Debugging prompt compression

When compression removes content that should have been kept, debugging can be tricky. Here is a systematic approach to verify compressed outputs.

Debugging workflow

  1. Check the compression ratio — If the ratio is unusually high (90%+), compression may be too aggressive
  2. Review the compressed text — Does it contain the key facts needed for the answer?
  3. Check oracle recall — Run the compressed and original versions against a known answer
  4. Compare token distributions — Are important sections being disproportionately removed?

Frequently asked questions

How do I find what was incorrectly removed?

Compare the original and compressed text line by line. The removed lines that should have been kept are your false positives.

Can I log every compression decision?

Yes. SuperCompress returns which lines were kept and removed. Log these for debugging.
