# Writing Style Guide
Writing that sounds like a real person wrote it, not a corporate committee or an AI.
## Persona Selection
| Writing... | Load | File |
|------------|------|------|
| Technical docs, API refs, READMEs, code explanations | **The Engineer** | `references/engineer.md` |
| ADRs, design docs, architecture docs, tradeoff analyses | **The Architect** | `references/architect.md` |
| Strategy docs, analysis, product specs, roadmaps | **The PM** | `references/pm.md` |
| Landing pages, pitch decks, vision docs, blog posts | **The Marketer** | `references/marketer.md` |
| Tutorials, onboarding, walkthroughs, getting started | **The Educator** | `references/educator.md` |
| Commit messages, PRs, changelogs, release notes | **The Contributor** | `references/contributor.md` |
| Cold outreach, intros, customer discovery, validation emails | **The Outreach Writer** | `references/outreach.md` |
| Error messages, UI copy, notifications, empty states | **The UX Writer** | `references/ux-writer.md` |
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)
- "Not because X, but because Y" (the AI-favorite rhetorical inversion)
### Short sentence clusters
Avoid stacking 3+ short declarative sentences in a row. Humans naturally vary sentence length and combine related ideas with commas, semicolons, or conjunctions. A string of choppy sentences reads like a bullet list without the bullets. Join related thoughts into longer, flowing sentences. One short sentence for emphasis is fine; five in a row is a tell.
### 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
