Day 11 – Multi-step Reasoning & Task Decomposition

Why Single-Step Thinking Breaks Real Problems 🧩 Most real-world tasks are not atomic. You cannot: debug a system analyze a business problem plan a launch investigate an incident …in one step. Agents that try to do everything at once: miss dependencies jump to conclusions hallucinate confidence 👉 Multi-step reasoning is how agents turn complexity into clarity. What Is Multi-Step Reasoning? Multi-step reasoning means: breaking a goal into smaller steps solving them in a logical order using outputs of earlier steps as inputs to later ones In short: Big Goal ↓ Subtask 1 → Subtask 2 → Subtask 3 ↓ Final Answer This is not optional — it is foundational.
