[FEATURE] Account-level CLAUDE.md

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Currently, ~/.claude/CLAUDE.md is stored locally on each machine. Users who work across multiple computers (e.g., work desktop and personal laptop) have no built-in way to keep their global instructions synchronized.

Proposed Solution

Add an account-level CLAUDE.md that:

• Syncs automatically when logged into the same Anthropic account
• Has clear precedence rules (e.g., local ~/.claude/CLAUDE.md could override or extend account-level settings)
• Optionally allows per-machine opt-out if needed

Claude.md hierarchy would be:

1. Project Level
2. Machine Level
3. Account Level

Alternative Solutions

There are multiple workarounds currently:

• dotfiles git repository with symlinks
• Cloud storage sync (Dropbox, OneDrive, etc.)
• Manual copying between machines

I will try the dotfile git repository.

Priority

Low - Nice to have

Configuration and settings

Use Case Example

A developer using Claude Code on both a work desktop and a laptop wants the same global preferences (coding conventions, feedback style, platform-specific guidelines) applied automatically on both machines without manual synchronization.
