Make Terminal Output Your Shared Truth
Do not argue with the agent about what happened. Paste the exact command and output so both of you reason from the same evidence.
Name the job before naming the tool.
Write the smallest useful scope the agent can finish.
Run the result as a user, not as a fan of the tool.
Inspect the diff, data access, and failure path before sharing.
Run npm test. Paste the first failing test name, stack trace, and command. Ask the agent to fix only that failure.Use this as the working prompt or checklist for the lesson.
What should the user be able to do when this is finished?
What data should the app or agent never expose?
What test proves the change works?
What rollback path exists if the output is wrong?

When an AI agent's code doesn't work as expected, what is the most effective way to get help?
Share a screenshot of the entire terminal window
Run the code again and hope for a different result
Describe what you think went wrong in your own words
Paste the exact error message and the command that produced it
A developer tells an AI agent: 'I want you to write a Python script that fetches data from an API.' Which approach follows the lesson's advice about naming the job before the tool?
Tell the agent to use whatever tool works best
State what the finished script should accomplish (e.g., 'fetch user data from the API and save it to a CSV file')
Ask the agent to use the most popular Python library
Immediately specify which library to use (requests, httpx, etc.)
Why does the lesson advise writing the 'smallest useful scope' when working with an AI agent?
Smaller scopes are easier for the agent to complete correctly on the first attempt
The lesson prefers boring, simple projects
Smaller scopes cost less money to run
AI agents cannot handle complex tasks
What does it mean to 'run the result as a user, not as a fan of the tool'?
Avoid criticizing the tool's performance
Only use tools made by companies you admire
Support the tool developer's intentions regardless of output
Test the code as if you were a real person using it, not testing whether the tool itself works
Before sharing AI-generated code with others, the lesson says you should inspect three things. Which trio is correct?
The syntax, color scheme, and variable names
The diff (changes), data access, and failure path
The cost, the popularity, and the license
The AI's confidence level, the date, and the developer
When asking an AI for help with broken code, you should answer four questions beforehand. Which question is NOT listed in the lesson?
What data should the app never expose?
What test proves the change works?
What rollback path exists if the output is wrong?
What programming language should I use?
A developer pastes this to an AI: 'build failed.' Why does the lesson consider this unhelpful?
The AI will get confused by too much information
The AI cannot read text that short
Build failures are not important to debug
It removes the specific line numbers and error patterns the AI needs to diagnose the problem
What makes terminal output a 'shared truth' between a developer and an AI agent?
It's required by law
It's objective evidence both parties can reference rather than subjective interpretation
It's the only thing the AI can read
Developers must believe whatever the terminal shows
The lesson says AI can make a working demo quickly, but 'real skill' is turning that demo into something that is:
Observable, reversible, and safe enough for another person to use
Complex, impressive, and novel
Colorful, interactive, and documented
Fast, cheap, and popular
Why is it important to have a 'rollback path' before running AI-generated code?
Because AI always makes mistakes
So you can return to a working state if the new code causes problems
The lesson says AI code is dangerous
Rollback paths are required by IT departments
A developer gives an AI agent a massive, complex task all at once. How would the lesson describe this approach?
AI agents prefer complex, detailed tasks
It's the most efficient way to get results
Complex tasks show the developer is serious
It increases the chance the agent will misunderstand requirements and produce errors
When debugging with an AI agent, why should you avoid describing what you 'think' happened?
Thinking is not allowed while debugging
AI agents can't understand opinions
The lesson prefers silent debugging
Your interpretation might be wrong and guide the agent toward the wrong solution
What does the lesson mean by saying terminal output should be your 'shared truth'?
Terminal output is the only truth in programming
You should only trust output from the terminal
The terminal is always correct about everything
Both you and the AI should reference the same objective output rather than arguing about interpretations
If an AI agent produces code that works but you're unsure what it does, what should you do before using it?
Delete it and start over
Inspect the diff, understand the data access, and trace the failure path
Trust that it works since the AI is smart
Use it immediately since testing takes too long
The lesson mentions 'observable, reversible, and safe' as criteria for turning an AI demo into something ready for others. What does 'observable' mean in this context?
The code has a graphical interface
You can see what's happening inside the code—logs, outputs, and behavior are visible
