Workflow

Step 1: Fetch RSS feeds

Run the bundled fetcher script:

node <skill_dir>/scripts/fetch-rss.mjs --hours <HOURS> --sources <skill_dir>/references/sources.json

This outputs JSON to stdout. Capture it. The script:

• Fetches 92 RSS/Atom feeds concurrently (15 parallel, 15s timeout)
• Parses XML (RSS 2.0 + Atom)
• Filters articles by time window
• Outputs sorted JSON array of {title, link, summary, date, source, sourceUrl}

Step 2: Score and classify

From the fetched articles JSON, score each article on three dimensions (1-10):

1. Relevance — How relevant to AI, software engineering, security, or tech industry
2. Quality — Depth of insight, originality, technical substance
3. Timeliness — Breaking news or emerging trend vs. evergreen content

Classify into categories:

• 🤖 AI / ML
• 🔒 Security
• ⚙️ Engineering
• 🛠 Tools / Open Source
• 💡 Opinion / Essay
• 📝 Other

Select the top N articles by total score.

Step 3: Generate summaries

For each selected article:

1. If summary from RSS is sufficient (>100 chars), use it as basis
2. If not, use web_fetch to read the full article
3. Generate a structured summary:
   • Chinese title translation (keep original as link text)
   • 2-3 sentence summary covering: core problem → key insight → conclusion
   • Recommendation reason (1 sentence)
   • Keywords (2-3 tags)

Step 4: Generate trend highlights

Analyze all selected articles together and identify 2-3 macro trends in the tech world today.

Step 5: Format output

Output as a Telegram-friendly message (not a file):

Notes

• No external API key needed. The agent itself handles scoring and summarization.
• RSS sources are from Karpathy's curated list of Hacker News top blogs.
• If exec is unavailable, fall back to using web_fetch on individual RSS URLs (slower but works).
• The script requires Node.js 18+ (available on all OpenClaw instances).
• Source list can be customized by editing references/sources.json.
