[gotcha] Embedding secrets or authorization logic in the system prompt

Never put secrets \(API keys, passwords\) in the system prompt. Treat the system prompt as public knowledge. Use external validation for authorization instead of relying on the LLM to enforce it.

Journey Context:
Developers often embed API keys or authorization logic in the system prompt, thinking the LLM will 'obey' the instruction not to reveal it. Prompt injection easily extracts this. The LLM is a text predictor, not a secure enclave; it cannot reliably keep secrets from adversarial prompting.
