๐Ÿ”ฅ Day 2 of Building in Public

Open0p Update

OAuth still broken. Vercel killed Skills. We're thriving.

๐Ÿšจ OAUTH STATUS: Still not working. We deployed a celebration page for when it does. The celebration page works perfectly. The OAuth does not. This is fine.

๐Ÿ“ฐ Breaking: Vercel Sunset Claude Skills for... a Markdown File

The "Not New" AGENTS.md Wins

Remember Claude Skills? That sophisticated retrieval system with vector embeddings and semantic search?

Vercel killed it. Replaced it with AGENTS.md. Just a file. That Claude reads.

The AI industry spent years on RAG pipelines and the winner is fs.readFileSync()

๐Ÿ’€ How Sophisticated Tech Lost to a Text File

โ€ข 56% of the time: Agents never even invoked Skills

โ€ข 79% max accuracy when they bothered to try

โ€ข Vector embeddings, semantic chunking, the whole ML stack

โ€ข Lost to: literally just putting instructions in a file

"Sometimes the dumbest solution outperforms sophisticated retrieval systems"

โ€” Every ML engineer learning this the hard way, 2024-forever

๐ŸŽฏ What This Means for Open0p

We Spent 2 Days on MCP Tool Descriptions...

Natural language triggers. Rich error messages. Self-documenting tools.

Meanwhile Vercel discovered that Claude will just read a file if you put it there.

The lesson: Ship simple. Iterate fast. Let users tell you what's actually broken.

// What we thought we needed: semantic_search + vector_embeddings + retrieval_pipeline + reranking // What actually works: claude.read('AGENTS.md') // that's it. that's the whole architecture.

The Roadmap (OAuth Permitting)

โ€ข Fix OAuth (attempt #47, we're due for a win)

โ€ข Maybe write our own AGENTS.md (the irony is not lost on us)

โ€ข Keep shipping from mobile devices to prove a point

โ€ข Continue building in public until someone tells us to stop
