Ask HN: Is There Any .llmignore?

Not that I have heard or seen. Many use the .gitignore for this.

What do you see it being used for? They are generally pretty good if you just put the focus/ignore in the AGENTS.md, though forcing is also valid and why I started building a custom coding agent (copilot did not force agents.md files in, let the llm decide, dumb imo)
