Some opinionated etiquettes for AI-assisted code generation, inspired by the Boy Scout Rule. Covers writing human-readable code in hybrid codebases, reviewing AI-generated code and PR descriptions, acknowledging AI in commit messages, maintaining project steering rules, avoiding test manipulation, structuring code review feedback across linters, AI agents, and humans, and evaluating AI-introduced dependencies. Based on hands-on experimentation with agentic engineering workflows, not research data.
