Feature: Auto-switch accounts when rate limited

Problem

When using Claude Code with multiple accounts (personal, work, etc.), hitting a rate limit on one account requires manually:

1. Running /logout
2. Running claude again
3. Logging in with a different account
4. Losing conversation context

Proposed Solution

Automatic account rotation when rate limited:

1. Store multiple account credentials (securely in keychain)
2. On rate limit, automatically switch to next account with available quota
3. Continue the conversation seamlessly

Configuration

{
  "accounts": ["personal", "work", "client"],
  "autoRotateOnRateLimit": true
}

Implementation Ideas

• Use CLAUDE_CONFIG_DIR env var to isolate account configs
• Store OAuth tokens per account in separate config directories
• On rate limit response, try next account automatically

Prior Art

• CCS (Claude Code Switch) attempts this but has reliability issues
• cc-account-switcher provides manual switching

User Benefit

• Uninterrupted workflow for heavy users with multiple accounts
• Better utilization of available quota across accounts
• No manual intervention needed when hitting limits
