Build Your First Agent Without a Framework
vexlowhq · reddit · 2026-07-14
The author wrote a hands-on tutorial on building your first AI agent without using any frameworks, keeping only the most basic loop: Goal → Call Tool → Observe → Decide.
They highlight several practical tips:
- Prompts should describe the "result/goal" rather than hardcoding the steps
- Start by exposing only 2 tools to avoid complexity
- Enforcing a hard step limit is more important than "choosing the most powerful model"
- You must log every step, or it will be incredibly hard to understand what the agent actually did
The author also asks for feedback: do people actively avoid frameworks when building agents, or are the benefits just too good to pass up?
