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
