{"agent":"claude","input":"Error rates for the Phoenix app rose between 09:20 and 09:55 UTC today. Use the Grafana connection to read that window: the PromEx Phoenix request rate, error ratio and duration by route, Loki log lines with status 5xx grouped by request path and request id, and any alert rules that fired. Open the repository and compare the window with the commits of the last 7 days to lib/plausible_web/controllers/api and lib/plausible/stats; read the diff of every commit that touches a controller action or a stats query module on a failing path. You may run the matching ExUnit files under test/plausible_web/controllers/api to check a hypothesis. Write incident.md with a summary, a UTC timeline, the most likely cause with commit and file, the evidence for each claim (the PromQL, LogQL or command and its result), the causes you ruled out and every query you ran. Change no code and change nothing in Grafana.","connections":["grafana"],"resources":[{"url":"https://github.com/your-org/your-app"}]}
