Prompt Cleanup Examples (Before & After)
A set of before-and-after examples showing exactly what prompt cleanup removes — and what it deliberately leaves alone.
Remove Repetition from a Prompt
A worked example of stripping duplicate and restated instructions out of a prompt that says the same thing five different ways.
Overview
Repetition creeps into prompts the same way it creeps into writing: you restate an instruction to be safe, then restate it again later, and a third time in different words. The model doesn't read repetition as emphasis — it reads it as more instructions to weigh, which dilutes the ones that matter. This resource shows how to collapse 'be professional / maintain a professional tone / keep it professional' down to a single instruction, using the Prompt Cleaner's Balanced mode.
How to use this resource
-
Paste the repetitive prompt
Load this example or your own prompt into the Prompt Cleaner input.
-
Run Balanced Clean
Balanced mode collapses restated instructions that mean the same thing, keeping the first occurrence of each distinct idea.
-
Read the Cleanup Report
The report shows how many repeated instructions were removed and the reduction percentage.
-
Confirm in Before / After
Check the side-by-side view to make sure every distinct instruction survived before copying the result.
Why This Works
- Models weigh every instruction — three professional-tone statements compete with the rest of the prompt instead of reinforcing each other
- Keeping the first occurrence of each idea preserves your intent while removing the noise around it
- A shorter prompt with no repetition leaves more of the context window for the actual content the model has to work with
Best for
- Prompts edited by several people, each adding their own version of an existing instruction
- System prompts that grew by appending reminders instead of revising
- Any prompt where the same idea appears more than once in different words
Not for
- Prompts where each instruction is genuinely distinct — there is nothing to collapse
- Rewriting or improving instructions — the cleaner only removes, it does not reword
Use cases
- Cleaning a prompt where the same role was declared in two or three different sentences
- Collapsing repeated tone instructions that accumulated as the prompt was edited
- Trimming a prompt before pasting it into a model with a tight context window
FAQ
Why use Balanced mode instead of a heavier clean on this marketing-consultant prompt?
Balanced mode only collapses lines that mean the same thing and keeps the first wording of each distinct idea, so these nine lines fold to three: one role, one 'detailed recommendations', one professional-tone line. It drops the duplicate 'act as a senior marketing consultant' and the four detail restatements without rewording anything, which suits a pure de-duplication job better than a rewrite-oriented pass.
When two role lines say almost the same thing, which one does the cleaner keep?
It keeps the first occurrence, so 'You are an expert marketing consultant with years of experience' survives and the later 'Please act as a senior marketing consultant' is dropped. If you actually preferred the 'senior' phrasing, reorder the prompt so your preferred wording comes first before running it, or edit the result in the Before / After view. The cleaner removes; it does not choose better wording for you.
How can I confirm the four 'detailed' instructions collapsed without losing a real requirement?
Collapsing 'Provide detailed recommendations', 'Provide comprehensive, in-depth recommendations', 'Give detailed advice', and 'Make your recommendations detailed' into one line is safe here because all four ask for the same thing. Scan the side-by-side Before / After to confirm a genuinely separate instruction like 'Be professional' still stands on its own; the Cleanup Report's removed count is your second signal before you copy the result out.
