# /cm:compound — Document Learnings

Capture and compound marketing knowledge after completing work.

## What It Does

Systematically documents what you learned so future marketing work benefits from this project's insights.

## Process

1. **Identify What Was Learned**
   - Ask: What worked?
   - Ask: What didn't work?
   - Ask: What surprised you?
   - Ask: What would you do differently?

2. **Categorize Learning**
   - Positioning insight
   - Copywriting pattern
   - CRO finding
   - Channel effectiveness
   - Customer insight
   - Competitive intel

3. **Document in Learnings File**
   - Check if `.agents/learnings/[category].md` exists
   - If not, create it
   - Append new learning with:
     - Date
     - Context (what project)
     - Finding
     - Evidence
     - Implication (what to do next time)

4. **Update Relevant Skills** (if pattern emerges)
   - If this learning should inform future skill execution, note it
   - Example: "Audiences respond better to outcome-focused headlines than feature-focused"
   - Add to references or skill notes

5. **Confirm Compounding**
   - Acknowledge what was captured
   - Suggest how to apply it to next project

## When to Use

- After completing a major project (launch, campaign, page)
- After running an A/B test (whether it won or lost)
- After customer research (capture insights)
- Quarterly review (synthesize patterns)

## Time Investment

10-15 minutes

## Output

- Updated learnings file (`.agents/learnings/[category].md`)
- Optional skill updates (if pattern is strong)
- Confirmation of what was captured

## Philosophy

Marketing knowledge compounds when you capture what you learn. Every project should make the next project easier. This command is how you ensure that happens.
