When you call useAgentContext() in your React component, you can set key-value pairs — such as tone, expertise level, response length preferences, or any domain-specific metadata — that travel alongside the user's message to the agent. The agent's system prompt builder reads these values and adjusts its behavior accordingly. For example, setting tone to 'professional' might instruct the agent to avoid slang and use formal sentence structures, while setting expertise to 'expert' would tell it to skip introductory explanations and use domain terminology freely. This context is per-turn, meaning you can change it between messages without restarting the conversation."
