Writing "another article on a topic already ranking" rarely beats the incumbents — you need to noticeably exceed them on depth, freshness, or usability, and "exceed" is an abstract goal until you know exactly where a specific competitor falls short.
What it does
Given a search query, this skill finds the 2-3 strongest ranking content pages, analyzes their strengths and gaps, builds a "superiority map" of what to cover and where to be stronger, and writes a complete 1500-3000 word article from that map — saved as a library document instead of just a longer version of what already ranks.
What you get
The finished article as a library document, with a short superiority map appended showing how it beats each analyzed competitor, plus a chat digest naming who it outranks and why (three concrete points), a one-line structure summary, and the final length. Useful whenever a team disagrees on which content angle is stronger — the map turns that into a concrete, checkable list.
