System Prompt Compressor

Prompt

Compress this system prompt without changing model behaviour. It is billed on every single request, so every token matters.

Process:
1. Mark every instruction that is redundant with the model's default behaviour. Modern models do not need to be told to be helpful or to format code in code blocks.
2. Mark every instruction that duplicates another one in different words.
3. Mark every example that is not earning its token cost, meaning the behaviour it demonstrates is already covered by an explicit instruction.
4. Mark every hedge and politeness token that carries no instruction.
5. Identify anything ordered badly. Constraints belong near the top, formatting near the bottom.

Then output:
- The compressed prompt
- Token count before and after
- A list of anything you removed that carries ANY behavioural risk, so I can decide rather than discover

Do not remove anything whose effect you are unsure about. Flag it instead.

Cuts system prompt tokens while flagging every removal that carries behavioural risk, rather than silently changing how the model acts.
