attribute

prefix: str | SystemMessage | None

Text placed before the base prompt.

attribute

base: str | SystemMessage | None

Replacement for the built-in base prompt.

Omit the key to keep the built-in base (or the active HarnessProfile.base_system_prompt). Set it to None to drop the base entirely, leaving only prefix, suffix, and middleware-contributed content.

attribute

suffix: str | SystemMessage | None

Text placed after the base prompt.

Structured system_prompt for create_deep_agent.

All keys are optional. Each accepts a str or a SystemMessage (to carry explicit cache_control markers).
