What every-style-editor does

The skill edits copy in four stages. It reviews the document context, scans each sentence, audits mechanical consistency, and compiles an itemized issue report. Every flagged problem includes the paragraph number, original excerpt, corrected phrasing, and the corresponding rule reference.

Checks target headline casing, active voice, and number formatting, spelling out one through nine while using numerals for 10 and above. Punctuation rules enforce Oxford commas and closed em dashes. For text styling, bold emphasis is prohibited in favor of italics alone. Links must span two to four words and avoid generic phrases like "click here".

Full evaluation relies on EVERY_WRITE_STYLE.md. Without that file, the agent operates only on the baseline rules embedded directly in the skill.

What it helps with

  • audit draft copy against Every editorial standards
  • identify grammatical errors and punctuation slipups line by line
  • replace passive constructions and filler words
  • standardize headline capitalization and link anchor text

Example prompts for the agent

  • Review draft.md against the Every style guide and output the findings report.
  • Check this newsletter draft for passive voice and overused words.
  • Audit the headline capitalization and list formatting in article.md.

# Every Style Editor

This skill provides a systematic approach to reviewing copy against Every's comprehensive style guide. It transforms Claude into a meticulous line editor and proofreader specializing in grammar, mechanics, and style guide compliance.

## When to Use This Skill

Use this skill when:
- Reviewing articles, blog posts, newsletters, or any written content
- Ensuring copy follows Every's specific style conventions
- Providing feedback on grammar, punctuation, and mechanics
- Flagging deviations from the Every style guide
- Preparing clean copy for human editorial review

## Skill Overview

This skill enables performing a comprehensive review of written content in four phases:

1. **Initial Assessment** - Understanding context and document type
2. **Detailed Line Edit** - Checking every sentence for compliance
3. **Mechanical Review** - Verifying formatting and consistency
4. **Recommendations** - Providing actionable improvement suggestions

## How to Use This Skill

### Step 1: Initial Assessment

Begin by reading the entire piece to understand:
- Document type (article, knowledge base entry, social post, etc.)
- Target audience
- Overall tone and voice
- Content context

### Step 2: Detailed Line Edit

Review each paragraph systematically, checking for:
- Sentence structure and grammar correctness
- Punctuation usage (commas, semicolons, em dashes, etc.)
- Capitalization rules (especially job titles, headlines)
- Word choice and usage (overused words, passive voice)
- Adherence to Every style guide rules

Reference the complete [EVERY_WRITE_STYLE.md](./references/EVERY_WRITE_STYLE.md) for specific rules when in doubt.

### Step 3: Mechanical Review

Verify:
- Spacing and formatting consistency
- Style choices applied uniformly throughout
- Special elements (lists, quotes, citations)
- Proper use of italics and formatting
- Number formatting (numerals vs. spelled out)
- Link formatting and descriptions

### Step 4: Output Results

Present findings using this structure:

```

## Style Guide Reference

The complete Every style guide is included in [EVERY_WRITE_STYLE.md](./references/EVERY_WRITE_STYLE.md). Key areas to focus on:

- **Quick Rules**: Title case for headlines, sentence case elsewhere
- **Tone**: Active voice, avoid overused words (actually, very, just), be specific
- **Numbers**: Spell out one through nine; use numerals for 10+
- **Punctuation**: Oxford commas, em dashes without spaces, proper quotation mark usage
- **Capitalization**: Lowercase job titles, company as singular (it), teams as plural (they)
- **Emphasis**: Italics only (no bold for emphasis)
- **Links**: 2-4 words, don't say "click here"

## Key Principles

- **Be specific**: Always quote the exact text with the error
- **Reference rules**: Cite the specific style guide rule for each correction
- **Maintain voice**: Preserve the author's voice while correcting errors
- **Prioritize clarity**: Focus on changes that improve readability
- **Be constructive**: Frame feedback to help writers improve
- **Flag ambiguous cases**: When style guide doesn't address an issue, explain options and recommend the clearest choice

## Common Areas to Focus On

Based on Every's style guide, pay special attention to:

- Punctuation (comma usage, semicolons, apostrophes, quotation marks)
- Capitalization (proper nouns, titles, sentence starts)
- Numbers (when to spell out vs. use numerals)
- Passive voice (replace with active whenever possible)
- Overused words (actually, very, just)
- Lists (parallel structure, punctuation, capitalization)
- Hyphenation (compound adjectives, except adverbs)
- Word usage (fewer vs. less, they vs. them)
- Company references (singular "it", teams as plural "they")
- Job title capitalization
