name: content-engine description: "Draft marketing content in brand voice — blog posts, ad copy, email sequences, social posts, landing pages, and brand-voice guides — through a gated pipeline (research, outline, draft, fact-check, humanize, voice check, SEO checklist) with numbered working files and a five-gate quality scorecard before copy is publish-ready. Triggers on "/digital-marketing-pro:content-engine", "write a blog post about X", "draft ad copy for this campaign", "create an email sequence", "landing page copy for our product". Takes /digital-marketing-pro:content-brief as preferred upstream; hands off to /digital-marketing-pro:publish-blog, /digital-marketing-pro:content-repurpose, and /digital-marketing-pro:check. Reads the brand profile, guidelines, platform specs, and compliance rules." argument-hint: "[content-type and topic]"

Brand Context (Auto-Applied)

Before producing any marketing output from this module:

1. Check session context — The active brand summary was output at session start. Use the brand name, industry, voice settings, channels, goals, compliance, and competitors shown there.
2. If you need the full profile, read: ~/.claude-marketing/brands/{slug}/profile.json
3. Apply brand voice — Formality, energy, humor, authority levels must shape all content tone and word choices
4. Check compliance — Auto-apply rules for brand's target_markets and industry using skills/context-engine/compliance-rules.md
5. Reference industry benchmarks — Consult skills/context-engine/industry-profiles.md for the brand's industry
6. Use platform specs — Reference skills/context-engine/platform-specs.md for character limits and format requirements
7. Check campaign history — Run python "${CLAUDE_PLUGIN_ROOT}/scripts/campaign-tracker.py" --brand {slug} --action list-campaigns before planning new work
8. If no brand exists, say: "No brand profile found. Use /digital-marketing-pro:brand-setup to create one, or I can proceed with general best practices."
9. Check brand guidelines — If ~/.claude-marketing/brands/{slug}/guidelines/_manifest.json exists, load and enforce: restrictions.md for banned words, restricted claims, and mandatory disclaimers; channel-styles.md for channel-specific tone overrides (may differ from base voice); messaging.md for approved key messages, taglines, and positioning language; voice-and-tone.md for detailed voice rules beyond the 4 numeric scores. If producing content for a specific channel, channel style rules take precedence over base voice settings.

Do not ask the user for information that already exists in their brand profile.

Required Context

Before executing content work, gather:

1. Content Type: Which specific content format is needed?
2. Audience: Who is this content for? (Link to personas from Audience Intelligence if available)
3. Objective: What should this content achieve? (Traffic, conversions, engagement, education, retention)
4. Brand Voice: Does a brand voice guide exist? What is the tone? (Professional, casual, authoritative, playful, etc.)
5. Keywords/Topics: For SEO content — target keywords, search intent, and competitive landscape
6. Platform: Where will this content live? (Platform-specific requirements matter)
7. Funnel Stage: Where does this content fit in the customer journey?
8. Existing Content: What related content already exists? (Avoid cannibalization)
9. Constraints: Word count limits, character limits, regulatory disclaimers, brand guidelines
10. Performance Benchmarks: What does success look like for this content type?

For quick requests (e.g., "write me a LinkedIn post"), infer reasonable defaults and deliver immediately. For strategic content work, gather full context.

Process

Primary Workflow: Content Creation

1. Content Strategy Alignment

   • Confirm the content type, audience, objective, and funnel stage
   • Check for existing content that may overlap (prevent cannibalization)
   • Identify the core message and key takeaway
   • Select the appropriate content framework for the task

2. Research & Preparation

   • For SEO content: Analyze target keyword, search intent, SERP features, and top-ranking content
   • For ad copy: Review platform specs, competitor ads, and audience pain points
   • For email: Identify the sequence trigger, desired action, and subscriber segment
   • For social: Check platform trends, optimal formats, and audience behavior patterns
   • For landing pages: Identify the traffic source, visitor intent, and conversion goal

3. Content Creation

   • Apply the brand voice guidelines (or establish them if none exist)
   • Write to the specific format requirements (character limits, structure, platform norms)
   • Build in persuasion architecture:
     • Attention: Hook/headline that stops the scroll or earns the click
     • Interest: Problem-aware framing that demonstrates understanding
     • Desire: Solution positioning with clear benefits and social proof
     • Action: Clear, specific CTA with reduced friction
   • Include SEO elements where applicable (keywords, headers, internal links, meta data)
   • Write multiple variations for testing when the format supports it (ad copy, subject lines, CTAs)

4. Quality Assurance

   • Brand voice alignment check
   • Readability score assessment (aim for grade 8 or below for general audiences). Run the analyzer on the draft:

     python "${CLAUDE_PLUGIN_ROOT}/scripts/readability-analyzer.py" \
         --file "${CLAUDE_PLUGIN_DATA}/{brand}/seo/content-engine/{date}/{slug}/03-draft-v1.md" \
         --target b2c_general
     

     (--text inline or --file path — mutually exclusive, one required; --target one of b2c_general, b2b_professional, b2b_technical, children, academic.)
   • Accessibility review (heading hierarchy, alt text guidance, link text clarity)
   • Fact-checking for any claims, statistics, or references
   • Platform compliance check (ad policies, character limits, format requirements)
   • SEO on-page audit (keyword placement, meta data, internal links) for search content
   • AI content quality check if AI-assisted (originality, brand alignment, factual accuracy)

5. Optimization & Testing Plan

   • Define what to A/B test (headlines, CTAs, email subject lines, ad creative)
   • Set performance benchmarks based on content type and channel
   • Schedule content review dates for decay monitoring
   • Plan content repurposing across formats and channels

Secondary Workflow: Content Audit & Refresh

1. Pull content inventory (URLs, publish dates, current traffic/rankings)
2. Score each piece on freshness, performance trend, and relevance
3. Categorize: Keep (performing well), Refresh (declining but fixable), Consolidate (thin/overlapping), Remove (irrelevant/harmful)
4. Prioritize refresh candidates by traffic recovery potential
5. Create refresh briefs with specific update instructions
