Writing Clearly and Concisely

Overview

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

WARNING: elements-of-style.md consumes ~12,000 tokens. Read it only when writing or editing prose.

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 elements-of-style.md
3. Have the subagent copyedit and return the revision

If you REALLY REALLY need to preserve context, you can skip the full elements-of-style.md and instead use Orwell's rules:

• Never use a metaphor, simile, or other figure of speech which you are used to seeing in print.
• Never use a long word where a short one will do.
• If it is possible to cut a word out, always cut it out.
• Never use the passive where you can use the active.
• Never use a foreign phrase, a scientific word, or a jargon word if you can think of an everyday English equivalent.
• Break any of these rules sooner than say anything outright barbarous.
