wtf is write-better?

write-better is a skill that agents like Claude Code or Codex can install to help them write clearer, more direct prose that reads naturally, rather than in a stiff or generic AI voice. It is meant to apply broadly, covering new drafts as well as edits to documentation, workplace messages, essays, reports, explanations, and the short copy used inside an app's interface. Once installed, a user or agent invokes it by name, using the command write-better, whenever they want an AI agent to draft, rewrite, edit, or review a piece of writing for clarity, usefulness, tone, and a natural human sounding voice. The goal stated in the README is prose that does not invent facts and does not flatten the author's own voice into something generic. The guidance behind the skill draws on ideas from what the author calls the Humanizer pattern catalog, along with Wikipedia's page describing common signs of AI generated writing, using both as reference points for what to avoid. Installation is done through the skills command line tool with npx skills add plannotator/write-better, and the README notes you can list the available skill before installing it. There are also dedicated installation paths for Claude Code, added as a plugin marketplace entry, and for Codex, using its own plugin marketplace command. The project is released under the MIT license. Beyond the install commands and this general description, the README does not go into further detail about how the skill's internal rules are structured or what specific rewriting techniques it applies.
