### Step 3: Validate Quality

- [ ] Free of jargon unless essential

## Examples

**What the skill does:**
1. Processes transcript
2. Identifies decisions made
3. Notes action items
4. Summarizes discussions

**Result:** Structured summary with decisions, action items, and next steps

## Quality Standards

Summaries should be:
- **Accurate** - No misrepresentation of source material
- **Concise** - Typically 20-30% of original length
- **Objective** - Neutral tone without injecting opinions
- **Complete** - All critical information preserved
- **Clear** - Easily understood by someone who hasn't read the original

## Troubleshooting

### Problem: Summary too long

**Solution:**
- Focus on main points only
- Remove redundant information
- Eliminate examples unless crucial
- Target 20-30% of original length

### Problem: Missing important context

**Solution:**
- Re-read with focus on "why" not just "what"
- Include essential background information
- Note key relationships between concepts

### Problem: Too much detail

**Solution:**
- Ask: "Would someone need this to understand the core message?"
- Keep statistics only if they're central to the argument
- Save deep details for "Details" section if requested

## Best Practices

1. **Read once completely before summarizing** - Get the full picture first
2. **Use the author's language for key terms** - Maintain accuracy
3. **Preserve the logical flow** - Don't just list facts randomly
4. **Note the intended audience** - Adjust complexity accordingly
5. **Include source context** - Date, author, publication when relevant

## Limitations

This skill works best for:
- Text-based content (articles, documents, reports)
- Lengths from 500 to 10,000 words
- Non-technical to moderately technical content

May require adjustment for:
- Highly specialized technical papers
- Content requiring domain expertise to evaluate
- Multi-media content with essential visual elements
