Function-Based Tool Use

Coming Soon

This tutorial is under development. Check back soon for a complete walkthrough.

What you'll learn

This tutorial will walk you through writing JavaScript functions that AI agents can invoke as tools, using the raisin.* API to read and write data, run SQL, and call external services.

Planned outline

1. Prerequisites: a running RaisinDB server and basic JavaScript
2. Create a function: scaffold one with raisindb create function, write a handler that reads and returns a node, and deploy it
3. Use raisin.nodes: create, read, update and delete nodes from a function
4. Use raisin.sql: run queries with bound parameters and process the rows
5. Use raisin.http: call an external API under a network_policy
6. Use raisin.events: emit events that other functions react to
7. Configure triggers: node event, schedule and HTTP triggers
8. Resource limits: memory, time and concurrency
9. Build an agent tool: describe the function with an input_schema, add it to an agent's tools, and watch the agent call it
