Write A Checkable Task Question Explained
This worked Loop Engineering practice question tests Checkable Tasks. Try the answer first, then review why D is the best choice.
Short answer
The correct answer is D. Show Espresso at $3, Latte at $4, and Tea at $2 on the menu in index.html.
A task the loop can finish names what should change and where it should appear. Three prices in one named file can be compared against the page after the run. "Improve" has no end state. The agent can make a small change and mark the task done, and the check has nothing concrete to test. The correct answer is D. Show Espresso at $3, Latte at $4, and Tea at $2 on the menu in index.html
The Question
Your loop marked the task "Improve the coffee shop website" as done. The page looks almost the same. Which rewrite gives the loop a result it can finish and check?
Why D is correct
A task the loop can finish names what should change and where it should appear. Three prices in one named file can be compared against the page after the run. "Improve" has no end state. The agent can make a small change and mark the task done, and the check has nothing concrete to test. The correct answer is D. Show Espresso at $3, Latte at $4, and Tea at $2 on the menu in index.html
Why the other options are wrong
Naming the file helps, but "cleaner" and "more professional" have no end state. The agent can stop after any change, and the check has nothing to compare.
Handing over judgment removes the check. You cannot compare the page to a task that never said what the page should contain.
A role description sets a style, not a result. Two runs would do two different things and both would look done.
Key idea: Checkable Tasks
Loop engineering is a practice skill. Open Claude Code in a throwaway folder, write one small task in a file, and run it with /loop or /goal while you watch. If you doubt an answer, test it against a real run in that folder.
