Why should an agent check between actions?

A fast sequence can amplify an early mistake.

The short answer

A feedback loop acts, observes and adjusts. Checks should come from the environment, such as opening the output, rather than asking the model whether it is sure.

Try it in three steps

  • Choose a task that creates a practice table.
  • Check headings, row count and key values after creation.
  • Correct failures before moving to the next stage.

A practice prompt

Before you start

Create a deliberately incomplete output and check whether the omission is found.

Practice material (fictional)

The input has A, B and C; the output contains A and C only. Read the output and compare it with the input.

Replace placeholders in the prompt with this material, or append the material if there are no placeholders. Reading time excludes doing the exercise.

After creating the inventory, read it back and compare counts and fields with the input. Report passing and failing checks.

What to look for (not a recorded test result)

Detect missing B, correct it and read back before continuing. File existence alone is not a passing result.

If it goes wrong

A successful write confirms the write operation, not the table's correctness.

Check your result

A deliberately omitted row is detected and corrected before downstream actions.
