wtf is clean-writing?

Clean writing is a skill for Claude Code and Claude Desktop that teaches the AI assistant to write and revise prose in one consistent house style, instead of whatever style it would normally default to. It is a folder of markdown instructions that Claude reads automatically before drafting or editing documents, READMEs, emails, or pull request descriptions. The skill combines three separate sources of guidance. The first is Canadian conventions for things like money, dates, times, spelling, and number ranges. The second is a set of the author's own personal style rules, such as never using dashes, allowing negative contractions, and using the Oxford comma. The third is the complete Google developer documentation style guide, which the author gathered in full and organized into reference files covering tone, grammar, punctuation, formatting, and how to describe code within prose. When these three sources disagree with each other, Canadian convention takes priority first, followed by the author's own rulings, with Google's guidance filling in whatever is left. The project explains that each of these three layers alone leaves gaps. Plain, simple writing alone does not say how to format a table or punctuate a list. A detailed style guide alone often reads in a dense, bureaucratic voice. And regional convention alone only settles small details like date formats and spelling, not sentence structure or tone. Installing the skill can be done in three ways: through a community tool called skills, which automatically fetches and places public GitHub skills into the correct folder, by cloning the repository directly into a personal or project specific Claude Code skills folder, or by adding it through Claude Desktop's built in Skills panel using its GitHub path. Once installed, the skill applies automatically whenever Claude is asked to write, though it can also be triggered directly by name. It is released under the MIT license.
