10911091Logged when Claude Code resolves an `@`-mention in a prompt. Not every mention emits an event: early-exit paths such as permission denials, oversized files, PDF reference attachments, and directory listing failures return without logging.
10921092
1093Each time Claude Code reads a prompt, it logs at most 100 events with a `mention_type` of `"agent"` and 100 with `"mcp_resource"`. Mentions past either limit still resolve but emit no event.
