# RSS Agent Viewer

CLI RSS/Atom feed viewer with built-in discovery, caching, and search.

## Quick start

```bash
npx -y rss-agent-viewer init
npx -y rss-agent-viewer discover https://vercel.com
npx -y rss-agent-viewer add https://vercel.com/atom
npx -y rss-agent-viewer read
```

## Core workflow

```bash
# Initialize config + database
rss-viewer init

# Discover feeds for a site
rss-viewer discover https://example.com

# Subscribe to a feed (optional: --timeout for slow feeds)
rss-viewer add https://example.com/feed.xml
rss-viewer add https://slow-site.com/feed.xml --timeout 30000

# List feeds and read articles
rss-viewer feeds
rss-viewer read
```

## Common commands

```bash
rss-viewer init
rss-viewer add <url>
rss-viewer discover <url>
rss-viewer feeds
rss-viewer remove <url>
rss-viewer read [url]
rss-viewer search <query>
rss-viewer discover-search <query>
rss-viewer import <file>
rss-viewer export
rss-viewer cache <action>
rss-viewer cleanup
```

## Usage patterns

### Discover and subscribe
```bash
rss-viewer discover https://example.com
rss-viewer add https://example.com/rss.xml
```

### Read a single feed
```bash
rss-viewer read https://example.com/rss.xml
```

### Read all feeds (fetches fresh by default)
```bash
# Fetches fresh articles from all feeds in parallel
rss-viewer read

# Use cached data only (skip network requests)
rss-viewer read --cached

# Limit results
rss-viewer read --limit 10

# One latest article per feed (feed-diverse results)
rss-viewer read --latest-per-feed --limit 10

# Timeouts (for slow feeds or many feeds)
rss-viewer read --timeout 15000 --overall-timeout 180000
```

### Clean up invalid feeds
```bash
# Remove broken and duplicate feeds
rss-viewer cleanup

# Preview what would be removed
rss-viewer cleanup --dry-run

# Only remove broken feeds
rss-viewer cleanup --broken

# Only remove duplicates
rss-viewer cleanup --duplicates
```

### Search across all feeds
```bash
# Local database search (enhanced with full-text search)
rss-viewer search "open source"

# Web search + discovery + add + search in one command
rss-viewer discover-search "Rust programming" --auto-add --read

# Using Exa API (BYOK)
rss-viewer discover-search "AI safety" \
  --provider exa \
  --max-results 5 \
  --auto-add \
  --read
```

### Import OPML
```bash
rss-viewer import feeds.opml
```

### Export feeds
```bash
rss-viewer export
```

## Search Options

### Local Database Search
```bash
rss-viewer search "React 19" --limit 10
rss-viewer search "TypeScript" --author "Dan" --since "2024-01-01"
```

### Web Search with Discovery
```bash
# Use agent's built-in search (default)
rss-viewer discover-search "micro-frontends" --auto-add --read

# Use Exa API (requires EXA_API_KEY)
export EXA_API_KEY="your-api-key"
rss-viewer discover-search "WebGPU" \
  --provider exa \
  --max-results 5 \
  --category Development \
  --auto-add \
  --read \
  --limit 20
```

### Configuration
