RSS News Dataset & Deduplicator

Aggregate public RSS, Atom, and RDF feeds into one normalized article dataset. The Actor collapses the same canonical article across feeds, strips common tracking parameters, filters by keyword or publication window, and stores a snapshot for NEW versus SEEN scheduled-run workflows.

What it returns

Each article row includes the normalized article URL, title, publication date, author, categories, summary text, bounded content text, source feeds, duplicate count, matched keywords, and incremental status.

Feed failures stay visible in SUMMARY.feedErrors while successful feeds continue. REPORT provides a compact Markdown run summary and article preview.

Inputs

• feedUrls: up to 20 public RSS, Atom, or RDF URLs
• maxItemsPerFeed: parsed-entry cap per feed
• maxItems: final dataset cap after filtering and deduplication
• maxRetainedBytes: run-level normalized-data memory budget
• includeKeywords / excludeKeywords: case-insensitive article filters
• publishedAfterDays: optional publication window; dated filtering excludes entries without a parseable date
• stripTracking: remove common tracking query parameters before deduplication
• snapshotKey and saveSnapshot: incremental NEW / SEEN state

Guardrails

• Public HTTP(S) feeds only; private, loopback, reserved, and local network addresses are rejected.
• DNS results are pinned for each request so a hostname cannot be re-resolved to a private address after validation.
• Feed URL length, redirects, request time, feed bytes, feed count, concurrency, retained normalized data, and output rows are capped.
• XML parsing runs in an isolated worker with time and heap limits; item normalization is capped before article objects are built.
• Failed feeds retain their prior per-feed snapshot state. A run where every feed fails exits as failed without replacing the snapshot.
• XML entity processing is disabled; output text is cleaned after parsing.
• No browser, proxy, API key, or external AI service is required.

Local validation

npm test
npm run smoke

The first Store release should remain free while organic usage is measured. A future PPE boundary is article-emitted, charged only for visible normalized article rows, never failed feeds or entries removed before output.
