How to Build an AI Agent That Actually Works
A grounded guide to agent design that starts with workflow clarity, not with a framework logo and wishful thinking.
Most agent projects fail early for a simple reason. The workflow itself was vague before automation started.
An agent is a coordination system. If the task, reviews, inputs, and outputs are fuzzy, the agent will be fuzzy too.
Start with the workflow
Define the job in plain language. What triggers it. What data it needs. What counts as a good output. Who reviews it.
If those answers are not crisp, you are not ready to automate.
Separate reasoning, generation, and action
Different steps often need different models or different rules. Planning is not the same task as writing. Writing is not the same task as publishing.
Breaking the flow apart makes debugging possible.
Keep a review loop until the system earns trust
Skipping review is usually framed as efficiency. More often it is just optimism.
Good agents make review cheap. They do not pretend review is unnecessary.
