# 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`   |
| Reddit replies, forum comments, casual DMs, social replies   | **The Poster**          | `references/poster.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
