Designing the Toolbox You Hand Your Agent

fewer, sharper tools beat a giant pile of overlapping ones

Some examples

• Giving an agent only read_file and run_tests
• Skipping tools you do not actually want it to use
• Naming tools so the model picks the right one

Try it!

Open your favorite AI tool and try one of the examples above. Pick the one that matches what you are actually working on this week. Spend 10 minutes, no more. Notice what worked and what did not — that's the real lesson.

Practice this safely

Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.

1. 1Ask AI to explain tool design in plain language, then underline anything that sounds uncertain or too broad.
2. 2Give it one detail from "Designing the Toolbox You Hand Your Agent" and ask for two possible next steps plus one reason each step might be wrong.
3. 3Check scope against a trusted source, teacher, adult, expert, or original document before you use it.
