Corey Haines c29ee7e6db Optimize skill files for AI agent use with progressive disclosure
- Fix marketplace.json: add 2 missing skills (content-strategy, product-marketing-context)
- Refactor 10 skills over 500 lines to use references/ folders:
  - email-sequence: 926 → 291 lines
  - social-content: 809 → 276 lines
  - competitor-alternatives: 750 → 253 lines
  - pricing-strategy: 712 → 226 lines
  - programmatic-seo: 628 → 235 lines
  - referral-program: 604 → 239 lines
  - schema-markup: 598 → 175 lines
  - free-tool-strategy: 576 → 176 lines
  - paywall-upgrade-cro: 572 → 224 lines
  - marketing-ideas: 566 → 165 lines

Each skill now has core workflow in SKILL.md (<500 lines) with detailed
content in references/ folder for progressive disclosure.

Email Copy Guidelines

Structure

  1. Hook: First line grabs attention
  2. Context: Why this matters to them
  3. Value: The useful content
  4. CTA: What to do next
  5. Sign-off: Human, warm close

Formatting

  • Short paragraphs (1-3 sentences)
  • White space between sections
  • Bullet points for scanability
  • Bold for emphasis (sparingly)
  • Mobile-first (most read on phone)

Tone

  • Conversational, not formal
  • First-person (I/we) and second-person (you)
  • Active voice
  • Match your brand but lean friendly
  • Read it out loud—does it sound human?

Length

  • Shorter is usually better
  • 50-125 words for transactional
  • 150-300 words for educational
  • 300-500 words for story-driven
  • If it's long, it better be good
  • Buttons: Primary actions, high-visibility
  • Links: Secondary actions, in-text
  • One clear primary CTA per email
  • Button text: Action + outcome

Personalization

Merge Fields

  • First name (fallback to "there" or "friend")
  • Company name (B2B)
  • Relevant data (usage, plan, etc.)

Dynamic Content

  • Based on segment
  • Based on behavior
  • Based on stage

Triggered Emails

  • Action-based sends
  • More relevant than time-based
  • Examples: Feature used, milestone hit, inactivity

Segmentation Strategies

By Behavior

  • Openers vs. non-openers
  • Clickers vs. non-clickers
  • Active vs. inactive

By Stage

  • Trial vs. paid
  • New vs. long-term
  • Engaged vs. at-risk

By Profile

  • Industry/role (B2B)
  • Use case / goal
  • Company size

Testing and Optimization

What to Test

  • Subject lines (highest impact)
  • Send times
  • Email length
  • CTA placement and copy
  • Personalization level
  • Sequence timing

How to Test

  • A/B test one variable at a time
  • Sufficient sample size
  • Statistical significance
  • Document learnings

Metrics to Track

  • Open rate (benchmark: 20-40%)
  • Click rate (benchmark: 2-5%)
  • Unsubscribe rate (keep under 0.5%)
  • Conversion rate (specific to sequence goal)
  • Revenue per email (if applicable)
