What it does

Agents

The business value is not that AI can click buttons. The value is a controlled worker that researches, summarizes, routes, or drafts while humans stay in charge of risky actions.

Stack to use

Recommended setup

OpenAI Agents SDK or equivalent agent framework
Serverless backend or worker
Tool definitions for CRM, email, database, or search
Supabase or log table for traces
Human approval queue
Guardrails for blocked actions
Error and rollback process

Common mistakes

What to avoid

Giving the agent too much access too early.
No approval step.
No logs.
No clear success metric.
Letting it send messages without review.

Implementation

Build the workflow step by step.

Connect the smallest useful flow first, make ownership clear, then measure it before expanding.

Step 1

Define the agent goal in one sentence.

Step 2

List exactly which tools it can use.

Step 3

Create read-only tools first.

Step 4

Add logs for every tool call and decision.

Step 5

Add human approval before messages, CRM changes, purchases, or sensitive actions.

Step 6

Test with fake records before touching real data.

Step 7

Review traces weekly and tighten rules.
