Output

Markdown document with structure:

# [Extracted Title]

## Overview
[2-3 paragraph summary from analysis]

## Key Themes
- [Theme 1]
- [Theme 2]
...

## Detailed Analysis
[Detailed breakdown of content following its structure]

## Structure & Narrative Flow
[How the content progresses and why]

## Core Ideas
[Main concepts and their explanations]

## Important Quotes & Moments
> "Quote with context" (timestamp if applicable)

[More quotes with proper attribution]

## Context & Background
[What reader needs to understand the content]

## Related Concepts
[Connections to other topics]

Writing Guidelines

1. Overview: 2-3 sentences introducing the material
2. Key Themes: Bullet list of main topics (3-7 items)
3. Detailed Analysis: Follow the structure of the original content, breaking it into logical sections
4. Narrative Flow: Explain how ideas build on each other
5. Core Ideas: Define key concepts with examples from the material
6. Important Quotes: Extract 3-5 verbatim quotes with timestamps
7. Context: Explain what background knowledge helps understand this
8. Related: Link to other concepts mentioned or implied

Important Rules

✅ Preserve every important detail from source ✅ Include timestamps when available (format: HH:MM:SS) ✅ Use exact quotes (no paraphrasing) ✅ Document what's actually there, not what should be there ✅ Provide sufficient detail for future reference ✅ Use clear, professional markdown formatting ❌ Never add interpretation or analysis ❌ Never add opinions ❌ Never modify frontmatter when writing ❌ Never omit important information ❌ Never paraphrase direct quotes

Timestamp Format

For video/audio content, include timestamps:

• (0:30) - 30 seconds
• (2:45:30) - 2 hours 45 minutes 30 seconds
• Quote context: "The main issue is..." (12:34)

Citation Format

Reference materials where available:

• From same source: Just note the section or timestamp
• From other materials: [Topic](path/to/file.md) - Source Name

Quality Checklist

Before completing:

• ✅ All important points are included
• ✅ Quotes are exact and have context
• ✅ Timestamps are accurate
• ✅ Structure is logical and readable
• ✅ No interpretation added
• ✅ Enough detail for future use
• ✅ Formatting is clean and consistent

File Update Process

After generating markdown documentation, update the material file:

Step 1: Locate Material File

Search for the file matching the material ID:

*/items/ai.{material-id}.md

Common locations:

• youtube-channels/{channel-name}/items/ai.{id}.md
• podcasts/{podcast-name}/items/ai.{id}.md
• rss-feeds/{feed-name}/items/ai.{id}.md

Step 2: Write File Using Python Script

Use the Bash tool to invoke the update script:

python .claude/skills/content-documenter/scripts/update_material.py "path/to/items/ai.{id}.md" << 'EOF'
# Your markdown documentation here
## Section 1
Content...

## Section 2
More content...
EOF

The script will:

• ✅ Preserve the YAML frontmatter exactly
• ✅ Replace content below the frontmatter
• ✅ Update ai_status to "documented"
• ✅ Update generated_at timestamp
• ✅ Handle YAML parsing safely

Example

If documenting a video with ID v123 from Anthropic channel:

python .claude/skills/content-documenter/scripts/update_material.py "youtube-channels/Anthropic/items/ai.v123.md" << 'EOF'
# Understanding Constitutional AI

## Overview
This video discusses the Constitutional AI approach...

## Key Themes
- Safety in AI systems
- Alignment techniques
...
EOF

Important Notes

✅ Pass the complete markdown content (without frontmatter) to stdin ✅ The script handles file path validation and YAML parsing ✅ Always update the material file after generating documentation ✅ Check for success message in stderr output
