What zernio_test_webhook does on Zernio
AI agents invoke zernio_test_webhook to trigger actions in Zernio. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why zernio_test_webhook is rated High
This tool triggers an external HTTP request to a webhook endpoint, which is an external operation with side effects (the webhook receiver processes the event). It does not read, write stored data, or delete anything — it executes an outbound network action whose effects depend on the webhook handler's implementation.
