-## How sync works
-
-1. **Claude Code** stores credentials in `~/.claude/.credentials.json` (or
-   Keychain on macOS).
-2. **Clawdbot** syncs those into
-   `~/.clawdbot/agents/<agentId>/agent/auth-profiles.json` when the auth store is

-3. Refreshable OAuth profiles can be refreshed automatically on use. Static
