chekusu/yobiru is a project that lets agents exchange messages, data, and files over Tailscale and wake each other up. The v0.7.17 release on GitHub adds the ability for the gateway to call webhooks directly. According to the release summary, this feature lets it wake agents running where there is no adapter. Beyond agent-to-agent communication, this change focuses on giving the gateway a path for waking agents.
Webhook calls are handled in a separate short-lived process. Up to 4 calls run at the same time, and each call has a 10-second deadline. Both a concurrency limit and a time limit therefore apply to how this feature behaves. The release summary explains that the backoff time increases when a call fails. Backoff time is the waiting period before retrying after a failure. These limits show that webhook calls are treated as separate calls that finish within a short time, not as work that runs indefinitely.
However, the provided release information contains no measured values for comparing throughput or stability. The maximum of 4 concurrent executions and the 10-second deadline can be confirmed, but these numbers alone cannot tell you the call volume a real environment can handle or the response latency. The behavior of a longer backoff on failure is also stated explicitly. It is therefore appropriate to view this change as the addition of a path for waking agents without an adapter, rather than as evidence of production performance and the impact of failures.
