ruthless-editor: every sentence earns its place
First drafts explain themselves to their author. The cutting pass is where writing starts serving the reader. Models pad by default - hedges, throat-clearing, summaries of what was just said, adjectives doing no work. This skill is the antidote, run as a separate pass AFTER drafting.
The pass
Take the draft. For every sentence ask, in order:
- Does the reader need this to act or decide? No: cut.
- Does it repeat something already said? Restated intros, "in summary" paragraphs that add nothing, the same caveat twice: cut the weaker instance.
- Is it hedging without information? "It's worth noting that", "generally speaking", "as you may know": cut the frame, keep the fact.
- Is it abstract where it could be concrete? "significant performance improvement" becomes "dropped from 2.1s to 340ms". If you do not have the number, say what you do have. Concrete survives, abstract gets cut.
- Is the sentence doing two jobs? Split it or pick the job that matters.
Then the structural cuts:
- Lead with the outcome. The first sentence answers "what happened" or "what should I do". Background comes after, for whoever wants it.
- Kill the throat-clearing intro. If the first paragraph could open any document on the topic, it opens none. Delete it and check that nothing is lost. Nothing ever is.
- One idea per paragraph, and the idea in the first line. Readers scan. Reward the scan.
- Banned without exception: filler superlatives (seamless, powerful, robust, cutting-edge, game-changing), empty transitions (moreover, furthermore as sentence glue), unearned "simply" and "just".
The 30 percent test
Count what you cut. Under 20 percent on a first draft means the pass was timid - go again. If cutting genuinely loses information, the draft was already tight (rare) or you cut facts instead of fat (check which).
What ruthless does NOT mean
- Not terse to the point of rudeness or ambiguity. Clarity outranks brevity - a short confusing sentence loses to a longer clear one.
- Not stripping the reader's necessary context. The test is "does the READER need it", not "do I find it obvious".
- Not compressing into fragments and jargon chains. Complete sentences, technical terms spelled out on first use.
The tell
If a sentence needs to be defended with "but it sounds professional", it is padding. Professional IS the absence of padding.
