Agentic Tool-Calling Prompt Templates: Enabling Deterministic Function Calling for Autonomous Workflows

Autonomous AI agents become truly powerful when they can interact with the physical and digital world—fetching database records, making HTTP API calls, or executing terminal scripts. Enabling LLMs to select and call external tools deterministically requires specialized tool-calling prompt templates.

1. Production Tool-Calling Prompt Schema

```markdown

You are an Autonomous Logistics Agent. You have access to the following tools:

1. `fetch_weather(city: string)`: Returns current temperature.

2. `search_database(query: string)`: Searches internal inventory.

TOOL CALL FORMAT:

If a tool call is required, respond ONLY with a JSON object:

{

"tool": "tool_name",

"arguments": { "arg_name": "value" }

}

Do not add conversational text around tool calls.
