Cuts a draft to a target word count without losing substance. Two modes behind one skill. target-count hits a specific number (200 for a cold email, 500 for an op-ed, 6 for a product summary). redundancy catches the specific failure where a phrase says what the verb or context already implied — "going forward" after a future-tense verb, "as I mentioned earlier," "reduce so they are smaller." Implements Kramon's "rewrite this in less than 100 words" exercise, the six-word summary drill, and the…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Compression

Source: `points/core-rules.md` rule 5 (be shorter), `points/banned-jargon.md` (wordy phrases), `points/frameworks.md` (six-word summary), and the Kramon in-class redundancy exercise.

> *"Be shorter. Always. Cut without losing substance."* — Kramon

## What this skill does

Two modes behind one skill. They cut different things:

| Mode | Cuts | Use when |
|---|---|---|
| **target-count** | throat-clearing, hedges, weak sentences, anything between the draft and the word target | User has a length to hit (200 for cold email, 500 for op-ed, 6 for product summary) |
| **redundancy** | phrases where one half is implied by the other (`going forward`, `as I mentioned`, `reduce so they are smaller`, `free gift`, `definitely commit`) | Draft is wordy in a way that's hard to point at — long without obvious filler |

Default `--mode both` runs redundancy first (it's surgical, every cut is defensible), then target-count (which may need to cut substantive material). The order matters: redundancy cuts free words first, so target-count doesn't have to.

## How to invoke

```
/compression "draft text"
/compression --mode target-count --target-words 200 "draft text"

How to install

The exact contents, by fingerprint
mdr add kalyvask/winning-writing/compression@sha256:d55f4c80c8c5925a

The line at the top of this page pins the label git:20260524.5bb6ce8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
