Agent Prompt

Hot-swap agent behavior by updating system prompts without redeployment.

Overview

The hyperfold agent prompt commands let you view, update, and manage agent system prompts in real-time. Changes take effect immediately—no redeployment required.

Prompts are stored in Firestore and loaded fresh for each new session. Active sessions continue with their original prompt until completion.
