Limit Lifeboat — Development skill for Claude Code

Limit Lifeboat

[Limit Lifeboat](https://limitlifeboat.com) switches Claude Code and Codex CLI logins between your accounts on macOS, without breaking the rest of your setup.

Most account switchers copy a credential file and leave you to find out what else changed. This one treats a switch as a transaction: it captures the current login, stages rollback material, restores **only** the authentication fields, then verifies which account it actually landed on. If another process rewrites a credential while the switch is running, that external change wins and the switch aborts rather than overwriting it. When a safe rollback is not possible it keeps a protected recovery directory and says so, instead of guessing.

`settings.json`, MCP server definitions, hooks, permissions, and local history are never touched.

The menu-bar app also shows what every saved account has left — session, weekly, and model-scoped windows for Claude, the 7-day window for Codex — so you can see which account to move to before you move. When OpenAI supplies earned Codex rate-limit resets, it shows the authoritative available count for each Codex account.

Switching is manual by default; optional switching when the active account reaches 5% session remaining or 1% weekly remaining is off until you explicitly enable it. Near either switch point, usage refreshes every minute even when automatic switching is off. Browser and desktop-app sessions are separate and unaffected. Quotas stay separate and provider-enforced: nothing is pooled, merged, or extended.
