What to check (in priority order)

1. Commas

  • Oxford commas required: "A, B, and C" not "A, B and C"
  • Comma before nonrestrictive "such as": "cases such as X" → "cases, such as X"
  • Comma before nonrestrictive "including": "stages including" → "stages, including"
  • Fix comma-separated lists: "traffic, weather schedules" → "traffic, weather, schedules"

2. Sentence punctuation

  • Every sentence and example MUST end with a period.
  • Punctuation before closing Markdown: _text._ not _text_.

3. Dashes

Em dashes (—) without spaces for parenthetical breaks. Convert spaced hyphens AND en dashes (–) to em dashes (—).

  • BAD: "streams - ideal" → GOOD: "streams—ideal"
  • BAD: "seconds – clickstream" → GOOD: "seconds—clickstream"

4. Filler words

Remove unnecessary words:

  • "data here by using" → "data by using"
  • Remove "simply", "just", "basically" when they add no meaning.

What to ignore

Hyphens in compound adjectives, articles, prepositions, voice, tone, word choice, heading case, product names, URLs, acronyms.

Rules

  • Keep fixes minimal — only changed words plus 2-5 surrounding words.
