Enforce the writing style in code

How to do it

Strip code from each page's text and check it. Each sentence has at most 25 words, with no semicolons and no banned jargon. A colon never sits between a sentence and an inline list. Headings never join a fragment with a comma, and a measured change always says where it started. Check the visible HTML too, not only the Markdown. Give each rule tests with words it must allow and words it must catch. A pattern for one banned word can block a correct word that starts the same way.

Example

// One of the writing checks: sentences of at most 25 words
const sentences = text.split(/(?<=[.!?])\s+/);
for (const s of sentences) {
  const words = s.split(/\s+/).length;
  if (words > 25) problems.push(`${words} words (max 25): "${s}"`);
}

# The same check in Python
for sentence in re.split(r"(?<=[.!?])\s+", text):
    words = len(sentence.split())
    if words > 25:
        problems.append(f'{words} words (max 25): "{sentence}"')

How to check

Add a 30-word sentence or a semicolon to any page. The build stops and quotes the sentence.
