"Getting banned from Claude for creating a Claude.md file is the 2025 equivalent of getting kicked out of a restaurant for reading the menu too carefully."
Hello Builders! 👋
🔥 Today's Top Story
A developer got banned from Claude for creating a Claude.md file – you know, those scaffolding files that tell AI assistants how to work with your codebase. The irony is thick enough to cut with a knife: using Claude's own recommended practice triggered their overzealous content policy system.
This sparked a 559-comment firestorm on HN because it hits a nerve every builder feels – we're building on platforms that can pull the rug out with zero warning. The automated moderation flagged legitimate dev work as policy violation, and getting unbanned requires navigating Kafka-esque support channels.

One More Thing...
Wild that Anthropic's dropping a new constitution the same week someone gets banned for a Claude.md file. The vibes are definitely shifting from "move fast" to "move carefully with 50 pages of guidelines."
What are you shipping this week? Any Claude.md casualties in your codebase?
Keep shipping,
P.S. If you're one of those engineers watching everyone else vibe code apps, maybe it's time to admit the vibes are working. Or at least grab some popcorn.
