Rules File Hierarchy Design

Format: Design a multi-layered context file structure.

Hierarchy:

~/.claude/rules/           ← Global rules (apply to all projects)
  coding-style.md          ← Coding style
  security.md              ← Security standards

project/.claude/rules/     ← Project rules (apply to current project)
  architecture.md          ← Architectural decisions
  conventions.md           ← Project conventions

CLAUDE.md                  ← Project entry point (most important context)
SPEC.md                    ← Feature specification

Exercise: Design this hierarchy for your project, ensuring:

• No duplication (each rule appears in only one place)
• No contradictions (lower levels don't override critical higher-level rules)
• Concise enough (each file no more than 50 lines)
