Context Engine — Shared Marketing Intelligence

When to Use This Skill

• User is setting up a new brand or project for marketing
• User switches between brands/clients (agency use case)
• Any other marketing skill needs brand context, industry data, compliance rules, or platform specs
• User asks about industry benchmarks, platform requirements, or regulatory compliance

Required Context

This skill loads and manages:

1. Brand Profile — identity, voice, audiences, competitors, goals (from ~/.claude-marketing/brands/)
2. Industry Profiles — benchmarks, KPIs, channel effectiveness per industry (see industry-profiles.md)
3. Compliance Rules — geographic privacy laws + industry regulations (see compliance-rules.md)
4. Platform Specs — character limits, image sizes, algorithm signals per platform (see platform-specs.md)
5. Scoring Rubrics — standardized evaluation criteria for all content types (see scoring-rubrics.md)

Brand Profile Management

Loading a Brand

1. Check ~/.claude-marketing/brands/_active-brand.json for the currently active brand
2. If active brand exists, load ~/.claude-marketing/brands/{slug}/profile.json
3. If no active brand, prompt: "No active brand configured. Run /digital-marketing-pro:brand-setup to create one, or tell me about your brand and I'll help set it up."

Switching Brands

When user says "switch to [brand name]":

1. Run: python "scripts/setup.py" --switch-brand SLUG
2. The script handles fuzzy matching, validation, and updates _active-brand.json
3. Confirm: "Switched to [brand_name]. All marketing outputs will now use this brand's voice, compliance rules, and context."

Or use: /digital-marketing-pro:switch-brand

How Other Modules Use This Skill

Every module should:

1. Check if an active brand exists before producing marketing outputs
2. Load relevant industry profile for benchmarks and channel recommendations
3. Auto-apply compliance rules based on brand's target_markets and industry.regulation_codes
4. Reference platform specs when creating platform-specific content
5. Use scoring rubrics when evaluating or grading content quality
6. Use adaptive scoring — run adaptive-scorer.py to get brand-specific weights before content scoring
7. Save campaign data — use campaign-tracker.py to persist plans, performance, and insights
8. Check past campaigns — before making recommendations, check if similar campaigns exist in brand history

Business Model Types

The following types trigger different funnel models, KPI frameworks, and channel strategies:

• B2B_SaaS — MRR/ARR focused, product-led or sales-led growth
• B2C_eCommerce — ROAS focused, product catalog marketing
• B2C_DTC — Direct-to-consumer brand building + performance
• B2B_Services — Thought leadership, long sales cycles
• Local_Business — Google Business Profile, local SEO, reviews
• Agency — Multi-client management, white-label outputs
• Creator — Personal brand, audience building, monetization
• Enterprise — ABM, buying committees, complex sales
• Non_Profit — Donor acquisition, awareness, advocacy
• Marketplace — Two-sided acquisition, liquidity, trust

Brand Voice Scoring

The brand voice scorer (brand-voice-scorer.py) automatically normalizes profile data:

• Reads brand_voice.formality (1-10 int scale) → converts to 0.0-1.0 float internally
• Maps brand_voice.prefer_words → preferred_words, brand_voice.avoid_words → avoided_words
• Supports both the full profile schema (from brand-setup) and legacy direct schemas

Data Persistence

Campaign data, performance snapshots, and marketing insights persist across sessions:

~/.claude-marketing/brands/{slug}/
├── campaigns/              # Campaign plans and post-mortems
│   ├── _index.json         # Campaign index for quick lookup
│   └── {id}.json           # Individual campaign data
├── performance/            # Performance snapshots over time
│   └── {campaign}-{date}.json
├── insights.json           # Marketing learnings (last 200)
├── content-library/        # Saved content pieces
└── voice-samples/          # Brand voice reference content

Use campaign-tracker.py for all persistence operations.

MCP Integrations

When MCP servers are configured (in .mcp.json), modules can pull real data:

• Google Analytics → actual traffic/conversion data for performance reports
• Google Search Console → real ranking data for SEO audits
• Google Ads / Meta → live campaign performance for paid advertising
• HubSpot → CRM data for funnel analysis
• Mailchimp → email campaign metrics
• Google Sheets → export reports and calendars

All MCP servers connect to the USER'S OWN accounts via their API keys.
