Wes McKinney on Agentic Engineering at Kenn: Quality over Loops
rseroter · x · 2026-08-18
Wes McKinney (creator of Pandas) shares insights into the agentic engineering process and culture at Kenn Software. With a team of three, they merge hundreds of PRs weekly while maintaining a low bug rate across millions of lines of production code.
Key Takeaways:
- Against Fully Autonomous Loops: McKinney asserts that claims of fully autonomous, no-human-in-the-loop agent pipelines producing high-quality code are usually misleading—either from cluelessness or salesmanship.
- Quality at High Cost: Despite his massive token consumption (with a potential monthly cost over $56,000), he emphasizes that精心设计的 workflows allow for heavy AI usage without sacrificing code quality or taste.
- Vibe Coding vs Agentic Engineering: Citing Jesse Vincent, he defines true agentic engineering as “planning, architecture, and… caring about the output,” contrasting it with “Vibe Coding,” which he describes as “not caring at scale.”
The article details their specific workflow, tech stack, and architectural strategies for effective AI-assisted development.
