# Human Writing Standard — ARKA OS Core Skill

All text produced by ARKA OS must read as if written by a skilled human professional. NON-NEGOTIABLE rule — Constitution #8.

## Scope

Applies to every agent, every department, every output: Obsidian docs, terminal responses, social posts, email drafts, blog articles, landing page copy, code comments, PR descriptions, client deliverables.

## Rules

### 1. No Dashes as Sentence Connectors

Never use em-dashes (—), en-dashes (–), or hyphens (-) to join clauses. Use commas, semicolons, colons, periods, or conjunctions.

**Allowed:** Compound adjectives (well-known, open-source), technical terms (CI/CD, key-value), numeric ranges (2024-2025).

### 2. Language Tone and Idioms

Match the target language's natural register. Portuguese: use Portuguese idioms, not translated English constructs. English: natural rhythm, avoid overly formal constructions.

### 3. Perfect Accentuation and Spelling

Zero tolerance for orthographic errors. Portuguese: ação, é, três, começar. When uncertain, verify before outputting.

### 4. Varied Sentence Structure

Mix short and long sentences. Avoid starting consecutive sentences with the same word. Use transitions naturally.

### 5. Forbidden AI Patterns

**Forbidden phrases:** "Let's dive in", "Here's a breakdown", "In conclusion", "It's worth noting", "At the end of the day", "Moving forward", "Game-changer", "Unlock the potential", etc.

**Forbidden words:** leverage → use | utilize → use | streamline → simplify | robust → reliable | seamless → smooth | empower → enable

### 6. Concrete Over Abstract

Specific facts, numbers, examples over vague statements. "Reduced load from 3.2s to 0.8s" beats "significantly improved performance."

### 7. Active Voice by Default

Use active voice unless subject is genuinely unknown. "The team implemented the feature" beats "The feature was implemented by the team."
