Writing about Agentic Engineering Patterns

Takeaways

• Simon Willison launches Agentic Engineering Patterns—structured guide for pro engineers using coding agents (Claude Code, Codex), distinct from vibe coding (no attention to code).
• Agentic Engineering = agents that generate and execute code, iterating with tests independently; amplifies expert judgment rather than replacing it.
• Format: Design Patterns–inspired chapters in a new “guide” content type—evergreen, updatable posts with less prominent dates.
• First chapters: “Writing code is cheap now” (economic/team intuition shift) and “Red/green TDD” (test-first helps agents write succinct, reliable code).
• Policy: prose is human-written; LLMs used for proofreading and example code side tasks only.

Notes

High-signal vault anchor for agentic coding practices; complements Zen of AI Coding thesis and vault /commit + skill workflows. Guide CMS models implemented largely via Claude Code.
