Prompt Cleanup Examples (Before & After)
A set of before-and-after examples showing exactly what prompt cleanup removes — and what it deliberately leaves alone.
Fix Conflicting Instructions in a Prompt
How to surface contradictions like 'keep it short' and 'be highly detailed' that quietly produce inconsistent AI output.
Overview
The hardest prompt problems are not typos — they are contradictions. A prompt that says 'keep the answer short' in one line and 'provide a highly detailed response' in another will produce unpredictable output, because the model has to guess which one you meant. These conflicts are easy to miss in a long prompt. This resource shows how the Prompt Cleaner detects opposing instructions and flags both sides so you can decide which one to keep.
How to use this resource
-
Paste the prompt
Load the prompt you suspect has conflicting instructions into the input.
-
Clean and open the report
Run any mode, then open the Cleanup Report tab. Detected contradictions are listed with both conflicting lines.
-
Decide which instruction wins
For each flagged conflict, pick the instruction you actually want and remove the other from your prompt.
-
Re-clean to confirm
Run the cleaner again on the corrected prompt — the contradiction should no longer appear.
Why This Works
- Catching a contradiction before you run the prompt is far cheaper than diagnosing it from confusing output afterward
- Showing both conflicting lines, rather than auto-resolving, respects that either could be the one you meant
- Conflicts in length and tone are the most common and the most damaging — they change the entire shape of the response
Best for
- Prompts that produce unpredictable results you can't explain from the input
- Prompts where length, tone, or example instructions may have drifted out of agreement
- Long prompts where conflicts are too far apart to spot by eye
Not for
- Resolving the conflict automatically — the cleaner flags both sides but leaves the choice to you
- Prompts with intentional conditional instructions (do X in case A, Y in case B)
Use cases
- Auditing a prompt that produces inconsistent output for hidden contradictions
- Reviewing a prompt assembled from several people's edits before running it
- Checking a long system prompt for conflicting length or tone instructions
FAQ
How do I find contradictory instructions hidden in a long prompt?
Paste the prompt into the Prompt Cleaner, run any mode, then open the Cleanup Report tab. It lists each detected contradiction with both conflicting lines shown side by side, so pairs like 'Include examples' and 'Do not include any examples' surface even when they sit far apart in a long system prompt you'd never catch by eye.
How is a 'keep it short' versus 'be detailed' conflict handled in the report?
It pairs the two opposing lines and shows both in the Cleanup Report, so 'Keep the answer short and concise' appears right next to 'Provide a highly detailed, comprehensive response'. The report doesn't grade or rank them — it just puts the pair in front of you so you can spot which line you actually meant and cut the one that slipped in during editing.
Will the cleaner decide which conflicting instruction to keep for me?
It flags both sides and leaves the pick to you — it stops at 'Be friendly and casual' versus 'Maintain a formal, professional tone' without deciding a winner. So a conflict only clears once you delete one line yourself and re-run the cleaner. Watch out with deliberate conditional rules (do X in case A, Y in case B) — it can flag those as clashes too.
