01. CLAUDE.md turns project habits into executable context

Section 1 of 3

CLAUDE.md is a project instruction file that Claude reads at session start. Use it for stable rules: test commands, architecture constraints, package manager, review checklist, naming conventions, and security boundaries. Keep it short enough that the agent will actually follow it.
