A workflow can produce a beautiful report and still leave you with more work. Test the result against the job you needed done, including the time it takes to check and repair it.
The first successful run is encouraging. It is also one run, on one piece of material, under one set of conditions. Before moving an entire manuscript into a new process, give that process a small trial with an outcome you can actually inspect.
Choose one question
“Does this editing workflow work?” is too broad. Try “Does this continuity check catch changes in what a character knows without flagging intentional uncertainty?” The narrower question tells you what evidence to collect and what a failure looks like.
Write down the intended result before running the test. Otherwise, it is easy to admire whichever result appears. If the job is finding continuity errors, a polished summary of the chapter is not a successful substitute.
Keep a small reference set
Use material you know well and have permission to use. Include a straightforward passage, a difficult passage, and a passage that should be left alone. Preserve the originals so every version of the workflow sees the same starting material.
For a continuity trial, you might create a separate test copy containing a deliberate contradiction. Label that copy clearly so it cannot find its way into the manuscript. Write down the planted issue and its location before asking the assistant to examine it.
Do not rely entirely on planted mistakes. They can be cleaner than the problems that occur naturally in fiction. Include a real passage with ambiguity, and record what you believe is intentional. The workflow needs to handle both defects and artistic choices.
Record enough to repeat the trial
Save the instructions, input files, tool or model name as displayed, date, and relevant settings. Keep the actual output, not just your impression of it. If you revise the instructions, save that version too.
These records do not need a complicated dashboard. A folder with numbered runs and a short notes file can be enough. The important part is being able to distinguish a change in the workflow from a change in the material it received.
Judge the work, including the cleanup
Look for useful findings, missed problems, unsupported findings, and changes that violate your instructions. Check every quoted passage against the source. A precise-looking citation is only useful when it points to words that are actually there.
Also note the effort required to use the answer. Did you spend ten minutes checking a result that saved two minutes? Did the output make the next decision easier? Did you have to reconstruct information the workflow was supposed to preserve? Your attention is part of the cost.
Change one thing you can explain
Hypothetical example: A continuity checker flags a character’s deliberate lie as a factual contradiction. Revise the brief to distinguish narration, dialogue, and confirmed story facts. Run the same reference set again and compare both the original problem and the passages that previously worked.
A repair that fixes one case but creates several new mistakes is useful information. Resist adjusting the entire system after every disappointing answer. Make a targeted change, then look for evidence that the change helped.
Decide what the workflow has earned
Repeat a few representative cases to see whether the behavior is stable enough for the intended job. Keep the conclusion modest: this workflow helped with this task on this material. A successful scene check does not establish that it can safely revise a whole series.
Expand gradually, preserve checkpoints, and keep human review where a mistake would be expensive. Trust becomes more useful when it has a scope. You should be able to name what the workflow does reliably, what still needs inspection, and when to stop using it.
