable agent, or flag for human intervention. Quality gates: automated quality checks between agent steps — output verification, consistency checking, and compliance validation. (4) Testing (weeks 4-6): validating multi-agent systems. End-to-end: testing complete workflows — from input trigger through all agent steps to final output. Hong Kong testing: testing with Hong Kong business data — bilingual documents, Hong Kong financial data, and Hong Kong regulatory scenarios. Edge cases: testing unusual scenarios — incomplete data, conflicting information, system unavailability, and unexpected agent outputs. Accuracy: measuring output quality — comparing agent-produced outputs against human expert benchmarks. Speed: measuring orchestration performance — end-to-end processing time versus human team equivalent. Compliance: testing regulatory compliance — audit trail completeness, data handling correctness, and disclosure accuracy. (5) Deployment (weeks 5-7): production operation. Infrastructure: deploying on appropriate infrastructure — Hong Kong data centre for sensitive financial data, cloud for general processing. Monitoring: real-time agent monitoring — task completion rates, processing times, error rates, and quality scores. Cost: LLM cost monitoring and optimisation — routing simple tasks to cheaper models, caching frequent operations, and batching where possible. Scaling: horizontal scaling for volume — adding agent instances during peak periods. Continuous: agent improvement based on production data — refining prompts, expanding tools, and improving orchestration logic.
