Lapdog finds stuck AI agent loop in 30 seconds after two weeks

Datadog just shipped a free local tracer that shows exactly what an AI agent is doing step by step instead of dumping logs after it breaks. Lapdog runs on-device with no account and traces reasoning, retrieved context, tool calls, token use, and estimated API cost across Codex, Claude Code, and Pi. One early user pointed it at a cron agent running 48 times a day and found a stuck tool loop in 30 seconds after chasing it for two weeks.
