What it does

Natural Writing is an agent skill from flutter/flutter. 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.

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering Humanizing AI text and Cross-platform mobile apps. It works with Flutter and Dart. The repository describes itself as: Flutter makes it easy and fast to build beautiful apps for mobile and beyond. The licence is BSD-3-Clause.

When your agent uses it

  • Authoring longer text
  • Like analysis documents
  • CL descriptions

Example prompts

  • “Use the natural-writing skill to contain well-defined rules for creating natural, accurate, and readable writing”
  • “/natural-writing”

What it can do on your machine

Read from SKILL.md and the folder at commit fe75cab. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Natural Writing loads about 1.9k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 1,028 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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..."
