Agent Loop Engineering

Multi-Step Planning vs Reactive Loops

Should your agent plan the whole task upfront or figure it out step by step? A multi-step planning agent and a reactive loop fail in opposite ways. This guide helps you choose and combine them.

How to Add a Verification Step Before the Final Answer

Picture your agent confidently returning a wrong number to a customer. An agent verification step catches these before they ship. Here's a teardown of a weak final-answer flow and its fix.

Confidence Scoring to Decide When to Stop

Agents that stop on a fixed step count are wrong twice: they quit too early on hard tasks and grind pointlessly on easy ones. Agent confidence scoring fixes both. Here's a real rollout.

Dynamic Tool Selection Within the Loop

An agent handed 40 tools picked the wrong one 30% of the time. A dynamic tool selection agent narrows the toolset each step so the model chooses well. Here's how to build one.

Adding Backtracking to the Agent Loop

Most agent guides are wrong about failure: they retry the last step when the real problem was three steps back. Agent backtracking lets your loop undo a bad decision instead of digging deeper.

Why Your Agent Repeats the Same Action

Ever watched your agent call the same tool over and over? The agent repeating actions fix is almost never a bigger model — it's memory and feedback. Here's the teardown.

Debugging an Agent That Loops Forever

When an agent gets stuck in a loop, it burns budget and never returns an answer. This case study walks through diagnosing and fixing a real infinite-loop agent step by step.

How to Tune an Agent Loop for Fewer Steps

Most bloated agents take twice the steps they need. Learn how to reduce agent loop steps by front-loading context and giving the loop a real stop condition — no bigger model required.

The Prompts That Drive Each Loop Step

One vague system prompt was making an agent loop badly — wrong tools, no stopping, no progress. Great agent loop prompts drive each step deliberately. Here's the teardown and the fix.

Cost per Loop Iteration: Budgeting Token Spend

Most teams budget agent loop token cost by the total and miss where it actually goes. Here's a case where the real cost hid in re-sent context, and the fix that cut spend 60%.

How to Handle Partial Failures Inside the Loop

What happens when one tool call in a batch fails but the rest succeed? Handling agent loop partial failure well is the difference between a resilient agent and one that dies on a hiccup.

Checkpointing Agent State Between Iterations

Agent loop checkpointing saves the agent's state each iteration so a crash costs one step, not the whole run. Here's how to checkpoint what matters, cheaply, without slowing the loop.
