Why this subagent

Cloud and LLM bills creep up quietly, and you usually find out at the end of the month when the invoice lands. This watcher checks both every morning and tells you what changed.

It diffs yesterday's spend against a rolling average, flags real anomalies, and names the service or model behind each jump. You get a daily spend diff in Slack before small leaks turn into a budget problem.

Compare today's per-service cloud and per-model LLM spend against the 7-day average, and return a diff listing every line that moved more than the threshold, with the dollar delta and likely driver.
