System Prompts
Shape assistant behavior with clear instructions.
The system prompt tells the LLM how to behave. Keep it short, explicit, and grounded in your domain.
When tools are configured, DatabaseChat automatically appends generic tool
reliability guidance by default. This teaches the assistant to use meta.count
for exact totals, treat paginated list results as pages, use
meta.pagination.nextCursor for immediate "show more" follow-ups, and avoid
using semantic search result length as a factual count.
const chat = defineDatabaseChat(components.databaseChat, {
systemPrompt: SYSTEM_PROMPT,
tools,
toolGuidance: "auto", // default
});Use toolGuidance: "disabled" if your system prompt fully owns those rules, or
pass a custom string to append your own tool-result instructions instead of the
generated guidance.
