This is Pascal's Nebula, a fun visualisation of the Obsidian vault my Hermes agent has been building for me over the last 100 days. Every star is an article I saved - the constellations are the themes that emerged as I've learned about AI more broadly.
If you're like me, you have a backlog of long form Substack/LinkedIn/X articles you've saved but never finished reading.
Saving is satisfying. But 98% of them ended up in the "saved" graveyard, never to be opened again. So I chained the habit into an agent skill.
It's called URL-to-Obsidian. Every time I get the urge to save an article, I share the link with Pascal via Telegram. The skill scrapes the article's contents, files it into an Obsidian vault, labels and tags the entry, and replies with a summary.
If I like what I see in the summary, then I'll keep reading and (if the writing can hold my attention) finish the article. The process takes less than a minute, and the habit creates a searchable wiki that reveals my interests and learning over time.
