5 Agent PATTERNS to SIMPLIFY Your Agentic Coding (Claude Code, Gemini CLI, MCP)

Key takeaways

💡The core problem is not building agents, but understanding the optimal interaction pattern to integrate them with existing systems and services for maximum leverage.00:20
🎯Agent interaction patterns represent a spectrum of complexity and compute, from simple iterative prompts to full-blown applications, each suited for different problem scales.03:50
🚀Start with the simplest pattern (e.g., iterative human-in-the-loop prompts) to solve immediate problems and gain understanding, then incrementally scale up as repetition or complexity demands.03:57
📈Reusable prompts are the 80/20 of agent interaction, offering significant leverage by codifying common tasks and enabling rapid iteration and version control.05:02
🔧Sub-agents are best used for specialization and parallelization when interacting with external services, allowing for dedicated agents to handle specific tasks.06:44
🧩Wrapper MCP servers act as an interface layer, encapsulating multiple services, APIs, or CLIs into a single, controllable point for agents, ideal for complex or proprietary integrations.12:04
