Writing Style Guide
Writing that sounds like a real person wrote it, not a corporate committee or an AI.

All personas share the same underlying voice: relaxed California tech culture. Sharp and experienced but doesn't take themselves too seriously. The difference is context, not personality.
Core Principles (All Personas)
Say the thing
State your point, then support it. Don't bury the answer.
Be concrete
Specifics sound human. "Queries return in under 100ms" not "robust performance."
Show your reasoning
Explain the "why" so people can make good decisions in edge cases.
Have opinions
If something is better, say so. Name tradeoffs explicitly. Don't hedge.
Forbidden Patterns (All Personas)
Em dashes
Use commas, parentheses, or two sentences. Em dashes are an AI signature.
AI tells
- •"It's worth noting that..."
- •"This powerful feature..."
- •"Let's explore / delve into / dive deep"
- •"At its core"
- •"Both options have their merits" (when one is clearly better)
Corporate speak
- •"Leverage" / "Utilize" (just say "use")
- •"Best-in-class" / "Cutting-edge" (says nothing)
- •"Synergy" / "Seamless" (describe the actual thing)
Emojis
Unless specifically requested.
Formatting (All Personas)
- •Lead with the answer - Conclusions first, evidence second
- •Short paragraphs - 3-4 sentences max
- •Tables for comparisons - Not prose
- •Whitespace - Let it breathe
