Content Style

The Iron Laws

1. NO EM DASHES. EVER.

Not "—", not "–", not "--". Use periods, commas, or split into separate sentences.

2. GRADE-8 READABILITY OR FAIL.

Short sentences, simple words, clear structure. No academic jargon. No corporate bloat.

3. WORD COUNT BANDS ARE MANDATORY.

  • Blog posts: 1000-1500 words
  • Case studies: 500-800 words
  • Internal docs: 600-1200 words

With

--strict
flag: ±10% tolerance only.

Purpose

Ensure all marketing content maintains:

  • Accessible, skimmable writing (grade-8 readability)
  • Clean punctuation (no em dashes)
  • Appropriate length for content type
  • Bold key phrases for scanability
  • Logical section structure with clear subheadings

When to Use This Skill

Activate automatically when:

  • Drafting blog posts, case studies, or documentation
  • Verifying content before publication
  • User explicitly requests style checking
  • Content workflows invoke this quality gate
  • --strict
    flag is set (enforces tighter word count tolerance)

Style Requirements

1. Readability: Grade-8 Target

Characteristics of grade-8 readability:

  • Average sentence length: 15-20 words
  • Simple, common vocabulary
  • Active voice preferred over passive
  • One idea per sentence
  • Short paragraphs (2-4 sentences)

Pass examples:

✓ "Seasonal demand fluctuates. Plan your campaigns accordingly."
✓ "Customers prefer personalized emails. Use segmentation to deliver relevant content."
✓ "Most users churn before their first send. Reduce onboarding friction to improve retention."

Fail examples:

✗ "The implementation of sophisticated segmentation methodologies facilitates enhanced personalization paradigms." (Grade 16+, corporate jargon)
✗ "Leveraging cutting-edge AI-driven predictive analytics enables stakeholders to optimize engagement metrics." (Grade 18+, buzzword soup)

Validation method:

  • Use readability formulas (Flesch-Kincaid, Gunning Fog)
  • Target: Grade 7-9 (acceptable range)
  • Flag: Grade 10+ (requires simplification)

2. Punctuation: Zero Em Dashes

Forbidden characters:

  • (em dash)
  • (en dash used as em dash)
  • --
    (double hyphen as em dash substitute)

Acceptable alternatives:

✗ "Email campaigns—when executed correctly—drive significant revenue."
✓ "Email campaigns drive significant revenue when executed correctly."

✗ "Three factors matter: personalization, timing—and relevance."
✓ "Three factors matter: personalization, timing, and relevance."

✗ "Users want simplicity—but most platforms overcomplicate setup."
✓ "Users want simplicity. Most platforms overcomplicate setup."
✓ "Users want simplicity, but most platforms overcomplicate setup."

Validation method:

  • Scan entire draft for
    ,
    ,
    --
  • Report exact line/location of violations
  • Block completion until all removed

3. Word Count Bands

Default bands:

Content TypeMinimumMaximumStrict (±10%)
Blog post10001500900-1650
Case study500800450-880
Internal docs6001200540-1320

Validation method:

  1. Count words in draft (exclude YAML frontmatter, footnotes)
  2. Determine content type from intent.yaml or metadata
  3. Apply appropriate band
  4. If
    --strict
    flag: enforce ±10% tolerance
  5. If outside band: FAIL with specific overage/underage

Reporting:

Blog post: 1847 words (target 1000-1500)
✗ FAIL: 347 words over maximum
Required action: Cut 347+ words or split into multiple pieces

4. Skimmable Structure

Required elements:

  • Clear H1 (title)
  • Descriptive H2s (section headings)
  • Optional H3s (subsection headings)
  • Bold key phrases (2-5 per section)
  • Short paragraphs (2-4 sentences)
  • Bulleted or numbered lists where appropriate

Pass example:

# How to Plan Seasonal Email Campaigns

## Identify High-Demand Periods

Most ecommerce brands see **predictable demand spikes** during holidays and seasonal events. Analyze your historical data to find patterns.

Key periods to consider:
- Black Friday / Cyber Monday
- Valentine's Day (for gifting brands)
- Back-to-school (August-September)

## Align Campaign Timing

Launch campaigns **2-3 weeks before peak demand**. This gives customers time to browse, compare, and purchase.

Fail example:

# Seasonal Email Strategy

The implementation of seasonal email campaign strategies requires comprehensive analysis of historical demand patterns, customer behavior analytics, and competitive landscape assessment. Organizations should leverage data-driven insights to optimize timing, messaging, and segmentation approaches across multiple touchpoints and channels to maximize engagement and conversion outcomes.

5. Soft Raleon Integration

Guideline: Single-line Raleon mention (≈1x per piece)

Pass examples:

✓ "Raleon automates this segmentation based on real-time behavior data."
✓ "Tools like Raleon learn these patterns and adjust send times automatically."

Fail examples:

✗ "Raleon is the best, most advanced, industry-leading platform for email marketing that outperforms all competitors and delivers unmatched results." (Over-selling, superlatives)
✗ [Multiple Raleon mentions throughout] (Too promotional)

Validation Process

1. Load Draft

Read draft from:

  • datasets/marketing/content/{date}_{type}_{slug}/drafts/draft_v{n}.md
  • In-memory draft content

2. Apply Style Checks

Run all checks in parallel:

Em Dash Scan:

grep -n '—\|–\|--' draft.md

Report line numbers and context.

Word Count:

# Exclude YAML frontmatter and footnotes
wc -w draft.md

Compare to band for content type.

Readability:

  • Calculate Flesch-Kincaid Grade Level
  • Calculate Gunning Fog Index
  • Average the two scores
  • Compare to target (7-9)

Structure Check:

  • Verify H1 exists (exactly one)
  • Count H2s (minimum 3 for blogs, 2 for case studies)
  • Verify bold usage (at least 1 per major section)
  • Check paragraph length (flag paragraphs >6 sentences)

3. Generate Report

If all pass:

# Content Style Validation: PASS

✓ No em dashes detected
✓ Word count: 1247 (target 1000-1500)
✓ Readability: Grade 8.2 (Flesch-Kincaid 8.1, Gunning Fog 8.3)
✓ Structure: Clear H1, 5 H2s, appropriate bold usage
✓ Raleon integration: 1 mention (appropriate)

**Status**: Ready for publication

If any fail:

# Content Style Validation: FAIL

✗ Em dashes detected:
  - Line 42: "Email campaigns—when executed correctly—drive revenue"
  - Line 87: "Three factors matter: personalization, timing—and relevance"

✗ Word count: 1847 (target 1000-1500)
  - 347 words over maximum
  - Requires cutting or splitting

✗ Readability: Grade 11.4 (target 7-9)
  - Average sentence length: 28 words (target 15-20)
  - Requires simplification

**Required fixes**:
1. Remove/replace 2 em dashes
2. Cut 350+ words
3. Simplify sentences (reduce avg length to <20 words)

**Status**: NEEDS_FIX

4. Block or Approve

If PASS:

  • Draft can proceed to snippets or publication
  • Style validation complete

If FAIL:

  • Draft blocked from next step
  • Workflow status set to "NEEDS_FIX"
  • Must address violations before resuming

Integration with Workflows

Content Pipeline Integration

Invoked by:

  • content-drafting
    workflow (before marking draft complete)
  • content-verification
    workflow (explicit style check)

Blocking behavior:

  • If style check fails → draft cannot proceed
  • Workflow paused until fixes applied
  • User must address violations

Strict Mode (
--strict
flag)

When enabled:

  • Word count tolerance reduced to ±10%
  • Readability target narrowed to Grade 7.5-8.5
  • Paragraph length maximum reduced to 4 sentences
  • All violations become blocking (no warnings)

Success Criteria

Style validation passes when:

  • Zero em dashes in draft
  • Word count within band (or strict tolerance)
  • Readability grade 7-9
  • Clear H1/H2 structure
  • Appropriate bold usage for skimmability
  • Single soft Raleon mention

Common Mistakes

MistakeFix
Em dashes presentReplace with periods, commas, or split sentences
Word count overCut content or split into multiple pieces
Readability too high (Grade 12+)Simplify sentences, use common words
Missing H2 structureAdd section headings every 200-300 words
Long paragraphs (>6 sentences)Break into shorter paragraphs
Over-selling RaleonSingle soft mention, no superlatives

Anti-Rationalization Blocks

Common excuses that are explicitly rejected:

RationalizationReality
"One em dash won't hurt"Zero tolerance. Remove it.
"This topic requires complex language"Grade-8 or fail. Simplify.
"It's only 50 words over"Bands exist for a reason. Cut it.
"Readers will understand long sentences"Keep sentences <20 words average.
"We can fix style in editing"Fix now or block workflow.
