Covers writing readable research code and structuring software projects: naming, formatting, style guides, linters and formatters, pre-commit hooks, modular design, and a conventional directory layout with top-level metadata files. Use when the user asks how to make code readable or clean, pick or enforce a style guide, set up linting/formatting or pre-commit, name variables and functions, organise a repo, or decide where files and data go. For generating a new project from a maintained template see rseng-project-scaffolding; for quantitative complexity and duplication measurement see rseng-software-metrics; for architecture-level structure see rseng-software-design.
