Advanced Agents From First Principles 03: Does Your Agent Commit to a Bad Reasoning Path Too Early? Build a Tree of Thoughts

A reasoning agent can fail even when every individual step looks plausible.

The problem is often not that the model cannot produce a good line of reasoning.

The problem is that it commits too early.

It chooses one interpretation, one hypothesis, one plan, or one next step and then spends the rest of the run trying to make that decision work.

That gives us a common failure pattern:

problem
  ↓
first plausible thought
  ↓
second thought conditioned on the first
  ↓
third thought conditioned on both
  ↓
...
  ↓
confident answer built on an early mistake

If the first branch was wrong, every later step inherits the error.
