/content-writer — Marketing Content Writer

Write ready-to-use marketing content using proven copywriting frameworks from Schwartz, Ogilvy, Miller, Wiebe, Handley, and Cialdini.

When to Use

User says "write a post", "social media copy", "ad copy", "blog post", "email campaign"
Producing customer-facing marketing materials for any channel
Translating brand strategy and positioning into published content
Creating content variants for A/B testing

Before Starting

Check for existing context:

Read projects/<project>/brand-strategy.md — voice, personality, messaging pillars, and the "For Copywriter" handoff
Read projects/<project>/positioning.md — positioning statement, differentiators, narrative
Read projects/<project>/discovery.md — customer JTBD, struggling moments, desired outcomes
Read projects/<project>/gtm-plan.md — channel strategy and audience priorities

Brand strategy is critical input. If no brand strategy exists, flag it: "Writing without a defined voice is guesswork. Consider running /brand-strategist first — or tell me about the brand voice and I'll work with what we have."

If brand strategy exists, extract and apply throughout:

Voice do's and don'ts
Tone by context (the table maps tone to channel — use it)
Personality attributes ("X, but not Y")
Messaging pillars and proof points

Process

Step 1: Intake — What Are We Writing?

AskUserQuestion:
  question: "What type of content do you need?"
  header: "Content type"
  options:
    - label: "Social media posts"
      description: "LinkedIn, Twitter/X, Instagram, or other platform posts"
    - label: "Ad copy"
      description: "Google Ads, Meta Ads, display ads, or other paid media"
    - label: "Landing page / website copy"
      description: "Hero sections, feature blocks, CTAs, about pages"
    - label: "Email campaign / newsletter"
      description: "Drip sequences, announcements, newsletters, nurture emails"

Then gather specifics:

Platform/channel — Which specific platform or placement?
Audience — Who is this for? (Pull from discovery/positioning if available)
Goal — What should the reader do after reading? (click, sign up, share, buy, learn)
Key messages — What 1-3 things must this communicate?
Tone preferences — Anything beyond brand voice? (more casual, more urgent, etc.)
Constraints — Word/character count, required CTA, compliance requirements, hashtags, SEO keywords
Awareness level — How familiar is the audience with the product? (See Schwartz's 5 levels in references/copywriting-frameworks.md)

Step 2: Research — Parallel Intelligence

Launch 2 agents IN PARALLEL:

Agent 1 — Audience & Channel Research

Task(subagent_type: "general-purpose", description: "Research audience and channel")
prompt: Research what performs well for [CONTENT TYPE] on [PLATFORM] targeting [AUDIENCE].
  - What formats and structures get engagement on this platform right now?
  - What language and tone does this audience use to describe their problems?
  - What hooks, angles, or content styles are trending?
  - What are the platform-specific best practices and constraints?
  Return findings organized by: winning formats, audience language, and platform conventions.

Agent 2 — Competitive Content Analysis

Task(subagent_type: "general-purpose", description: "Research competitive content")
prompt: Research how competitors in [SPACE] create [CONTENT TYPE] on [PLATFORM].
  - What topics and angles do they cover?
  - What tone and positioning do they use?
  - What gaps exist in their content? (topics they miss, angles they avoid)
  - What gets the most engagement? What falls flat?
  Return competitive content intelligence with opportunities to differentiate.

Step 3: Write the Content

Select the right framework for the content type. See references/copywriting-frameworks.md for detailed frameworks.

Social Media Posts

Structure: Hook (stop the scroll) → Value (insight, story, or proof) → CTA (engage, click, share)
Frameworks: PAS for problem-focused posts, BAB for transformation stories
Produce 3-5 variants with different hooks and angles
Follow platform conventions from references (LinkedIn line breaks, Twitter thread structure, etc.)

Ad Copy

Match awareness level (Schwartz): Most Aware gets direct offers; Unaware gets story/identity hooks
Headlines: Ogilvy principles — benefit + specificity + news angle
Body: Cialdini persuasion triggers — social proof, authority, scarcity (used honestly)
Produce 3+ headline variants and 2+ body variants for A/B testing
Follow character limits per platform from references

Landing Page / Website Copy

Structure: Miller's StoryBrand — customer as hero, brand as guide
Hero section: Wiebe's hierarchy — headline (benefit) + subhead (mechanism) + CTA
Page flow: AIDA structure — attention → interest → desire → action
Include: Social proof bar, problem agitation, 3-step plan, proof section, final CTA
Write section by section with clear headers

Email Campaign / Newsletter

Subject lines: 6-10 words, specific, curiosity or benefit-driven. Write 3-5 options.
Preview text: Extends the subject line, doesn't repeat it
Body: Handley's rules — write for one person, "so what?" every sentence, show don't tell
Structure: One goal per email. One primary CTA. P.S. line for secondary hook.
For sequences: outline the arc across emails (opener → value → proof → urgency)

Blog Post / Article

Content tilt (Pulizzi): Find the angle no one else owns in this space
Structure: Hook → context → main argument (with subheads) → takeaway → CTA
SEO-aware: Include target keyword in title, H2s, and first 100 words naturally
Handley's rules: Utility x Inspiration x Empathy. Start with the end in mind.

Case Study

Structure: BAB framework — Before (the struggle) → After (the results) → Bridge (how you got there)
Expanded format: Situation → Challenge → Solution → Results → Customer Quote
Specifics over adjectives. "Reduced onboarding time from 3 weeks to 2 days" > "Dramatically improved onboarding"

Step 4: Review and Refine

Apply quality checks:

The Bar Test — Would the reader say this to a friend? If it sounds like marketing, rewrite.
The "So What?" Test — For every claim, ask "So what does this mean for the reader?" If you can't answer, cut it.
Brand Voice Check — Does this match the voice do's/don'ts and tone-by-context from brand strategy?
Specificity Check — Replace every vague claim with a specific proof point, metric, or example.
Awareness Match — Is this copy appropriate for how aware the audience is? (Don't pitch features to unaware readers.)

AskUserQuestion:
  question: "How does this feel? What needs adjustment?"
  header: "Review"
  options:
    - label: "Strong — minor tweaks"
      description: "The message and tone are right, just needs polish"
    - label: "Wrong tone"
      description: "The content is right but the voice or energy is off"
    - label: "Wrong angle"
      description: "The framing or hook isn't landing — try a different approach"

Iterate until the content feels authentic and ready to publish.

Step 5: Save

Save to: projects/<project>/content/<type>-<YYYY-MM-DD>.md (e.g., linkedin-posts-2025-01-15.md, google-ads-2025-01-15.md)

Include at the top of the file:

Content type and platform
Target audience
Key messages
Awareness level
Brand voice notes applied

Methodology
