For the complete documentation index, see https://buildwithfern.com/learn/llms.txt. ## 5.68.0 **`(feat):`** Add an `auto-generate-idempotency-key` generator config key. When enabled, the CLI records idempotency-key auto-generation in the IR (`SdkConfig.idempotencyKeyGeneration`) so every generator reads a single, canonical setting from the IR instead of each defining its own config key. Accepts `true` or `{ header-name: "Idempotency-Key" }` and is stripped from the config forwarded to generators.
