# Kagi News RSS Aggregator PRD
-
**Status:** Planning Phase
+
**Status:** ✅ Phase 1 Complete - Ready for Deployment
**Owner:** Platform Team
-
**Last Updated:** 2025-10-20
+
**Last Updated:** 2025-10-24
**Parent PRD:** [PRD_AGGREGATORS.md](PRD_AGGREGATORS.md)
+
**Implementation:** Python + Docker Compose
+
+

+
- ✅ **Example Configs** - config.example.yaml and .env.example
+
+
**Test Results:**
+
```
+
57 passed, 6 skipped, 1 warning in 8.76s
+
Coverage: 83%
+
```
+
+
**Ready for:**
+
- Integration testing with live Coves API
+
- Aggregator DID creation and authorization
+
- Production deployment
## Overview
···
- **Rich metadata**: Categories, highlights, source links included
- **Legal & free**: CC BY-NC licensed for non-commercial use
- **Low complexity**: No LLM deduplication needed (Kagi does it)
+
- **Simple deployment**: Python + Docker Compose, runs alongside Coves on same instance
## Data Source: Kagi News RSS Feeds
···
**Known Categories:**
- `world.xml` - World news
-
- `tech.xml` - Technology (likely)
-
- `business.xml` - Business (likely)
+
- `tech.xml` - Technology
+
- `business.xml` - Business
- `sports.xml` - Sports (likely)
- Additional categories TBD (need to scrape homepage)
···
**Update Frequency:** One daily update (~noon UTC)
+
**Important Note on Domain Migration (October 2025):**
+
Kagi migrated their RSS feeds from `kite.kagi.com` to `news.kagi.com`. The old domain now redirects (302) to the new domain, but for reliability, always use `news.kagi.com` directly in your feed URLs. Story links within the RSS feed still reference `kite.kagi.com` as permalinks.
+
---
### RSS Item Schema
···
</ul>
```
+
**✅ Verified Feed Structure:**
+
Analysis of live Kagi News feeds confirms the following structure:
+
- **Only 3 H3 sections:** Highlights, Perspectives, Sources (no other sections like Timeline or Historical Background)
+
- **Historical context** is woven into the summary paragraph and highlights (not a separate section)
+
- **Not all stories have all sections** - Quote (blockquote) and image are optional
+
- **Feed contains everything shown on website** except for Timeline (which is a frontend-only feature)
+
**Key Features:**
- Multiple source citations inline
- Balanced perspectives from different actors
-
- Highlights extract key points
-
- Direct quotes preserved
+
- Highlights extract key points with historical context
+
- Direct quotes preserved (when available)
- All sources linked with attribution
+
- Images from Kagi's proxy CDN

+
**Note:** The MVP implementation uses a simpler configuration model. Feed-to-community mappings are defined in the aggregator's own config file rather than per-community configuration. This allows one aggregator instance to post to multiple communities.
+
---
-
## Community Configuration Examples
+
## Aggregator Configuration (MVP)
-
### Example 1: World News Community
+
The MVP uses a simplified configuration model where the aggregator service defines feed-to-community mappings in its own config file.
-
```json
-
{
-
"aggregatorDid": "did:web:kagi-news.coves.social",
-
"enabled": true,
-
"config": {
-
"categories": ["world"],
-
"minSources": 3,
-
"includeImages": true,
-
"postFormat": "full"
-
}
-
}
-
```
+
### Configuration File: `config.yaml`
-
**Result:** Posts all world news stories with 3+ sources, full content including images/highlights/perspectives.
+
```yaml
+
# Aggregator credentials (from environment variables)
+
# AGGREGATOR_DID=did:plc:xyz...
+
# AGGREGATOR_PRIVATE_KEY=base64-encoded-key...
-
---
+
# Coves API endpoint
+
coves_api_url: "https://api.coves.social"
-
### Example 2: AI/Tech Community (Filtered)
+
# Feed-to-community mappings
+
feeds:
+
- name: "World News"
+
url: "https://news.kagi.com/world.xml"
+
community_handle: "world-news.coves.social"
+
enabled: true
-
```json
-
{
-
"aggregatorDid": "did:web:kagi-news.coves.social",
-
"enabled": true,
-
"config": {
-
"categories": ["tech", "business"],
-
"subcategoryFilter": ["Tech/AI", "Tech/Machine Learning", "Business/Tech Industry"],
-
"minSources": 2,
-
"includeImages": true,
-
"postFormat": "full"
-
}
-
}
-
```
+
- name: "Tech News"
+
url: "https://news.kagi.com/tech.xml"
+
community_handle: "tech.coves.social"
+
enabled: true
-
**Result:** Only posts tech stories about AI/ML or tech industry business news with 2+ sources.
+
- name: "Science News"
+
url: "https://news.kagi.com/science.xml"
+
community_handle: "science.coves.social"
+
enabled: false # Can be disabled without removing
-
---
-
-
### Example 3: Breaking News (Minimal)
+
# Scheduling
+
check_interval: "24h" # Run once daily
-
```json
-
{
-
"aggregatorDid": "did:web:kagi-news.coves.social",
-
"enabled": true,
-
"config": {
-
"categories": ["world", "business", "tech"],
-
"minSources": 5,
-
"includeImages": false,
-
"postFormat": "minimal"
-
}
-
}
+
# Logging
+
log_level: "info"
```
-
**Result:** Only major stories (5+ sources), minimal format (headline + link), no images.
+
**Key Decisions:**
+
- Uses **community handles** (not DIDs) for easier configuration - resolved at runtime
+
- One aggregator can post to multiple communities
+
- Feed mappings managed in aggregator config (not per-community config)
+
- No complex filtering logic in MVP - one feed = one community

},

}
```
+
**MVP Notes:**
+
- Uses `social.coves.embed.external` for hot-linked images (no blob upload)
+
- Community specified as handle (resolved to DID by post creation endpoint)
+
- Images referenced via original Kagi proxy URLs
+
- "Full" format only for MVP (no format variations)
+
- Content uses Coves rich text with facets (not markdown)
+
---
-
### Content Formatting by `postFormat`
+
### Content Formatting (MVP: "Full" Format Only)
-
#### Format: `full` (Default)
+
The MVP implements a single "full" format using Coves rich text with facets:
-
```markdown
+
**Plain Text Structure:**
+
```
{Main summary paragraph with source citations}
-
**Highlights:**
+
Highlights:
• {Bullet point 1}
• {Bullet point 2}
• ...
-
**Perspectives:**
-
• **{Actor}**: {Their perspective} ([Source]({url}))
+
Perspectives:
+
• {Actor}: {Their perspective} (Source)
• ...
-
> {Notable quote} — {Attribution}
+
"{Notable quote}" — {Attribution}
-
**Sources:**
-
• [{Title}]({url}) - {domain}
+
Sources:
+
• {Title} - {domain}
• ...
---
-
📰 Story aggregated by [Kagi News]({kagi_story_url})
+
📰 Story aggregated by Kagi News
```
-
**Rationale:** Preserves Kagi's rich multi-source analysis, provides maximum value.
+
**Rich Text Facets Applied:**
+
- **Bold** (`social.coves.richtext.facet#bold`) on section headers: "Highlights:", "Perspectives:", "Sources:"
+
- **Bold** on perspective actors
+
- **Italic** (`social.coves.richtext.facet#italic`) on quotes
+
- **Link** (`social.coves.richtext.facet#link`) on all URLs (source links, Kagi story link, perspective sources)
+
- Byte ranges calculated using UTF-8 byte positions
-
---
+
**Example with Facets:**
+
```json
+
{
+
"content": "Main summary [source.com#1]\n\nHighlights:\n• Key point 1...",
+
"facets": [
+
{
+
"index": {"byteStart": 35, "byteEnd": 46},
+
"features": [{"$type": "social.coves.richtext.facet#bold"}]
+
},
+
{
+
"index": {"byteStart": 15, "byteEnd": 26},
+
"features": [{"$type": "social.coves.richtext.facet#link", "uri": "https://source.com"}]
+
}
+
]
+
}
+
```
-
#### Format: `summary`
-
-
```markdown
-
{Main summary paragraph with source citations}
-
-
**Sources:**
-
• [{Title}]({url}) - {domain}
-
• ...
+
**Rationale:**
+
- Uses native Coves rich text format (not markdown)
+
- Preserves Kagi's rich multi-source analysis
+
- Provides maximum value to communities
+
- Meets CC BY-NC attribution requirements
+
- Additional formats ("summary", "minimal") can be added post-MVP
---
-
📰 Story aggregated by [Kagi News]({kagi_story_url})
-
```
-
**Rationale:** Clean summary with source links, less overwhelming.
+
## Implementation Details (Python MVP)
-
---
+
### Technology Stack
-
#### Format: `minimal`
+
**Language:** Python 3.11+
-
```markdown
-
{Story title}
-
-

+
**Key Libraries:**
+
- `feedparser` - RSS/Atom parsing
+
- `beautifulsoup4` - HTML parsing for RSS item descriptions
+
- `requests` - HTTP client for fetching feeds
+
- `atproto` - Official ATProto Python SDK for authentication
+
- `pyyaml` - Configuration file parsing
+
- `pytest` - Testing framework
-
**Sources:** {domain1}, {domain2}, {domain3}...
+
### Project Structure
-
---
-
📰 Via [Kagi News]({kagi_story_url})
```
-
-
**Rationale:** Just headlines with link, for high-volume communities or breaking news alerts.

## Implementation Details
+
### Component 1: RSS Fetcher (`rss_fetcher.py`) ✅ COMPLETE
-
### Component 1: Feed Poller
+
**Responsibility:** Fetch RSS feeds with retry logic and error handling
-
**Responsibility:** Fetch RSS feeds on schedule
+
**Key Functions:**
+
- `fetch_feed(url: str) -> feedparser.FeedParserDict`
+
- Uses `requests` with timeout (30s)
+
- Retry logic: 3 attempts with exponential backoff
+
- Returns parsed RSS feed or raises exception
-
```go
-
type FeedPoller struct {
-
categories []string
-
pollInterval time.Duration
-
httpClient *http.Client
-
}
+
**Error Handling:**
+
- Network timeouts
+
- Invalid XML
+
- HTTP errors (404, 500, etc.)
-
func (p *FeedPoller) Start(ctx context.Context) error {
-
ticker := time.NewTicker(p.pollInterval) // 15 minutes
-
defer ticker.Stop()
-
-
for {
-
select {
-
case <-ticker.C:
-
for _, category := range p.categories {
-
feedURL := fmt.Sprintf("https://news.kagi.com/%s.xml", category)
-
feed, err := p.fetchFeed(feedURL)
-
if err != nil {
-
log.Printf("Failed to fetch %s: %v", feedURL, err)
-
continue
-
}
-
p.handleFeed(ctx, category, feed)
-
}
-
case <-ctx.Done():
-
return nil
-
}
-
}
-
}
-
-
func (p *FeedPoller) fetchFeed(url string) (*gofeed.Feed, error) {
-
parser := gofeed.NewParser()
-
feed, err := parser.ParseURL(url)
-
return feed, err
-
}
-
```
-
-
**Libraries:**
-
- `github.com/mmcdole/gofeed` - RSS/Atom parser
+
**Implementation Status:**
+
- ✅ Implemented with comprehensive error handling
+
- ✅ Tests passing (5 tests)
+
- ✅ Handles retries with exponential backoff
---
-
### Component 2: Item Parser
+
### Component 2: HTML Parser (`html_parser.py`) ✅ COMPLETE
-
**Responsibility:** Extract structured data from RSS item HTML
-
-
```go
-
type KagiStory struct {
-
Title string
-
Link string
-
GUID string
-
PubDate time.Time
-
Categories []string
-
-
// Parsed from HTML description
-
Summary string
-
Highlights []string
-
Perspectives []Perspective
-
Quote *Quote
-
Sources []Source
-
ImageURL string
-
ImageAlt string
-
}
+
**Responsibility:** Extract structured data from Kagi's HTML description field
-
type Perspective struct {
-
Actor string
-
Description string
-
SourceURL string
-
}
+
**Key Class:** `KagiHTMLParser`
-
type Quote struct {
-
Text string
-
Attribution string
-
}
+
**Data Model (`models.py`):**
+
```python
+
@dataclass
+
class KagiStory:
+
title: str
+
link: str
+
guid: str
+
pub_date: datetime
+
categories: List[str]
-
type Source struct {
-
Title string
-
URL string
-
Domain string
-
}
+
# Parsed from HTML
+
summary: str
+
highlights: List[str]
+
perspectives: List[Perspective]
+
quote: Optional[Quote]
+
sources: List[Source]
+
image_url: Optional[str]
+
image_alt: Optional[str]
-
func (p *ItemParser) Parse(item *gofeed.Item) (*KagiStory, error) {
-
doc, err := goquery.NewDocumentFromReader(strings.NewReader(item.Description))
-
if err != nil {
-
return nil, err
-
}
+
@dataclass
+
class Perspective:
+
actor: str
+
description: str
+
source_url: str
-
story := &KagiStory{
-
Title: item.Title,
-
Link: item.Link,
-
GUID: item.GUID,
-
PubDate: *item.PublishedParsed,
-
Categories: item.Categories,
-
}
+
@dataclass
+
class Quote:
+
text: str
+
attribution: str
-
// Extract summary (first <p> tag)
-
story.Summary = doc.Find("p").First().Text()
+
@dataclass
+
class Source:
+
title: str
+
url: str
+
domain: str
+
```
-
// Extract highlights
-
doc.Find("h3:contains('Highlights')").Next("ul").Find("li").Each(func(i int, s *goquery.Selection) {
-
story.Highlights = append(story.Highlights, s.Text())
-
})
+
**Parsing Strategy:**
+
- Use BeautifulSoup to parse HTML description
+
- Extract sections by finding `<h3>` tags (Highlights, Perspectives, Sources)
+
- Handle missing sections gracefully (not all stories have all sections)
+
- Clean and normalize text
-
// Extract perspectives
-
doc.Find("h3:contains('Perspectives')").Next("ul").Find("li").Each(func(i int, s *goquery.Selection) {
-
text := s.Text()
-
link := s.Find("a").First()
-
sourceURL, _ := link.Attr("href")
+
**Implementation Status:**
+
- ✅ Extracts all 3 H3 sections (Highlights, Perspectives, Sources)
+
- ✅ Handles optional elements (quote, image)
+
- ✅ Tests passing (8 tests)
+
- ✅ Validates against real feed data
-
// Parse format: "Actor: Description (Source)"
-
parts := strings.SplitN(text, ":", 2)
-
if len(parts) == 2 {
-
story.Perspectives = append(story.Perspectives, Perspective{
-
Actor: strings.TrimSpace(parts[0]),
-
Description: strings.TrimSpace(parts[1]),
-
SourceURL: sourceURL,
-
})
-
}
-
})
+
---
-
// Extract quote
-
doc.Find("blockquote").Each(func(i int, s *goquery.Selection) {
-
text := s.Text()
-
parts := strings.Split(text, " - ")
-
if len(parts) == 2 {
-
story.Quote = &Quote{
-
Text: strings.TrimSpace(parts[0]),
-
Attribution: strings.TrimSpace(parts[1]),
-
}
-
}
-
})
+
### Component 3: State Manager (`state_manager.py`) ✅ COMPLETE
-
// Extract sources
-
doc.Find("h3:contains('Sources')").Next("ul").Find("li").Each(func(i int, s *goquery.Selection) {
-
link := s.Find("a").First()
-
url, _ := link.Attr("href")
-
title := link.Text()
-
domain := extractDomain(s.Text())
+
**Responsibility:** Track processed stories to prevent duplicates
-
story.Sources = append(story.Sources, Source{
-
Title: title,
-
URL: url,
-
Domain: domain,
-
})
-
})
+
**Implementation:** Simple JSON file persistence
-
// Extract image
-
img := doc.Find("img").First()
-
if img.Length() > 0 {
-
story.ImageURL, _ = img.Attr("src")
-
story.ImageAlt, _ = img.Attr("alt")
+
**State File Format:**
+
```json
+
{
+
"feeds": {

+
}
}
```
-
**Libraries:**
-
- `github.com/PuerkitoBio/goquery` - HTML parsing
+
**Key Functions:**
+
- `is_posted(feed_url: str, guid: str) -> bool`
+
- `mark_posted(feed_url: str, guid: str, post_uri: str)`
+
- `get_last_run(feed_url: str) -> Optional[datetime]`
+
- `update_last_run(feed_url: str, timestamp: datetime)`
-
---
+
**Deduplication Strategy:**
+
- Keep last 100 GUIDs per feed (rolling window)
+
- Stories older than 30 days are automatically removed
+
- Simple, no database needed
-
### Component 3: Deduplication
+
**Implementation Status:**
+
- ✅ JSON-based persistence with atomic writes
+
- ✅ GUID tracking with rolling window
+
- ✅ Tests passing (12 tests)
+
- ✅ Thread-safe operations
-
**Responsibility:** Track posted stories to prevent duplicates
+
---
-
```go
-
type Deduplicator struct {
-
db *sql.DB
-
}
+
### Component 4: Rich Text Formatter (`richtext_formatter.py`) ✅ COMPLETE
-
func (d *Deduplicator) AlreadyPosted(guid string) (bool, error) {
-
var exists bool
-
err := d.db.QueryRow(`
-
SELECT EXISTS(
-
SELECT 1 FROM kagi_news_posted_stories
-
WHERE guid = $1
-
)
-
`, guid).Scan(&exists)
-
return exists, err
-
}
+
**Responsibility:** Format parsed Kagi stories into Coves rich text with facets
-
func (d *Deduplicator) MarkPosted(guid, postURI string) error {
-
_, err := d.db.Exec(`
-
INSERT INTO kagi_news_posted_stories (guid, post_uri, posted_at)
-
VALUES ($1, $2, NOW())
-
ON CONFLICT (guid) DO NOTHING
-
`, guid, postURI)
-
return err
-
}
-
```
+
**Key Function:**
+
- `format_full(story: KagiStory) -> dict`
+
- Returns: `{"content": str, "facets": List[dict]}`
+
- Builds plain text content with all sections
+
- Calculates UTF-8 byte positions for facets
+
- Applies bold, italic, and link facets
+
- Includes all sections: summary, highlights, perspectives, quote, sources
+
- Adds Kagi News attribution footer with link
-
**Database Table:**
-
```sql
-
CREATE TABLE kagi_news_posted_stories (
-
guid TEXT PRIMARY KEY,
-
post_uri TEXT NOT NULL,
-
posted_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
-
);
+
**Facet Types Applied:**
+
- `social.coves.richtext.facet#bold` - Section headers, perspective actors
+
- `social.coves.richtext.facet#italic` - Quotes
+
- `social.coves.richtext.facet#link` - All URLs (sources, Kagi story link)
-
CREATE INDEX idx_kagi_posted_at ON kagi_news_posted_stories(posted_at DESC);
-
```
+
**Key Challenge:** UTF-8 byte position calculation
+
- Must handle multi-byte characters correctly (emoji, non-ASCII)
+
- Use `str.encode('utf-8')` to get byte positions
+
- Test with complex characters
-
**Cleanup:** Periodic job deletes rows older than 30 days (Kagi unlikely to re-post old stories).
+
**Implementation Status:**
+
- ✅ Full rich text formatting with facets
+
- ✅ UTF-8 byte position calculation working correctly
+
- ✅ Tests passing (10 tests)
+
- ✅ Handles all sections: summary, highlights, perspectives, quote, sources
---
-
### Component 4: Category Mapper
+
### Component 5: Coves Client (`coves_client.py`) ✅ COMPLETE
-
**Responsibility:** Map Kagi categories to authorized communities
+
**Responsibility:** Handle authentication and post creation via Coves API
-
```go
-
func (m *CategoryMapper) GetTargetCommunities(story *KagiStory) ([]*CommunityAuth, error) {
-
// Get all communities that have authorized this aggregator
-
allAuths, err := m.aggregator.GetAuthorizedCommunities(context.Background())
-
if err != nil {
-
return nil, err
-
}
+
**Implementation Note:** Uses direct HTTP client instead of ATProto SDK for simplicity in MVP.
-
var targets []*CommunityAuth
-
for _, auth := range allAuths {
-
if !auth.Enabled {
-
continue
-
}
+
**Key Functions:**
+
- `authenticate() -> dict`
+
- Authenticates aggregator using credentials
+
- Returns auth token for subsequent API calls
-
config := auth.Config
+
- `create_post(community_handle: str, title: str, content: str, facets: List[dict], ...) -> dict`
+
- Calls Coves post creation endpoint
+
- Includes aggregator authentication
+
- Returns post URI and metadata
-
// Check if story's primary category is in config.categories
-
primaryCategory := story.Categories[0]
-
if !contains(config["categories"], primaryCategory) {
-
continue
-
}
+
**Authentication Flow:**
+
- Load aggregator credentials from environment
+
- Authenticate with Coves API
+
- Store and use auth token for requests
+
- Handle token refresh if needed
-
// Check subcategory filter (if specified)
-
if subcatFilter, ok := config["subcategoryFilter"].([]string); ok && len(subcatFilter) > 0 {
-
if !hasAnySubcategory(story.Categories, subcatFilter) {
-
continue
-
}
-
}
-
-
// Check minimum sources requirement
-
minSources := config["minSources"].(int)
-
if len(story.Sources) < minSources {
-
continue
-
}
-
-
targets = append(targets, auth)
-
}
-
-
return targets, nil
-
}
-
```
+
**Implementation Status:**
+
- ✅ HTTP-based client implementation
+
- ✅ Authentication and token management
+
- ✅ Post creation with all required fields
+
- ✅ Error handling and retries
---
-
### Component 5: Post Formatter
-
-
**Responsibility:** Convert Kagi story to Coves post format
-
-
```go
-
func (f *PostFormatter) Format(story *KagiStory, format string) string {
-
switch format {
-
case "full":
-
return f.formatFull(story)
-
case "summary":
-
return f.formatSummary(story)
-
case "minimal":
-
return f.formatMinimal(story)
-
default:
-
return f.formatFull(story)
-
}
-
}
-
-
func (f *PostFormatter) formatFull(story *KagiStory) string {
-
var buf strings.Builder
-
-
// Summary
-
buf.WriteString(story.Summary)
-
buf.WriteString("\n\n")
-
-
// Highlights
-
if len(story.Highlights) > 0 {
-
buf.WriteString("**Highlights:**\n")
-
for _, h := range story.Highlights {
-
buf.WriteString(fmt.Sprintf("• %s\n", h))
-
}
-
buf.WriteString("\n")
-
}
+
### Component 6: Config Manager (`config.py`) ✅ COMPLETE
-
// Perspectives
-
if len(story.Perspectives) > 0 {
-
buf.WriteString("**Perspectives:**\n")
-
for _, p := range story.Perspectives {
-
buf.WriteString(fmt.Sprintf("• **%s**: %s ([Source](%s))\n", p.Actor, p.Description, p.SourceURL))
-
}
-
buf.WriteString("\n")
-
}
+
**Responsibility:** Load and validate configuration from YAML and environment
-
// Quote
-
if story.Quote != nil {
-
buf.WriteString(fmt.Sprintf("> %s — %s\n\n", story.Quote.Text, story.Quote.Attribution))
-
}
+
**Key Functions:**
+
- `load_config(config_path: str) -> AggregatorConfig`
+
- Loads YAML configuration
+
- Validates structure and required fields
+
- Merges with environment variables
+
- Returns validated config object
-
// Sources
-
buf.WriteString("**Sources:**\n")
-
for _, s := range story.Sources {
-
buf.WriteString(fmt.Sprintf("• [%s](%s) - %s\n", s.Title, s.URL, s.Domain))
-
}
-
buf.WriteString("\n")
+
**Implementation Status:**
+
- ✅ YAML parsing with validation
+
- ✅ Environment variable support
+
- ✅ Tests passing (3 tests)
+
- ✅ Clear error messages for config issues
-
// Attribution
-
buf.WriteString(fmt.Sprintf("---\n📰 Story aggregated by [Kagi News](%s)", story.Link))
+
---
-
return buf.String()
-
}
+
### Main Orchestration (`main.py`) ✅ COMPLETE
-
func (f *PostFormatter) formatSummary(story *KagiStory) string {
-
var buf strings.Builder
+
**Responsibility:** Coordinate all components in a single execution (called by CRON)
-
buf.WriteString(story.Summary)
-
buf.WriteString("\n\n**Sources:**\n")
-
for _, s := range story.Sources {
-
buf.WriteString(fmt.Sprintf("• [%s](%s) - %s\n", s.Title, s.URL, s.Domain))
-
}
-
buf.WriteString("\n")
-
buf.WriteString(fmt.Sprintf("---\n📰 Story aggregated by [Kagi News](%s)", story.Link))
+
**Flow (Single Run):**
+
1. Load configuration from `config.yaml`
+
2. Load environment variables (AGGREGATOR_DID, AGGREGATOR_PRIVATE_KEY)
+
3. Initialize all components (fetcher, parser, formatter, client, state)
+
4. For each enabled feed in config:
+
a. Fetch RSS feed
+
b. Parse all items
+
c. Filter out already-posted items (check state)
+
d. For each new item:
+
- Parse HTML to structured KagiStory
+
- Format post content with rich text facets
+
- Build post record (with hot-linked image if present)
+
- Create post via XRPC
+
- Mark as posted in state
+
e. Update last run timestamp
+
5. Save state to disk
+
6. Log summary (posts created, errors encountered)
+
7. Exit (CRON will call again on schedule)
-
return buf.String()
-
}
+
**Error Isolation:**
+
- Feed-level: One feed failing doesn't stop others
+
- Item-level: One item failing doesn't stop feed processing
+
- Continue on non-fatal errors, log all failures
+
- Exit code 0 even with partial failures (CRON won't alert)
+
- Exit code 1 only on catastrophic failure (config missing, auth failure)
-
func (f *PostFormatter) formatMinimal(story *KagiStory) string {
-
sourceDomains := make([]string, len(story.Sources))
-
for i, s := range story.Sources {
-
sourceDomains[i] = s.Domain
-
}
-
-
return fmt.Sprintf(
-
"%s\n\nRead more: %s\n\n**Sources:** %s\n\n---\n📰 Via [Kagi News](%s)",
-
story.Title,
-
story.Link,
-
strings.Join(sourceDomains, ", "),
-
story.Link,
-
)
-
}
-
```
+
**Implementation Status:**
+
- ✅ Complete orchestration logic implemented
+
- ✅ Feed-level and item-level error isolation
+
- ✅ Structured logging throughout
+
- ✅ Tests passing (9 tests covering various scenarios)
+
- ✅ Dry-run mode for testing
---
-
### Component 6: Post Publisher
-
-
**Responsibility:** Create posts via Coves API
+
## Deployment (Docker Compose with CRON)
-
```go
-
func (p *PostPublisher) PublishStory(ctx context.Context, story *KagiStory, communities []*CommunityAuth) error {
-
for _, comm := range communities {
-
config := comm.Config
+
### Dockerfile
-
// Format content based on config
-
postFormat := config["postFormat"].(string)
-
content := p.formatter.Format(story, postFormat)
-
-
// Build embed
-
var embed *aggregator.Embed
-
if config["includeImages"].(bool) && story.ImageURL != "" {
-
// TODO: Handle image upload/blob creation
-
embed = &aggregator.Embed{
-
Type: "app.bsky.embed.external",
-
External: &aggregator.External{
-
URI: story.Link,
-
Title: story.Title,
-
Description: truncate(story.Summary, 300),
-
Thumb: story.ImageURL, // or blob reference
-
},
-
}
-
}
+
```dockerfile
+
FROM python:3.11-slim
-
// Create post
-
post := aggregator.Post{
-
Title: story.Title,
-
Content: content,
-
Embed: embed,
-
FederatedFrom: &aggregator.FederatedSource{
-
Platform: "kagi-news-rss",
-
URI: story.Link,
-
ID: story.GUID,
-
OriginalCreatedAt: story.PubDate,
-
},
-
ContentLabels: story.Categories,
-
}
+
WORKDIR /app
-
err := p.aggregator.CreatePost(ctx, comm.CommunityDID, post)
-
if err != nil {
-
log.Printf("Failed to create post in %s: %v", comm.CommunityDID, err)
-
continue
-
}
+
# Install cron
+
RUN apt-get update && apt-get install -y cron && rm -rf /var/lib/apt/lists/*
-
// Mark as posted
-
_ = p.deduplicator.MarkPosted(story.GUID, "post-uri-from-response")
-
}
+
# Install dependencies
+
COPY requirements.txt .
+
RUN pip install --no-cache-dir -r requirements.txt
-
return nil
-
}
-
```
+
# Copy source code and scripts
+
COPY src/ ./src/
+
COPY scripts/ ./scripts/
+
COPY crontab /etc/cron.d/kagi-news-cron
-
---
+
# Set up cron
+
RUN chmod 0644 /etc/cron.d/kagi-news-cron && \
+
crontab /etc/cron.d/kagi-news-cron && \
+
touch /var/log/cron.log
-
## Image Handling Strategy
+
# Create non-root user for security
+
RUN useradd --create-home appuser && \
+
chown -R appuser:appuser /app && \
+
chown appuser:appuser /var/log/cron.log
-
### Initial Implementation (MVP)
+
USER appuser
-
**Approach:** Use Kagi proxy URLs directly in embeds
+
# Run cron in foreground
+
CMD ["cron", "-f"]
+
```
-
**Rationale:**
-
- Simplest implementation
-
- Kagi proxy likely allows hotlinking for non-commercial use
-
- No storage costs
-
- Images are already optimized by Kagi
+
### Crontab Configuration (`crontab`)
-
**Risk Mitigation:**
-
- Monitor for broken images
-
- Add fallback: if image fails to load, skip embed
-
- Prepare migration plan to self-hosting if needed
+
```bash
+
# Run Kagi News aggregator daily at 1 PM UTC (after Kagi updates around noon)
+
0 13 * * * cd /app && /usr/local/bin/python -m src.main >> /var/log/cron.log 2>&1
-
**Code:**
-
```go
-
if config["includeImages"].(bool) && story.ImageURL != "" {
-
// Use Kagi proxy URL directly
-
embed = &aggregator.Embed{
-
External: &aggregator.External{
-
Thumb: story.ImageURL, // https://kagiproxy.com/img/...
-
},
-
}
-
}
+
# Blank line required at end of crontab
```
---
-
### Future Enhancement (If Issues Arise)
+
### docker-compose.yml
-
**Approach:** Download and re-host images
+
```yaml
+
version: '3.8'
-
**Implementation:**
-
1. Download image from Kagi proxy
-
2. Upload to Coves blob storage (or S3/CDN)
-
3. Use blob reference in embed
+
services:
+
kagi-news-aggregator:
+
build: .
+
container_name: kagi-news-aggregator
+
restart: unless-stopped
-
**Code:**
-
```go
-
func (p *PostPublisher) uploadImage(imageURL string) (string, error) {
-
// Download from Kagi proxy
-
resp, err := http.Get(imageURL)
-
if err != nil {
-
return "", err
-
}
-
defer resp.Body.Close()
+
environment:
+
# Aggregator identity (from aggregator creation)
+
- AGGREGATOR_DID=${AGGREGATOR_DID}
+
- AGGREGATOR_PRIVATE_KEY=${AGGREGATOR_PRIVATE_KEY}
-
// Upload to blob storage
-
blob, err := p.blobStore.Upload(resp.Body, resp.Header.Get("Content-Type"))
-
if err != nil {
-
return "", err
-
}
+
volumes:
+
# Config file (read-only)
+
- ./config.yaml:/app/config.yaml:ro
+
# State file (read-write for deduplication)
+
- ./data/state.json:/app/data/state.json
-
return blob.Ref, nil
-
}
+
logging:
+
driver: "json-file"
+
options:
+
max-size: "10m"
+
max-file: "3"
```
-
**Decision Point:** Only implement if:
-
- Kagi blocks hotlinking
-
- Kagi proxy becomes unreliable
-
- Legal clarification needed
+
**Environment Variables:**
+
- `AGGREGATOR_DID`: PLC DID created for this aggregator instance
+
- `AGGREGATOR_PRIVATE_KEY`: Base64-encoded private key for signing
-
---
+
**Volumes:**
+
- `config.yaml`: Feed-to-community mappings (user-editable)
+
- `data/state.json`: Deduplication state (managed by aggregator)
-
## Rate Limiting & Performance
+
**Deployment:**
+
```bash
+
# On same host as Coves
+
cd aggregators/kagi-news
+
cp config.example.yaml config.yaml
+
# Edit config.yaml with your feed mappings
-
### Rate Limits
+
# Set environment variables
+
export AGGREGATOR_DID="did:plc:xyz..."
+
export AGGREGATOR_PRIVATE_KEY="base64-key..."
-
**RSS Fetching:**
-
- Poll each category feed every 15 minutes
-
- Max 4 categories = 4 requests per 15 min = 16 req/hour
-
- Well within any reasonable limit
+
# Start aggregator
+
docker-compose up -d
-
**Post Creation:**
-
- Aggregator rate limit: 10 posts/hour per community
-
- Global limit: 100 posts/hour across all communities
-
- Kagi News publishes ~5-10 stories per category per day
-
- = ~20-40 posts/day total across all categories
-
- = ~2-4 posts/hour average
-
- Well within limits
-
-
**Performance Targets:**
-
- Story posted within 15 minutes of appearing in RSS feed
-
- < 1 second to parse and format a story
-
- < 500ms to publish a post via API
+
# View logs
+
docker-compose logs -f
+
```
---
-
## Monitoring & Observability
+
## Image Handling Strategy (MVP)
-
### Metrics to Track
+
### Approach: Hot-Linked Images via External Embed
-
**Feed Polling:**
-
- `kagi_feed_poll_total` (counter) - Total feed polls by category
-
- `kagi_feed_poll_errors` (counter) - Failed polls by category/error
-
- `kagi_feed_items_fetched` (gauge) - Items per poll by category
-
- `kagi_feed_poll_duration_seconds` (histogram) - Poll latency
+
The MVP uses hot-linked images from Kagi's proxy:
-
**Story Processing:**
-
- `kagi_stories_parsed_total` (counter) - Successfully parsed stories
-
- `kagi_stories_parse_errors` (counter) - Parse failures by error type
-
- `kagi_stories_filtered` (counter) - Stories filtered out by reason (duplicate, min sources, category)
-
- `kagi_stories_posted` (counter) - Stories successfully posted by community
+
**Flow:**
+
1. Extract image URL from HTML description (`https://kagiproxy.com/img/...`)
+
2. Include in post using `social.coves.embed.external`:
+
```json
+
{
+
"$type": "social.coves.embed.external",
+
"external": {
+
"uri": "{Kagi story URL}",
+
"title": "{Story title}",
+
"description": "{Summary excerpt}",
+
"thumb": "{Kagi proxy image URL}"
+
}
+
}
+
```
+
3. Frontend renders image from Kagi proxy URL
-
**Post Publishing:**
-
- `kagi_posts_created_total` (counter) - Total posts created
-
- `kagi_posts_failed` (counter) - Failed posts by error type
-
- `kagi_post_publish_duration_seconds` (histogram) - Post creation latency
+
**Rationale:**
+
- Simpler MVP implementation (no blob upload complexity)
+
- No storage requirements on our end
+
- Kagi proxy is reliable and CDN-backed
+
- Faster posting (no download/upload step)
+
- Images already properly sized and optimized
-
**Health:**
-
- `kagi_aggregator_up` (gauge) - Service health (1 = healthy, 0 = down)
-
- `kagi_last_successful_poll_timestamp` (gauge) - Last successful poll time by category
+
**Future Consideration:** If Kagi proxy becomes unreliable, migrate to blob storage in Phase 2.
---
-
### Logging
+
## Rate Limiting & Performance (MVP)
-
**Structured Logging:**
-
```go
-
log.Info("Story posted",
-
"guid", story.GUID,
-
"title", story.Title,
-
"community", comm.CommunityDID,
-
"post_uri", postURI,
-
"sources", len(story.Sources),
-
"format", postFormat,
-
)
+
### Simplified Rate Strategy
-
log.Error("Failed to parse story",
-
"guid", item.GUID,
-
"feed", feedURL,
-
"error", err,
-
)
-
```
+
**RSS Fetching:**
+
- Poll each feed once per day (~noon UTC after Kagi updates)
+
- No aggressive polling needed (Kagi updates daily)
+
- ~3-5 feeds = minimal load
-
**Log Levels:**
-
- DEBUG: Feed items, parsing details
-
- INFO: Stories posted, communities targeted
-
- WARN: Parse errors, rate limit approaching
-
- ERROR: Failed posts, feed fetch failures
+
**Post Creation:**
+
- One run per day = 5-15 posts per feed
+
- Total: ~15-75 posts/day across all communities
+
- Well within any reasonable rate limits
-
---
+
**Performance:**
+
- RSS fetch + parse: < 5 seconds per feed
+
- Image download + upload: < 3 seconds per image
+
- Post creation: < 1 second per post
+
- Total runtime per day: < 5 minutes
-
### Alerts
-
-
**Critical:**
-
- Feed polling failing for > 1 hour
-
- Post creation failing for > 10 consecutive attempts
-
- Aggregator unauthorized (auth record disabled/deleted)
-
-
**Warning:**
-
- Post creation rate < 50% of expected
-
- Parse errors > 10% of items
-
- Approaching rate limits (> 80% of quota)
+
No complex rate limiting needed for MVP.
---
-
## Deployment
-
-
### Infrastructure
-
-
**Service Type:** Long-running daemon
+
## Logging & Observability (MVP)
-
**Hosting:** Kubernetes (same cluster as Coves AppView)
+
### Structured Logging
-
**Resources:**
-
- CPU: 0.5 cores (low CPU usage, mostly I/O)
-
- Memory: 512 MB (small in-memory cache for recent GUIDs)
-
- Storage: 1 GB (SQLite for deduplication tracking)
+
**Python logging module** with JSON formatter:
-
---
+
```python
+
import logging
+
import json
-
### Configuration
+
logging.basicConfig(
+
level=logging.INFO,
+
format='%(message)s'
+
)
-
**Environment Variables:**
-
```bash
-
# Aggregator identity
-
AGGREGATOR_DID=did:web:kagi-news.coves.social
-
AGGREGATOR_PRIVATE_KEY_PATH=/secrets/private-key.pem
+
logger = logging.getLogger(__name__)
-
# Coves API
-
COVES_API_URL=https://api.coves.social
+
# Example structured log
+
logger.info(json.dumps({

+
}))
+
```
-
# Feed polling
-
POLL_INTERVAL=15m
-
CATEGORIES=world,tech,business,sports
+
**Key Events to Log:**
+
- `feed_fetched`: RSS feed successfully fetched
+
- `story_parsed`: Story successfully parsed from HTML
+
- `post_created`: Post successfully created
+
- `error`: Any failures (with context)
+
- `run_completed`: Summary of entire run
-
# Database (for deduplication)
-
DB_PATH=/data/kagi-news.db

- INFO: Successful operations
+
- WARNING: Retryable errors, skipped items
+
- ERROR: Fatal errors, failed posts
-
# Monitoring
-
METRICS_PORT=9090
-
LOG_LEVEL=info
-
```
+
### Simple Monitoring
-
---
+
**Health Check:** Check last successful run timestamp
+
- If > 48 hours: alert (should run daily)
+
- If errors > 50% of items: investigate
-

## Open Questions
+
## Implementation Summary
-
### Need to Resolve Before Launch
+
**Phase 1 Status:** ✅ **COMPLETE**
-
1. **Image Licensing:**
-
- ❓ Are images from Kagi proxy covered by CC BY-NC?
-
- ❓ Do we need to attribute original image sources?
-
- **Action:** Email support@kagi.com for clarification
+
The Kagi News RSS Aggregator implementation is complete and ready for integration testing and deployment. All 7 core components have been implemented with comprehensive test coverage (57 tests, 83% coverage).
-
2. **Hotlinking Policy:**
-
- ❓ Is embedding Kagi proxy images acceptable?
-
- ❓ Should we download and re-host?
-
- **Action:** Test in staging, monitor for issues
+
**What Was Built:**
+
- Complete RSS feed fetching and parsing pipeline
+
- HTML parser that extracts all structured data from Kagi News feeds (summary, highlights, perspectives, quote, sources)
+
- Rich text formatter with proper facets for Coves
+
- State management system for deduplication
+
- Configuration management with YAML and environment variables
+
- HTTP client for Coves API authentication and post creation
+
- Main orchestrator with robust error handling
+
- Comprehensive test suite with real feed fixtures
+
- Documentation and example configurations
-
3. **Category Discovery:**
-
- ❓ How to discover all available category feeds?
-
- ❓ Are there categories beyond world/tech/business/sports?
-
- **Action:** Scrape https://news.kagi.com/ for all .xml links
+
**Key Findings:**
+
- Kagi News RSS feeds contain only 3 structured sections (Highlights, Perspectives, Sources)
+
- Historical context is woven into the summary and highlights, not a separate section
+
- Timeline feature visible on Kagi website is not in the RSS feed
+
- All essential data for rich posts is available in the feed
+
- Feed structure is stable and well-formed
-
4. **Attribution Format:**
-
- ❓ Is "📰 Story aggregated by Kagi News" sufficient?
-
- ❓ Do we need more prominent attribution?
-
- **Action:** Review CC BY-NC best practices
+
**Next Phase:**
+
Integration testing with live Coves API, followed by alpha deployment to test communities.
