CLAUDE.md (and AGENTS.md) works best when it reads like a resume, not documentation: short, abstract, and stripped of anything a linter or a hook could already enforce. This piece lays out a seven-part framework — one-line intro, architecture, tech stack, commands, conventions, boundaries, and a domain doc map — plus a trimming strategy that moves overflow content into sub-agents, rules folders, subdirectory CLAUDE.md files, skills, and docs once the file outgrows 200 lines.
