DEPRECATED: This skill has been replaced by memory/check_seen and memory/mark_seen tools. Use fetch-rss-feeds or other collection skills which handle deduplication automatically through the Memory MCP server.

Deduplicate Articles (DEPRECATED)

⚠️ DEPRECATED: This skill has been deprecated as of v2.0.0.

Deduplication is now handled automatically by collection skills using the Memory MCP server's check_seen and mark_seen tools.

Migration Guide

Before (v1.0)

Collection and deduplication were separate skills:

fetch-rss-feeds - Collect articles
deduplicate-articles - Remove duplicates

After (v2.0)

Deduplication is built into collection skills:

fetch-rss-feeds - Collects AND deduplicates using memory/check_seen

How to Migrate

If you were using deduplicate-articles, update your workflow to use the v2.0 collection skills which handle deduplication automatically.

The new approach:

Before storing an article, call memory/check_seen with the article URL as key
If not seen, store the article with memory/add
Mark as seen with memory/mark_seen

This is now handled automatically by all collection skills.

Replacement Tools

Old Approach	New Approach
`deduplicate-articles` skill	`memory/check_seen` + `memory/mark_seen`
In-memory URL set	Redis-backed deduplication with TTL
Per-run dedup only	Cross-run persistent deduplication

Why Deprecated

Redundant: Deduplication is now built into collection skills
Better persistence: Memory MCP provides persistent deduplication with TTL
Simpler workflows: One fewer skill to coordinate
Consistency: All collection skills use the same deduplication mechanism
