One lean CLAUDE.md file with auto memory for workflows

8/ The real setup, start to finish. One lean CLAUDE.md. Let auto memory handle lessons. Add path rules when it grows, skills for workflows. Most people manage 7 files to do what one file and the tool already handle.

6/ For a big or messy codebase, do not pile it all into one file. Use path-scoped rules in a .claude/rules/ folder. They load only when Claude touches the matching part of your code, so your context stays clean instead of carrying everything at once.

5/ The lessons.md file is now pointless. Claude Code has auto memory. It writes down what it learns about your project on its own, after you correct it, and reloads it next session. The tool already does the thing people are telling you to do by hand.

3/ Start with one file. CLAUDE.md in your project root. Build commands, your folder layout, conventions, the "always do this" rules. Claude reads it at the start of every session. This one file does what those seven were trying to do.

2/ Anthropic lists the actual ways to steer Claude Code. There are seven, and they are not files you invent. CLAUDE.md. Rules. Skills. Subagents. Hooks. Output styles. System prompt. That is the real list. Everything else is noise.

Claude Code auto-loads specific files, not all recommended markdown files

1/ The viral advice says make persona.md, lessons.md, references.md, glossary.md, and more. Claude Code does not read most of them. It auto-loads a specific set of files. The rest just sit there unless you import them by hand.
