The tell is rarely a word. It is a sentence doing no work.

> add skill humanizer

Most cleanup tools swap vocabulary and leave the shape alone, which makes the writing harder to spot without making it better. The interesting version of this deletes the parts that would be equally true of any other subject.

Galley proofNot output from the skill

It is worth noting that ^ the parser was built with careful consideration ^ to handle files of all shapes and sizes ^ that arrive from upstream.

after the marks are applied

The parser handles files that arrive from upstream.

margin marks

filler openerDelete. The clause announces a statement instead of making one.

empty modifierDelete. It describes effort rather than behaviour, and no reader can check it.

unbounded scopeDelete or name the range. All shapes and sizes claims a limit nobody measured.

what the cuts have in common each would be true of any parser the skill's own rule list is not published

Removing is the verb

The description says removes rather than rewrites, which sets the expectation that the tool subtracts and leaves your sentence rather than producing a new one in its own voice.

Signs is the plural that matters

A single tell can be an accident. A set of them together is what makes a page read as machine written, so the useful unit of work is the paragraph.

What is not on this page

No rule list, no pattern count, no before and after corpus, no accuracy figure. The trending description is one line and names none of it.

Concept mock, not affiliated with the project. The complete GitHub Trending description on 3 September 2026 is "Agent skill that removes signs of AI-generated writing from text." The marked-up paragraph and the three margin marks were written for this page to show what the category means; they are not output from the skill and they do not represent its rule set, which the description does not publish.
