Individual skill

lossless-doc-compress

Use when asked to compress, tighten, shorten, condense, or de-slop a design doc, PRD, RFC, architecture note, or similar prose "without losing information". Removes only provable redundancy — filler, hedging, LLM-slop, restated content — never a fact, number, decision, or caveat, and flags every judgment call for the author. Returns a compressed document, a categorized removal log, and a shareable scorecard.

# Lossless Doc Compress

Use this skill to make a design document shorter without making it say less. The useful
output is not a summary. It is the same document with the filler, hedging, slop, and
repetition removed, plus an honest account of exactly what was cut and what the author
should decide for themselves.

This skill is a sibling of `ml-system-design-review` and `ai-stage-gate` in the same
[ML System Design](https://arseny.info/ml_design_book) skill collection by Kravchenko and
Babushkin: **`ml-system-design-review` grades substance; `ai-stage-gate` decides
Go/Kill; `lossless-doc-compress` trims length without touching substance.**

It encodes a simple, well-worn piece of advice: an LLM-written draft is fine *if* the
author read it, corrected it, and gave it context — that is delegating the editing, not
