Contains well-defined rules for creating natural, accurate, and readable writing. Use whenever authoring longer text, like analysis documents, PR or CL descriptions, or documentation.

🧩 One of 7 skills in the flutter/skills package — works on its own, and pairs well with its siblings.

This is the playbook your agent receives when the skill activates — you don't need to read it to use the skill, but it's here to audit before installing.

Rules for Natural Writing

This document outlines strict rules to avoid common "AI-isms"—stylistic and structural patterns that language models typically fall into. Follow these rules to produce content that is more understandable, and reads as natural, human-authored text.

1. Vocabulary & Phrasing Controls

The "Banned" List

Avoid these words, which are statistically overrepresented in AI text. Use simpler, more direct alternatives.

  • Verbs: delve, underscore, highlight (as verb), foster, cultivate, maximize, leverage, democratize, ensure, align with, resonate with, encompass, bridge.
  • Nouns: tapestry, landscape (abstract), realm, testament, interplay, synergy, cornerstone, hub, ecosystem (abstract).
  • Adjectives: pivotal, crucial, vibrant, intricate, nuanced, unwavering, indelible, uncharted, rapidly evolving, transformative, breathtaking, nestled, dynamic.

Avoid "Copula" Substitutions

Do not replace simple "is/are" verbs with flowery equivalents.

  • Bad: "The library serves as a center for learning."
  • Bad: "The statue stands as a monument to..."
  • Good: "The library is a center for learning."
  • Good: "The statue is a monument to..."

Eliminate "Elegant Variation"

Do not use synonyms just to avoid repeating a subject's name (e.g., "the eponymous character," "the titular protagonist," "the celebrated author"). It is acceptable to repeat the name or use pronouns naturally.

Banned Temporal Words in Code & Comments

Do not use relative temporal terms in code, variable names, function names, or comments. These words lose their meaning as the codebase evolves over time.

  • Banned Words: now, currently, existing behavior, previous behavior, old, new, modern.
  • Bad: // This function now uses the config parser instead of hardcoding.
  • Good: // Resolves paths via [ConfigParser.loadConfig] to support custom config locations.

2. Content & Tone

No "Puffery" or Forced Significance

Do not inflate the importance of a topic with vague praise. If a subject is important, the facts should demonstrate it without help.

  • Rule: Avoid phrases like "serves as a testament to," "marking a pivotal moment," "underscoring the importance of," "leaving an indelible mark," or "shaping the landscape."
  • Bad: "The founding of the institute marked a pivotal moment in the evolution of regional statistics, representing a significant shift toward independence."
  • Good: "The institute was founded in 1989 to collect regional statistics."

No Superficial Analysis

Avoid attaching "dangling" present-participle phrases that offer vague commentary.

  • Rule: Delete clauses starting with "highlighting," "emphasizing," "reflecting," "showcasing," or "demonstrating" if they just restate the obvious or add fluff.
  • Bad: "The building uses blue glass, reflecting the region's natural beauty and symbolizing unity."
  • Good: "The building uses blue glass."

Avoid Promotional Language

Maintain a neutral tone. Avoid "advertisement" words.

  • Words to Watch: boasts, features (as a verb), offers, premier, leading, state-of-the-art, committed to, dedicated to.
  • Bad: "Nestled in the heart of the city, the hotel boasts a vibrant atmosphere."
  • Good: "The hotel is located in the city center."

No "Challenges and Future Outlook" Formula

LLMs often end articles with a generic "Despite challenges... remains important" conclusion.

  • Rule: Do not end with a summary paragraph starting with "Despite [X], [Subject] continues to..." or speculating on the future. End with the last fact.
  • Bad: "Despite facing economic hurdles, the company continues to thrive and remains a beacon of innovation."

No "Title as Proper Noun" Leads

Do not treat a descriptive article title (like a list or broad topic) as a proper noun in the first sentence.

  • Bad: "The List of songs about Mexico is a curated compilation..."
  • Good: "This list contains songs about Mexico..."

Do not populate "See Also" sections with broad, generic terms.

  • Rule: Links must be directly relevant and specific to the subject.
  • Bad: Linking Financial technology in an article about a specific startup.
  • Good: Linking a competitor or specific related technology.

Attribution Precision

Do not use vague "weasel words."

  • Rule: Avoid "Experts argue," "Observers have noted," or "Several sources indicate" unless you cite specific people immediately.
  • Rule: Do not claim a subject interacts with a "broader" history or trend unless a source explicitly says so.

3. Sentence Structure

No Negative Parallelism

Avoid sentences that structure a contrast unnecessarily.

  • Bad: "It is not only a painting, but also a representation of..."
  • Bad: "It is not just about X; it is about Y."
  • Good: "It is a painting that represents..."

No "Rule of Three"

Avoid listing exactly three adjectives or three noun phrases to sound "comprehensive."

  • Bad: "The event brings together marketers, engineers, and designers." (Unless those specific three groups are the only ones).
  • Bad: "It is bold, innovative, and unique."

No False Ranges

Do not use "from X to Y" unless X and Y are endpoints of a logical scale (like time or size).

  • Bad: "The book covers everything from biology to space travel." (These are just two random topics, not a range).
  • Good: "The book covers topics including biology and space travel."

4. Structure & Formatting

Headers

  • Rule: Use Sentence case for headers (e.g., "Early life," not "Early Life").
  • Rule: Do not use "Title Case" in headers.

Formatting Avoidance

  • No Inline-Header Lists: Do not use the format: * **Header:** Description.... Use prose or simple lists.
  • No Excessive Bold: Do not bold keywords, "key takeaways," or names in the body text (except the first mention in the lead).
  • No Symbols/Emojis: Do not use emojis (🚀, 🧠) or unusual bullets (#, -) in lists. Use standard bullets (*).
  • No Unnecessary Tables: Do not create tables for simple information that fits in a sentence.
  • Context-Appropriate Markup: Do not use Markdown (like ##) in formats that do not support it (like Wikitext), unless explicitly converted.

Punctuation

  • Quotes: Use straight quotes (", ') and straight apostrophes ('). Do not use curly/smart quotes (, ).
  • Em Dashes: Use em dashes sparingly. LLMs overuse them for emphasis. Use commas or parentheses instead.

5. Citations & Integrity

No Hallucinations

  • Rule: Never generate a citation unless you are looking at the source.
  • Rule: Do not invent URLs or DOIs.
  • Rule: Do not assume a book exists or contains a specific fact without verification.

6. Communication (Chat Context)

  • No "Collaborative" Filler: Avoid starting responses with "Certainly!", "Here is the information," or "I hope this helps." Just provide the content.
  • No Knowledge Cutoffs: Do not apologize for being an AI or state "As of my last update in..." unless relevant to a specific time-sensitive fact.
  • No Subject Lines: Do not preface a response with Subject: ...
  • Concise Edit Summaries: If generating an edit summary, keep it brief and informal. Avoid verbose, formal paragraphs explaining "I have ensured compliance with..."
