Writing Clearly and Concisely

Overview

Write with clarity and force. This skill covers what to do (Strunk) and what not to do (AI patterns).

When to Use This Skill

Use this skill whenever you write prose for humans:

• Documentation, README files, technical explanations
• Commit messages, pull request descriptions
• Error messages, UI copy, help text, comments
• Reports, summaries, or any explanation
• Editing to improve clarity

If you're writing sentences for a human to read, use this skill.

Limited Context Strategy

When context is tight:

1. Write your draft using judgment
2. Dispatch a subagent with your draft and the relevant section file
3. Have the subagent copyedit and return the revision

Loading a single section (~1,000-4,500 tokens) instead of everything saves significant context.

Elements of Style

William Strunk Jr.'s _The Elements of Style_ (1918) teaches you to write clearly and cut ruthlessly.

Rules

Elementary Rules of Usage (Grammar/Punctuation):

1. Form possessive singular by adding 's
2. Use comma after each term in series except last
3. Enclose parenthetic expressions between commas
4. Comma before conjunction introducing co-ordinate clause
5. Don't join independent clauses by comma
6. Don't break sentences in two
7. Participial phrase at beginning refers to grammatical subject

Elementary Principles of Composition:

1. One paragraph per topic
2. Begin paragraph with topic sentence
3. Use active voice
4. Put statements in positive form
5. Use definite, specific, concrete language
6. Omit needless words
7. Avoid succession of loose sentences
8. Express co-ordinate ideas in similar form
9. Keep related words together
10. Keep to one tense in summaries
11. Place emphatic words at end of sentence

AI Writing Patterns to Avoid

LLMs regress to statistical means, producing generic, puffy prose. Avoid:

• Puffery: pivotal, crucial, vital, testament, enduring legacy
• Empty "-ing" phrases: ensuring reliability, showcasing features, highlighting capabilities
• Promotional adjectives: groundbreaking, seamless, robust, cutting-edge
• Overused AI vocabulary: delve, leverage, multifaceted, foster, realm, tapestry
• Formatting overuse: excessive bullets, emoji decorations, bold on every other word

Be specific, not grandiose. Say what it actually does.

For comprehensive research on why these patterns occur, see signs-of-ai-writing.md. Wikipedia editors developed this guide to detect AI-generated submissions — their patterns are well-documented and field-tested.

Bottom Line
