TL;DR:
Small steps are easier to do, to check and to undo than one big step.
Each step should have a visible result you can check in under a minute.
Put checkpoints where a mistake would be costly, and let the cheap steps run on their own.
"Prepare the monthly report" is a perfectly good instruction for a colleague who has done it before. For an agent, it is a mountain: a hundred small decisions packed into a sentence. When a big job goes wrong, it is hard to tell where, and hard to fix without starting over. The remedy is old advice that still works: break it down.
Here is a monthly report split into five steps, with the reasoning for how it was cut.
What makes a good step
One clear action. "Export the sales numbers" is a step. "Handle the data" is not.
A visible result. A file exists, a cell has a value, a page shows a figure.
A quick check. You can judge in under a minute whether it worked.
Independent enough to redo. If it fails, you can repeat it without redoing earlier work.
Walk-through: a monthly report split into five steps
The report: a one-page summary of last month's sales for the team, built from a dashboard and a sheet.
1. Export the data: Export last month's sales from the dashboard as a file. Result: a file named with the month. Check: the date range in the file matches last month.
2. Load it into the sheet: Paste the rows into the "Raw" tab. Result: the Raw tab has the rows. Check: the row count matches the export.
3. Update the summary: Refresh the summary tab, which uses formulas over Raw. Result: new totals. Check: the grand total equals the sum of the raw sales column.
4. Draft the one-page text: Write three sentences using only figures from the summary tab. Result: a draft. Check: each number in the text appears in the sheet.
5. Stop for approval, then send: Show you the draft and wait. Only after you say yes does it send. Result: the message goes out once.
Each step ends in something you can see, and none depends on the agent's memory of earlier ones: the file, the tab and the draft are all there to inspect. If step 3 gives a wrong total, you rerun step 3, not the whole job.
Where to put checkpoints
A checkpoint is a pause where the agent shows you its progress and waits. Too many and you might as well do it yourself. Too few and a mistake travels downstream. A good rule: put one before anything hard to undo, and one after any step that transforms data.
In the example, the checkpoints are after step 3, where the numbers are settled, and before step 5, where the report leaves your hands. Steps 1, 2 and 4 are easy to check later and cheap to redo.
Hand-off values
Name the things that pass from one step to the next. Step 1 produces "the March export file". Step 2 uses that file by name. If the agent has to remember "the file from before", it can pick the wrong one. Explicit names make each step self-contained, which makes the whole job restartable from the middle.
Note: If a step cannot be checked, split it further or add a way to see its result. A hidden step is where a hidden mistake lives.
How big should a step be
Big enough to be worth checking, small enough to be obvious. A useful test: can you describe what success looks like in one sentence? "The Raw tab has 214 rows, matching the export" is one sentence (with an example count). "The data is processed" is not.
Reordering for safety
When you split a job, you also choose the order. Put the reversible, read-only steps first and the irreversible ones last. Exporting and reading change nothing, so they can happen early. Sending changes the world, so it goes at the end, behind a checkpoint. If the job fails at step 3, nothing outside your own files has changed, and you can simply try again.
A second ordering rule is to do the riskiest uncertainty early. If step 4 depends on a figure that might not exist, find that out in step 1, not after three steps of work.
What this does not fix
Small steps reduce risk but do not remove it. A step can still misread a page, and a clean-looking result can hide a wrong number. Your checks are the safety net, so make them real, with a count, a total or a visible change, rather than a glance.
Privacy and control
Break the job so that the steps touching sensitive things, like sending or sharing, come last and wait for you. DuckyHelper's agent features are early access. It's built to ask first before it sends a message or pays for anything, and not to type your passwords or card numbers.
Try it yourself
Take a task you do monthly and write the steps on a card, with the result and check for each. Then mark which two steps most deserve a pause. That card is the instruction you would give an agent, and it is also a good checklist for yourself.
Frequently asked questions
Is it slower to use many small steps?
Slightly, but you save the time lost to mistakes you find late.
Should every step have a checkpoint?
No. Pause where mistakes are costly or hard to undo. Let cheap steps run.
What if a step fails halfway?
Because each step stands alone, rerun just that step after fixing the cause.
