# youtube-summarizer

## Purpose

This skill extracts transcripts from YouTube videos and generates comprehensive, verbose summaries using the STAR + R-I-S-E framework. It validates video availability, extracts transcripts using the `youtube-transcript-api` Python library, and produces detailed documentation capturing all insights, arguments, and key points.

The skill is designed for users who need thorough content analysis and reference documentation from educational videos, lectures, tutorials, or informational content.

## When to Use This Skill

This skill should be used when:

- User provides a YouTube video URL and wants a detailed summary
- User needs to document video content for reference without rewatching
- User wants to extract insights, key points, and arguments from educational content
- User needs transcripts from YouTube videos for analysis
- User asks to "summarize", "resume", or "extract content" from YouTube videos
- User wants comprehensive documentation prioritizing completeness over brevity

## Main Workflow

### Progress Tracking Guidelines

Throughout the workflow, display a visual progress gauge before each step to keep the user informed. The gauge format is:

```bash
echo "[████░░░░░░░░░░░░░░░░] 20% - Step 1/5: Validating URL"
```

**Format specifications:**
- 20 characters wide (use █ for filled, ░ for empty)
- Percentage increments: Step 1=20%, Step 2=40%, Step 3=60%, Step 4=80%, Step 5=100%
- Step counter showing current/total (e.g., "Step 3/5")
- Brief description of current phase

**Display the initial status box before Step 1:**

```

║ ○ Step 3: Extracting Transcript                              ║
║ ○ Step 4: Generating Summary                                 ║
║ ○ Step 5: Formatting Output                                  ║
╠══════════════════════════════════════════════════════════════╣
║ Progress: ██████░░░░░░░░░░░░░░░░░░░░░░░░  20%               ║
╚══════════════════════════════════════════════════════════════╝
```

### Step 5: Format and Present Output

**Progress:**
```bash
echo "[████████████████████] 100% - Step 5/5: Formatting Output"
```

**Objective:** Deliver the summary in clean, well-structured Markdown.

**Output Structure:**

```markdown
