Chain of Thought

Master transparent, step-by-step reasoning for more accurate and explainable AI agents

Breaking Down Complex Reasoning

The heart of chain-of-thought reasoning is decomposition—breaking complex problems into smaller, manageable steps. Each step should be simple enough to verify independently, yet connect logically to form a complete reasoning chain.

Problem:
How many legs do 3 dogs and 2 cats have in total?
📝
Identify what we know: Dogs have 4 legs, cats have 4 legs
🐕
Calculate dog legs: 3 dogs × 4 legs = 12 legs
🐈
Calculate cat legs: 2 cats × 4 legs = 8 legs
Add totals: 12 + 8 = 20 legs
Final answer: 20 legs total

Best Practices for Step-by-Step Reasoning

1️⃣
Start with What You Know
Explicitly state given information, formulas, and constraints before proceeding
2️⃣
One Operation Per Step
Don't combine multiple calculations—break them into individual, verifiable steps
3️⃣
Show Intermediate Results
Display the result of each step before moving to the next one
4️⃣
Use Clear Transitions
Words like "therefore," "next," "now that we know" help connect logical steps
5️⃣
Verify Along the Way
Check if intermediate results make sense before continuing
