/digital-marketing-pro:content-brief
Purpose
Create a production-ready content brief that a writer can execute without additional context. Includes keyword strategy, content outline, structural requirements, brand voice guidelines, and on-page SEO specifications.
Input Required
The user must provide (or will be prompted for):
Topic or working title: What the content is about
Content type: Blog post, landing page, pillar page, guide, whitepaper, etc.
Target keyword(s): Primary keyword or topic cluster (or ask for research)
Target audience: Who this content is for
Funnel stage: Awareness, consideration, or decision
Competitive URLs: Optional — existing content to outperform
Process
Load brand context: Read ~/.claude-marketing/brands/_active-brand.json for the active slug, then load ~/.claude-marketing/brands/{slug}/profile.json. Apply brand voice, compliance rules for target markets (skills/context-engine/compliance-rules.md), and industry context. Also check for guidelines at ~/.claude-marketing/brands/{slug}/guidelines/_manifest.json — if present, load restrictions and relevant category files. Check for custom templates at ~/.claude-marketing/brands/{slug}/templates/. Check for agency SOPs at ~/.claude-marketing/sops/. If no brand exists, ask: "Set up a brand first (/digital-marketing-pro:brand-setup)?" — or proceed with defaults.
Research keyword landscape: primary keyword, secondary keywords, related questions
Analyze top-ranking content for the target keyword to identify gaps and opportunities
Define content angle and unique value proposition versus existing results
Build a detailed outline with H2/H3 structure, key points per section, and word count targets
Specify on-page SEO requirements: title tag, meta description, URL slug, internal links, schema markup
