TIER 1: SINGLE-AGENT PATTERNS
- ReAct: Alternates between reasoning and acting, ensuring the agent thinks before every tool call.
- Plan-and-Execute: Generates the full task plan upfront, then executes each step sequentially.
- Reflection / Self-Critique: The agent reviews its own output and iterates until satisfied.
- Tool Use / Function Calling: The agent decides which external tool to invoke and when.
TIER 2: MULTI-AGENT ORCHESTRATION
- Orchestrator-Subagent: A coordinator agent manages and delegates tasks to multiple subagents.
