KC Tech Enthusiasts - Agentic AI Design Patterns with Claude Code

At the KC Tech Enthusiasts Meetup, I presented some recently emerging design patterns for developing agentic AI systems based on research from Anthropic

KC Tech Enthusiasts - Agentic AI Design Patterns with Claude Code

Intro

  • KC Tech Book Club

  • KC Tech Enthusiasts
    • Cayden Sommer
    • Jesse Saunders
    • Evan Harmon

  • Intros
    • Name
    • Background
    • What you’d like to get out of today?

Today

  • Quick Talk
    • AI
    • Agentic AI
    • Claude Code

  • Quick Demo of Claude Code
  • Share strategies, learn from others, Q&A, dive deeper
  • …?
  • Profit

AI

  • LLM plateau

  • Agentic AI

  • Similar problems
    • Hallucinations
    • High level reasoning and understanding falls short
    • Adding compute and huge context windows don’t fix it
    • Frequently need to start over with fresh context

  • Back to traditional engineering

  • Designing complete systems

  • Agentic AI

  • Managing memory

  • Efficiently and automatically tracking progress
  • Feedback loops with clearly defined success/failures
    • E.g. only allowed to change when it passes a unit test

Design Pattern for Agentic AI

  • A way to use agents in a repeatable way that requires designing and setting up harnesses that reliably manage the memory use of your AI

  • State
    • Context/facts

  • What counts as success/fail
  • How to approach problems
  • How to track progress

  • (Sounds similar to software architecture patterns)
  • Context Engineering

Claude Code

  • Anthropic Research
    • Honing in on this design pattern

  • Initializer agent and coding agent
    • Initializer agent sets the stage with the user prompt and how it sets the memory on other agents so that every other run with coding agents has dynamic context
  • Why Claude Code has tooling that makes it easier to use this pattern

  • .claude folder
  • claude.md
  • agent.md

  • rules.md
  • tools
  • mcp

Demo

  • how I’ve been using it

  • what’s working well
    • mowing bidder
    • mcp
    • Claude project instructions

  • not working well
    • zoho
