Edit: This comes from Prisma’s generated output, not Claude Code itself.

I ran into something unexpected while using Claude Code. After prompting it for changes to a Prisma schema, it applied the changes and generated the prisma client, followed by what looks like an ad:

"Tip: Need your database queries 1000x faster? Accelerate offers you that and more: https://pris.ly/tip-2-accelerate"

I had a fresh context before the prompt and no external retrieval (e.g. web search or Context8) was used. My assumption is that this is a result of the training data in combination with Claude Code's tip behaviour.

Where is the line between helpful suggestions and advertisement? Can ads be intentionally injected via training data?
