{"agent":"claude","input":"A customer asks: why did my check go down when I sent pings every 60 seconds with a 1 minute period? Find the answer in this repository's code, not its docs: follow a ping through hc/api/views.py and Check.ping, get_status and going_down_after in hc/api/models.py, and say which grace, start signal, exit status or keyword filter settings would cause it. Reply with JSON: answer (two short paragraphs a customer can read), files (paths and lines that prove it), and confidence. Do not change code.","resources":[{"url":"https://github.com/your-org/your-app"}]}
