Best Practices

Writing System Prompts That Work

01

Name every tool explicitly

List each sheet with what it contains. The agent picks tools based on descriptions — vague names = wrong lookups.

02

Always add a fallback rule

"If not in any sheet, say X." Without it, the LLM hallucinates an answer rather than admitting it doesn't know.

03

Define the tone in one line

"Warm", "concise", "professional" — one word shapes every response. Match it to your audience and context.

04

Add domain-specific constraints

"Never show sold listings", "always check allergens first" — hard rules prevent the most costly LLM mistakes.

05

Keep sheets plain and tabular

Clear column headers, no merged cells. The LLM reads headers as field names — make them short and descriptive.

06

Test with unanswerable questions

Ask things your sheet can't answer and verify the fallback fires. Ask cross-sheet questions and check both tools are used.
