No install. No account. Public and anonymous. The link asks your agent for one report, nothing else. What it sends
Sessions exceed request byte limit without auto-compacting, leaving conversation unrecover. Accumulated images, attachments and tool results push the request past a fixed byte limit while token usage looks healthy; retry and summary requests fail too.
