284284The SDK also seeds the temporary directory with files from your real config directory. What it copies differs by language:

286* **TypeScript**: credentials, `.claude.json`, and your user `settings.json`. From `settings.json` it strips the keys that misbehave under a temporary config directory: `enabledPlugins`, `extraKnownMarketplaces`, its [`additionalMarketplaces`](/docs/en/settings#extraknownmarketplaces) alias, and any `CLAUDE_CONFIG_DIR` in the file's `env` block. Before Agent SDK v0.3.232, the SDK didn't strip the alias. Auth configured in settings, such as [`apiKeyHelper`](/docs/en/settings#available-settings), works when you resume from the store. Before Agent SDK v0.3.222, the TypeScript SDK copied only credentials and `.claude.json`.

287287* **Python**: credentials and `.claude.json` only, so an app that authenticates through `apiKeyHelper` in your user `settings.json` fails with `Not logged in` when resuming from a store. An `apiKeyHelper` in managed or project settings still works, because Claude Code reads those files from locations that `CLAUDE_CONFIG_DIR` doesn't affect.

289289When the store has nothing for the session, the SDK runs under your real config directory instead, and the outcome depends on which option you passed:
