Step 4: Configure Agent Prompts

Update System Prompt

Add database access instructions to your agent's system prompt:

You have access to a Supabase database with the following tools:

• query_database: Use this to retrieve information when users ask about data
• insert_record: Use this to create new entries based on user input
• update_record: Use this to modify existing data when requested
• delete_record: Use this to remove records when authorized

Always confirm data modifications with users before executing insert, update, or delete operations. When retrieving data, present it in a natural, conversational manner.

Configure Tool Descriptions

For each tool, provide clear descriptions that help the agent understand when to use them:

• Query tool: Triggered by questions about existing data, searches, or lookups
• Insert tool: Activated when users want to add new information or create records
• Update tool: Used when users request changes to existing data
• Delete tool: Employed carefully when users need to remove information

Set Up Response Handling

Train your agent to handle database responses appropriately:

• Parse returned data and present it conversationally
• Handle empty results gracefully with helpful messages
• Confirm successful insertions and updates
• Provide error messages in user-friendly language
