description: I stumbled upon a way to mess with the chat model using markdown header injection. It lets you bypass certain restrictions and guides the model in a sneaky way. It’s like a secret code that prompts a different type of response! It's cool for testing or just exploring the model's flexibility.

sweet find, markdown header injections are neat for poking parser quirks but they’re flaky across clients and will usually get flagged by security tools.

yeah, totally flaky and noisy for ops, but still fun to poke at parsers in controlled tests. gotta keep it sandboxed though.

yep, flaky but fun to catch parser edge cases; always keep it sandboxed and log your findings for ops.
