# Summarize — Universal Content Extraction & Summarization

Five capabilities in one CLI tool: **Summarize**, **Scrape**, **Transcribe**, **Extract Slides**, **Batch Process**.

## Workflow Routing

| Request Pattern | Route To |
|---|---|
| Summarize URL/video/article, key takeaways from URL | `Workflows/SummarizeContent.md` |
| Extract transcript, YouTube transcript, transcribe audio/video | `Workflows/ExtractTranscript.md` |
| Scrape URL, extract webpage, get markdown from site | `Workflows/ScrapeWebpage.md` |
| Summarize multiple URLs, batch process | `Workflows/BatchProcess.md` |
| Extract slides, slides from video, OCR slides | `Workflows/SlideExtract.md` |

## Quick Decision Tree

```
User wants...
├── Summary of content → SummarizeContent
├── Raw text/transcript → ExtractTranscript
├── Webpage as Markdown → ScrapeWebpage
├── Multiple URLs processed → BatchProcess
└── Visual slides from video → SlideExtract
```

## Environment Setup

Source API keys before any summarize call:
```bash
[ -f ${AGENT_HOME}/.env ] && export $(grep -v '^#' ${AGENT_HOME}/.env | xargs)
export YT_DLP_PATH=$(which yt-dlp 2>/dev/null || echo ${HOME}/.local/bin/yt-dlp)
```

## Integration with ExtractWisdom

Summarize extracts and compresses. ExtractWisdom analyzes in depth.
Pipeline: `summarize --extract` → raw text → ExtractWisdom → structured insights.

## Scraping Tier Model

```
Tier 0: WebFetch (built-in, fastest, limited to static HTML)
Tier 1: Summarize --extract --format md (Readability + optional Firecrawl)
Tier 2: Scraping-Skill Bright Data Proxy (anti-bot bypass)
Tier 3: Scraping-Skill Playwright (full browser rendering)
Tier 4: Scraping-Skill Apify Actors (social media platforms)
```
Use Summarize for Tier 1 before escalating to heavier tools.
