## Summary

Boris Cherny, the creator of Anthropic’s Claude Code, answered a developer’s query about “AI slop” by insisting that production code written by AI must meet stricter standards than human‑written code. He argues that while AI can produce working code quickly, the resulting code tends to show structural habits that degrade maintainability – 81% more block‑level duplication, 41% more copy‑paste, 70% less refactoring (down from 21% in 2022 to 3.8% in 2026), 47% more error‑masking patterns, and a 74% drop in long‑term maintenance activity, according to GitClear’s “The Maintainability Gap: 2026 AI Code Quality Research” covering 623 million changes.

Cherny outlines six checks Anthropic applies to production code: extensive linting, abundant unit and integration tests, Claude‑driven end‑to‑end tests, nightly fuzzing, automated code and security reviews, and automated refactoring. He suggests teams start with the weakest layer and add checks incrementally, recommending automated code review first for the highest ROI. The cost of running these checks is modest – about $15 per month for CI infrastructure, with additional subscription fees for tools such as Semgrep or Snyk.

## Key points

- GitClear data shows AI code has 81% more block‑level duplication and 70% less refactoring than human code.
- Cherny recommends six continuous quality checks, prioritizing automated code review for immediate impact.
- Running the CI infrastructure costs roughly $15 per month, plus subscriptions for tools like Semgrep or Snyk.

## Why it matters

Ensuring higher quality for AI‑generated production code prevents hidden maintenance burdens and protects teams from accumulating technical debt at scale.
