Expand

Skill: Expand Content (Micro → Pillar)

Trigger

"Expand this into a newsletter" / "Turn this into an article" / "Make this a newsletter" / User provides a LinkedIn post to expand.

Process

Step 1: Load references

• Always load: references/newsletter-practices.md, references/format-adaptation-matrix.md
• Load expert: experts/brunson-storytelling.md (Epiphany Bridge for narrative expansion)
• Load expert: experts/ogilvy-headlines.md (subject line generation)
• Load for critique: references/rubber-duck-escalator.md

Step 2: Analyze source post

Read the LinkedIn post and identify compressed elements:

1. Core claim — What's the main argument?
2. Implied evidence — What stats, studies, or examples are referenced or hinted at but not fully developed?
3. Hinted stories — What personal experiences or case studies are compressed into 1-2 sentences?
4. Mentioned frameworks — What models or structures are named but not fully explained?
5. Missing counterarguments — What "but what about..." questions would a sharp reader ask?
6. Angle — Which angle is the source post? (This informs expansion strategy.)

Step 3: Mini-research from Brain

Load relevant Brain sections to find deeper evidence:

• evidence_bank — Find 2-3 additional stats that support the core claim
• topic_depth_layers — Pull key debates, common mistakes, practitioner wisdom on the topic
• newsletter_insights — Find cross-references from 2+ newsletter sources
• synthesized_mental_models — Identify relevant mental model to weave in

Step 4: Expand using newsletter structure

Follow the full structure from references/newsletter-practices.md:

1. Opening story (200-400 words)

   • If source post hints at a story → expand using Epiphany Bridge (7-step)
   • If source is framework-based → create a scene that reveals why the framework matters
   • If source is contrarian → open with the moment you realized the common view was wrong

2. Bridge to insight (100-200 words)

   • Connect the story to the core claim naturally

3. Deep framework/evidence section (600-1200 words)

   • Fully develop the framework or argument that was compressed in the LinkedIn post
   • Add the 2-3 evidence anchors from mini-research
   • Cross-reference 2+ newsletter sources
   • Include the "only I could have written this" section (200+ words)
   • Use rejection-based teaching where appropriate

4. Practitioner callout (200-400 words)

   • "What most get wrong" — the compressed insights from the LinkedIn post become the foundation
   • Expand with specific examples and counterarguments

5. Landing (100-200 words)

   • Connect back to opening story
   • Specific, actionable takeaway

6. P.S.

   • Secondary CTA or personal note

Step 5: Generate subject line + preview text

Using Ogilvy headline principles:

1. Write 5 subject line variations
2. Select the best (curiosity + specificity)
3. Write preview text that extends (not repeats) the subject line

Step 6: Critique (Rubber Duck Escalator)

Run all 5 phases with newsletter-adapted scoring:

1. MIRROR demands 2-3 specific experiential moments (vs 1 for LinkedIn)
2. CHALLENGE demands 3+ evidence anchors
3. CRYSTALLIZE checks 1500-3000 word range and subject line quality
4. All phases must score 8+
5. Max 3 iterations

Step 7: Present to user

Show the full newsletter with scorecard and subject line options.
