Agents Make a Plan BEFORE They Start

Smart agents write a plan before doing anything.

The big idea

The best AI agents write a plan first. Then they do the steps one at a time — just like you with a project.

Some examples

Step 1: search for facts. Step 2: write a draft. Step 3: check it.
Plans help agents stay on track.
If something breaks, the plan helps them recover.
Plan-first agents are smarter than 'just do it' agents.

Try it!

Ask AI: 'Make a 3-step plan to bake cookies, then explain each step.' Notice how the plan comes first.

Why planning before acting leads to better results

Have you ever started building something without reading the instructions first, and then had to tear it apart halfway through? That's what happens when AI agents skip the planning step. A planning-first agent looks at the entire task before taking any action. It asks itself: 'What's the goal? What are the steps? What could go wrong? What order makes the most sense?' Only after answering those questions does it start acting. This process is called decomposition — breaking a big goal into smaller, ordered steps. An agent asked to 'plan a school fundraiser' might decompose it into: research similar events, pick a date, draft a budget, create a sign-up form, and write announcements. Each step feeds into the next. Skipping decomposition leads to agents that get halfway through a task, realize they've forgotten a key step, and have to backtrack — wasting time and sometimes causing errors that are hard to undo.

Decomposition: breaking a big task into small ordered steps before starting
Dependency order: figuring out which steps must happen before others can begin
Risk preview: spotting which steps are most likely to go wrong before they do
Plan approval: showing the plan to a human before executing any irreversible actions

What is the main idea of "Agents Make a Plan BEFORE They Start"?
1. Smart agents write a plan before doing anything.
2. Use AI as the final authority for the whole decision
3. Avoid checking the answer once it sounds polished
4. Focus only on speed instead of judgment
Which concept is most central to "Agents Make a Plan BEFORE They Start"?
1. decomposition
2. plan-then-do
3. task steps
4. dependency order
Which use of AI fits this topic best?
1. Let the AI decide what matters without your review
2. Use the answer before checking whether it fits the situation
3. Step 1: search for facts. Step 2: write a draft. Step 3: check it.
4. Trust the first answer because it sounds confident
What should a careful learner remember about "Plan first, do second"?
1. AI agents do better work when they make a plan before acting.
2. Skip the context so the tool can guess faster
3. Treat the output as private even after sharing it online
4. Use the answer without checking the source
You want to use AI after this lesson. What is the safest next step?
1. Act immediately because the AI answer is written clearly
2. Use short, concrete wording and ask a trusted adult when the stakes matter.
3. Hide uncertainty so the final answer looks cleaner
4. Use private or sensitive details before checking permission
How should AI output about plan-then-do be treated?
1. As proof that no other source is needed
2. As a replacement for context, consent, or expert review
3. As a draft or helper output that still needs human judgment and verification
4. As something that becomes correct when it sounds confident
Name one way to verify an AI answer about plan-then-do.
Which action would help you apply "Agents Make a Plan BEFORE They Start" responsibly?
1. Use the tool to avoid thinking through the tradeoff
2. Keep going even if the output conflicts with a trusted source
