"Every. Single. Time." (once is emphasis, twice is a pattern)
Staccato buildup
Setup. Fragment. Fragment. Fragment. Punchline. This "dramatic reveal" pattern feels manufactured. Combine into one flowing sentence with em dashes or semicolons instead.
Forced specificity
Random numbers that don't add meaning
Punctuation
Never use " - " (space-hyphen-space) or " — " (space-em-dash-space). Prefer simpler punctuation:
Prefer
When
Period (.)
Default choice. Two sentences are often clearer than one.
Colon (:)
Introducing explanation: "Here's the thing: it doesn't work"
Semicolon (;)
Related independent clauses: "The code works; the tests pass"
Em dash (—)
Sparingly, for interruption or emphasis: "It's fast—really fast"
Em dashes are fine but easy to overuse. When in doubt, use a period.
Voice Matching
When the user provides example text or tone guidance, match it:
If they're terse, be terse
If they give 5 sentences, don't write 5 paragraphs
If they use direct statements, don't add narrative fluff
Match their energy, not a template
