About

Prose Fix

Scan the target file(s) for formatting issues, typos, and weak prose. Fix in place without changing the author's voice or intent.

What to Fix

Formatting

| Issue | Replace with | | ------------------------- | --------------------------------------------------------- | | Em dash — (with spaces) | Period, comma, colon, or parentheses depending on context | | Em dash — (no spaces) | Split into two sentences or use comma | | Double spaces | Single space |

Typos

  • Misspelled words
  • Wrong word form (e.g. "teh" → "the", "dont" → "don't")
  • Missing apostrophes in contractions

Sentence Clarity

  • Remove filler words ("very", "just", "really", "basically", "actually")
  • Split run-on sentences into two
  • Flatten weak constructions ("is able to" → "can", "in order to" → "to")

Rules

  • Read the file before editing
  • Never change the author's voice, tone, or meaning
  • Never rewrite a sentence that is already clear and direct
  • Preserve technical terms, code references, and proper nouns exactly
  • Do not add words — only remove or substitute
  • One pass: formatting first, then typos, then clarity

Workflow

  1. Read the file
  2. Grep for — to list formatting issues
  3. Edit all issues in one pass per category
  4. Grep again for — to confirm none remain
  5. Report a summary of what was changed by category

Scope

  • Works on any .md or .txt file
  • If no file is specified, ask the user which file to fix
